[0002] A camera device is a device that takes photos or videos of a subject and is installed in optical equipment such as smartphones, drones, and vehicles.

[0003] In recent camera devices, in order to improve image quality in recent camera devices, an optical image stabilization (OIS) function that compensates for image jitter caused by user movement, an auto focus (AF) function that automatically adjusts the distance between an image sensor and a lens to align the focal length of the lens, and a zoom function that increases or decreases the magnification of a distant subject through a zoom lens are required.

[0004] In addition, the space for arranging the camera actuator as required for the ultra-thin and ultra-small camera module is greatly limited, and the camera module itself including the lens or the lens and the image sensor may have difficulty in ensuring sufficient space for tilting or moving for the action of OIS, etc. In addition, for a high-pixel camera, it is desirable to increase the size of the lens to increase the amount of light received, but increasing the size of the lens may be limited due to the space occupied by the actuator.

[0005] Furthermore, since an additional magnet or the like is provided to maintain the position of the reflecting member, there are problems such as magnetic field interference and difficulty in reducing weight.

[0378] Fig.57 is a perspective view of a camera module according to a second embodiment of the present invention, Fig.58 is an exploded perspective view of a camera module according to a second embodiment of the present invention, Fig.59 is from Fig.57 The view observed by AA′ in .

[0379] Reference Fig.57 and Fig.58 , the camera module 1000 according to the embodiment may include a cover CB, a first camera actuator 1100, a second camera actuator 1200, and a circuit board 1300. Here, the first camera actuator 1100 may be used as a first actuator, and the second camera actuator 1200 may be used as a second actuator interchangeably.

[0380] The cover CB may surround the first camera actuator 1100 and the second camera actuator 1200. A coupling force between the first camera actuator 1100 and the second camera actuator 1200 may be improved by the cover CB.

[0381] In addition, the cover CB may be made of a material that blocks electromagnetic waves. Therefore, the first camera actuator 1100 and the second camera actuator 1200 inside the cover CB may be easily protected.

[0382] In addition, the first camera actuator 1100 may be an optical image stabilizer (OIS) actuator.

[0383] The first camera actuator 1100 may include a fixed focal length lens disposed in a predetermined lens barrel (not shown). The fixed focal length lens may also be referred to as a "single focal length lens" or a "short lens".

[0384] The first camera actuator 1100 may change the optical path. As an example, the first camera actuator 1100 may vertically change the optical path through an internal optical member (e.g., a reflector). With this configuration, even if the thickness of the mobile terminal is reduced, a zoom function, an auto focus (AF) function, and an OIS function may be performed by changing the optical path by providing a lens structure larger than the thickness of the mobile terminal inside the mobile terminal.

[0385] The second camera actuator 1200 may be disposed at a rear end of the first camera actuator 1100. The second camera actuator 1200 may be coupled to the first camera actuator 1100. The mutual coupling may be performed by various methods.

[0386] In addition, the second camera actuator 1200 may be a zoom actuator or an auto focus (AF) actuator. For example, the second camera actuator 1200 may support one or more lenses and perform an auto focus function or a zoom function by moving the lenses according to a control signal from a predetermined control unit.

[0387] The circuit board 1300 may be disposed at a rear end of the second camera actuator 1200. The circuit board 1300 may be electrically connected to the second camera actuator 1200 and the first camera actuator 1100. In addition, the number of the circuit board 1300 may be plural.

[0388] Such a circuit board 1300 may be connected to the second housing of the second camera actuator 1200 and may have an image sensor. In addition, a base portion including an optical filter may be mounted on the circuit board 1300. A description of this will be given later.

[0389] The camera module according to the embodiment may include a single camera module or a plurality of camera modules. For example, the plurality of camera modules may include a first camera module and a second camera module.

[0390] The first camera module may include a single actuator or a plurality of actuators. For example, the first camera module may include a first camera actuator 1100 and a second camera actuator 1200 .

[0391] The second camera module may include an actuator (not shown) disposed in a predetermined housing (not shown) and capable of driving the lens unit. The actuator may be a voice coil motor, a microactuator, a silicon actuator, etc., and may be applied in various methods such as an electrostatic method, a thermal method, a bimorph method, and an electrostatic force method, but is not limited thereto. In addition, in this specification, the camera actuator may be referred to as an actuator, etc. In addition, a camera module consisting of a plurality of camera modules may be installed in various electronic devices such as mobile terminals.

[0392] Reference Fig.59 , the camera module according to the embodiment may include a first camera actuator 1100 performing an OIS function and a second camera actuator 1200 performing a zoom function and an AF function.

[0393] Light may be incident into the camera module through an opening provided on the upper surface of the first camera actuator 1100. That is, light may be incident into the first camera actuator 1100 along an optical axis direction (e.g., an X-axis direction), and the optical path may be changed to a vertical direction (e.g., a Z-axis direction) by an optical member. The light may pass through the second camera actuator 1200 and be incident into an image sensor IS (path) provided at one end of the second camera actuator 1200.

[0394] In this specification, the bottom surface refers to a side surface in the first direction. In addition, the first direction is the X-axis direction in the figure, and can be used interchangeably with the second axis direction. The second direction is the Y-axis direction in the figure, and can be used interchangeably with the first axis direction. The second direction is a direction perpendicular to the first direction. In addition, the third direction is the Z-axis direction in the figure, and can be used interchangeably with the third axis direction. The third direction is a direction perpendicular to the first direction and the second direction. Here, the third direction (Z-axis direction) corresponds to the direction of the optical axis, and the first direction (X-axis direction) and the second direction (Y-axis direction) are directions perpendicular to the optical axis, and can be tilted by the second camera actuator. A detailed description of this will be given later.

[0395] In addition, in the following description of the second camera actuator 1200, the optical axis direction corresponds to the optical path, which is the third direction (Z-axis direction), which will be described below.

[0396] Moreover, through this configuration, the camera module according to the embodiment can improve the space limitation of the first camera actuator and the second camera actuator by changing the optical path. That is, the camera module according to the present embodiment can expand the optical path while minimizing the thickness of the camera module in response to the change of the optical path. In addition, it should be understood that the second camera actuator can provide a wide range of magnification by controlling the focus in the expanded optical path, etc.

[0397] In addition, the camera module according to the present embodiment can implement OIS by controlling the optical path via the first camera actuator, and thus the occurrence of a shift or tilt phenomenon can be minimized, thereby obtaining optimal optical characteristics.

[0398] In addition, the second camera actuator 1200 may include an optical system and a lens driving unit. For example, in the second camera actuator 1200, at least one or more of a first lens assembly, a second lens assembly, a third lens assembly, and a guide pin may be provided.

[0399] In addition, the second camera actuator 1200 includes a coil and a magnet, thereby performing a zoom function at a high magnification.

[0400] For example, the first lens assembly and the second lens assembly may be moving lenses moved by coils, magnets, and guide pins, and the third lens assembly may be a fixed lens, but is not limited thereto. For example, the third lens assembly may perform a focuser function that forms light at a specific position; the first lens assembly may perform a variator function that re-forms an image formed in the third lens assembly as a light concentrator at another position. On the other hand, in the first lens assembly, the distance to the subject or the image distance may change a lot, so the change in magnification may be large, and the first lens assembly as a variable magnification may play an important role in changing the focal length or magnification of the optical system. On the other hand, the image formed by the first lens assembly as a variable amplifier may differ slightly based on the position. Therefore, the second lens assembly may perform a position compensation function for the image formed by the variable amplifier. For example, the second lens assembly may perform a compensator function that is used to accurately form an image formed by the first lens assembly as a variable amplifier at an actual image sensor position. For example, the first lens assembly and the second lens assembly may be driven by an electromagnetic force generated by the interaction between the coil and the magnet. The above information can be applied to the lens assembly, which will be described later.

[0401] On the other hand, according to the second embodiment of the present invention, when an OIS actuator (e.g., a first camera actuator) and an AF or zoom actuator (e.g., a second camera actuator) are provided, magnetic field interference with an AF or zoom magnet can be prevented during OIS driving. Since the driving magnet of the first camera actuator 1100 is provided separately from the second camera actuator 1200, magnetic field interference between the first camera actuator 1100 and the second camera actuator 1200 can be prevented. In this specification, OIS may be used interchangeably with terms such as hand shake correction, optical image stabilization, optical image correction, and shake correction.

[0406] Such a shielding can (not shown) can block or reduce electromagnetic waves generated from the outside. Therefore, it is possible to reduce the occurrence of malfunction of the rotating part 1140 or the first driving unit 1150.

[0412] In addition, the first housing side portion 1121 may include a first housing hole 1121 a . A first coil 1152 a to be described later may be disposed in the first housing hole 1121 a .

[0413] In addition, the second housing side portion 1122 may include a second housing hole 1122a. A second coil 1152b to be described later may be disposed in the second housing hole 1122a.

[0414] The first coil 1152a and the second coil 1152b may be coupled to the first substrate unit 1154. As an embodiment, the first coil 1152a and the second coil 1152b may be electrically connected to the first substrate unit 1154 so that a current can flow through the first substrate unit 1154. The current is an element of the electromagnetic force that enables the first camera actuator to tilt relative to the X-axis.

[0415] The third housing side portion 1123 may include a third housing hole 1123a. A third coil 1152c, which will be described later, may be disposed in the third housing hole 1123a. The third coil 1152 may be coupled to the first substrate unit 1154. In addition, a current may flow through the third coil 1152c electrically connected to the first substrate unit 1154. The current is an element of the electromagnetic force that enables the first camera actuator to tilt relative to the Y axis.

[0416] In addition, the first housing 1120 may include an accommodation portion 1125 formed by the first housing side portion 1121 to the fourth housing side portion 1124 . The mover 1130 may be disposed in the accommodation portion 1125 .

[0417] The mover 1130 includes a holder 1131 and an optical member 1132 mounted on the holder 1131 .

[0418] The holder 1131 and the optical member 1132 may be placed in the receiving portion 1125 of the first housing 1120. The holder 1131 may include first to fourth holder outer side surfaces corresponding to the first housing side 1121, the second housing side 1122, the third housing side 1123, and the fourth housing side 1124, respectively. In addition, the first drive coil 1152 may be disposed in a placement groove formed on the outer surface of the holder 1131. This will be described in detail later.

[0419] The optical member 1132 may be seated on the holder 1131. To this end, the holder 1131 may have a seating surface, and the seating surface may be formed of a receiving groove. The optical member 1132 may include a reflector disposed therein. However, it is not limited thereto.

[0420] In addition, the optical member 1132 can reflect light reflected from the outside (e.g., an object) into the camera module. In other words, the optical member 1132 can improve the space limitation of the first camera actuator and the first camera actuator by changing the path of the reflected light. Therefore, it should be understood that the camera module can also provide a wide range of magnifications while minimizing its thickness by extending the optical path.

[0421] The rotating part 1140 may include: an inclined guide unit 1141; a first yoke YK1 having a coupling force with the inclined guide unit 1141; and a second yoke YK2, which is disposed inside the inclined guide unit 1141 or the housing (particularly the fourth housing side). However, the first yoke YK1 and the second yoke YK2 are disposed inside the mover 1130, the inclined guide unit 1141, and the first housing 1120, so that a coupling force can be provided between the first housing 1120, the inclined guide unit 1141, and the mover 1130.

[0422] As described above, the tilt guide unit 1141 can be combined with the mover 1130 and the first housing 1120. Such a tilt guide unit 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 second axis, which will be described later.

[0423] The tilt guide unit 1141 may include first protrusions spaced apart from each other in a first direction (X-axis direction) and second protrusions spaced apart from each other in a second direction (Y-axis direction). In addition, the first protrusion and the second protrusion may protrude in opposite directions. A detailed description of this will be given later.

[0424] The first yoke YK1 may be disposed within the outer surface of the retainer 1131. For example, the first yoke YK1 may be disposed on the outer surface of the fourth retainer of the retainer 1131. With this configuration, the tilting guide unit 1141 may be pressed between the retainer 1131 and the first shell 1120 by the magnetic force (e.g., attraction) between the first yoke YK1 and the second yoke YK2. Therefore, the tilting guide unit 1141 and the retainer 1131 in the first shell 1120 may be spaced apart from the bottom surface of the shell in the accommodating portion 1125. That is, the tilting guide unit 1141 and the retainer 1131 may be coupled to the first shell 1120. However, as described above, the first yoke YK1 and the second yoke YK2 may be magnets having different polarities or the same polarity, or may be yokes, etc., and may be made of materials having attraction or repulsion to each other.

[0425] The first driving unit 1150 includes a driving magnet 1151, a driving coil 1152, a yoke (not shown), a hall sensor unit 1153, and a first substrate unit 1154. The first driving unit 1150 may move, rotate, or tilt the mover 1130.

[0426] The driving magnet 1151 may include a plurality of magnets. As an example, the driving magnet 1151 may include a first magnet 1151a, a second magnet 1151b, and a third magnet 1151c.

[0427] The first magnet 1151a, the second magnet 1151b, and the third magnet 1151c may be respectively disposed on the outer side surface of the holder 1131. In addition, the first magnet 1151a and the second magnet 1151b may be disposed facing each other. The third magnet 1151c may be disposed on the bottom surface of the holder 1131, that is, on the outer side surface of the third holder. A detailed description of this will be given later.

[0428] The driving coil 1152 may include a plurality of coils. As an embodiment, the driving coil 1152 may include a first coil 1152a, a second coil 1152b, and a third coil 1152c.

[0429] The first coil 1152a may be disposed to correspond to the first magnet 1151a. That is, the first coil 1152a may face the first magnet 1151a. Therefore, as described above, the first coil 1152a may be disposed in the first housing hole 1121a of the first housing side portion 1121.

[0430] In addition, the second coil 1152b can be arranged to correspond to the second magnet 1151b. That is, the second coil 1152b can be arranged to face the second magnet 1151b. Therefore, as described above, the second coil 1152b can be arranged in the second housing hole 1122a of the second housing side portion 1122.

[0431] In addition, the first coil 1152a can be arranged to face the second coil 1152b. That is, the first coil 1152a can be symmetrically arranged relative to the second coil 1152b in the first direction (X-axis direction). This can also be applied to the first magnet 1151a and the second magnet 1151b. That is, the first magnet 1151a and the second magnet 1151b can be symmetrically arranged about the first direction (X-axis direction). In addition, the first coil 1152a, the second coil 1152b, the first magnet 1151a and the second magnet 151b can be arranged to overlap at least partially in the second direction (Y-axis direction). With this configuration, the X-axis tilt can be accurately performed by the electromagnetic force between the first coil 1152a and the first magnet 1151a and the electromagnetic force between the second coil 1152b and the second magnet 1151b without tilting to one side.

[0432] The third coil 1152c may be disposed to correspond to the third magnet 1151c. For example, the third coil 1152c may be disposed in the third housing hole 1123a of the third housing side portion 1123. The third housing hole 1123a may have an area different from that of the first housing hole and the second housing hole. Therefore, the Y-axis tilting performed by the third coil 1152c may be easily performed.

[0433] In addition, the third coil 1152c may be disposed on a bisector between the first coil 1152a and the second coil 1152b. With this configuration, Y-axis tilting may be performed in a balanced manner without tilting to one side by an electromagnetic force generated by a current flowing through the third coil 1152c.

[0434] A yoke (not shown) may be provided between the driving magnet 1151 and the retainer 1131. The yoke (not shown) is provided on the first retainer outer side surface and the second retainer outer side surface of the retainer 1131 so as to facilitate coupling of the driving magnet to the retainer 1131. For example, the yoke (not shown) may be provided in a seating groove provided on the outer side surface of the retainer and may have an attractive force with the driving magnet 1151. That is, the yoke (not shown) may improve the coupling force between the driving magnet 1151 and the retainer 1131.

[0435] The Hall sensor unit 1153 may include a plurality of Hall sensors. As an embodiment, the Hall sensor unit 1153 may include a first Hall sensor 1153a and a second Hall sensor 1153b. The first Hall sensor 1153a may be disposed inside or outside the first coil 1152a or the second coil 1152b. The first Hall sensor 1153a may detect a change in magnetic flux inside the first coil 1152a or the second coil 1152b. Therefore, the first Hall sensor 1153a may perform position sensing on the first magnet 1151a and the second magnet 1151b. In addition, the second Hall sensor 1153b may be disposed inside or outside the third coil 1152c. The second Hall sensor 1153b may detect the position of the third coil 1152c. The first camera actuator according to the present embodiment may control the X-axis or Y-axis tilt in this way. The Hall sensor unit or the Hall sensor may include a plurality of sensors.

[0436] The first substrate unit 1154 may be disposed below the first driving unit 1150. The first substrate unit 1154 may be electrically connected to the driving coil 1152 and the Hall sensor unit 1153. For example, current is applied to the driving coil 1152 through the first substrate unit 1154, and accordingly, the mover 1130 may be tilted on the X-axis or the Y-axis. For example, the first substrate unit 1154 may be combined with the driving coil 1152 and the Hall sensor unit 1153 by SMT. However, it is not limited to this method.

[0437] The first substrate unit 1154 is disposed between the shielding can (not shown) and the first shell 1120, and can be combined with the shielding can and the first shell 1120. As described above, the combination can be performed in various ways as described above. In addition, by combining, the drive coil 1152 and the Hall sensor unit 1153 can be disposed in the outer side surface of the first shell 1120.

[0438] Such a first substrate unit 1154 may include a circuit board such as a rigid printed circuit board (rigid PCB), a flexible printed circuit board (flex PCB), and a rigid-flexible printed circuit board (rigid-flex PCB), etc., which has a wiring pattern that can be electrically connected. However, it is not limited to these types.

[0439] Fig.62 is a perspective view of a first housing in a first camera actuator according to a second embodiment of the present invention, Fig.63 is a side view of a first housing in a first camera actuator according to a second embodiment of the present invention, Fig.64 is from Fig.63 The cross-sectional view observed at M-M' in Fig.65 is from Fig.63 The cross-sectional view observed at N-N'.

[0440] Reference Fig.62 , the first shell 1120 may include a first shell side 1121 , a second shell side 1122 , a third shell side 1123 and a fourth shell side 1124 .

[0441] The first case side 1121 and the second case side 1122 may be disposed to face each other. In addition, the third case side 1123 and the fourth case side 1124 may be disposed between the first case side 1121 and the second case side 1122.

[0442] The third case side 1123 may be in contact with the first case side 1121, the second case side 1122, and the fourth case side 1124. The third case side 1123 may be a bottom surface of the first case 1120.

[0443] In addition, the first housing side portion 1121 may include a first housing hole 1121 a . A first coil 1152 a to be described later may be disposed in the first housing hole 1121 a .

[0444] In addition, the second housing side portion 1122 may include a second housing hole 1122a. A second coil 1152b to be described later may be disposed in the second housing hole 1122a.

[0445] In addition, the second housing side 1122 or the first housing side 1121 may include a control element groove. As an embodiment, the second housing side 1122 may include a control element groove. In addition, a driver, a control element, a processor, etc. electrically connected to the substrate may be disposed in the control element groove. Alternatively, a circuit board of the first camera actuator may be disposed on an outer surface of the first housing side 1121 or the second housing side 1122, and the circuit board may be connected to the control element.

[0446] In addition, the first coil and the second coil may be combined with the first substrate unit. In an embodiment, the first coil and the second coil may be electrically connected to the first substrate unit so that a current can flow. The current is a component of the electromagnetic force that enables the first camera actuator to tilt relative to the X-axis.

[0447] In addition, the third housing side 1123 may be disposed between the first housing side 1121 and the second housing side 1122. The third housing side 1123 may be the bottom of the first housing 1120. The third coil is disposed in the third housing hole 1123a of the third housing side 1123, and the current flowing through the third coil is an element of the electromagnetic force capable of tilting the first camera actuator relative to the Y-axis.

[0448] In addition, the fourth case side 1124 may include second protrusion grooves PH2 disposed symmetrically about the center.

[0449] Further observation Figure 63 to Figure 65 , there are multiple second protrusion grooves PH2, which can accommodate the second protrusion of the tilt guide unit. In the present specification, it is explained that multiple first protrusion grooves PH1 overlap each other in the second direction (Y-axis direction), and multiple second protrusion grooves overlap each other in the first direction (X-axis direction). However, when the positions of the first protrusion and the second protrusion are changed, the positions of the first protrusion and the second protrusion can also be interchanged corresponding to the positions of the first protrusion and the second protrusion. Therefore, in the first camera actuator according to the embodiment, the housing and the retainer can each include a different one of the first protrusion groove in which the first protrusion is accommodated and the second protrusion groove in which the second protrusion is accommodated.

[0450] In addition, a second additional groove PH2H surrounding the second protrusion groove PH2 may be disposed on the outside of the second protrusion groove PH2. The second additional groove PH2H may be disposed on the inner side surface of the fourth shell side portion 1124. In addition, the second additional groove PH2H may surround the second protrusion groove PH2 disposed inside the fourth shell side portion 1124. With this configuration, a lubricating member for accommodating the second protrusion of the inclined guide unit may be disposed inside the second protrusion groove PH2. At this time, the lubricating member (e.g., grease) may overflow due to the impact between the second protrusion and the second protrusion groove PH2. The second additional groove PH2H is capable of accommodating the overflowed lubricating member. Therefore, even if the lubricating member overflows due to a collision, it will not move to the inclined guide unit. Therefore, the inclined guide unit and the shell may not be connected by the lubricating member. Therefore, the rotation drive of the inclined guide unit can be accurately performed without being hindered by the lubricating member.

[0451] In addition, the first housing 1120 may include an accommodation portion 1125 formed by the first housing side portion 1121 to the fourth housing side portion 1124 . The mover 1130 may be disposed in the accommodation portion 1125 .

[0452] In addition, the first housing 1120 or the first camera actuator may include a yoke groove. The yoke groove may include a first yoke groove YKH1 and a second yoke groove YKH2. In addition, as described above, the yoke portion may be disposed in the yoke groove. For example, the first yoke YK1 may be disposed in the first yoke groove YKH1. The second yoke YK2 may be disposed in the second yoke groove YKH2. Therefore, the first yoke YK1 and the second yoke YK2 may be disposed inside the first housing 1120. In other words, the first yoke YK1 and the second yoke YK2 may be coupled to the first housing 1120.

[0453] The first yoke groove YKH1 may be arranged on the inner side of the first shell hole 1121a of the first shell side 1121. The second yoke groove YKH2 may be arranged on the inner side of the second shell hole 1122a of the second shell side 1122. The first yoke groove YKH1 and the second yoke groove YKH2 may be arranged between the first shell hole 1121a and the second shell hole 1122a. In addition, the first yoke groove YKH1 may not overlap with the first shell hole 1121a in the optical axis direction (Z-axis direction). Similarly, the second yoke groove YKH2 may not overlap with the second shell hole 1122a in the optical axis direction. Therefore, the first yoke groove YKH1 may not overlap with the first coil in the optical axis direction. In addition, the second yoke groove YKH2 may not overlap with the second coil in the optical axis direction.

[0454] With this configuration, the first yoke may not overlap with the first coil along the optical axis. In addition, the second yoke may not overlap with the second coil along the optical axis. Therefore, the influence of the first yoke and the second yoke on the first coil and the second coil can be minimized. Therefore, accurate tilt drive can be performed by the first coil and the second coil.

[0455] In addition, the third housing hole 1123a can be arranged between the first yoke groove YKH1 and the second yoke groove YKH2. The first yoke groove YKH1 and the second yoke groove YKH2 can be symmetrically arranged about the third housing hole 1123a. Therefore, the influence of the first yoke groove YKH1 and the second yoke groove YKH2 on the third coil arranged in the third housing hole 1123a can be minimized.

[0456] Furthermore, the first yoke groove YKH1 and the second yoke groove YKH2 may be disposed on the optical axis direction side relative to the second protrusion groove PH2 or the second additional groove PH2H. Furthermore, the first yoke groove YKH1 and the second yoke groove YKH2 may not overlap with the optical axis direction relative to the second protrusion groove PH2 or the second additional groove PH2H.

[0457] Fig.66 is a perspective view of optical components of a first camera actuator according to a second embodiment of the present invention.

[0458] The optical member 1132 may be mounted on the holder. The optical member 1132 may be a right angle prism as a reflection unit, but is not limited thereto. For example, the optical member 1132 may include various optical elements that change the optical path.

[0459] As an embodiment, the optical member 1132 may have a protrusion (not shown) on a portion of the outer surface. The optical member 1132 may be easily coupled to the holder through the protrusion (not shown). In addition, the holder may be coupled to the optical member 1132 by having a groove or a protrusion.

[0460] In addition, the bottom surface 1132b of the optical member 1132 can be placed on the placement surface of the holder. Therefore, the bottom surface 1132b of the optical member 1132 can correspond to the placement surface of the holder. As an embodiment, the bottom surface 1132b can be made of an inclined surface in the same manner as the placement holder. Therefore, it is possible to prevent the optical member 1132 from being separated from the holder when the prism moves according to the movement of the holder.

[0461] In addition, a groove or protrusion is formed on the bottom surface 1132b of the optical member 1132, and an adhesive member is applied so that the optical member 1132 can be combined with the holder. Alternatively, the holder can be combined with the optical member 1132 by applying the adhesive member to the groove or protrusion of the holder.

[0462] In addition, as described above, the optical member 1132 may have a structure capable of reflecting light reflected from the outside (e.g., an object) into the camera module. As an embodiment, the optical member 1132 may be composed of a single reflector. In addition, the optical member 1132 can improve the space limitations of the first camera actuator and the second camera actuator by changing the path of the reflected light. Therefore, it should be understood that the camera module can provide a wide range of magnifications by extending the optical path while minimizing the thickness. In addition, it should be understood that the camera module including a camera actuator according to the present embodiment can provide a wide range of magnifications by extending the optical path while minimizing the thickness.

[0463] Fig.67 is a perspective view of a retainer according to a second embodiment of the present invention, Fig.68 is a side view of a retainer according to a second embodiment of the present invention, Fig.69 is another side view of a retainer according to a second embodiment of the present invention, Fig.70 is a bottom view of a retainer according to a second embodiment of the present invention, Fig.71 is another side view of a holder according to a second embodiment of the present invention.

[0464] Reference Figures 67 to 71, the holder 1131 according to the embodiment may include a placement surface 1131k, on which the optical member may be placed. The placement surface 1131k may be a slope. In addition, the holder 1131 may include a claw portion (not shown) located on the placement surface 1131k. The claw portion (not shown) in the holder 1131 may prevent the movement of the optical member 1132. In addition, the placement surface 1131k may include a plurality of grooves, and the adhesive member may be applied to the grooves. Therefore, the optical member may be easily bonded to the placement surface 1131k. At this time, the optical member may be bonded to the adhesive member at the edge of the placement surface 1131k. Alternatively, the optical member may be bonded to the adhesive member inside the holder groove 1131SG of the holder 1131. Therefore, the bottom surface or the reflective surface of the optical member may be spaced apart from the placement surface 1131k of the holder 1131 by a predetermined distance. For example, except for the edge, the placement surface 1131k of the holder 1131 may have a space separated from the reflective surface of the optical member. In addition, the holder 1131 according to the embodiment may include a cavity CV. The cavity CV may be provided between the first holder outer side surface 1131S1 and the second holder outer side surface 1131S2, which will be described later. The optical member may be seated in the cavity CV.

[0465] The retainer 1131 may include a retainer hole 1131h that penetrates at least a portion of the retainer 1131 in the second direction (Y-axis direction). The retainer hole 1131h is symmetrical with the control element hole in the second direction (Y-axis direction), so that the heat dissipation efficiency of the heat generated from the control element can be improved. In addition, since the weight of the retainer 1131 is reduced due to the retainer hole 1131h, the driving efficiency of the X-axis or Y-axis tilt of the mover can be improved. In addition, the space in which the first yoke groove and the second yoke groove are formed can be ensured by the retainer hole 1131h.

[0466] In addition, the holder 1131 may include a plurality of outer side surfaces. For example, the holder 1131 may include a first holder outer side surface 1131S1, a second holder outer side surface 1131S2, a third holder outer side surface 1131S3, and a fourth holder outer side surface 1131S4.

[0467] The first holder outer side surface 1131S1 may be disposed to face the second holder outer side surface 1131S2. That is, the first holder outer side surface 1131S1 may be disposed symmetrically with the second holder outer side surface 1131S2 with respect to the first direction (X-axis direction).

[0468] The first holder outside surface 1131S1 may face the first case side 1121. Also, the second holder outside surface 1131S2 may face the second case side 1122.

[0469] In addition, the first holder outer side surface 1131S1 may include a first seating groove 1131S1a. The second holder outer side surface 1131S2 may include a second seating groove 1131S2a. The first seating groove 1131S1a and the second seating groove 1131S2a may be symmetrically disposed with respect to the first direction (X-axis direction).

[0470] In addition, the first magnet may be disposed in the first seating groove 1131S1a, and the second magnet may be disposed in the second seating groove 1131S2a. Corresponding to the positions of the first seating groove 1131S1a and the second seating groove 1131S2a, the first magnet and the second magnet may also be symmetrically disposed about the first direction (X-axis direction).

[0471] As described above, due to the positions of the first and second mounting grooves and the first and second magnets, the electromagnetic force caused by the magnets is the same on the first holder outer surface S1231S1 and the second holder outer surface 1131S2, and can be provided on the same axis. For example, the area applied to the first holder outer surface S1231S1 (e.g., the part with the strongest electromagnetic force) and the area applied to the second holder outer surface S1231S2 (e.g., the part with the strongest electromagnetic force) can be set on an axis parallel to the second direction (Y-axis direction). Therefore, the X-axis tilt can be accurately performed.

[0472] The third retainer outer side surface 1131S3 contacts the first retainer outer side surface 1131S1 and the second retainer outer side surface 1131S2, and can be an outer side surface extending from the first retainer outer side surface 1131S1 and the second retainer outer side surface 1131S2 in the second direction (Y-axis direction). In addition, the third retainer outer side surface 1131S3 can be arranged between the first retainer outer side surface 1131S1 and the second retainer outer side surface 1131S2.

[0473] The third holder outside surface 1131S3 may be a bottom surface of the holder 1131. The third holder outside surface 1131S3 may face the third case side.

[0474] In addition, the third retainer outer side surface 1131S3 may include an extension stopper (not shown) extending downward. Therefore, it is possible to set a limit on the range of movement of the retainer 1131 in the Y-axis tilt direction or in the first direction (X-axis direction) or up and down movement within the housing, and at the same time, it is possible to prevent damage caused by movement of the retainer 1131.

[0475] In addition, the third retainer outer side surface 1131S3 may include a third seating groove 1131S3a. The third magnet may be disposed in the third seating groove 1131S3a. For example, the area of ​​the third seating groove 1131S3a may be different from the areas of the first seating groove 1131S1a and the second seating groove 1131S2b. The area of ​​the third seating groove 1131S3a may be greater than the areas of the first seating groove 1131S1a and the second seating groove 1131S2b. Therefore, rotation in the first direction (X-axis direction) or tilting in the second direction (Y-axis direction) may be easily performed by the third magnet disposed in the third seating groove 1131S3a.

[0476] The fourth retainer outer side surface 1131S4 contacts the first retainer outer side surface 1131S1 and the second retainer outer side surface 1131S2, and may be an outer side surface extending from the third retainer outer side surface 1131S3 in the first direction (X-axis direction). In addition, the fourth retainer outer side surface 1131S4 may be disposed between the first retainer outer side surface 1131S1 and the second retainer outer side surface 1131S2. The fourth retainer outer side surface 1131S4 may be disposed on the third retainer outer side surface 1131S3.

[0477] The fourth holder outer side surface 1131S4 may be disposed to face the first surface of the inclined guide unit.

[0478] The fourth retainer outer side surface 1131S4 may include a first protrusion groove PH1, which is spaced apart in the first direction (X-axis direction) around the center of the fourth retainer outer side surface. The first protrusion of the tilting guide unit may be placed in the first protrusion groove PH1. The retainer 1131 can rotate in the X-axis direction or tilt in the Y-axis direction relative to the first protrusion. In addition, the retainer 1131 can rotate in the Y-axis direction or tilt in the X-axis direction relative to the second protrusion.

[0479] As described above, the number of the first protrusion grooves PH1 is multiple, and the first protrusion grooves PH1 can overlap in the second direction (Y-axis direction). Therefore, when the mover is tilted in the Y-axis direction or rotated in the first direction (X-axis direction), it can be accurately performed without tilting to one side. As an embodiment, the OIS function can be accurately performed.

[0480] In addition, the first additional groove PH1H surrounding the first protrusion groove PH1 may be provided on the outside of the first protrusion groove PH1. The first additional groove PH1H may be provided on the outer side surface 1131S4 of the fourth retainer. In addition, the first additional groove PH1H may surround the first protrusion groove PH1 provided on the outer side surface 1131S4 of the fourth retainer. With this structure, a lubricating member may be provided, which is used to place the first protrusion of the inclined guide unit in the first protrusion groove PH1. At this time, the lubricating member (e.g., grease) may overflow due to the impact between the second protrusion and the first protrusion groove PH1. The first additional groove PH1H can accommodate the overflowed lubricating member. Therefore, even if the lubricating member overflows due to a collision, the lubricating member will not move to the inclined guide unit. Therefore, the inclined guide unit and the housing may not be connected by the lubricating member. Therefore, the rotation drive of the inclined guide unit can be accurately performed without being hindered by the lubricating member.

[0481] Furthermore, the first and second yoke grooves may be disposed on the optical axis direction side relative to the first protrusion groove PH1 or the first additional groove PH1H. Furthermore, the first and second yoke grooves may not overlap in the optical axis direction with reference to the first protrusion groove PH1 or the first additional groove PH1H.

[0482] In addition, the fourth holder outer side surface 1131S4 may further include outer side surface grooves disposed spaced apart from each other in the first direction (X-axis direction) relative to the first additional groove PH1H. The outer side surface grooves may include a first outer side surface groove 1131S4g1 and a second outer side surface groove 1131S4g2.

[0483] The first outer side surface groove 1131S4g1 is disposed above the first additional groove PH1H, and the second outer side surface groove 1131S4g2 may be disposed below the first additional groove PH1H. That is, the first outer side surface groove 1131S4g1 may be disposed above the second outer side surface groove 1131S4g2.

[0484] The first outer surface groove 1131S4g1 and the second outer surface groove 1131S4g2 can be arranged at the end of the outer surface 1131S4 of the fourth retainer in the vertical direction. With this structure, the first outer surface groove 1131S4g1 and the second outer surface groove 1131S4g2 can be tilted with respect to the two axes of the retainer 1131 to avoid the impact between the retainer and the housing. Therefore, the reliability of the retainer 1131 can be improved.

[0485] In addition, in the holder 1131 according to the present embodiment, the area of ​​the first outer surface groove 1131S4g1 may be different from the area of ​​the second outer surface groove 1131S4g2. For example, the area of ​​the first outer surface groove 1131S4g1 on the plane XY may be smaller than the area of ​​the second outer surface groove 1131S4g2 on the plane XY. Therefore, as the holder 1131 moves toward the optical axis relative to the placement surface 1131k, the cross-sectional area of ​​the holder 1131 on the plane XY decreases, and the cross-sectional area of ​​the cavity increases toward the optical axis, and therefore, the rigidity and durability of the holder 1131 according to the areas of the outer surface grooves 1131S4g1 and 1131S4g2 of the outer surface 1131S4 of the fourth holder, etc. can be maintained.

[0486] In addition, the holder 1131 according to the embodiment may further include stoppers VS and LS The stoppers may contact the first holder outer side surface 1131S1 and the second holder outer side surface 1131S2 .

[0487] The stoppers may include an upper stopper VS disposed on the bottom surface of the cavity CV and a lower stopper LS disposed at a lower portion of the bottom surface of the cavity CV. In an embodiment, the bottom surface of the cavity CV may correspond to the seating surface 1131k. That is, the cavity may be surrounded by the first retainer outer side surface 1131S1, the second retainer outer side surface 1131S2, and the seating surface 1131k.

[0488] In the stopper according to the embodiment, each of the upper stopper VS and the lower stopper LS may be disposed at the end of the first retainer outer side surface 1131S1 and the second retainer outer side surface 1131S2 in the third direction (Z-axis direction) or the optical axis direction. In addition, the upper stopper VS and the lower stopper LS may have the same or different cross-sectional areas or volumes on the plane XZ.

[0489] As an embodiment, the upper stopper VS and the lower stopper LS may be arranged at intervals from each other in the first direction (X-axis direction). As an embodiment, the first retainer outer side surface 1131S1 and the second retainer outer side surface 1131S2 may include an upper area UA and a lower area BA divided into two equal parts in the first direction (X-axis direction). For example, the upper area UA may be arranged above the lower area BA. The upper stopper VS may be arranged in the upper area UA. That is, the upper stopper VS may contact the upper area UA and overlap with the upper area UA in the second direction (Y-axis direction). In addition, the lower stopper LS may be arranged in the lower area BA. In addition, the lower stopper LS may contact the lower area BA and overlap with the lower area BA in the second direction (Y-axis direction). For example, the upper stopper VS may be arranged to overlap with the second area S2 and the upper area UA in the second direction (Y-axis direction). In addition, the lower stopper VS may be arranged to overlap with the second area S2 and the lower area BA in the second direction (Y-axis direction). Therefore, the upper stopper VS may overlap the optical member in the second direction (X-axis direction).

[0490] In addition, as an embodiment, the lower stopper LS may be disposed closer to the outer side surface 1131S3 of the third retainer than the upper stopper VS. Moreover, the area in the upper area UA that overlaps with the cavity or the optical member in the second direction (Y-axis direction) may be larger than the area in the lower area BA that overlaps with the cavity CV or the optical member in the second direction (Y-axis direction). Therefore, as the movement moves toward the end, the amount of deformation due to the impact in the upper area UA may be greater than the amount of deformation due to the impact in the lower area BA. In other words, the amount of deformation due to the impact at the end of the lower area BA may be smaller than the amount of deformation due to the impact in the upper area UA.

[0491] The upper stopper VS and the lower stopper LS may extend from ends of the first holder outer side surface 1131S1 and the second holder outer side surface 1131S2 in a direction opposite to the third direction.

[0492] In addition, the upper stopper VS and the lower stopper LS can extend inward or toward the cavity CV. With this configuration, when the retainer 1131 is tilted in the second direction (Y-axis direction) or tilted in the first direction, damage caused by the impact between the retainer and the shell can be suppressed by the upper stopper VS and the lower stopper LS.

[0493] A plurality of groove inner side surfaces may be included. For example, the holder 1131 may include a first holder inner side surface 1131I1 and a second holder inner side surface 1131I2 that contact the cavity CV or the seating surface 1131k.

[0494] The first holder inner surface 1131I1 and the second holder inner surface 1131I2 may be arranged to face each other in the second direction (Y-axis direction). For example, the first holder inner surface 1131I1 and the second holder inner surface 1131I2 may be arranged to face each other without an optical member or in the holder 1131. In addition, the cavity CV may be arranged between the first holder inner surface 1131I1 and the second holder inner surface 1131I2.

[0495] In addition, the retainer 1131 according to the embodiment may include a retainer groove 1131SG. The number of the retainer groove 1131SG may be multiple, and a prevention portion may be arranged. In addition, the retainer groove 1131SG may be arranged on at least one of the first retainer inner surface 1131I1 and the second retainer inner surface 1131I2. For example, the retainer groove 1131SG may include a first retainer groove 1131SG1 and a second retainer groove 1131SG2. The first retainer groove 1131SG1 may be arranged on the first retainer inner surface 1131I1, and the second retainer groove 1131SG2 may be arranged on the second retainer inner surface 1131I2.

[0496] In addition, the first holder groove 1131SG1 and the second holder groove 1131SG2 may overlap in the second direction (Y-axis direction). In addition, the first holder groove 1131SG1 and the second holder groove 1131SG2 may be symmetrically disposed with respect to the optical member or the first direction (X-axis direction).

[0497] Therefore, when at least a portion of the preventing portion is disposed in the first and second retainer grooves 1131SG1 and 1131SG2 , the tilting guide unit may be prevented from falling between the housing and the mover by the preventing portion.

[0498] The first and second holder grooves 1131SG1 and 1131SG2 may be disposed in the upper area UA. Therefore, the preventing portion of the cover may be easily disposed in the first and second holder grooves 1131SG1 and 1131SG2.

[0499] In addition, the retainer according to the embodiment may include a retainer groove 1131SG and adjacent engagement grooves 1131CG1 and 1131CG2. The engagement grooves 1131CG1 and 1131CG2 may be disposed adjacent to the retainer groove 1131SG in the optical axis direction. For example, the engagement grooves 1131CG1 and 1131CG2 may overlap with at least a portion of the retainer groove 1131SG in the optical axis direction.

[0500] According to an embodiment, there may be a plurality of engagement grooves, and may include a first engagement groove 1131CG1 and a second engagement groove 1131CG2. Each of the first engagement groove 1131CG1 and the second engagement groove 1131CG2 may be multiple. For example, each of the first engagement groove 1131CG1 and the second engagement groove 1131CG2 is symmetrically arranged with respect to the vertical direction or the optical member.

[0501] In addition, the first and second engaging grooves 1131CG1 and 1131CG2 may be provided on the first and second holder inner side surfaces 1131I1 and 1131I2. In addition, the first and second engaging grooves 1131CG1 and 1131CG2 may be provided in the upper area UA like the holder groove 1131SG.

[0502] The first engaging groove 1131CG1 and the second engaging groove 1131CG2 may be disposed to be spaced apart from each other in the optical axis direction, and the holder groove 1131SG may be disposed between the first engaging groove 1131CG1 and the second engaging groove 1131CG2.

[0503] In addition, an adhesive member may be applied inside the first engagement groove 1131CG1 and the second engagement groove 1131CG2. Therefore, since the preventing portion in the retainer groove 1131SG contacts the inner side surface of the retainer groove 1131SG, even if an impact is applied to the retainer, the bonding between the optical member and the retainer may be maintained by the adhesive member inside the first adhesive hole and the second adhesive hole adjacent to the retainer groove 1131SG1. Therefore, separation between the retainer and the optical member may be prevented.

[0504] Furthermore, in the first camera actuator according to the embodiment, the holder 1131 may include a holder protrusion 1131 p extending upward on the upper surface.

[0505] The retainer protrusion 1131p may be disposed adjacent to the first engagement groove 1131CG1 and the second engagement groove 1131CG2. For example, the retainer protrusion 1131p may be disposed along the edges of the first engagement groove 1131CG1 and the second engagement groove 1131CG2. Therefore, through the retainer protrusion 1131p, the adhesive member applied inside the first engagement groove 1131CG1 and the second engagement groove 1131CG2 does not overflow from the first engagement groove 1131CG1 and the second engagement groove 1131CG2.

[0506] Furthermore, the holder protrusion 1131p may function as a stopper to be inclined in the first direction (X-axis direction) or the second direction (Y-axis direction).

[0507] Fig.72 is a perspective view of a tilt guide unit of a first camera actuator according to a second embodiment of the present invention, Fig.73 is with Fig.72 The stereogram in different directions, Fig.74 is from Fig.72 Cross-sectional view observed along line F-F'.

[0508] Reference Figure 72 to Figure 74 , the rotating part 1140 according to the embodiment may include an inclined guide unit 1141 and a yoke. The yoke may include a first yoke YK1 and a second yoke YK2. The first yoke YK1 and the second yoke YK2 may be arranged accordingly with respect to the inclined guide unit 1141. For example, the guide unit 1141 may be arranged in an area between the first yoke YK1 and the second yoke YK2. In addition, the first yoke YK1 and the second yoke YK2 may provide a coupling force between the mover, the inclined guide unit 1141 and the housing by applying the same contents as above.

[0509] First, the tilt guide unit 1141 may include: a base BS; a first protrusion PR1 protruding from a first surface 1141a of the base BS; and a second protrusion PR2 protruding from a second surface 1141b of the base BS. In addition, according to the structure, the first protrusion and the second protrusion may have opposite surfaces, but will be described below with reference to the accompanying drawings. In addition, the first protrusion PR1 and the second protrusion PR2 may be formed integrally with the base BS or separately, and as shown in the figure, the first protrusion PR1 and the second protrusion PR2 may have a spherical or hemispherical shape like a ball.

[0510] First, the base BS may include a first surface 1141a and a second surface 1141b facing the first surface 1141a. That is, the first surface 1141a may be spaced apart from the second surface 1141b in the third direction (Z-axis direction), and the first surface 1141a and the second surface 1141b may be outer surfaces facing or opposite to each other inside the tilt guide unit 1141. The first surface 1141a is disposed facing the outer surface of the fourth holder (or the side of the fourth housing), and the second surface 1141b may be disposed facing the outer surface of the fourth holder (or the side of the fourth housing).

[0511] The first surface 1141 a and the second surface 1141 b may include a plurality of holes or grooves, and the weight of the tilt guide unit 1141 may be reduced through the holes or grooves.

[0512] The tilt guide unit 1141 may include a first protrusion PR1 extending to one side on the first surface 1141a. According to an embodiment, the first protrusion PR1 may protrude from the first surface 1141a toward the outer side surface of the fourth holder. The first protrusion PR1 is plural and may include a 1-1 protrusion PR1a and a 1-2 protrusion PR1b.

[0513] The 1-1 protrusion PR1a and the 1-2 protrusion PR1b may be arranged side by side in the second direction (Y-axis direction). In other words, the 1-1 protrusion PR1a and the 1-2 protrusion PR1b may overlap in the second direction (Y-axis direction). In addition, in the embodiment, the 1-1 protrusion PR1a and the 1-2 protrusion PR1b may be bisected by a virtual line extending in the second direction (Y-axis direction).

[0514] In addition, the 1-1 protrusion PR1a and the 1-2 protrusion PR1b have a curvature, for example, may be hemispherical. In addition, in this specification, the first protrusion and the second protrusion may refer to hemispherical protrusions or balls placed in the grooves. In addition, the 1-1 protrusion PR1a and the 1-2 protrusion PR1b may contact the first protrusion groove of the holder at the point farthest from the first surface 1141a of the base BS.

[0515] In addition, an alignment groove (not shown) may be provided on the first surface 1141a. The alignment groove (not shown) may be provided at one side of the first surface 1141a to provide an assembly position or assembly direction of the tilt guide unit 1141 during the assembly process.

[0516] In addition, the tilt guide unit 1141 may include a second protrusion PR2 extending to one side on the second surface 1141a. According to an embodiment, the second protrusion PR2 may protrude from the second surface 1141b toward the fourth shell side. There are multiple second protrusions PR2, and in an embodiment, they may include a 2-1 protrusion PR2a and a 2-2 protrusion PR2b.

[0517] The 2-1 protrusion PR2a and the 2-2 protrusion PR2b may be arranged side by side in the first direction (X-axis direction). That is, the 2-1 protrusion PR2a and the 2-2 protrusion PR2b may overlap in the first direction (X-axis direction). In addition, in an embodiment, the 2-1 protrusion PR2a and the 2-2 protrusion PR2b may be bisected by a virtual line extending in the first direction (X-axis direction).

[0518] The 2-1st protrusion PR2a and the 2-2nd protrusion PR2b may have a curvature, for example, may be hemispherical. In addition, the 2-1st protrusion PR2a and the 2-2nd protrusion PR2b may contact the second protrusion groove of the side of the fourth shell at a point spaced apart from the second surface 1141b of the base BS.

[0519] The 1-1 protrusion PR1a and the 1-2 protrusion PR1b may be disposed in an area between the 2-1 protrusion PR2a and the 2-2 protrusion PR2b. According to an embodiment, the 1-1 protrusion PR1a and the 1-2 protrusion PR1b may be disposed in the center of a separation space between the 2-1 protrusion PR2a and the 2-2 protrusion PR2b in the first direction. Due to this configuration, the first camera actuator according to the embodiment may have the same range of Y-axis tilt angles relative to the Y-axis. In other words, the tilt guide unit 1141 may provide the same range (e.g., a positive / negative range) in which the retainer can be tilted on the Y-axis with reference to the 1-1 protrusion PR1a and the 1-2 protrusion PR1b.

[0520] In addition, the 2-1 protrusion PR2a and the 2-2 protrusion PR2b may be arranged in the area between the 1-1 protrusion PR1a and the 1-2 protrusion PR1b in the second direction. According to an embodiment, the 2-1 protrusion PR2a and the 2-2 protrusion PR2b may be arranged in the center of the separation space between the 1-1 protrusion PR1a and the 1-2 protrusion PR1b in the second direction. Due to this configuration, the actuator according to the embodiment can provide the same range (e.g., positive / negative range) in which the retainer can be tilted on the X-axis relative to the X-axis. In other words, the tilting guide unit 1141 can provide the same range (e.g., positive / negative range) in which the retainer can be tilted on the X-axis with the 2-1 protrusion PR2a and the 2-2 protrusion PR2b as reference.

[0521] Specifically, the first surface 1141a may include a first outer line M1, a second outer line M2, a third outer line M3, and a fourth outer line M4. The first outer line M1 and the second outer line M2 may face each other, and the third outer line M3 and the fourth outer line M4 may face each other. In addition, the third outer line M3 and the fourth outer line M4 may be arranged between the first outer line M1 and the second outer line M2. In addition, the first outer line M1 and the second outer line M2 are perpendicular to the first direction (X-axis direction), and the third outer line M3 and the fourth outer line M4 may be perpendicular to the first direction (X-axis direction).

[0522] At this time, the first protrusion PR1 can be set on the second virtual line VL2. Here, the first virtual line VL1 is a line that divides the first outer line M1 and the second outer line M2 into two equal parts. In addition, the second virtual line VL2 is a line that divides the third outer line M3 and the fourth outer line M4 into two equal parts. Alternatively, the first virtual line VL1 and the third virtual line VL1' are lines that divide the base BS into two equal parts in the second direction (Y-axis direction). The second virtual line VL2 and the fourth virtual line VL2' are lines that divide the base BS into two equal parts in the first direction (X-axis direction). In addition, the first center point C1 can be the intersection of the first virtual line VL1 and the second virtual line VL2. Alternatively, depending on the shape of the tilt guide unit 1141, the first center point C1 can be a point corresponding to the center of gravity.

[0523] Therefore, the tilt guide unit 1141 can easily perform Y-axis tilting through the first protrusion PR1. In addition, since the tilt guide unit 1141 performs Y-axis tilting relative to the second virtual line VL2, the rotation force can be uniformly applied to the tilt guide unit 1141. Therefore, the X-axis tilting can be accurately performed, and the reliability of the device can be improved.

[0524] In addition, the 1-1 protrusion PR1a and the 1-2 protrusion PR1b may be formed symmetrically with respect to the first virtual line VL1 and the second virtual line VL2. Alternatively, the 1-1 protrusion PR1a and the 1-2 protrusion PR1b may be symmetrically arranged with respect to the first center point C1. With this structure, when Y-axis tilting is performed, the supporting force supported by the first protrusion PR1 may be equally applied to the upper side and the lower side with respect to the second virtual line VL2. Therefore, the reliability of the tilting guide unit may be improved.

[0525] In addition, the second surface 1141b may include a fifth outer line M1', a sixth outer line M2', a seventh outer line M3', and an eighth outer line M4'. The fifth outer line M1' and the sixth outer line M2' may face each other, and the seventh outer line M3' and the eighth outer line M4' may face each other. The seventh outer line M3' and the eighth outer line M4' may be arranged between the fifth outer line M1' and the sixth outer line M2'. The fifth outer line M1' and the sixth outer line M2' are perpendicular to the first direction (X-axis direction), and the seventh outer line M3' and the eighth outer line M4' may be parallel to the first direction (X-axis direction).

[0526] Furthermore, since the tilt guide unit 1141 performs X-axis tilt with respect to the third virtual line VL1', a rotation force may be uniformly applied to the tilt guide unit 1141. Therefore, the X-axis tilt may be accurately performed, and reliability of the device may be improved.

[0527] In addition, the 2-1 protrusion PR2a and the 2-2 protrusion PR2b can be symmetrically arranged on the third virtual line VL1' about the fourth virtual line VL2'. Alternatively, the 2-1 protrusion PR2a and the 2-2 protrusion PR2b can be symmetrically arranged about the second center point C1'. With this structure, when the X-axis is tilted, the supporting force supported by the second protrusion PR2 can be equally applied to the upper and lower sides of the tilt guide unit with the third virtual line VL1' as the reference. Therefore, the reliability of the tilt guide unit can be improved. Here, the third virtual line VL1' is a line that divides the fifth outer line M1' and the sixth outer line M2' into two equal parts. The fourth virtual line VL2' is a line that divides the seventh outer line M3' and the eighth outer line M4' into two equal parts. The second center point C1' can be the intersection of the third virtual line VL1' and the fourth virtual line VL2'. Alternatively, depending on the shape of the tilt guide unit 1141, the second center point C1' can be a point corresponding to the center of gravity.

[0528] However, the above configuration is an example, and the tilt guide unit 1141 may be formed in various shapes for X-axis tilt or Y-axis tilt.

[0529] In addition, the first yoke YK1 and the second yoke YK2 may have the same length in the first direction. For example, the length of the first yoke YK1 in the first direction may be equal to the length of the second yoke YK2 in the first direction. Therefore, the attraction between the retainer 1131 and the housing may be equally applied to both sides of the tilt guide unit 1141. As a result, the force applied to the tilt guide unit 1141 is uniformly generated relative to the tilt guide unit, so that the rotation based on the tilt guide unit can be accurately performed.

[0530] Fig.75 is a perspective view of a first camera actuator according to a second embodiment of the present invention, Fig.76a is from Fig.75 The view observed by B-B' in Figure 76b is a plan view of a portion of components of a first camera actuator, Figure 76c is a side view of a portion of a first camera actuator, Fig.77 is from Fig.76a The O-O' observed view in Fig.78 is from Fig.76a The view observed by P-P' in Fig.79 is from Fig.75 The view observed in C-C'.

[0531] Reference Figure 75 to Figure 79, the first coil 1152a is arranged on the first housing side 1121, and the first magnet 1151a can be arranged on the first retainer outer side surface 1131S1 of the retainer 1131. Therefore, the first coil 1152a and the first magnet 1151a can be arranged to face each other. The first magnet 1151a can overlap at least partially with the first coil 1152a in the second direction (Y-axis direction). In addition, the first magnet 1151a can be coupled to a binding yoke disposed inside the first placement groove of the first retainer outer side surface 1131S1. In addition, an adhesive member can be additionally applied inside the first placement groove. Similarly, the second magnet 1151b can be coupled to a binding yoke disposed in the second placement groove of the second retainer outer side surface 1131S2. In addition, an adhesive member can be additionally applied in the second placement groove. This can also be applied to the third magnet and the third placement groove.

[0532] In addition, the second coil 1152b can be arranged on the second housing side 1122, and the second magnet 1151b can be arranged on the second holder outer side surface 1131S2 of the holder 1131. Therefore, the second coil 1152b and the second magnet 1151b can be arranged to face each other. The second magnet 1151b can at least partially overlap with the second coil 1152b in the second direction (Y-axis direction).

[0533] In addition, the first coil 1152a and the second coil 1152b 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). With this configuration, the electromagnetic force applied to the outer surface of the holder (the first holder outer surface and the second holder outer surface) is set on a parallel axis in the second direction (Y-axis direction), so that the X-axis tilt can be performed accurately and precisely.

[0534] In addition, the second protrusions PR2a and PR2b of the tilting guide unit 1141 are disposed inside the second protrusion groove PH2 of the first housing 1120 and can contact the second protrusion groove PH2. In addition, when performing X-axis tilting, the second protrusions PR2a and PR2b can be a reference axis (or rotation axis) of the tilting. Therefore, the tilting guide unit 1141 and the mover 1130 can move left and right.

[0535] In addition, the contact point between the second protrusion PR2 and the fourth housing side 1124 and the center of the second protrusion groove PH2 may overlap in the third direction (Z-axis direction), or may be arranged on an axis parallel to the third direction. Therefore, the actuator according to the embodiment can improve the accuracy of the X-axis tilt through the second protrusion PR2.

[0536] Also, as described above, the first Hall sensor 1153a may be disposed on the outside to be electrically connected and combined with the substrate unit 1154. In addition, the number of the Hall sensors may be plural and may be disposed on the inside of the first to third coils. However, it is not limited to these positions.

[0537] In addition, the third coil 1152c can be disposed in the third housing side portion 1123, and the third magnet 1151c can be disposed on the third holder outer side surface 1131S3 of the holder 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.

[0538] As described above, the tilt guide unit 1141 may be provided on the fourth holder outer side surface 1131S4 of the holder 1131 .

[0539] Further references Figure 76b and Figure 76c In the first camera actuator according to the embodiment, the yokes YK1 and YK2 may be provided in the region between the tilt guide unit 1141 and any one of the side surface magnets. For example, the yoke may be provided in the region between the tilt guide unit 1141 and any one of the first magnet 1151a and the second magnet 1151b. As an embodiment, the third yoke 1152c and the third magnet 1152c may be provided at the lower portion of the first yoke YK1 and the second yoke YK2. In addition, the tilt guide unit 1141 may overlap with the third magnet 1151c in the optical axis or the third direction (Z-axis direction). The tilt guide unit 1141 may overlap with the third coil 1152c in the third direction, or may not overlap with the third coil 1152c in the third direction.

[0540] In addition, the third magnet 1151c and the third coil 1152c may be disposed between the first yoke YK1 and the second yoke YK2. However, as described above, the third yoke 1152c and the third magnet 1152c may be disposed at the lower portion of the first yoke YK1 and the second yoke YK2. Therefore, the first yoke YK1 and the second yoke YK2 may not overlap with the third yoke 1152c and the third magnet 1152c in the second direction.

[0541] Different from this, each of the first yoke YK1 and the second yoke YK2 may overlap each of the first magnet 1151a and the second magnet 1151b in the third direction to form a force (eg, attraction) with the first magnet 1151a and the second magnet 1151b.

[0542] Moreover, along the optical axis direction or the third direction (Z-axis direction), the first and second yokes YK1 and YK2 or the third coil (or magnet) may be disposed between the tilt guide unit 1141 and the first and second coils (or the first and second magnets).

[0543] In addition, the first protrusion of the inclined guide unit can be arranged between the first yoke YK1 and the second yoke YK2. The center of the first protrusion can be arranged on the axis in the same optical axis direction as the center of the yokes YK1 and YK2. For example, the distance between the center of the yokes YK1 and YK2 and the third coil 1152c in the first direction (X-axis direction) can be the same as the distance between the yokes YK1 and YK2 and the center of the first protrusion in the first direction (X-axis direction). Alternatively, the center of the yokes YK1 and YK2 (for example, divided into two equal parts in the first direction) and the center of the first protrusion (for example, divided into two equal parts in the first direction) can be located on the same plane YZ.

[0544] In addition, the first yoke YK1 and the second yoke YK2 do not overlap with the optical member in the optical axis direction or the third direction. For example, the virtual line connecting the first yoke and the second yoke and the optical member may overlap. However, the optical member 1132 may be disposed between the first yoke YK1 and the second yoke YK2. In addition, the optical member may be disposed 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. This may also be applied to the first coil and the second coil.

[0545] Moreover, as will be described later, by the second electromagnetic force (Y1->Y1b) between the first magnet 1151a and the first coil 1152a and the second magnet 1151b and the second coil 1152b, the mover 1130 can perform OIS implementation while rotating at a second angle θ2 in the Y-axis direction. At this time, the attraction between the yoke YK1 and the first magnet 1151a and the second magnet 1151b may work. In addition, based on the rotation direction of the mover, there may be differences in relative forces. For example, when rotating in one direction, the compound force may act on the second magnet in the direction opposite to the direction of the optical axis, and the compound force may act on the first magnet in the direction of the optical axis. In addition, when rotating in another direction, the compound force may act on the second magnet in the direction of the optical axis, and the compound force may act on the first magnet in the direction opposite to the direction of the optical axis.

[0546] Further references Fig.77 and Fig.78, in the tilting guide unit 1141, the first protrusion PR1 can be placed in the first protrusion groove PH1 of the outer side surface 1131S4 of the fourth holder. In the tilting guide unit 1141, the second protrusion PR2 can be placed in the second protrusion groove PH2 of the side portion of the fourth shell. In addition, an attraction force is generated between the first yoke YK1 and the first magnet 1151a. In addition, an attraction force is generated between the second yoke YK2 and the second magnet 1151b. The attraction force between the yoke and the magnet can be an attraction force between the holder 1131 and the first shell 1120. Therefore, the tilting guide unit 1141 between the outer side surface 1131S4 of the fourth holder and the side portion of the fourth shell can be pressed by the holder 1131 and the first shell 1120. In this way, the position of the tilting guide unit 1141 can be maintained. In other words, even if the tilting guide unit 1141 rotates, the tilting guide unit 1141 will not fall from the holder and the shell. In this way, the first magnet 1151a and the second magnet 1151b can simultaneously provide a driving force for tilting the holder 1131 in the X direction or rotating in the second direction, and an attractive force between the first yoke YK1 and the second yoke YK2. Therefore, the yoke or the magnet may not be disposed inside the tilt guide unit 1141 or adjacent to the tilt guide unit 1141. Therefore, even without an additional magnet, an attractive force for maintaining the position of the tilt guide unit can be easily provided.

[0547] As an embodiment, the yoke may be disposed adjacent to the magnet without overlapping the tilting guide unit 1141. For example, the first yoke YK1 may be disposed adjacent to the first magnet 1151a. In addition, the second yoke YK2 may be disposed adjacent to the second magnet 1151b. In addition, the first yoke YK1 and the second yoke YK2 may not overlap with the tilting guide unit 1141 along the optical axis direction (Z-axis direction).

[0548] Therefore, the first yoke YK1 and the second yoke YK2 may be disposed on the outside of the tilt guide unit 1141. In addition, the first yoke YK1 and the second yoke YK2 may be symmetrically disposed with respect to the tilt guide unit, the optical member 1132, and the holder 1131. With this configuration, the suction force generated by the first yoke YK1 and the second yoke YK2 may be uniformly applied between the holder 1131 and the first housing 1120. That is, by the first yoke YK1 and the second yoke YK2, the X-axis tilt of the holder 1131 and the optical member 1132 may be accurately achieved without tilting to one side.

[0549] In addition, the first yoke YK1 and the second yoke YK2 may be located between the tilting guide unit 1141 and the first magnet 1151a and the second magnet 1151b. For example, the first yoke YK1 may be located in a region between the tilting guide unit 1141 and the first magnet 1151a. The second yoke YK2 may be located in a region between the tilting guide unit 1141 and the second magnet 1151b.

[0550] The first yoke YK1 may be disposed to correspond to the first magnet 1151 a , and the second yoke YK2 may also be disposed to correspond to the second magnet 1151 b .

[0551] As an embodiment, the first yoke YK1 may overlap with the first magnet 1151a along the optical axis direction (Z axis direction). In addition, the first yoke YK1 may not overlap with the first coil 1152a along the optical axis direction. In other words, the first yoke YK1 may not be aligned with the first coil 1152a in the optical axis direction.

[0552] In addition, the second yoke YK2 may overlap with the second magnet 1151b along the optical axis direction (Z axis direction). In addition, the second yoke YK2 may not overlap with the second coil 1152b along the optical axis direction. In other words, the second yoke YK2 may not be aligned with the second coil 1152b in the optical axis direction.

[0553] With this configuration, the first yoke YK1 can minimize interference with the first coil 1152a and provide maximum attraction with the first magnet 1151a. In addition, the second yoke YK2 can also minimize interference with the second coil 1152b and provide maximum attraction with the second magnet 1151b.

[0554] Furthermore, the first magnet 1151a and the second magnet 1151b are symmetrically disposed inside the holder 1131, and the first yoke YK1 and the second yoke YK2 may be symmetrically disposed relative to the holder 1131. Therefore, when the tilt guide unit 1141 performs X-axis tilting, accurate driving may be achieved without tilting to one side.

[0555] In addition, the center YG1 of the first yoke YK1 and the center YG2 of the second yoke YK2 may correspond to the center MG1 of the first magnet 1151a and the center MG2 of the second magnet 1151b. For example, the center YG1 of the first yoke YK1 and the center YG2 of the second yoke YK2 may pass through the first 2-bisector VR1 in the first direction of the first yoke YK1 or the second yoke YK2. In addition, the center MG1 of the first magnet 1151a and the center MG2 of the second magnet 1151b may pass through the second 2-bisector VR2 in the first direction of the first magnet 1151a and the second magnet 1151b.

[0556] That is, the first yoke YK1 and the first magnet 1151a can be divided into two equal parts in the first direction (X-axis direction) about the first 2-bisector VR1. In addition, the second yoke YK2 and the second magnet 1151b can be divided into two equal parts in the first direction (X-axis direction) about the second 2-bisector VR2. Therefore, the suction between the first yoke YK1 and the second yoke YK2 and the first magnet 1151a and the second magnet 1151b may not affect the Y-axis tilt.

[0557] In addition, the length YL1 of the first yoke YK1 in the first direction and the length YL2 of the second yoke YK2 in the first direction may be different from or the same as the length ML1 of the first magnet 1151a in the first direction and the length ML2 of the second magnet 1151b in the first direction. As an embodiment, the length YL1 of the first yoke YK1 in the first direction and the length YL2 of the second yoke YK2 in the first direction may be different from the length ML1 of the first magnet 1151a in the first direction and the length ML2 of the second magnet 1151b in the first direction. Specifically, the length YL1 of the first yoke YK1 in the first direction and the length YL2 of the second yoke YK2 in the first direction may be less than the length ML1 of the first magnet 1151a in the first direction and the length ML2 of the second magnet 1151b in the first direction. Therefore, the rotation of the tilting guide unit 1141 and the mover 1130 can be easily performed relative to the fixed first housing.

[0558] In addition, in the first camera actuator according to the embodiment, the first magnet 1151a and the first yoke YK1 may be provided between the first coil 1152a and the optical member 1132. In addition, the first yoke YK1 and the second yoke YK2 may be provided outside the optical member 1132. Specifically, the first yoke YK1 and the second yoke YK2 may not overlap with the optical member 1132 in the optical axis direction. In other words, the first yoke YK1 and the second yoke YK2 may not be aligned with the optical member 1132 along the optical axis direction.

[0559] In addition, the second magnet 1151b and the second yoke YK2 may be disposed between the second coil 1152b and the optical member 1132. Therefore, the yoke for generating the suction force may not be disposed at the center of the mover 1130 or the center of the second protrusion groove. Therefore, even if the suction force is uneven relative to the center of the mover 1130 or the center of the second protrusion groove, the first yoke YK1 and the second yoke YK2 may be easily adjusted.

[0560] Fig.80 is a diagram showing a first driving unit of a first camera actuator according to a second embodiment of the present invention.

[0561] Reference Fig.80The first driving unit 1150 includes a driving magnet 1151 , a driving coil 1152 , a Hall sensor unit 1153 and a substrate unit 1154 .

[0562] In addition, as described above, the driving magnet 1151 may include the first magnet 1151a, the second magnet 1151b, and the third magnet 1151c providing driving force by electromagnetic force. The first magnet 1151a, the second magnet 1151b, and the third magnet 1151c may be respectively disposed on the outer side surfaces of the holder 1131.

[0563] In addition, the driving coil 1152 may include a plurality of coils. As an embodiment, the driving coil 1152 may include a first coil 1152a, a second coil 1152b, and a third coil 1152c.

[0564] The first coil 1152a may be disposed facing the first magnet 1151a. Therefore, as described above, the first coil 1152a may be disposed in the first housing hole 1121a of the first housing side portion 1121. In addition, the second coil 1152b may be disposed facing the second magnet 1151b. Therefore, as described above, the second coil 1152b may be disposed in the second housing hole 1122a of the second housing side portion 1122.

[0565] According to the embodiment, the first camera actuator can provide optimal optical performance by utilizing the electromagnetic force between the driving magnet 1151 and the driving coil 1152 to control the rotation of the actuator 1130 on the first axis (X-axis direction) or the second axis (Y-axis direction), thereby minimizing the occurrence of decent or tilt when implementing OIS.

[0566] In addition, according to an embodiment, OIS is achieved by tilting the tilt guide unit 1141 of the rotating part 1140 provided between the first shell 1120 and the mover 1130, thereby solving the size limitation of the actuator, thereby providing an ultra-thin and ultra-small camera actuator and a camera module including the same.

[0567] The substrate unit 1154 may include a first substrate side portion 1154 a , a second substrate side portion 1154 b , and a third substrate side portion 1154 c .

[0568] The first substrate side portion 1154a and the second substrate side portion 1154b may be disposed to face each other. In addition, the third substrate side portion 1154c may be located between the first substrate side portion 1154a and the second substrate side portion 1154b.

[0569] In addition, the first substrate side 1154a can be arranged between the first shell side and the shielding can, and the second substrate side 1154b can be arranged between the second shell side and the shielding can. In addition, the third substrate side 1154c can be arranged between the third shell side and the shielding can and can be the bottom surface of the substrate unit 1154.

[0570] The first substrate side portion 1154a may be coupled to and electrically connected to the first coil 1152a. In addition, the first substrate side portion 1154a may be coupled to and electrically connected to the first hall sensor 1153a.

[0571] The second substrate side 1154b may be coupled to and electrically connected to the second coil 1152b. In addition, it should be understood that the second substrate side 1154b may be coupled to and electrically connected to the first Hall sensor.

[0572] The third substrate side portion 1154c may be coupled to and electrically connected to the third coil 1152c. In addition, the third substrate side portion 1154c may be coupled to and electrically connected to the second hall sensor 1153b.

[0573] Fig.81 is a perspective view of a first camera actuator according to a second embodiment of the present invention, Fig.82 is from Fig.81 The view observed by DD′ in .

[0574] Reference Fig.81 and Fig.82 , Y-axis tilt can be performed. That is, OIS can be achieved by rotating in the first direction (X-axis direction).

[0575] As an embodiment, the third magnet 1151 c disposed at the lower portion of the holder 1131 may tilt or rotate the mover 1130 in the first direction (X-axis direction) by forming an electromagnetic force with the third coil 1152 c.

[0576] Specifically, the tilting guide unit 1141, the first housing 1120 and the mover 1130 may be combined with each other through the first yoke YK1 and the second yoke YK2. In addition, a plurality of first protrusions PR1 may be spaced apart from each other in the second direction (Y-axis direction) to support the mover 1130. In addition, the tilting guide unit 1141 may use the first protrusion PR1 protruding toward the retainer (especially the outer side surface of the fourth retainer) as a reference axis (or rotation axis) to rotate in the first direction (X-axis direction) or tilt along the Y-axis.

[0577] For example, OIS may be implemented as the mover 1130 rotates at a first angle θ1 in the X-axis direction (from X1 to X1a) by first electromagnetic forces F1A and F1B between the third magnet 1151c disposed in the third seating groove and the third coil unit 1152c disposed on the side of the third substrate.

[0578] Conversely, OIS may be implemented as the mover 1130 rotates at a first angle θ1 in a direction opposite to the X-axis direction (from X1 to X1b) by first electromagnetic forces F1A and F1B between the third magnet 1151c disposed in the third seating groove and the third coil unit 1152c disposed on the side of the third substrate.

[0579] The first angle θ1 may be ±1° to ±3°, but is not limited thereto.

[0580] Hereinafter, in the first camera actuator according to various embodiments, the electromagnetic force may move the mover by generating a force in the direction, or may move the mover in the direction even if a force is generated in another direction. That is, the direction of the electromagnetic force refers to the direction of the force generated by the magnet and the coil to move the mover. For example, the first electromagnetic forces F1A and F1B may act in a third direction or in a direction opposite to the third direction.

[0581] Fig.83 is a perspective view of a first camera actuator according to a second embodiment of the present invention, Fig.84 is from Fig.83 The view observed by EE′ in .

[0582] Reference Figure 83 to Figure 84 As the mover 1130 tilts or rotates in the Y-axis direction, OIS can be achieved.

[0583] As an embodiment, the first magnet 1151a and the second magnet 1151b provided on the holder 1131 form electromagnetic force with the first coil 1152a and the second coil 1152b respectively, so that the tilt guide unit and the mover 1130 can tilt or rotate in the second direction (Y axis).

[0584] Parts tilted in the first direction or the second direction in the first camera actuator according to the embodiment may be different from each other.

[0585] Specifically, the housing and the mover 1130 may be coupled to each other through the second yoke YK2 inside the tilt guide unit 1141. Also, as described above, a plurality of second protrusions PR2 may be spaced apart in the first direction (X-axis direction) to support the tilt guide unit and the mover 1130. In addition, the 2-1 protrusion and the 2-2 protrusion may be supported by the first housing 1120 by contacting with the first housing 1120.

[0586] In addition, the tilt guide unit 1141 may rotate or tilt the second protrusion PR2 protruding toward the housing 1120 with the first direction (X-axis direction) as a reference axis (or rotation axis).

[0587] For example, as the mover 1130 is rotated at a second angle θ2 in the Y-axis direction (from Y1 to Y1a) by the second electromagnetic forces F2A and F2B between the first magnet 1151a and the second magnet 1151b disposed in the first seating groove and the first coil unit 1152a and the second coil unit 1152b disposed on the side of the first substrate and the second substrate, OIS can be achieved. In addition, as the mover 1130 is rotated at a second angle θ2 in the Y-axis direction (from Y1 to Y1b) by the second electromagnetic forces F2A and F2B between the first magnet 1151a and the second magnet 1151b disposed in the first seating groove and the first coil unit 1152a and the second coil unit 1152b disposed on the side of the first substrate and the second substrate, OIS can be achieved. The second angle θ2 can be between ±1° and 3°. However, it is not limited thereto.

[0588] In addition, as described above, the electromagnetic force generated by the first magnet 1151a and the first coil 1152a and the second magnet 1151b and the second coil 1152b can act in a third direction or in a direction opposite to the third direction. For example, an electromagnetic force is generated in the left side of the mover 1130 in a third direction (Z-axis direction), and the electromagnetic force can act in the right side of the mover 1130 in a direction opposite to the third direction (Z-axis direction). Therefore, the mover 1130 can rotate relative to the first direction. Alternatively, it can move in the second direction.

[0589] Therefore, the second actuator according to the embodiment moves the mover 1130 in the first direction (X-axis direction) or the second direction (Y-axis direction) through the electromagnetic force between the driving magnet in the holder and the driving coil arranged in the first shell. By controlling the rotation, the occurrence of offset or tilt phenomena can be minimized when implementing OIS, and the best optical characteristics can be provided. In addition, 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).

[0590] Fig.85 is a perspective view of a second camera actuator according to a second embodiment of the present invention, Fig.86 is a perspective exploded view of a second camera actuator according to a second embodiment of the present invention, Fig.87 is from Fig.85 Cross-sectional view observed by EE′ in FIG.

[0591] ReferenceFigure 85 to Figure 87 , the second camera actuator 1200 according to the embodiment may include a lens unit 1220, a second housing 1230, a second driving unit 1250, a base unit (not shown), and a second substrate unit 1270. In addition, the second camera actuator 1200 may further include a second shielding can (not shown), an elastic portion (not shown), and an adhesive member (not shown). In addition, the second camera actuator 1200 according to the present embodiment may further include an image sensor IS.

[0592] A second shielding can (not shown) disposed in an area (e.g., the outermost side) of the second camera actuator 1200 may be disposed to surround components to be described later, the lens unit 1220, the second shell 1230, an elastic portion (not shown), a second driving unit 1250, a base unit (not shown), a second substrate unit 1270, and an image sensor IS.

[0593] Such a second shielding can (not shown) can block or reduce electromagnetic waves generated from the outside. Therefore, the malfunction of the second driving unit 1250 can be reduced.

[0594] The lens unit 1220 may be disposed in a second shielding can (not shown). The lens unit 1220 may be movable in a third direction (Z-axis direction). Therefore, the above-mentioned AF function may be performed.

[0595] Specifically, the lens unit 1220 may include a lens assembly 1221 and a bobbin 1222 .

[0596] The lens assembly 1221 may include one or more lenses. In addition, the number of lens assemblies 1221 may be multiple, but one lens assembly will be described below.

[0597] The lens assembly 1221 is coupled to the bobbin 1222 , and may be moved in a third direction (Z-axis direction) by an electromagnetic force generated from the fourth magnet 1252 a and the second magnet 1252 b coupled to the bobbin 1222 .

[0598] The wire barrel 1222 may include an open area surrounding the lens assembly 1221. In addition, the wire barrel 1222 may be coupled to the lens assembly 1221 by various methods. In addition, the wire barrel 1222 may include a groove on a side surface and may be coupled to the fourth magnet 1252a and the second magnet 1252b through the groove. An adhesive member or the like may be applied to the groove.

[0599] In addition, the bobbin 1222 may be combined with an elastic portion (not shown) at the upper end and the rear end. Therefore, the bobbin 1222 may be supported by the elastic portion (not shown) while moving in the third direction (Z-axis direction). That is, when the position of the bobbin 1222 remains unchanged, the bobbin 1222 may be maintained in the third direction (Z-axis direction). The elastic portion (not shown) may be made of a leaf spring.

[0600] The second housing 1230 may be disposed between the lens unit 1220 and a second shielding can (not shown). In addition, the second housing 1230 may be disposed to surround the lens unit 1220 .

[0601] A hole may be formed in the side of the second housing 1230. The fourth coil 1251a and the fifth coil 1251b may be disposed in the hole. The hole may be disposed to correspond to the groove of the bobbin 1222 described above.

[0602] The fourth magnet 1252a may be disposed to face the fourth coil 1251a. In addition, the second magnet 1252b may be disposed to face the fifth coil 1251b.

[0603] 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 coupled to the upper surface of the bobbin 1222. The second elastic member (not shown) may be coupled to the lower surface of the bobbin 1222. In addition, the first elastic member (not shown) and the second elastic member (not shown) may be formed as a leaf spring as described above. In addition, the first elastic member (not shown) and the second elastic member (not shown) may provide elasticity for the movement of the bobbin 1222.

[0604] The second driving unit 1250 may provide driving forces F3 and F4 to move the lens unit 1220 in the third direction (Z-axis direction). Such a second driving unit 1250 may include a driving coil 1251 and a driving magnet 1252.

[0605] The lens unit 1220 may be moved in a third direction (Z-axis direction) by an electromagnetic force formed between the driving coil 1251 and the driving magnet 1252 .

[0606] The driving coil 1251 may include a fourth coil 1251a and a fifth coil 1251b. The fourth coil 1251a and the fifth coil 1251b may be disposed inside a hole formed in a side portion of the second housing 1230. In addition, the fourth coil 1251a and the fifth coil 1251b may be electrically connected to the second substrate unit 1270. Therefore, the fourth coil 1251a and the fifth coil 1251b may receive current, etc., through the second substrate unit 1270.

[0607] The driving magnet 1252 may include a fourth magnet 1252a and a fifth magnet 1252b. The fourth magnet 1252a and the fifth magnet 1252b may be disposed in the above-mentioned groove of the bobbin 1222, and may be disposed to correspond to the fourth coil 1251a and the fifth coil 1251b.

[0608] A base unit (not shown) may be provided between the lens unit 1220 and the image sensor IS. A component such as a filter may be fixed to the base unit (not shown). In addition, the base unit (not shown) may be provided to surround the image sensor IS. With this configuration, since the image sensor IS has no foreign matter, the reliability of the device can be improved.

[0609] In addition, the second camera actuator may be a zoom actuator or an auto focus (AF) actuator. For example, the second camera actuator may support one or more lenses and perform an auto focus function or a zoom function by moving the lenses according to a predetermined control signal from the control unit.

[0610] 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.

[0611] In addition, the second camera actuator may include a plurality of lens assemblies. For example, in the second camera actuator, at least one or more 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 provided. In this regard, the above description may be applied. Therefore, the second camera actuator may perform a high magnification zoom function by a driving unit. For example, the first lens assembly (not shown) and the second lens assembly (not shown) may be moving lenses moved by a driving unit and a guide pin (not shown), and the third lens assembly (not shown) may be a fixed lens, but is not limited thereto. For example, the third lens assembly (not shown) may perform the function of a focuser that forms light at a specific position, and the first lens assembly (not shown) may perform the function of a converter that re-forms an image formed in the third lens assembly (not shown) as a focuser to another position. On the other hand, in the first lens assembly (not shown), the distance to the subject or the image distance may change significantly, so the magnification change may be large, and the first lens assembly (not shown) used as a converter may play an important role in changing the focal length or magnification of the optical system. On the other hand, the points formed by the first lens assembly (not shown) as a converter may slightly differ depending on the position. Therefore, the second lens assembly (not shown) can perform a position compensation function for the image formed by the converter. For example, the second lens assembly (not shown) can perform a compensator function for accurately imaging the image point imaged in the first lens assembly (not shown) as a converter at the actual image sensor position.

[0612] The image sensor IS may be disposed inside or outside the second camera actuator. As an embodiment, as shown, the image sensor IS may be disposed inside the second camera actuator. The image sensor IS may receive light and convert the received light into an electrical signal. In addition, the image sensor IS may include a plurality of pixels in an array form. In addition, the image sensor IS may be disposed on an optical axis.

[0616] The camera module 1000 processes image frames of still images or moving images obtained by an image sensor in a photographing mode or a video calling mode.

[0617] The processed image frame can be displayed on a prepared display unit and can be stored in a memory. A camera (not shown) can also be arranged on the front surface of the mobile terminal body.

[0618] For example, the camera module 1000 may include a first camera module 1000A and a second camera module 1000A, and the first camera module 1000A may implement OIS and AF or zoom functions.

[0619] The flash module 1530 may include a light emitting element which emits light therein. The flash module 1530 may operate through a camera operation of the mobile terminal or a user's control.

[0620] The auto focus device 1510 may include one of the packages of a surface emitting laser device as a light emitting unit.

[0621] The auto focus device 1510 may include an auto focus function using laser. The auto focus device 1510 may be mainly used in a situation where the auto focus function using the image of the camera module 1000 is degraded, for example, approaching less than 10m or in a dark environment.

[0622] The auto-focus device 1510 may include: a light emitting unit including a vertical cavity surface emitting laser (VCSEL) semiconductor device; and a light receiving unit such as a photodiode that converts light energy into electric energy.

[0625] Reference Fig.89 The vehicle 700 of the embodiment may include wheels 13FL and 13FR rotated by a power source and a prepared sensor. The sensor may be a camera sensor 2000, but is not limited thereto.

[0626] The camera 2000 may be a camera sensor to which the camera module 1000 according to the embodiment is applied. The vehicle 700 of the embodiment may obtain image information through the camera sensor 2000 that captures a front image or a peripheral image, determine a lane unrecognition situation using the image information, and may create a virtual lane when a lane is not recognized.

[0627] For example, the camera sensor 2000 may obtain a front side image by photographing the front side of the vehicle 700 , and the processor (not shown) may obtain image information by analyzing an object included in the front side image.

[0628] For example, when objects such as lanes, adjacent vehicles, driving obstacles, and indirect road markings (such as median strips, curbs, and roadside trees) are captured in an image captured by the camera sensor 2000, the processor detects these objects and includes them in the image information. At this time, the processor can obtain distance information from the object detected by the camera sensor 2000 to further supplement the image information.

[0629] The image information may be information about an object captured in the image. The camera sensor 2000 may include an image sensor and an image processing module.

[0630] The camera sensor 2000 may process a still image or a moving image obtained by an image sensor (eg, CMOS or CCD).

[0631] The image processing module may process a still image or a dynamic image acquired through an image sensor, extract necessary information, and transmit the extracted information to a processor.

[0632] At this time, the camera sensor 2000 may include a stereo camera to improve object measurement accuracy and further ensure information such as the distance between the vehicle 700 and the object, but is not limited thereto.

[0638] Hereinafter, “camera device” may be expressed by replacing the camera device with “camera”, “camera module”, “imaging device” or “photographing device”.

[0639] Fig.90 is a perspective view of a camera device 200 according to a third embodiment of the present invention, Fig.91 yes Fig.90 An exploded perspective view of the camera device 200, Fig.92 yes Fig.90 A cross-sectional view of the camera device in the AB direction.

[0640] Reference Figure 90 to Figure 92 , the camera device 200 may include a first actuator 310 , a second actuator 320 , and an image sensing unit 330 .

[0641] The second actuator 320 may move the optical member 40 to perform an optical image stabilizer (OIS) operation to perform hand shake correction, and the second actuator 320 may be expressed by being replaced with a “second driving unit” or an “OIS driving unit”.

[0642] The second actuator 320 may change the optical path. For example, the second actuator 320 may include an optical member 40 that changes the optical path. The second actuator 320 may be expressed by being replaced with an optical path changing unit.

[0643] The first actuator 310 can move the lens assemblies 312 and 313 in the optical axis direction, thereby performing an auto focus and / or zoom function, and can be expressed by replacing it with a "first drive unit" or an "AF and zoom drive unit". The first actuator 310 can be referred to as a "second actuator", and the second actuator 320 can be referred to as a "first actuator".

[0644] For example, the first actuator 310 may be disposed at a rear end of the second actuator 320 and may be combined with the second actuator 320. For example, the first actuator 310 may be disposed between the second actuator 320 and the image sensing unit 330.

[0645] The image sensing unit 330 receives and detects light passing through the optical member 40 of the second actuator 320 and the lens assemblies 311 , 312 , and 313 of the first actuator 310 , and detects the light to convert it into an electric signal.

[0646] The camera device 200 may further include a cover member 300. The cover member 300 may have a box shape including an upper plate 301 and a side plate 302 and may have an open lower portion. The cover member 300 may accommodate the first actuator 310, the second actuator 320, and the image sensing unit 330. An opening 303 or a hole exposing the incident surface of the optical member 40 may be formed in the upper plate 301 of the cover member 300.

[0647] In addition, the camera device 200 may further include a bracket (not shown) for accommodating the first actuator 310, the second actuator 320, and the image sensing unit 330. The bracket may have a hole or a through hole for accommodating the first actuator 310, the second actuator 320, and the image sensing unit 330. At least one opening may be formed in a side portion or a side surface of the bracket.

[0648] At least one protrusion 304 coupled with at least one opening of the bracket may be formed on the side plate 302 of the cover member 300. The at least one protrusion 304 may protrude from the side plate 302 in a direction perpendicular to the optical axis (eg, Y-axis direction).

[0649] The cover member 300 may be formed of a metal plate material, but is not limited thereto, and the cover member 300 may be formed of a plastic or resin material. In addition, the cover member 300 may be made of a material that blocks electromagnetic waves.

[0650] The camera device 200 may further include a protective film 24, which is disposed on the upper plate 301 of the cover member 300 and covers the opening 303 of the cover member 300. The protective film 24 may be formed of a light-transmitting material, may prevent foreign matter from entering the camera device 200, and may protect the optical member 40 from impact, etc. In addition, the camera device 200 may further include a protective tape 25, which is disposed between the protective film 24 and the upper plate 301 and attaches the protective film 24 to the upper plate 301.

[0652] Reference Figures 93 to 103b , the second actuator 320 may include an optical member 40 and a second driving unit 70. The optical member 40 may change the optical path so that light passing through the opening 303 of the cover member 300 is incident on the first actuator 310. The second driving unit 70 may rotate the optical member 40 at a preset angle in a direction (e.g., an X-axis direction or a Y-axis direction) perpendicular to the optical axis direction (e.g., a Z-axis direction).

[0653] The optical member 40 may include a reflector capable of changing the traveling direction of light. For example, the optical member 40 may be a prism that reflects light, but is not limited thereto. In another embodiment, the optical member 40 may be a reflector.

[0654] The optical member 40 may be disposed in the holder 30. The optical member 40 may change the optical path of the incident light to an optical axis parallel to the central axis (e.g., Z axis) of the lens unit to change the incident light into parallel light, which may pass through the first lens assembly 640, the second lens assembly 622, and the third lens assembly 624 to reach the image sensor 540.

[0655] Reference Fig.94 For example, the optical member 40 may include an incident surface 8A and an exit surface 8B, and reflect light incident on the incident surface 8A to exit through the exit surface 8B. For example, the optical member 40 may be a right angle prism including the incident surface 8A, the reflective surface 8C, and the exit surface 8B. For example, the internal angle between the incident surface 8A and the exit surface 8B may be a right angle.

[0656] In addition, for example, the first internal angle between the incident surface 8A and the reflection surface 8C and the second internal angle between the exit surface 8B and the reflection surface 8C may be 30 to 60 degrees. For example, each of the first internal angle and the second internal angle may be 45 degrees, but is not limited thereto. In addition, since the optical path is changed by the optical member 40, the thickness of the camera device 200 in the direction perpendicular to the incident surface 8A of the optical member 40 can be reduced, and as a result, the thickness of the mobile device or terminal 200A on which the camera device 200 is mounted can be reduced.

[0657] For example, the second actuator 320 includes a housing 50 , a holder 30 disposed inside the housing 50 , an optical member 40 disposed inside the holder 30 , and a support portion 60 disposed between the holder 30 and the housing 50 .

[0658] Reference Fig.94 and Figures 95a to 95c , the holder 30 may include a seating portion 104 on which the optical member 40 is disposed or mounted. The seating portion 104 may have a groove shape, and may include a mounting surface 104a (or a seating surface) for disposing the reflective surface 8C of the optical member 40. For example, the mounting surface 104a may be an inclined surface inclined relative to the optical axis direction.

[0659] For example, an adhesive for attaching the optical member 40 may be provided on the mounting surface 104 a of the holder 30 , and, for example, at least one groove (not shown) may be formed on the mounting surface 104 a to accommodate the adhesive.

[0660] For example, the holder 30 may include: a first opening, which exposes the incident surface 8A of the optical member 40; and a second opening, which exposes the exit surface 8B of the optical member 40. For example, the first opening may be provided on the upper side of the holder 30, and the second opening may be provided on a side surface (front outer side surface 31a) of the holder 30 facing the lens assembly (e.g., 311) of the first actuator 310. The exit surface 8B of the optical member 40 mounted on the holder 30 may be provided to face the lens assembly 311 of the first actuator 310.

[0661] Reference Fig.95a , the upper surface 18 of the retainer 30 may include: a first surface 18A; and a second surface 18B, the second surface 18B having a step with the first surface 18A in a second direction (e.g., the X-axis direction). The first surface 18A may be adjacent to or disposed adjacent to the rear outer side surface 31b of the retainer 30, and the second surface 18B may be adjacent to or disposed adjacent to the front outer side surface 31a of the retainer 30. The second surface 18B may be disposed lower than the first surface 18A. For example, the second surface 18B may be disposed closer to the lower surface 19 of the retainer 30 than the first surface 18A.

[0662] Since the second surface 18B has a step difference from the first surface 18A, when the holder 30 is tilted or rotated by a predetermined angle in the second direction (eg, X-axis direction), spatial interference between the holder 30 and the housing 50 can be prevented.

[0663] For example, at least one stopper 38 may be formed on the upper surface (e.g., the second surface 18B) of the retainer 30. The stopper 38 may be a protrusion or a projection that protrudes upward from the upper surface (e.g., the second surface 18B) of the retainer 30. For example, the stopper 38 may be formed on the upper surface of each of the first side portion and the second side portion of the retainer 30. The tilt or rotation of the retainer 30 in the second direction may be limited by the stopper 38. For example, the height of the upper surface of the stopper 38 may be lower than or equal to the height of the first surface 18A.

[0664] The holder 30 may include side portions (or outer side surfaces) 31c and 31d facing each other or arranged opposite to each other. For example, the seating portion 104 may be arranged between the two side portions 31c and 31d of the holder 30. For example, the two side portions 31c and 31d may be arranged opposite to each other or facing each other in a third direction (e.g., the Y-axis direction).

[0665] For example, the front outer side surface 31a of the retainer 30 is called the outer side surface of the first side portion of the retainer 30, the rear outer side surface 31b of the retainer 30 is called the outer side surface of the second side portion of the retainer 30, the side 31c of the retainer 30 is called the third side portion of the retainer 30, and the side 31d of the retainer 30 is called the fourth side portion 31d of the retainer 30.

[0666] For example, at least one stopper 39A may be formed on the third side portion 31c and the fourth side portion 31d of the holder 30. The stopper 39A may be a protrusion or a projection protruding from the outer surface of each of the third side portion 31c and the fourth side portion 31d of the holder 30. The tilt or rotation of the holder 30 in the third direction may be limited by the stopper 39A.

[0667] The holder 30 may include at least one protrusion 7A formed on the inner side surface of at least one of the side portions 31c and 31d. The protrusion 7A may prevent the optical member 30 from being separated from the second opening of the holder 30. For example, at least a portion of the exit surface 8B of the optical member 30 may be supported or contacted by the protrusion 7A of the holder 30.

[0668] Reference Fig.95c , the lower surface 17 of the retainer 30 may include: a first surface 17A; and a second surface 17B, the second surface 17B having a step with the first surface 17A in a second direction (e.g., the X-axis direction). The first surface 17A may be adjacent to or in contact with the front outer side surface 31a of the retainer 30, and the second surface 17B may be adjacent to or in contact with the rear outer side surface 31b of the retainer 30. The first surface 17A may be set lower than the second surface 17B. For example, the second surface 17B may be set closer to the upper surface 18 of the retainer 30 than the first surface 17A.

[0669] Since the second surface 17B of the lower surface 17 of the retainer 30 has a step difference with the first surface 17A, when the retainer 30 is tilted or rotated by a preset angle in a second direction (e.g., the X-axis direction), spatial interference between the retainer 30 and the second OIS coil 230C can be prevented.

[0670] The holder 30 may include a first seating groove 16A (see Fig.94 ); and a second placement groove 16B for setting or placing the second OIS magnet 32 ​​(see Fig.95c ).

[0671] For example, the first seating groove 16A may be formed on the outer side surface of each of the third side portion 31c and the fourth side portion 31d of the holder 30. For example, the first seating groove 16A may have a groove shape recessed from the outer side surface of each of the third side portion 31c and the fourth side portion 31d of the holder 30.

[0672] For example, the second seating groove 16B may be formed on the lower surface 17 (eg, second surface 17B) of the holder 30. For example, the second seating groove 16B may be in the form of a groove recessed from the lower surface 17 (eg, second surface 17B) of the holder 30.

[0673] Reference Fig.95b , the holder 30 may include a groove 106A formed on the outer side surface 31b (or the rear outer side surface) of the holder 30 to correspond to, face or overlap with the protrusion 57A of the housing 50. The groove 106A may be provided at the center of the outer side surface 31b of the holder 30, and may be a shape that is recessed from the outer side surface 31b. For example, at least a portion of the protrusion 57A of the housing 50 may be provided inside the groove 106A of the holder 30.

[0674] In addition, the holder 30 may include a groove 105 formed on the outer side surface 31b (or rear outer side surface) of the holder 30 to correspond to, face or overlap the protrusion 64 of the driving plate 61. For example, the groove 105 may be recessed from the outer side surface 31b of the holder 30.

[0675] For example, the holder 30 may include: a first groove 105A, which faces or overlaps with the first protrusion 64A of the drive plate 61; and a second groove 105B, which faces or overlaps with the second protrusion 64B of the drive plate 61. For example, at least a portion of the first protrusion 64A of the drive plate 61 may be disposed inside the first groove 105A of the holder 30, and at least a portion of the second protrusion 64B of the drive plate 61 may be disposed inside the second groove 105B of the holder 30. For example, the groove 106A of the holder 30 may be disposed between the first groove 105A and the second groove 105B of the holder 30.

[0676] Reference Fig.95b , the holder 30 may include a groove 36 corresponding to, facing, or overlapping the protrusion (or "front protrusion" 62) of the drive plate 61. The groove 36 may be formed on the outer side surface 31b of the holder 30, and may be a shape that is recessed from the outer side surface 31b of the holder 30. For example, the number of the grooves 36 may be the same as the number of the protrusions 62 of the drive plate 61, and may be more than one.

[0677] For example, the holder 30 may include a first groove 36A corresponding to the first protrusion 62B1 of the driving plate 61 and a second groove 36B corresponding to the second protrusion 62B2 of the driving plate 61 .

[0678] For example, the two grooves 36A and 36B of the holder 30 may be disposed spaced apart from each other in the second direction. For example, the arrangement direction of the grooves 36A and 36B may be the same as the arrangement direction of the protrusions of the driving plate 61 .

[0679] For example, the first groove 36A may include a bottom surface and a plurality of side surfaces. For example, each of the plurality of side surfaces of the first groove 36A may have the same area. In another embodiment, the area of ​​at least one of the plurality of side surfaces of the first groove 36A may be different from the area of ​​at least another of the plurality of side surfaces of the first groove 36A. For example, the bottom surface of the first groove 36A may be rectangular or elliptical, but is not limited thereto.

[0680] For example, the second groove 36B may include a bottom surface and a plurality of side surfaces. The second groove 36B may have the same shape as the first groove 36A. In another embodiment, the side surfaces of either the first groove or the second groove may be the same, and at least one of the side surfaces of the other of the first groove and the second groove may have different areas.

[0681] The second groove 36B may include a bottom surface and a plurality of side surfaces. Each of the plurality of side surfaces of the second groove 36B may have the same shape, for example, the same area.

In other embodiments, the number of side surfaces of the second groove 36B may be more than five. For example, the bottom surface of the second groove 36B may be square or circular, but not limited thereto.

[0682] A protrusion or step may be formed around the first groove 36A and the second groove 36B. The protrusion may protrude from the rear outer side surface 31b. Lubricant may be provided between the protrusions 61B1 and 61B2 and the first groove 36A and the second groove 36B. The protrusion formed around the first groove 36A and the second groove 36B may prevent the lubricant from overflowing.

[0683] The retainer 30 may include at least one stopper (not shown) formed on the rear outer side surface 31b. For example, the stopper of the retainer 30 may be in the form of a protrusion or projection protruding from the rear outer side surface 31b.

[0684] The holder 30 may include a groove 37 to accommodate or support a portion of the elastic member 63. For example, the number of the grooves 37 may be the same as the number of the elastic units 63A and 63B of the elastic member 63.

For example, the first groove 37A and the second groove 37B may be spaced apart from each other.

[0686] In another embodiment, at least one of the groove 106A or the protrusion 57A of the shell 50 may be omitted, the groove 37 may be a shape recessed from the rear outer side surface 31b of the retainer 30, and the groove 51 may be recessed from the inner side surface of the second side portion 28B of the shell 50.

[0687] For example, when the rear outer side surface 31 b is viewed from the front, the groove 37 may be provided between the two grooves 36A and 36B of the retainer 30 .

[0688] The housing 50 may be disposed inside the cover member 300. For example, an adhesive or a shielding member may be provided between the housing 50 and the cover member 300, and the housing 50 may be bonded or fixed to the cover member 300. The holder 30 may be disposed inside the housing 50. The housing 50 may accommodate the holder 30 therein, and may expose the incident surface 8A and the exit surface 8B of the optical member 40 disposed in the holder 30.

[0689] For example, refer to Fig.99a and Fig.99b The housing 50 may include a first opening 53A (or a first hole) for exposing the incident surface 8A of the optical member 40 and a second opening 53B (or a second hole) for exposing the exit surface 8B of the optical member 40 .

[0690] The housing 50 may include an upper portion 27A, a lower portion 27B, and a side portion 28 disposed between the upper portion 27A and the lower portion 27. For example, the side portion of the housing 50 may include a plurality of side portions 28A to 28D.

[0691] The upper portion 27A and the lower portion 27B of the housing 50 may face each other in the second direction (eg, the X-axis direction), or may be disposed opposite to each other. For example, the housing 50 may include a first side portion 28A, a second side portion 28B, a third side portion 28C, and a fourth side portion 28D.

[0692] 28C may be expressed as a "first side", 28D may be expressed as a "second side", 28B may be expressed as a "third side", 28D may be expressed as a "fourth side", and in another embodiment, the sides of the shell 50 may be expressed in various distinguishable forms.

[0693] For example, the first side portion 28A of the housing 50 may be disposed to face or be opposite to the lens assembly 311 of the first actuator 310. The first opening 53A may be formed in the upper portion 27A, and the second opening 53B may be formed in the first side portion 28A.

[0694] The second side portion 28B may be arranged to face the first side portion 28A in the first direction or on the opposite side of the first side portion 28A. The third side portion 28C and the fourth side portion 28D may be arranged between the first side portion 28A and the second side portion 28D, and may be arranged to face each other in a third direction (e.g., the Y-axis direction), or may be arranged on the opposite sides thereof. For example, the third side portion 28C may connect one end of the first side portion 28A with one end of the second side portion 28B, and the fourth side portion 28D may connect the other end of the first side portion 28A with the other end of the second side portion 28B.

[0695] For example, the housing 50 may include: a first hole 54A formed in the third side portion 28C to place or set the first OIS coil unit 230A; a second hole 54B formed in the fourth side portion 28D to place or set the second OIS coil unit 230B; and a third hole 54C formed in the lower portion 27B to place or set the third OIS coil unit 230C. For example, each of the first hole 54A to the third hole 54C is in the form of a through hole, but is not limited thereto, and in another embodiment, each of the first hole 54A to the third hole 54C may be in the form of a groove.

[0696] In addition, a groove 56 (or a through hole) for disposing or seating the second driver 260 may be formed in the third side portion 28C (or the fourth side portion 28D) of the housing 50. For example, the groove 56 may be formed to be spaced apart from the first hole 54A.

[0697] In another embodiment, the housing 50 may include at least one coupling protrusion (not shown) formed on at least one of the third side 28C, the fourth side 28D, and the lower portion 28b, and the circuit board 250 may include a hole for coupling with the at least one coupling protrusion.

[0698] The second side 28B of the housing 50 may include grooves 58 corresponding to, facing or overlapping the grooves (or mounting grooves 68) of the drive plate 61. The number of grooves 58 may be the same as the number of grooves 68 of the drive plate 61 or the same as the number of rolling members 65.

[0699] For example, the housing 50 may include two grooves 58A and 58B formed in the second side portion 28B spaced apart from each other. For example, the two grooves 58A and 58B of the housing 50 may be spaced apart from each other in the third direction. The description of the grooves 36A and 36B of the retainer 30 may be applied or analogically applied to the grooves 58A and 58B of the housing 50.

[0700] For example, the protrusion 57A of the housing 50 may be disposed between the two grooves 58A and 58B of the housing 50. Furthermore, the groove 51 of the housing 50 may be disposed between the two grooves 58A and 58B of the housing 50.

[0701] For example, the housing 50 may include: a groove 58A corresponding to, opposite to, or overlapping with the first groove 68A of the driving plate 61 ; and a groove 58B corresponding to, opposite to, or overlapping with the second groove 68B of the driving plate 61 .

[0702] In addition, unlike what is shown in the figures, in another embodiment, the grooves 36A and 36B of the retainer 30 can be spaced apart in a third direction (for example, the Y-axis direction), the protrusions 62B1 and 62B2 of the drive plate 61 can be spaced apart from each other in the third direction, the grooves 58A and 58B of the shell 50 can be spaced apart in the second direction (for example, the X-axis direction), and the two elastic units 65B1 and 65B2 can be spaced apart from each other in the second direction.

[0703] For example, the housing 50 may include a protrusion 57A formed on the second side portion 28B to correspond to, face, or overlap the groove 106A of the holder 30 or the opening 106 of the driving plate 61 .

[0704] For example, refer to Fig.99a The protrusion 57A may protrude from the inner side surface of the second side portion 28B of the housing 50 toward the second opening 53B of the first side portion 28A.

[0705] The housing 50 may include a groove 51 for accommodating or supporting another portion of the elastic member 63. The groove 51 may be formed in the protrusion 57A of the housing 50. The thickness of the first area of ​​the second side portion 28B of the housing 50 formed with the protrusion 57A may be greater than the thickness of the second area of ​​the second side portion 28B of the housing 50 where the protrusion 57A is not formed. In this way, by making the thickness of the first area greater than the thickness of the second area, the depth of the groove 55 for stably supporting the elastic units 63A and 63B can be ensured, and the durability of the housing 50 can be improved, and as a result, the housing 50 can be prevented from being broken or damaged due to the force applied from the elastic units 63A and 63B.

[0706] For example, the number of grooves 51 may be the same as the number of elastic units 63A and 63B of the elastic member 63. In addition, for example, the shape of the groove 51 may be a shape that easily accommodates the elastic units 63A and 63B. For example, when the groove 51 is viewed from the front, the groove 51 may have a circular shape, an elliptical shape, a polygonal shape, such as a rectangular shape.

[0707] For example, the groove 51 may be formed on a side surface of the protrusion 57A of the housing 50 facing the rear outer side surface 31b of the holder 30. For example, the groove 51 may be a shape concave to the side surface of the protrusion 57A of the housing 50.

[0708] For example, the groove 51 may include a first groove 51A corresponding to or opposite to the first elastic unit 63A and a second groove 51B corresponding to or opposite to the second elastic unit 63B. For example, the first groove 51A and the second groove 51B may be spaced apart from each other.

[0709] For example, when the inner surface of the second side portion 28B of the housing 50 is observed from the front, the protrusion 57A can be arranged between the two grooves 58A and 58B. In addition, for example, when the inner surface of the second side portion 28B of the housing 50 is observed from the front, the grooves 55A and 55B can be arranged between the two grooves 58A and 58B of the housing 50.

[0710] For example, when the inner side surface of the second side portion 28B of the housing 50 is viewed in the optical axis direction (eg, Z-axis direction), the grooves 55A and 55B of the housing 50 may overlap with the opening 106 of the driving plate 61 .

[0711] In another embodiment, the protrusion 57A of the housing 50 may be omitted, and the grooves 55A and 55B may be in a shape recessed from the inner side surface of the second side portion 28B of the housing 50 .

[0712] The housing 50 may include a guide groove 55. The guide groove 55 may be formed in the second side portion 28B of the housing 50. For example, the guide groove 55 may be formed on the inner side surface of the second side portion 28B of the housing 50. When the rolling member 65 is inserted or placed between the groove 58 of the housing 50 and the groove 68 of the drive plate 61, the guide groove 55 may be a channel for guiding the insertion or movement of the rolling member 65.

[0713] For example, the rolling member 65 may move along the guide groove 55 , and may be inserted and disposed in a space between the groove 58 of the housing 50 and the groove 68 of the driving plate 61 .

[0714] For example, the guide groove 55 may include: a first guide groove 55A provided on the groove 58A of the housing 50 ; and a second guide groove 55B provided on the groove 58B of the housing 50 .

[0715] For example, the length of the guide groove 55 in the second direction may be longer than the length of the groove 58 in the second direction. In another embodiment, the length of the guide groove 55 in the second direction may be less than or equal to the length of the groove 58 in the second direction.

[0716] The upper portion of the guide groove 55 may be formed with an opening so that the rolling member 65 can be inserted. For example, the guide groove 55 may include an opening opened from the upper surface of the housing 50. The guide groove 55 may be formed to be spaced apart from the groove 58 of the housing 50. For example, at least a portion 59 of the housing 50 may be disposed between the guide groove 55 and the groove 58.

[0717] For example, the guide groove 55 may include a chamfered shape or a stepped shape.

[0718] For example, the partition wall 59 may be disposed between the bottom surface of the guide groove 55 and the bottom surface of the groove 58. For example, the housing 50 may include: a first partition wall 59A disposed between the bottom surface of the first guide groove 55A and the bottom surface of the groove 58A; and a second partition wall 59B disposed between the bottom surface of the second guide groove 55B and the bottom surface of the groove 58B. The partition wall 59 may be used to prevent the rolling member 65 from being separated from the groove 58 of the housing 50 and the groove 68 of the drive plate 61. In other embodiments, the partition wall 59 may be omitted, and the groove 58 and the guide groove 55 may be connected to each other or communicate with each other.

[0719] For example, the thickness of the partition wall 59 or the distance between the bottom surface of the guide groove 55 and the bottom surface of the groove 58 may be smaller than the diameter of the rolling member 65. This is because, if the thickness of the partition wall 59 or the distance between the bottom surface of the guide groove 55 and the bottom surface of the groove 58 is large, it may not be easy to insert the rolling member 65 between the groove 58 of the housing 50 and the groove 68 of the drive plate 61. In another embodiment, the guide groove 55 may be connected or communicated with the groove 58 of the housing 50.

[0720] For example, the depth of the groove 58 of the housing 140 may be less than the depth of the guide groove 55. The depth of the groove 58 may be the depth of the bottom of the groove 58, and the depth of the guide groove 55A may be the depth of the bottom of the guide groove 55. In another embodiment, the depth of the groove 58 of the housing 140 may be greater than or equal to the depth of the guide groove 55.

[0721] For example, the upper surface of the protrusion 57A may be disposed closer to the bottom surface of the groove 51 of the housing 140 than the inner surface of the second side portion 28B of the housing 140. In addition, the upper surface of the protrusion 57A may be disposed closer to the inner surface of the second side portion 28B of the housing 140 than the bottom surface of the guide groove 55 of the housing 140.

[0722] Reference Fig.103a and Fig.103b , the housing 50 may include a protrusion 57B provided on the drive plate 61 and protruding from the second side portion 28B. For example, the protrusion 57B may protrude from the inner side surface of the second side portion 28B in the optical axis direction or in the first direction. For example, the protrusion 57B may be a protrusion of a portion of the upper surface or the upper end of the second side portion 28B. For example, the protrusion 57B may contact the upper end of the inner side surface of the second side portion 28B or the upper surface of the second side portion 28B.

[0723] The protrusion 57B may face or overlap the drive plate 61 in the second direction (e.g., the X-axis direction). For example, at least a portion of the protrusion 57B may face or overlap the body 61A of the drive plate 61 in the second direction (e.g., the X-axis direction). Thus, the protrusion 58B may prevent the drive plate 61 from being separated from the first opening 53A of the housing 50 due to an external impact. The protrusion 57B may be expressed as a "step", "blocking portion", "protrusion" or "separation prevention portion" instead.

[0724] Next, the support portion 60 will be described.

[0725] The support portion 60 is disposed between the retainer 30 and the housing 50, and may support the retainer 30 relative to the housing 50. The support portion 60 may include a drive plate 61 disposed between the retainer 30 and the housing 50. The support portion 60 may include a rolling member 65 disposed between the drive plate 61 and the housing 50. In addition, the support portion 60 may include an elastic member 63 connecting the retainer 30 and the housing 50.

[0726] The driving plate 61 may also be expressed by replacing the “driving plate” with “mover”, “mover plate”, “driving plate”, “plate”, “rotating plate”, “tilting plate”, “moving plate” or “supporting plate”. The driving plate 61 may be disposed between the holder 30 and the housing 50, at least a portion of the driving plate 61 may contact the holder 30, and at least another portion of the driving plate 61 may contact the housing 50.

[0727] For example, the drive plate 61 may be disposed between the rear outer side surface 31 b of the holder 30 and the second side portion 28B of the housing 50 , and may support the holder 30 relative to the housing 50 .

[0728] Reference Fig.97a and Fig.97b , the driving plate 61 may include a protrusion 62 coupled to or in contact with the holder 30. For example, the number of the protrusion 62 may be more than one. For example, the driving plate 61 may include two protrusions 62B1 and 62B2. For example, the protrusions 61B1 and 61B2 may be arranged spaced apart from each other in the second direction.

[0729] At least a portion of the protrusion 62 of the drive plate 61 may be inserted or disposed inside the groove 36 of the holder 30. For example, at least a portion of each of the protrusions 62B1 and 62B2 of the drive plate 61 may be inserted or disposed in a corresponding one of the grooves 36A and 36B of the holder 30. In another embodiment, the protrusions of the drive plate 61 may be arranged at intervals in the third direction.

[0730] The drive plate 61 may include a groove 68 in which the rolling member 65 is disposed. For example, the drive plate 61 may include grooves 68A and 68B in which the ball members 65B1 and 65B2 are disposed. For example, the grooves 68A and 68B may be spaced apart in the third direction, and in another embodiment, the grooves of the drive plate for arranging the ball members may be spaced apart in the second direction. The description of the opening 58 of the housing 50 may be applied or applied by analogy to the groove 68 of the drive plate 61.

[0731] The driving plate 61 may include an opening 106 that corresponds to, is opposite to, or overlaps with the protrusion 57A of the housing 50. The opening 106 may be disposed at a position corresponding to the protrusion 57A of the housing 50 to avoid spatial interference with the protrusion 57A. In addition, the opening 106 may be formed to avoid spatial interference between the elastic member 63 and the driving plate 61.

[0732] For example, the opening 106 of the driving plate 61 may be a through hole. For example, the opening 106 may penetrate the driving plate 61 in the first direction (Z-axis direction) or the optical axis direction.

[0733] For example, at least a portion of the opening 106 of the driving plate 61 may include a shape corresponding to the protrusion 57A of the housing 50. For example, the opening 106 may include a circular shape, an elliptical shape, a polygonal shape, and a rectangular shape.

[0734] For example, each of the length in the horizontal direction and the length in the vertical direction of the opening 106 may be greater than the diameter of the protrusion 62B1 or 62B2 of the drive plate 61. For example, the length in the lateral direction of the opening 106 may be greater than the length in the lateral direction of the protrusion 64A or 64B of the drive plate 61. In another embodiment, the length in the lateral direction of the opening 106 may be less than or equal to the length in the lateral direction of the protrusion 64A or 64B of the drive plate 61.

[0735] For example, the length of the opening 106 in the longitudinal direction may be greater than the length of the protrusion 64A or 64B of the drive plate 61 in the longitudinal direction. In another embodiment, the length of the opening 106 in the longitudinal direction may be less than or equal to the length of the protrusion 64A or 64B of the drive plate 61 in the longitudinal direction.

[0736] For example, the opening 106 may be provided between the protrusions 64A and 64B and between the protrusions 62B1 and 62B2 of the drive plate 61 .

[0737] For example, the protrusion 62 may be provided on the front surface (or first surface) of the drive plate 61, and the groove 68 may be provided on the rear surface (or second surface) of the drive plate 61. The rear surface and the front surface of the drive plate 61 may be surfaces disposed opposite to each other in the first direction or the optical axis direction. For example, the bottom surface of the drive plate 61 may be a surface facing the rear outer side surface 31b of the holder 30, and the rear surface of the drive plate 61 may be a surface facing the inner side surface of the second side portion 28B of the housing 50.

[0738] The driving plate 61 may include a protrusion 64 formed on a front surface (or a first surface) of the driving plate 61. The protrusion 64 may correspond to the groove 68 of the driving plate 61.

[0739] Reference Fig.97a , since the thickness T1 of the driving plate 61 is too thin to form the groove 68 for accommodating the rolling member 65, the groove 68 having a predetermined depth may be formed by forming a protrusion 64 on the front surface of the driving plate 61. In addition, the protrusion 64 may be used to prevent the area of ​​the driving plate 61 where the groove 68 is formed from being damaged or deformed due to impact. For example, the thickness (or protrusion height) of the protrusion 64 may be greater than the thickness of the body 61A of the driving plate 61. In another embodiment, T2 may be equal to or less than T1.

[0740] For example, the driving plate 61 may include: a body 61A; protrusions 62 ( 62B1 and 62B2 ) protruding from a front surface of the body 61A; and a groove 68 formed on a rear surface of the body 61A.

[0741] For example, each of the protrusions 62B1 and 62B2 may have a curved shape, a hemispherical shape, a dome shape, a triangular pyramid shape, a cone shape, or a polyhedron shape, but is not limited thereto.

[0742] In another embodiment, grooves (or front grooves) may be formed on the front surface of the driving plate instead of the protrusions 62B1 and 62B2, and protrusions for engaging with the front grooves of the driving plate may be formed on the holder instead of the grooves 36A and 36B.

[0743] For example, the drive plate 61 may be an injection molded product. For example, the drive plate 61 may be made of plastic, resin or ceramic material. In another embodiment, for example, the drive plate 61 may be made of metal or SUS material. In addition, the drive plate 61 may be a non-magnetic material. In another embodiment, the drive plate may be a magnetic material.

[0744] The rolling member 65 may be disposed between the rear surface of the drive plate 61 and the housing 50, and may contact the drive plate 61 and the housing 50. For example, the rolling member 65 may be a member that performs rolling motion. For example, the rolling member 65 may be a "ball", a "ball member", or a "ball bearing".

[0745] At least a portion of the rolling member 65 may be in contact with the rear surface of the driving plate 61 , and at least another portion of the rolling member 65 may be in contact with the inner side surface of the second side portion 28B of the housing 50 .

[0746] For example, at least a portion of the rolling member 65 may be inserted or disposed inside the groove 68 of the driving plate 61 , and at least another portion of the rolling member 65 may be inserted or disposed inside the groove 58 of the housing 50 .

[0747] Compared with the protrusions 62B1 and 62B2 of the driving plate 61, since the rolling member 65 performs a rolling motion, the friction force can be relatively reduced, so that the suppression ratio can be improved and the current consumption can be reduced, thereby improving the OIS driving performance. For example, the degree of performance of the OIS feedback control can be measured by the suppression ratio. For example, the suppression ratio can be defined as the logarithmic value (20log(Y)) of the ratio (Y=OUTPUT / INPUT) of the output signal (e.g., OUTPUT) of the OIS position sensor 240 to the input signal (e.g., INPUT) applied to the OIS coil 230.

[0748] One end of the elastic member 63 may be coupled to the holder 30, and the other end of the elastic member 63 may be coupled to the housing 50. For example, one end of the elastic member 63 may be coupled to the protrusion 57A of the housing 50, and the other end of the elastic member 63 may be coupled to the second side portion 28B of the holder 30.

[0749] For example, one end of the elastic member 63 may be inserted or disposed inside the groove 51 of the housing 50, and may be coupled to or fixed to the groove 51 of the housing 50. The other end of the elastic member 63 may be inserted or disposed inside the groove 37 of the holder 30, and may be coupled to the groove 37 of the holder 30. One end of the elastic member 63 may be coupled to the groove 51 of the housing 50 by an adhesive, and the other end of the elastic member 63 may be coupled to the groove 37 of the holder 30.

[0750] The elastic member 63 may be a pulling member that pulls the holder 30 and the housing 50 toward each other. For example, the holder 30 may be pressed to the housing 50 by the pulling force of the elastic member 63, so that the holder 30 may be supported.

[0751] The elastic member 63 may include at least one elastic unit 63A or 63B. For example, the number of elastic units may be one or more. For example, the elastic member 63 may include two elastic units 63A and 63B spaced apart from each other in the third direction. For example, the number of elastic units spaced apart from each other in the third direction may be two or more.

[0752] In another embodiment, the elastic member 63 may include two elastic units spaced apart from each other in the second direction. For example, the number of elastic units spaced apart from each other in the second direction may be more than two. In another embodiment, the elastic member may include only one elastic unit.

[0753] For example, the elastic units 63A and 63B may be springs, coil springs, suspension wires, or leaf springs. For example, the elastic units 63A and 63B may be made of metal.

[0754] Reference Fig.98a , Fig.98b and Fig.100b , at least a portion of the protrusion 57A of the housing 50 may be inserted into or disposed inside the opening 106 of the drive plate 61 .

[0755] The elastic member 63 may pass through the opening 106 of the driving plate 61. For example, at least a portion of the elastic member 63 in the second direction may overlap the driving plate 61. For example, the elastic units 63A and 63B may pass through the opening 106 of the driving plate 61 or avoid the body 61A of the driving plate 61.

[0756] For example, when the driving plate 61 is viewed from the front, the elastic member 63 may be disposed inside the outer peripheral surface of the driving plate 61. In addition, when the driving plate 61 is viewed from the front, the elastic member 63 may overlap with the opening 106 of the driving plate 61.

[0757] Next, the second driving unit 70 will be described.

[0758] The second driving unit 70 may tilt the holder 30 in the second direction or the third direction, or rotate it by a preset angle.

[0759] The second driving unit 70 may include an OIS magnet 31 and an OIS coil 230. The OIS magnet may be expressed by replacing the OIS magnet with "magnet" or "magnet unit", and the OIS coil may be expressed by replacing the OIS coil with "coil body", "coil" or "coil unit". In addition, the second driving unit 70 may include an OIS position sensor unit 240 and a first substrate unit 250.

[0760] The OIS magnet 31 may be disposed on the holder 30 . For example, the OIS magnet 31 may include first OIS magnets 31A and 31B and a second OIS magnet 32 ​​.

[0761] For example, the first OIS magnet may include: a first magnet unit 31A disposed on the third side 31c of the holder 30; and a second magnet unit 31B disposed on the fourth side 31d of the holder 30. For example, the first magnet unit 31A may face or overlap the second magnet unit 31B in the third direction.

That is, the first electromagnetic force may be generated by the interaction between the first magnet unit 31A and the first OIS coil unit 230A and the interaction between the second magnet unit 31B and the second OIS coil unit 230B.

[0773] For example, the OIS moving unit (e.g., the holder 30) can be tilted relative to the vertical axis 501 (e.g., the X-axis) by the first electromagnetic forces F21, F22, F31, and F32. Alternatively, for example, the OIS moving unit (e.g., the holder 30) can be rotated by a predetermined angle using the vertical axis 501 (e.g., the X-axis) as a rotation axis by the first electromagnetic forces F21, F22, F31, and F32.

[0776] The OIS moving unit can be tilted relative to the horizontal axis 502 (e.g., the X-axis) by the second electromagnetic forces F1 and F2. Alternatively, the OIS moving unit can be rotated by a predetermined angle with the horizontal axis 502 (e.g., the X-axis) as the rotation axis by the second electromagnetic forces F1 and F2. For example, the horizontal axis 502 can be a straight line passing through a rolling member (e.g., ball members 65B1 and 65B2). For example, the horizontal axis 502 can be a straight line passing through the center of the drive plate 61 and parallel to the Y-axis. For example, the horizontal axis 502 can be described as a "second rotation axis". The horizontal axis 502 and the vertical axis 501 can be perpendicular to each other.
