Description

Camera actuator and camera module including the same

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

[0002] A camera is a device that captures images or videos of a subject, and is installed in portable devices, drones, vehicles, etc. Camera modules may have an image stabilization (IS) function that compensates for or prevents image shaking caused by the user's movements to improve image quality, an auto focusing (AF) function that automatically adjusts the distance between the image sensor and the lens to align the focal length of the lens, and a zooming function that increases or decreases the magnification of a distant subject and captures it using a zoom lens.

[0003] However, miniaturized camera modules present a problem: optical performance deteriorates due to decentering and tilt. Furthermore, there is a growing demand for improved reliability, including protection against ingress of contaminants into circuit elements.

[0004] The technical problem to be solved by the present invention is to provide a camera actuator and camera device with improved optical performance by combining one housing including a lens assembly that moves along an optical axis and another housing having a fixed lens.

[0005] In order to solve the above technical problem, a camera module according to an embodiment of the present invention includes a first housing including a fixed lens; a second housing coupled with the first housing; a shield can disposed on the second housing; a lens assembly disposed within the second housing; a ball disposed between the lens assembly and the second housing; and a coil and a driving magnet for moving the lens assembly in the optical axis direction, wherein the shield can includes an upper plate and a side plate extending from the upper plate, and an inner surface of the upper plate of the shield can includes a guide portion protruding in the direction of the lens assembly, and the lens assembly includes a lens holder in which a lens is disposed and a magnet holder in which the driving magnet is disposed, and an outer surface of the lens holder may be formed in a shape in which a direction toward the upper plate of the shield can is open.

[0006] The guide portion of the above shield can can be formed to extend in the optical axis direction.

[0007] The guide portion of the shield can may be placed between the lens holder and the magnet holder.

[0008] The inner surface of the top plate of the above shield can may be matte-treated and have a black coating formed.

[0009] The shield can may include a plate placed on the opposite side of the top plate.

[0010] The inner surface of the above plate includes a guide portion that protrudes in the direction of the lens assembly, and the inner surface of the above plate may be matte-treated and have a black coating formed thereon.

[0011] The lens holder includes an opening surface connecting an open area among the outer surfaces of the lens holder, and a light-blocking member may be arranged on the opening surface of the lens holder.

[0012] The lens disposed in the lens holder may include a cut portion having a flat outer surface and an arc portion having a curved outer surface, and the cut portion of the lens may be disposed toward the open area of ​​the lens holder.

[0013] A substrate is included that is coupled to the outer surface of the second housing, and the coil is disposed on the substrate and can be electrically connected to the substrate.

[0014] The light-blocking member disposed on the opening surface of the lens holder may be disposed lower than the upper surface of the second housing.

[0015] According to an embodiment of the present invention, a camera actuator and camera device having improved optical performance are implemented by coupling one housing including a lens assembly moving along an optical axis and another housing having a fixed lens.

[0016] Additionally, a miniaturized camera module can be implemented by reducing the thickness in the direction perpendicular to the optical axis of the camera actuator.

[0017] Additionally, a light-blocking member can be placed on the inner surface of the shield can and camera actuator to prevent lens flare and ghosting defects.

[0018] In addition, a camera actuator and camera device with improved reliability of elements in optical alignment can be implemented.

[0019] In addition, it is possible to implement a camera actuator and camera device with improved reliability by protecting circuit elements, etc. from the inflow of foreign substances.

[0020] In addition, a camera actuator and camera device that minimize decentering and tilt can be implemented by adding a guide portion protruding toward the actuator to the shield can and plate portion.

[0021] The technical problem to be solved by the present invention is to implement a camera actuator applicable to ultra-slim, ultra-small, and high-resolution cameras.

[0047]

[0048] A camera module (1000) according to the present embodiment may include a first housing (1100), a second housing (1200), a lens unit (100), a first lens assembly (200), and a second lens assembly (300). The camera module (1000) may include a stopper (ST1, ST2), a yoke (YK), a shield can (1210), an elastic member (not shown), and a joining member (not shown).

[0049] The shield can (1210) may be positioned in a certain area (e.g., the outermost area) of the camera module (1000) and may be positioned to surround the components described below. The shield can (1210) may block or reduce electromagnetic waves generated from the outside. This may reduce malfunctions in the first lens assembly (200) and the second lens assembly (300).

[0050] The shield can (1210) may include a top plate and two side plates extending in both directions from the top plate. The inner surface of the shield can (1210) may be matte-finished and black-coated. The inner surface of the top plate of the shield can (1210) may be matte-finished and black-coated. This may prevent stray light from entering the lens, and may prevent lens flare and ghosting defects.

[0051] The camera module (1000) may be a separate component from the image sensor and base member described below, or may include the same. Hereinafter, a main board or circuit board separate from the camera module (1000) is described as including the image sensor and base member.

[0052] The lens unit (101 to 104, hereinafter 100) may be positioned within the shield can (1210). The lens unit (100) may move along the Z-axis direction or the optical axis direction. Accordingly, the AF function and the zoom function may be performed. The lens unit (100) may be positioned within the first housing (1100) and the second housing (1200). Accordingly, at least a portion of the lens unit (100) may move along the optical axis direction or the Z-axis direction within the first housing (1100) and the second housing (1200).

[0053]

[0054] The lens unit (100) may include first to third lens groups (101 to 103) and a rear optical unit (104).

[0055] The first to third lens groups (101 to 103) may include at least one lens. The first lens group (101), the second lens group (102), and the third lens group (103) may be sequentially arranged along the optical axis direction. The rear optical unit (104) may be arranged at the rear of the third lens group (103). The rear optical unit (104) may include a lens such as glass.

[0056] The first lens group (101) can be fixed by being combined with the first housing (1100). The first lens group (101) may not move along the optical axis direction. The second lens group (102) can move in the optical axis direction by being combined with the first lens assembly (200). Magnification adjustment can be performed by the movement of the first lens assembly (200) and the second lens group (102). The third lens group (103) can move in the optical axis direction by being combined with the second lens assembly (300). Focus adjustment or auto-focusing can be performed by the movement of the third lens group (103). However, the number of lens groups is not limited, and additional lens groups can be further arranged.

[0057] The camera module (1000) may include a first housing (1100) and a second housing (1200). The first housing (1100) may be coupled with a first lens group (101). The first housing (1100) may be positioned in front of the second housing (1200). The second housing (1200) may be positioned at the rear end of the first housing (1100). The second to third lens groups (102, 103) and the rear optical unit (104) may be mounted inside the second housing (1200).

[0058] The first housing (1100) of the camera module (1000) may include a fixed lens. The second housing (1200) may be arranged parallel to the first housing (1100) along the optical axis direction or the Z-axis direction. A movable assembly that moves along the optical axis direction may be arranged in the second housing (1200), but a lens that does not move along the optical axis direction, i.e., is fixed, may be arranged in the first housing (1100). The first housing (1100) and the second housing (1200) may be coupled to each other by a coupling member arranged between the first housing (1100) and the second housing (1200).

[0059] The first housing (1100) may include a holder portion (HP) and a wing portion (WP) extending outwardly from the holder portion (HP). The wing portion (WP) may be arranged to surround a portion of the outer surface of the holder portion (HP). The holder portion (HP) and the wing portion (WP) may have an integral or separate structure. The length of the holder portion (HP) in the X-axis direction or the Y-axis direction may be smaller than the length of the wing portion (WP) in the X-axis direction or the Y-axis direction.

[0060] The holder part (HP) may include a first holder part (HP1) arranged above the wing part (WP) and a second holder part (HP2) arranged below the wing part (WP). The first holder part (HP1), the wing part (WP), and the second holder part (HP2) may be sequentially arranged along the optical axis direction. The length of the first holder part (HP1) in the optical axis direction may be shorter than the length of the second holder part (HP2) in the optical axis direction. By this configuration, the bonding force between the first housing (1100) and the second housing (1200) can be improved, and optical alignment can be easily performed for the tilt of the first housing (1100). Accordingly, the resolution of the camera module can be improved.

[0061] The wing portion (WP) may include one side and the other side. The one side and the other side of the wing portion (WP) may be sequentially arranged in the direction of the optical axis. The other side of the wing portion (WP) may be arranged to face the inner surface of the second housing (1200). The other side of the wing portion (WP) may be spaced apart from the second housing (1200). At least a portion of the other side of the wing portion (WP) may be spaced apart from the second housing (1200).

[0062] A first stopper portion (ST1a, ST1b) may be arranged on the wing portion (WP). A first-first stopper (ST1a) and a first-second stopper (ST1b) may be arranged symmetrically with respect to the optical axis direction on the other surface of the wing portion (WP). The first-first stopper (ST1a) may be arranged to face the first magnet holder (220) of the first lens assembly (200). The first-second stopper (ST1b) may be arranged to face the second magnet holder (320) of the second lens assembly (300). The first stopper portions (ST1a, ST1b) may alleviate contact and impact with the first housing (1100) when the first lens assembly (200) and the second lens assembly (300) move in the optical axis direction.

[0063] The second housing (1200) may include a side groove adjacent to the first housing (1100). This prevents contact with the second housing (1200) even when the first housing (1100) is tilted relative to the optical axis for optical alignment. This facilitates securing a range of movement for optical axis alignment and other purposes, and improves the reliability of the camera module (1000).

[0064]

[0065] The first lens assembly (200) and the second lens assembly (300) may each be mounted on the inside of the second housing (1200).

In the second lens assembly (300), the second magnet holder (320) including the recess (RS) in which the ball (B) is placed may be positioned to face the second side. The first lens assembly (200) and the second lens assembly (300) may be positioned to overlap in the optical axis direction. The first lens assembly (200) and the second lens assembly (300) can be arranged to overlap in the Y-axis direction perpendicular to the optical axis direction.

[0066] The first lens assembly (200) and the second lens assembly (300) can be spaced apart from each other in the optical axis direction (Z-axis direction). The first lens assembly (200) and the second lens assembly (300) can move along the optical axis direction (Z-axis direction) by a driving unit (driving magnet, coil). For example, an auto focus or zoom function can be performed by the movement of the first lens assembly (200) and the second lens assembly (300).

[0067] The movable assembly may be coupled to elastic members (not shown) at the top and rear ends. Accordingly, the movable assembly may be supported by the elastic members (not shown) while moving in the Z-axis direction. That is, the position of the movable assembly may be maintained in the Z-axis direction. The elastic members (not shown) may be formed of various elastic elements, such as a plate spring.

[0068] The first lens assembly (200) may include a first lens holder (210) that holds and combines a second lens group (102).

The first light-shielding member (201) may prevent stray light from entering through the cut portion of the second lens group (102). The first light-shielding member (201) may be a matte-treated black member. The first shading member (201) can be formed to a thickness thinner than the thickness of the outer surface of the first lens holder (210). Through this, the length of the camera module in the x-axis direction can be reduced, thereby miniaturizing the camera module.

[0072] The first lens assembly (200) may include a first magnet holder (220) arranged on the outside of the first lens holder (210). A first driving magnet (401) may be arranged in the first magnet holder (220).

[0076] The third lens group (103) may have a die-cut portion formed. When viewed from the optical axis direction, the optical portion of the lens is generally formed in a circular shape, but the flange portion has a 'D' shape with a portion removed. The portion having the 'D' shape is referred to as a die-cut portion. The meaning of 'cut' in the die-cut portion may not be limited to cutting or incising.

The second shading member (301) can be formed to a thickness thinner than the thickness of the outer surface of the second lens holder (310). Through this, the length of the camera module in the x-axis direction can be reduced, thereby miniaturizing the camera module.

A second substrate (504) may be arranged on the outer surface of the second side (1201a). A protrusion (1203a, 1203b) may be formed on the outer surface of the second side (1201a). At least one of the second substrate (504) and the second yoke (YK2) may be inserted into the protrusion (1203a, 1203b) of the second side (1201a). The second substrate (504) and the second yoke (YK2) may include holes into which protrusions (1203a, 1203b) are inserted in areas corresponding to the protrusions (1203a, 1203b). The protrusions (1203a, 1203b) of the second side (1201a) may be formed spaced apart from each other based on the second hole (1202a).

[0086] The second coil (502) can be electrically connected to the second substrate (504). The second coil (502) can receive current or the like through the second substrate (504). The second position sensor (503) can be placed inside the second coil (502) having a ring shape. The second position sensor (503) can be electrically connected to the second substrate (504). The second position sensor (503) can sense the change in magnetic flux of the second driving magnet (501) so that position sensing can be performed between the second driving magnet (501) and the second position sensor (503).

[0087] The yoke (YK) may be arranged on the outside of the second housing (1200). The yoke (YK) may be arranged on the outside of the first and second coils (402, 502). The yoke (YK) may include a first yoke (YK1) and a second yoke (YK2). The first yoke (YK1) and the second yoke (YK2) may be arranged to face each other. The first yoke (YK1) and the second yoke (YK2) may be positioned to correspond to each other based on the optical axis.

[0088] The first yoke (YK1) may be positioned adjacent to the first coil (402). The second yoke (YK2) may be positioned adjacent to the second coil (502). The first coil (402) and the second coil (502) may be positioned inside the first yoke (YK1) and the second yoke (YK2). The first yoke (YK1), the first coil (402), the second coil (502), and the second yoke (YK2) may be sequentially arranged in one direction (e.g., the second direction). The first yoke (YK1) may form an attractive force with the first driving magnet (401). The second yoke (YK2) may form an attractive force with the second driving magnet (501). Accordingly, the posture of the first lens assembly (200) and the second lens assembly (300) can be maintained.

[0089] The first yoke (YK1) and the second yoke (YK2) may have varying thicknesses in some areas. By this configuration, it is possible to suppress the magnetic force generated from the first and second drive magnets (401, 501) or the first and second coils (402, 502) from affecting other magnets and coils. The first yoke (YK1) can suppress the magnetic force generated by the first drive magnet (401) from being applied to the second drive magnet (501) and the second coil (502).

[0090] The inner surface of the first side of the second housing (1200) may include first and second guide grooves (GG1a, GG1b). The first and second guide grooves (GG1a, GG1b) may be arranged symmetrically above and below the side hole of the second housing (1200). The first and second guide grooves (GG1a, GG1b) may face the recess of the first lens assembly (200). The first and second guide grooves (GG1a, GG1b) may be arranged to be spaced apart from each other in the X-axis direction. A first driving magnet (401) and a first coil (402) may be arranged between the first guide groove (GG1a) and the second guide groove (GG1b). The first and second guide grooves (GG1a, GG1b) may be grooves extending in the Z-axis direction. The first and second guide grooves (GG1a, GG1b) may have different shapes. The first guide groove (GG1a) may be a groove with an inclined side, and the second guide groove (GG1b) may be a groove with a side perpendicular to the bottom surface.

[0091] Third and fourth guide grooves (GG2a, GG2b) may be positioned on the inner surface of the second side of the second housing (1200). The third and fourth guide grooves (GG2a, GG2b) may be arranged symmetrically above and below the side hole of the second housing (1200). The third and fourth guide grooves (GG2a, GG2b) may face the recesses (RS1, RS2) of the second lens assembly (300). The third and fourth guide grooves (GG2a, GG2b) may be arranged to be spaced apart from each other in the X-axis direction. A second driving magnet (501) and a second coil (502) may be arranged between the third guide groove (GG2a) and the fourth guide groove (GG2b). The third and fourth guide grooves (GG2a, GG2b) may be grooves extending in the Z-axis direction. The third and fourth guide grooves (GG2a, GG2b) may have different shapes. The third guide groove (GG2a) may be a groove with a side surface perpendicular to the upper surface, and the fourth guide groove (GG2b) may be a groove with a side surface inclined.

[0092] The second housing (1200) may include a first region connecting the first side (1201b) and the second side (1201a), and a second region opposite the first region. Here, the first region may refer to a region adjacent to the shield can (1210) within the internal space of the second housing (1200). The second region may refer to a region adjacent to the plate (1220) within the internal space of the second housing (1200).

[0093] The first region of the second housing (1200) may be surrounded by the upper plate of the shield can (1210). The inner surface of the upper plate of the shield can (1210) may be formed with guide portions (1211a, 1211b) that protrude inwardly. The guide portions (1211a, 1211b) may be formed to protrude from the inner surface of the upper plate of the shield can (1210) toward the second region of the housing (1200). The guide portions (1211a, 1211b) may protrude (or extend) toward the first lens assembly (200) and the second lens assembly (300). The guide portions (1211a, 1211b) may be formed to extend along the z-axis direction. The guide portion (1211a, 1211b) may include a first guide portion (1211a) and a second guide portion (1211b) that are spaced apart from each other.

[0094] The first guide part (1211a) may be arranged between the first lens holder (210) and the first magnet holder (220). The first guide part (1211a) may be arranged between the first magnet holder (220) and the second lens holder (310). The second guide part (1211b) may be arranged between the second lens holder (310) and the second magnet holder (320). The second guide part (1211b) may be arranged between the second magnet holder (320) and the first lens holder (210).

[0095] The shape change of the guide grooves (GG1a, GG1b, GG2a, GG2b) can be reduced through the guide parts (1211a, 1211b). The flatness of the adjacent guide grooves (GG1a, GG1b, GG2a, GG2b) can be maintained by improving the rigidity, etc. through the guide parts (1211a, 1211b). When the first lens assembly (200) and the second lens assembly (300) move within the second housing (1200), the guide parts (1211a, 1211b) can provide further improved straightness. Through this, the camera module (1000) can minimize the occurrence of decenter or tilt phenomena and provide the best optical characteristics.

[0096] The guide portions (1211a, 1211b) may be positioned between the first guide groove (GG1a) and the third guide groove (GG2a). The first guide portion (1211a) may be formed closer to the first guide groove (GG1a) than to the third guide groove (GG2a). The second guide portion (1211b) may be formed closer to the third guide groove (GG2a) than to the first guide groove (GG1a). The guide portions (1211a, 1211b) may overlap the first guide groove (GG1a) and the third guide groove (GG2a) in the Y-axis direction.

[0097] A plate (1220) may be placed in the second region of the second housing (1200). The second region of the second housing (1200) may be surrounded by the plate (1220). The inner surface of the plate (1220) may be matte-treated and black-coated. This may prevent stray light from entering the lens and prevent a flare phenomenon. A guide portion protruding inward may be formed on the inner surface of the plate (1220). The guide portion of the plate (1220) may be formed symmetrically with the guide portions (1211a, 1211b) of the shield can (1210).

[0098] The thickness of the plate (1220) may be formed to be smaller than the thickness of the second housing (1200). The plate (1220) may be insert-molded into the second housing (1200). The plate (1220) may include protrusions (1221: 1221a, 1221b, 1221c, 1221d) that protrude in the periphery area. When the plate (1220) is insert-molded into the second housing (1200), the bonding strength between the plate (1220) and the second housing (1200) may be increased through the protrusions (1221) of the plate (1220).

[0099] The camera module (1000) according to the present embodiment can reduce the thickness of the camera module (1000) in the x-axis direction by forming the second housing (1200) and the first lens holder (200) and the second lens holder (300) in an open shape in the x-axis direction. In addition, a light-blocking member can be placed in an area where reflection on the optical path may occur within the camera module (1000) or a matte-processed and black-coated area can be used to prevent the inflow of stray light and prevent the flare phenomenon of the lens.

[0100] Referring to FIG. 11, the length from the plate (1220) in the x-axis direction to the most sunken area in the direction perpendicular to the optical axis in the first guide groove (GG1a) may be shorter than the length from the plate (1220) to the first shading member (201) in the x-axis direction. The length from the plate (1220) in the x-axis direction to the most sunken area in the direction perpendicular to the optical axis in the first guide groove (GG1a) may be shorter than the length from the plate (1220) to the second shading member (301) in the x-axis direction. The length from the plate (1220) to the first shading member (201) in the x-axis direction may be shorter than the length from the plate (1220) to the top of the second housing (1200) in the x-axis direction. The length from the plate (1220) to the second shading member (301) in the x-axis direction may be shorter than the length from the plate (1220) to the top of the second housing (1200) in the x-axis direction. The length from the plate (1220) to the first shading member (201) in the x-axis direction may be shorter than the length from the plate (1220) to the top plate of the shield can (1210) in the x-axis direction. The length from the plate (1220) to the second shading member (301) in the x-axis direction may be shorter than the length from the plate (1220) to the top plate of the shield can (1210) in the x-axis direction.

[0101] Through this, the camera module (1000) according to the present embodiment can minimize interference and smoothly operate each component placed within the camera module (1000) while reducing the length in the x-axis direction.

[0102]

[0103] The second stopper portion (ST2a, ST2b) may be arranged on the lower surface (1201c) of the second housing (1200). The first housing (1100) may be coupled to the upper end of the second housing (1200), and the lower surface of the second housing (1200) may be arranged on the opposite side from the first housing (1100). The first stopper portion (ST1a, ST1b) and the second stopper portion (ST2a, ST2b) may be arranged sequentially along the optical axis direction. The first stopper portion (ST1a, ST1b) and the second stopper portion (ST2a, ST2b) may be arranged on the movement path of the first lens assembly (200) and the second lens assembly (300).

[0104] The second stopper portion (ST2a, ST2b) may be arranged such that the second-first stopper (ST2a) and the second-second stopper (ST2b) are symmetrically arranged with respect to the optical axis direction on the lower surface (1201c) of the second housing (1200). The second-first stopper (ST2a) may be arranged to face the first magnet holder (220) of the first lens assembly (200). The second-first stopper (ST2a) may be arranged to overlap the first-first stopper (ST1a) in the optical axis direction. The second-second stopper (ST2b) may be arranged to face the second magnet holder (320) of the second lens assembly (300). The second-second stopper (ST2b) may be arranged to overlap the first-second stopper (ST1b) in the optical axis direction. The second stopper portion (ST2a, ST2b) can alleviate contact and impact with the second housing (1200) when the first lens assembly (200) and the second lens assembly (300) move in the optical axis direction.

[0105] The distance in the optical axis direction between the first-first stopper (ST1a) and the second-first stopper (ST2a) may be smaller than the distance in the optical axis direction between the first-second stopper (ST1b) and the second-second stopper (ST2b). This is a configuration that reflects the fact that the movable distance (stroke) of the first lens assembly (200) is smaller than the movable distance (stroke) of the second lens assembly (300).

[0106] As the first lens assembly (200) moves, the camera actuator can perform zooming. As the second lens assembly (300) moves, the camera actuator can perform autofocusing (AF). Reflecting this, the movement distance for zooming may be smaller than the movement distance (or stroke) for autofocusing.

[0107] For this movement distance or stroke difference, the first-first stopper (ST1a) and the first-second stopper (ST1b) may be arranged to be at least partially misaligned in the second direction (Y-axis direction). The second-first stopper (ST2a) and the second-second stopper (ST2b) may be arranged to be at least partially misaligned in the second direction (Y-axis direction).

[0108]

[0109] The first driving magnet (401) may be provided in the first lens assembly (200) by a vertical magnetization method. The N pole and the S pole of the first driving magnet (401) may both be positioned to face the first coil (402). Accordingly, the N pole and the S pole of the first driving magnet (401) may be respectively positioned to correspond to a region in which current flows in the X-axis direction or the opposite direction thereof in the first coil (402).

[0110] When a magnetic force is applied in the opposite direction of the Y-axis from the N pole of the first driving magnet (401), and a current (DE1) flows in the opposite direction of the X-axis from the first coil (402) corresponding to the N pole, an electromagnetic force (DEM1) can act in the Z-axis direction according to the interaction of electromagnetic forces (e.g., Fleming's left-hand rule). When a magnetic force is applied in the second direction (Y-axis direction) from the S pole of the first driving magnet (401), and a current (DE1) flows in the X-axis direction from the first coil (402) corresponding to the S pole, an electromagnetic force (DEM1) can act in the Z-axis direction according to the interaction of electromagnetic forces.

[0111] Since the first coil (402) is fixed to the side of the second housing (1200), the first lens assembly (200) in which the first driving magnet (401) is arranged can move in the opposite direction of the Z-axis by the electromagnetic force (DEM1) according to the current direction. That is, the first driving magnet (401) can move in the opposite direction of the electromagnetic force applied to the first coil (402). In addition, the direction of the electromagnetic force can be changed depending on the current of the coil and the magnetic force of the magnet.

[0112] An electromagnetic force (DEM1) is generated between the first driving magnet (401) and the first coil (402), so that the first lens assembly (200) can move along the first and second guide grooves (GG1a, GG1b) located on the inner surface of the second housing (1200) through the ball (B) in the direction of the optical axis. Accordingly, when the first lens assembly (200) moves in the direction of the optical axis, the first and second guide grooves (GG1a, GG1b) can act as guide rails to prevent tilting of the first lens assembly (200) and guide stroke movement.

[0113] The lengths of the first and second guide grooves (GG1a, GG1b) in the optical axis direction can be set according to the stroke length of the first lens assembly (200) in the optical axis direction. The maximum stroke length of the first lens assembly (200) can be the distance from the first-first stopper (ST1a) to the second-first stopper (ST2a) in the optical axis direction. The maximum stroke length of the first lens assembly (200) can be smaller than the distance from the first-first stopper (ST1a) to the second-first stopper (ST2a) in the optical axis direction.

[0114] The recess (RS) formed in the first magnet holder (220) can have a preset length in the optical axis direction (z-axis direction). The ball (B) can be seated in the recess (RS) of the first magnet holder (220). The distance that the ball (B) moves in the optical axis direction within the recess can be adjusted. The recess (RS) can be a stopper for the ball (B).

[0115] The length of the recess (RS) in the optical axis direction can be set according to the stroke length of the first lens assembly (200) in the optical axis direction. The maximum stroke length of the first lens assembly (200) can be the distance from the first-first stopper (ST1a) to the second-first stopper (ST2a) in the optical axis direction. The maximum stroke length of the first lens assembly (200) can be smaller than the distance from the first-first stopper (ST1a) to the second-first stopper (ST2a) in the optical axis direction.

[0116]

[0117] The second driving magnet (501) may be provided in the second lens assembly (300) by a vertical magnetization method or the like. The N pole and the S pole of the second driving magnet (501) may both be positioned to face the second coil (502). Accordingly, the N pole and the S pole of the second driving magnet (501) may be respectively positioned to correspond to a region in which current flows in the X-axis direction or the opposite direction in the second coil (502).

[0118] When a magnetic force (DM2) is applied in the Y-axis direction from the N pole of the second driving magnet (501), and a current (DE2) flows in the X-axis direction from the second coil (502) corresponding to the N pole, an electromagnetic force (DEM2) can act in the Z-axis direction according to the interaction of electromagnetic forces (e.g., Fleming's left-hand rule). When a magnetic force is applied in the opposite direction to the Y-axis direction from the S pole of the second driving magnet (501), and a current (DE2) flows in the opposite direction to the X-axis direction from the second coil (502) corresponding to the S pole, an electromagnetic force (DEM2) can act in the Z-axis direction according to the interaction of electromagnetic forces.

[0119] Since the second coil (502) is fixed to the side of the second housing (1200), the second lens assembly (300) in which the second driving magnet (501) is arranged can move in the opposite direction of the Z-axis direction by the electromagnetic force (DEM2) according to the current direction. The direction of the electromagnetic force can be changed depending on the current of the coil and the magnetic force of the magnet. That is, the second driving magnet (501) can move in the opposite direction of the electromagnetic force applied to the second coil (502). In addition, the direction of the electromagnetic force can be changed depending on the current of the coil and the magnetic force of the magnet.

[0120] An electromagnetic force (DEM1) is generated between the second drive magnet (501) and the second coil (502), so that the first lens assembly (200) can move along the first and second guide grooves (GG1a, GG1b) located on the inner surface of the second housing (1200) through the ball (B) in the direction of the optical axis. Accordingly, when the first lens assembly (200) moves in the direction of the optical axis, the first and second guide grooves (GG1a, GG1b) can act as guide rails to prevent tilting of the first lens assembly (200) and guide stroke movement.

[0121] The lengths of the third and fourth guide grooves (GG2a, GG2b) in the optical axis direction can be set according to the stroke length of the second lens assembly (300) in the optical axis direction. The maximum stroke length of the second lens assembly (300) can be the distance from the first-second stopper (ST1b) to the second-second stopper (ST2b) in the optical axis direction. The maximum stroke length of the second lens assembly (300) can be smaller than the distance from the first-second stopper (ST1b) to the second-second stopper (ST2b) in the optical axis direction.

[0122] The recesses (RS1, RS2) formed in the second magnet holder (320) can have a preset length in the optical axis direction (z-axis direction). The balls (B1, B2) can be seated in the recesses (RS1, RS2) of the second magnet holder (320). The distance that the balls (B1, B2) move in the optical axis direction within the recesses can be adjusted. The recesses (RS1, RS2) can be stoppers for the balls (B1, B2).

[0123] The length of the recess (RS1, RS2) in the optical axis direction can be set according to the stroke length of the second lens assembly (300) in the optical axis direction. The maximum stroke length of the second lens assembly (300) can be the distance from the first-second stopper (ST1b) to the second-second stopper (ST2b) in the optical axis direction. The maximum stroke length of the second lens assembly (300) can be smaller than the distance from the first-second stopper (ST1b) to the second-second stopper (ST2b) in the optical axis direction.

[0124]

[0125] The first driving magnet (401) and the first coil (402) can provide driving force (F3A, F3B) to move the first lens assembly (200) along the optical axis direction. The first lens assembly (200) on which the first driving magnet (401) is mounted can move along the optical axis direction by the electromagnetic force (F3A, F3B) between the first coil (402) and the first driving magnet (401). The second lens group (102) mounted on the first lens assembly (200) can also move along the optical axis direction.

[0126] The second driving magnet (501) and the second coil (502) can provide driving force (F4A, F4B) to move the second lens assembly (300) along the optical axis direction. By the electromagnetic force (F4A, F4B) between the second coil (502) and the second driving magnet (501), the second lens assembly (300) on which the second driving magnet (501) is mounted can move along the optical axis direction. The third lens group (103) mounted on the second lens assembly (300) can also move along the optical axis direction.

[0127] The focal length or magnification of the optical system can be changed by moving the second lens group (102) and the third lens group (103). The magnification can be changed by moving the second lens group (102). In other words, zooming can be achieved. The focus can be adjusted by moving the third lens group (103). In other words, auto focusing can be achieved. With this configuration, the camera module (1000) can be a fixed zoom or a continuous zoom.

[0128]

[0129] The base portion or base member of the circuit board may be positioned between the lens portion (100) and the image sensor (IS). Components such as a filter may be fixed to the base member. The base member may be arranged to surround the image sensor. With this configuration, the image sensor is free from foreign substances, etc., thereby improving the reliability of the device. However, in some drawings below, this is omitted and described. However, the present invention may not be limited to this structure.

[0130] The camera module (1000) may be a zoom actuator and an AF (Auto Focus) actuator. For example, the camera module (1000) supports one or more lenses and may perform at least one of an auto focus function and a zoom function by moving the lenses according to a control signal from a predetermined control unit. The first lens assembly (200) may be a fixed zoom or a continuous zoom. The second lens assembly (300) may be a fixed zoom or a continuous zoom. The first lens assembly (200) may provide movement of the second lens group (102). The second lens assembly (300) may provide movement of the third lens group (103).

[0131] In addition to the first lens assembly (200) and the second lens assembly (300), at least one of a third lens assembly (not shown) and a guide pin (not shown) may be disposed. The above-described content may be applied to this. Accordingly, the second camera actuator may perform a high-magnification zooming function through the second driving unit. For example, the first lens assembly (200) and the second lens assembly (300) may be moving lenses that move through the second driving unit and the guide pin (not shown), and the third lens assembly (not shown) may be a fixed lens, but is not limited thereto.

[0132] For example, the third lens assembly (not shown) may perform the function of a focalizer that focuses light on a specific location, and the first lens assembly (200) may perform the function of a variator that refocuses the image focused by the third lens assembly (not shown), which is a condenser, on another location. Meanwhile, in the first lens assembly (200), the distance to the subject or the image distance may change significantly, resulting in a large change in magnification, and the first lens assembly (200), which is a variator, may play an important role in the change in the focal length or magnification of the optical system. Meanwhile, the image focused by the first lens assembly (200), which is a variator, may have a slight difference depending on the location. Accordingly, the second lens assembly (300) may perform a position compensation function for the image focused by the variator. For example, the second lens assembly (300) can perform a compensator function that accurately focuses the point imaged by the first lens assembly (200), which is a variable lens, on the actual image sensor location.

[0133] The image sensor may be located inside or outside the camera module (1000). The image sensor may be located on a circuit board. The image sensor may receive light and convert the received light into an electrical signal. In addition, the image sensor may be formed of a plurality of pixels in an array form. The image sensor may be located on the optical axis.

[0135] Fig. 14 is a perspective view of a mobile terminal to which a camera module according to an embodiment is applied.

[0136] As illustrated in FIG. 14, the mobile terminal (1500) of the embodiment may include a camera module (1000), a flash module (1530), and an autofocus device (1510) provided on the rear.

[0137] The camera module (1000) may include an image capturing function and an autofocus function. For example, the camera module (1000) may include an image-based autofocus function. The camera module (1000) processes still or moving image frames obtained by the image sensor in a shooting mode or a video call mode.

[0138] The processed image frame can be displayed on a predetermined display unit and stored in memory. A camera (not shown) may also be positioned on the front of the mobile terminal body. For example, the camera module (1000) may include a first camera module (1000A) and a second camera module (1000B), and the first camera module (1000A) may implement OIS along with AF or zoom functions.

[0139] The flash module (1530) may include a light-emitting element that emits light internally. The flash module (1530) may be operated by the camera operation of the mobile terminal or by the user's control.

[0140] The autofocus device (1510) may include one of the packages of surface-emitting laser elements as a light-emitting unit. The autofocus device (1510) may include an autofocus function using a laser. The autofocus device (1510) may be mainly used in conditions where the autofocus function using the image of the camera module (1000) is degraded, such as at a close range of 10 m or less or in a dark environment. The autofocus device (1510) may include a light-emitting unit including a vertical cavity surface-emitting laser (VCSEL) semiconductor element, and a light-receiving unit that converts light energy into electrical energy, such as a photodiode.

[0143] Referring to FIG. 15, the vehicle (700) of the embodiment may be equipped with wheels (13FL, 13FR) that rotate by a power source and a predetermined sensor. The sensor may be a camera sensor (2000), but is not limited thereto.

[0144] The camera (2000) may be a camera sensor to which a camera module (1000) according to an embodiment is applied. The vehicle (700) according to the embodiment can obtain image information through the camera sensor (2000) that captures a front image or a surrounding image, and can use the image information to determine a lane non-identification situation and create a virtual lane when the lane is not identified.

[0145] The camera sensor (2000) captures the front of the vehicle (700) to obtain a front image, and a processor (not shown) can analyze objects included in the front image to obtain image information. If objects such as a center divider, curb, or street tree corresponding to a lane, adjacent vehicle, traffic obstruction, or indirect road marking are captured in the image captured by the camera sensor (2000), the processor can detect these objects and include them in the image information. At this time, the processor can obtain distance information to the object detected through the camera sensor (2000) to further supplement the image information.

[0146] 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. The camera sensor (2000) may process still images or moving images obtained by an image sensor (e.g., CMOS or CCD).

[0147] The image processing module can process still images or videos acquired through an image sensor, extract necessary information, and transmit the extracted information to the processor. At this time, the camera sensor (2000) may include a stereo camera to improve object measurement accuracy and secure more information, such as the distance between the vehicle (700) and the object, but is not limited thereto.
