Description

Camera actuator and camera module including the same

[0001] The embodiment 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] Camera actuators may include a driver IC for driving. When the driver IC is driven, heat may be generated. Conventional camera actuators have driver ICs located inside the housing, which can cause issues such as reduced lens resolution due to heat generation from the driver IC.

[0004] Additionally, when the lens assembly moves within the camera actuator, a shock-absorbing poron may be placed within the camera actuator to prevent impact from colliding with the camera actuator. However, if the poron and the lens assembly come into contact, a vacuum may form between the surfaces, preventing them from falling.

[0005] An embodiment provides a camera actuator capable of preventing heat generated in a driver IC from being transferred internally.

[0006] Additionally, it provides a camera actuator that is easy to dissipate heat.

[0007] Additionally, a camera actuator capable of preventing resolution degradation of the lens due to heat is provided.

[0107] FIG. 1 is a perspective view of a camera module according to an embodiment, FIG. 2 is an exploded perspective view of a camera module according to an embodiment, and FIG. 3 is a cross-sectional view taken along line AA' in FIG. 1.

[0108] Referring to FIGS. 1 and 2, a camera module (1) according to an embodiment may be composed of a cover (CV), an OIS actuator (100), a camera actuator (1000), and a circuit board (200).

[0109] The cover (CV) can cover the OIS actuator (100) and / or the camera actuator (1000). The cover (CV) can improve the bonding force between the OIS actuator (100) and the camera actuator (1000).

[0110] Furthermore, the cover (CV) may be made of a material that blocks electromagnetic waves. Accordingly, the OIS actuator (100) and the camera actuator (1000) within the cover (CV) can be easily protected.

[0111] In an embodiment, the OIS actuator (100) can change the path of light. In an embodiment, the OIS actuator (100) can change the path of light vertically through an internal optical member (e.g., a mirror or a prism). By this configuration, even if the thickness of the mobile terminal is reduced, a lens configuration larger than the thickness of the mobile terminal can be placed within the mobile terminal through the change of the path of light, thereby performing magnification, auto-focusing (AF), and OIS (Optical Image Stabilizer) functions.

[0112] The OIS actuator (100) can change the optical path from the second direction to the third direction.

[0113] Additionally, the OIS actuator (100) may include a lens arranged in a predetermined barrel (not shown). For example, the lens may include a fixed focal length lens. Such a fixed focal length lens may also be referred to as a “single focal length lens” or “single lens.”

[0114] The camera actuator (1000) may be placed behind the OIS actuator (100). The camera actuator (1000) may be coupled with the OIS actuator (100). The coupling between the two may be achieved in various ways.

[0115] Additionally, the camera actuator (1000) may be a zoom actuator or an auto focus (AF) actuator. For example, the camera actuator (1000) may support one or more lenses and move the lenses according to a control signal from a predetermined control unit to perform an auto focus function or a zoom function.

[0116] The circuit board (200) may be placed at the rear end of the camera actuator (1000). The circuit board (200) may be electrically connected to the camera actuator (1000) and the OIS actuator (100). In addition, there may be a plurality of circuit boards (200).

[0117] This circuit board (200) is connected to the housing of the camera actuator (1000), and an image sensor may be provided. Furthermore, a base portion including a filter may be mounted on the circuit board (200).

[0118] The camera module according to the embodiment may be comprised of a single or multiple camera modules. For example, the multiple camera modules may include a first camera module and a second camera module. Furthermore, as described above, the camera module may be used interchangeably with terms such as "camera device," "camera device," "imaging device," "imaging module," and "imaging device."

[0119] And the first camera module may include a single or multiple actuators. For example, the first camera module may include an OIS actuator (100) and a camera actuator (1000).

[0120] And the second camera module may be placed in a predetermined housing (not shown) and may include an actuator (not shown) capable of driving a lens unit. The actuator may be a voice coil motor, a micro actuator, a silicon actuator, etc., and may be applied in various ways such as an electrostatic method, a thermal method, a bimorph method, an electrostatic force method, etc., but is not limited thereto. In addition, the camera actuator in this specification may be referred to as an actuator, etc. In addition, a camera module composed of a plurality of camera modules may be mounted in various electronic devices such as a mobile terminal.

[0121] Referring to FIG. 3, a camera module according to an embodiment may include an OIS actuator (100) having an OIS function and a camera actuator (1000) having a zooming function and an AF function.

[0122] Light can be incident into the camera module through an aperture area located on the upper surface of the OIS actuator (100). That is, the light is incident into the interior of the OIS actuator (100) along an optical axis direction (e.g., Y-axis direction) and the light path can be changed to a vertical direction (e.g., Z-axis direction) through an optical member. Then, the light can pass through the camera actuator (1000) and be incident on an image sensor located at one end of the camera actuator (1000) (PATH).

[0123] In this specification, the bottom means one side in the first direction. And the first direction is the X-axis direction in the drawing and can be used interchangeably with the second-axis direction, etc. The second direction is the Y-axis direction in the drawing and can be used interchangeably with the first-axis direction, etc. The second direction is a direction perpendicular to the first direction. In addition, the third direction is the Z-axis direction in the drawing and can be used interchangeably with the third-axis direction, etc. It is a direction perpendicular to both 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. In addition, in the description of the camera actuator (1000) below, the optical axis direction corresponds to the optical path and is the third direction (Z-axis direction), and the following description will be made based on this.

[0124] And by this configuration, the camera module according to the embodiment can improve the spatial limitations of the OIS actuator and the camera actuator by changing the light path. That is, the camera module according to the embodiment can expand the light path while minimizing the thickness of the camera module in response to the change in the light path. Furthermore, it should be understood that the camera actuator can also provide a high range of magnification by controlling the focus, etc. in the expanded light path.

[0125] In addition, the camera module according to the embodiment can implement OIS by controlling the optical path through the OIS actuator, thereby minimizing the occurrence of decent or tilt phenomena and producing the best optical characteristics.

[0126] Furthermore, the camera actuator (1000) may include an optical system and a lens driving unit. For example, the camera actuator (1000) may include at least one of a first lens assembly, a second lens assembly, a third lens assembly, and a guide pin.

[0127] Additionally, the camera actuator (1000) is equipped with a coil and a magnet to perform a high-magnification zooming function.

[0128] For example, the first lens assembly and the second lens assembly may be moving lenses that move via coils, magnets, and guide pins, and the third lens assembly (not shown) may be a fixed lens, but is not limited thereto. For example, the third lens assembly may function as a focal point that focuses light at a specific location, and the second lens assembly may function as a variator that refocuses the image focused by the third lens assembly, which is a focal point, at another location. Meanwhile, in the second lens assembly, the distance to the subject or the image distance may change significantly, resulting in a large change in magnification, and the second lens assembly, 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 point focused by the second lens assembly, which is a variator, may have a slight difference depending on the location. Accordingly, the first lens assembly may function to compensate for the position of the image focused by the variator. For example, the first lens assembly may function as a compensator, accurately focusing the image formed by the second lens assembly onto the actual image sensor location. For example, the first lens assembly and the second lens assembly may be driven by electromagnetic force resulting from the interaction of a coil and a magnet.

By placing the driver unit (IC) inside the groove (G) located on the outside of the housing (1100), heat generated in the driver unit (IC) can be prevented from being transferred to the lens inside the housing (1100), and heat can be easily dissipated to the outside.

[0143] A portion of the groove (G) may be exposed to the second side (S2). At least one side of the groove may be exposed to the second side (S2), thereby allowing at least one side of the groove to be exposed to the outside. By exposing at least one side of the groove to the outside, heat generated in the driver unit (IC) within the groove may be easily dissipated to the outside.

The groove (G) may be extended and disposed on the protrusion (1110). The protrusion (1110) includes a first surface, which is a protruding surface, and the first surface may include a side surface of the groove (G) so that the groove (G) may be exposed to the outside. The protrusion (1110) may overlap a portion of the driver unit (IC) in the first direction. The protrusion (1110) may protrude in the direction of the optical axis, so that the driver unit (IC) may be positioned further away from the lens and heat may be more easily discharged to the outside. In addition, the protrusion (1110) may be positioned in the direction of the optical axis so as not to increase the width of the camera actuator (1000) in the direction perpendicular to the optical axis.

[0173] The driver unit (IC) can receive an optical signal and generate a driving signal. The driver unit (IC) can generate a signal for driving the driver unit (1400) through the optical signal received from the image sensor. In addition, the driver unit (IC) can supply current to the coil unit of the driver unit (1400). The driver unit (IC) can include a driver IC. The driver unit (IC) can be disposed on the substrate (1500). The driver unit (IC) can be disposed on the first sub-substrate (1510). The driver unit (IC) can be disposed on the inside of the first sub-substrate (1510). The driver unit (IC) can be disposed between the housing (1100) and the first sub-substrate (1510). The driver unit (IC) can be disposed on the inside of the first sub-substrate (1510) and can be located inside the groove (G). At least one side of the driver unit (IC) can be exposed to the outside. The driver unit (IC) is arranged inside the home (G) with at least one side exposed to the outside, thereby preventing generated heat from reaching the lens and facilitating heat dissipation to the outside.

[0174] A portion of the driver unit (IC) may be arranged to overlap with the protrusion (1110) in the first direction.

The driver unit (IC) may partially overlap with the second driver unit (1420) in the optical axis direction. The driver unit (IC) may partially overlap with the second driver unit (1420) in the optical axis direction, thereby facilitating heat dissipation without increasing the width of the camera actuator (1000) in the first direction.

[0177] Figure 17 is an enlarged view of part K1 in Figure 6.

[0178] Referring to FIG. 17, the width (a1) of the groove (G) in the first direction according to the embodiment may be greater than the width (b1) of the driver unit (IC) in the first direction. Since the width (a1) of the groove (G) in the first direction is greater than the width (b1) of the driver unit (IC) in the first direction, the driver unit (IC) may not be in direct contact with the housing (1100). Since the driver unit (IC) is positioned without being in direct contact with the housing (1100), heat can be prevented from being transferred to a lens positioned inside the housing (1100), and heat can be more easily released to the outside through the air.

[0179] The width (a1) in the first direction of the home (G) may be smaller than the width (c1) in the first direction of the protrusion (1110).

[0180] The width (a3) ​​in the optical axis direction of the groove (G) may be greater than the width (c3) in the optical axis direction of the protrusion (1110). The width (a3) ​​in the optical axis direction of the groove (G) may be greater than the width (b3) in the optical axis direction of the driver unit (IC).

[0182] Referring to FIG. 18, the width (c2) in the optical axis direction of the protrusion (1110) according to the embodiment and in the second direction perpendicular to the first direction may be equal to the width (c2) in the second direction of the first side. In addition, the width (a2) in the second direction of the groove (G) may be smaller than the width (c2) in the second direction of the protrusion (1110) and the first side. The width (a2) in the second direction of the groove (G) may be larger than the width (b2) in the second direction of the driver unit (IC).

[0185] The width (d1, e1) in the optical axis direction of the first extension portion (G1) and the second extension portion (G2) may be smaller than the width (a3) ​​in the optical axis direction of the groove (G). The first extension portion (G1) and the second extension portion (G2) may have a constant width (d2, e2) in the second direction to form a wider empty space inside the groove (G). By forming a wider empty space inside the groove (G), it is possible to facilitate heat dissipation to the outside through the empty space. In addition, while securing a wide empty space in the second direction of the first extension portion (G1) and the second extension portion (G2) by the width (d2, e2), it is possible to prevent foreign substances from entering from the outside.

The stopper portion can overlap with both the first-first prevention portion (P1-1) and the first-second prevention portion (P1-2) to make the contact more stable and more effectively prevent a vacuum state. In addition, when the stopper portion comes into contact, the contact can be made while maintaining balance.

[0253] The distance (d2) in the first direction of the second-first prevention portion (P2-1) and the second-second prevention portion (P2-2) is smaller than the first direction width (w2) of the mounting portion and the stopper portion, so that when the stopper portion comes into contact with the first to fourth surfaces (F1, F2, F3, F4), the stopper portion can overlap with the second-first prevention portion (P2-1) and the second-second prevention portion (P2-2) in the optical axis direction. The stopper portion can overlap with both the second-first prevention portion (P2-1) and the second-second prevention portion (P2-2) to make the contact more stable and more effectively prevent a vacuum state. In addition, when the stopper portion comes into contact, the contact can be made while maintaining balance.

[0254] According to the embodiment, the length (l1-1, l1-2) of the first-first prevention unit (P1-1) or the first-second prevention unit (P1-2) in the first direction may be shorter than the length (l2-1, l2-2) of the second-first prevention unit (P2-1) or the second-second prevention unit (P2-2) in the second direction.

[0255] The length (l1-1) of the first-first prevention section (P1-1) in the first direction and the length (l1-2) of the first-second prevention section (P1-2) in the first direction may be the same as each other. The length (l2-1) of the second-first prevention section (P2-1) in the second direction and the length (l2-2) of the second-second prevention section (P2-2) in the second direction may be the same as or different from each other.

In the case of the second side to the fourth side (F2, F3, F4), the length (l2-1) of the second-direction anti-glare portion (P2-1) may be shorter than the length (l2-2) of the second-direction anti-glare portion (P2-2).

[0256] The length (l1-1, l1-2) of the first-first prevention portion (P1-1) or the first-second prevention portion (P1-2) in the first direction is arranged shorter than the length (l2-1, l2-2) of the second-first prevention portion (P2-1) or the second-second prevention portion (P2-2) in the second direction so that the fixing portion (A) on which the stopper portion is fixed and the fixing portion (P) can overlap each other in the optical axis direction. The fixing portion (A) and the fixing portion (P) can be stably contacted by overlapping each other in the optical axis direction, and a vacuum state can be prevented more effectively.

[0257] According to the embodiment, the distances (d3a, d3b) in the second direction from the 1-3 prevention unit (P1-3) to the 1-1 prevention unit (P1-1) and the 1-2 prevention unit (P-1-2) may be the same.

[0258] The first-third prevention unit (P1-3) may be arranged between the first-first prevention unit (P1-1) and the first-second prevention unit (P-1-2). The first-third prevention unit (P1-3) may be arranged parallel to the first-first prevention unit (P1-1) and the first-second prevention unit (P-1-2) in the first direction. The distance (d3a) between the first-third prevention unit (P1-3) and the first-first prevention unit (P1-1) in the second direction may be the same as the distance (d3b) between the first-third prevention unit (P1-3) and the first-second prevention unit (P-1-2) in the second direction. The 1-3 prevention section (P1-3) is arranged at the same distance in the second direction as the 1-1 prevention section (P1-1) and the 1-2 prevention section (P-1-2), so that the stopper section can stably contact the mounting section and prevent a vacuum state more effectively.

[0259] Fig. 39 is a perspective view of a mobile terminal to which a sensor module according to an embodiment is applied.

[0260] Referring to FIG. 39, the mobile terminal (2500) of the embodiment may include a camera module (2000), a flash module (2530), and an autofocus device (2510) provided on the rear.

[0261] The camera module (2000) may include an image capturing function and an autofocus function. For example, the camera module (2000) may include an autofocus function using an image.

[0262] The camera module (2000) processes still or moving image frames obtained by the image sensor in shooting mode or video call mode.

[0263] The processed image frame can be displayed on a predetermined display unit and stored in memory. A camera (not shown) may also be placed on the front of the mobile terminal body.

[0264] For example, the camera module (2000) may include a first camera module (2000A) and a second camera module (2000B), and OIS may be implemented together with AF or zoom functions by the first camera module (2000A). In addition, AF, zoom, and OIS functions may be implemented by the second camera module (2000B). In this case, since the first camera module (2000A) includes both the OIS actuator and the camera actuator described above, miniaturization of the camera module can be easily achieved by changing the optical path.

[0265] The flash module (2530) may include a light-emitting element that emits light internally. The flash module (2530) may be operated by the camera operation of the mobile terminal or by the user's control.

[0272] The camera sensor (2000) may be a camera sensor to which a camera module according to an embodiment is applied. The vehicle (700) of the embodiment can obtain image information through the camera sensor (2000) that captures a forward 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.

[0273] For example, a camera sensor (2000) can capture the front of a vehicle (700) to obtain a front image, and a processor (not shown) can analyze an object included in the front image to obtain image information.

[0274] For example, if objects such as a center divider, curb, or street tree, which correspond to a lane, adjacent vehicle, traffic obstruction, or indirect road marking, are captured in an image captured by a 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 from the object detected by the camera sensor (2000) to further supplement the image information.

[0275] 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.

[0276] The camera sensor (2000) can process still images or moving images obtained by an image sensor (e.g., CMOS or CCD).

[0277] 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.

[0278] At this time, the camera sensor (2000) may include a stereo camera to improve the measurement accuracy of the object and to secure more information such as the distance between the vehicle (700) and the object, but is not limited thereto.
