Technical Field

[0002] The present embodiment relates to a lens driving device, a camera module, and an optical instrument. Background Art

[0003] This section provides background information related to the present disclosure which is not necessarily prior art.

[0004] Along with the popularization of widespread use of various mobile terminals and the commercialization of wireless Internet services, demands by consumers related to mobile terminals have also become diversified to allow various types of peripheral devices to be installed on the mobile terminals.

[0005] The camera module is one of representative items for capturing an object in a picture or video. Meanwhile, the camera module has recently applied an AF (AutoFocus) function that automatically adjusts the focus according to the distance to the object. In addition, the camera module has recently applied an OIS (Optical Image Stabilization) function that prevents an image from being shaken due to a photographer's hand trembling.

[0006] On the other hand, the conventional camera module has a disadvantage in that the stopper of the bobbin is damaged by collision with the housing during a reliability test.

[0007] Also, the conventional camera module has disadvantages in that it is difficult to apply the damper on the supporting member in a predetermined amount and the applied damper may be lost.

[0008] Furthermore, the conventional camera module also has the disadvantage that a shape design is required to have elasticity, which requires an elastic member to elastically connect the bobbin with respect to the housing.

[0009] Furthermore, the conventional camera module also has a disadvantage that the cover member is pushed back (pushed) and rotated.

[0010] Furthermore, the conventional camera module also has a disadvantage in that during the process of coupling the sensor board to the upper elastic member, flux evaporates into the air to cause uncured solder balls to scatter in all directions around the sensor board.

[0011] This can cause serious problems because the ejection of uncured solder balls becomes the root cause of solder foreign matter during shock reliability testing. Summary of the invention

[0119] Certain exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. When describing the reference numerals of each element, if possible, the same reference numeral will be assigned to the same element although it is indicated differently in other drawings.

[0120] When describing the elements in the exemplary embodiments of the present invention, the terms first, second, A, B, (a), (b) and the like may be used. These terms may only be used to distinguish one element from another element, and the nature, order or sequence is not limited by these terms. When an element is referred to as "leading to", "connected to" or "connected to" another element, it should be understood that the element may directly lead to, connect or be connected to the other element, or there may be an intermediate element between the element and the other element.

[0121] The term "optical axis direction" used hereinafter may be defined as the optical axis direction of the lens module coupled to the lens driving device. Meanwhile, the "optical axis direction" may be used interchangeably with the vertical direction, the z-axis direction, and other directions.

[0122] The term "auto focus function" used hereinafter may be defined as a function of automatically matching the focus of an object to obtain a clear image of the object from the image sensor by adjusting the distance to the image sensor by moving the lens module along the optical axis direction according to the distance to the object. Meanwhile, "auto focus" may be used interchangeably with "AF (Auto Focus)".

[0123] The term "hand shake correction function" used hereinafter may be defined as a function of moving or tilting the lens module in a direction perpendicular to the optical axis to offset the vibration (movement) generated by the external force on the image sensor. Meanwhile, "hand shake correction" may be used interchangeably with "OIS (Optical Image Stabilization)".

[0124] Hereinafter, any one of the AF driving coil (220), the driving magnet (320), and the OIS driving coil (422) may be referred to as a "first driving section", another one may be referred to as a "second driving section", and the remaining other one may be referred to as a "third driving section". Meanwhile, the AF driving coil (220), the driving magnet (320), and the OIS driving coil (422) may be interchangeably arranged by manually changing their positions.

[0125] Hereinafter, any one of the AF driving coil ( 220 ) and the OIS driving coil ( 422 ) may be referred to as a “first coil” and the other may be referred to as a “second coil”.

[0128] Hereinafter, the configuration of an optical instrument according to an exemplary embodiment of the present invention will be described.

[0129] The optical device may be any one of a handheld phone, a mobile phone, a smart phone, a portable intelligent device, a digital camera, a laptop computer, a digital broadcast terminal, a PDA (Personal Digital Assistant), a PMP (Portable Multimedia Player), and a navigation device. However, the present invention is not limited thereto, and may include any device capable of capturing an image or a photograph.

[0130] The optical device may include a main body (not shown), a camera module, and a display portion (not shown). However, any one or more of the main body, the camera module, and the display portion may be omitted or changed.

[0131] The main body may form the outer shape of the optical device. For example, the main body may include a cubic shape. In another example, the main body may be at least partially circular. The main body may accommodate a camera module. One surface of the main body may be provided with a display unit. One surface of the main body may be provided with a display unit and a camera module, and another surface of the main body (the surface opposite to the one surface) may be additionally provided with a camera module.

[0132] The camera module may be provided on the main body. The camera module may be provided on one surface of the main body. The camera module may be partially accommodated in the main body. The camera module may be formed in plurality. A plurality of camera modules may be provided on one surface and another surface of the main body, respectively. The camera module may capture an image of an object.

[0133] The display unit may be provided on the main body. The display unit may be provided on one surface of the main body. That is, the display unit may be provided on the same surface as the surface on which the camera module is provided. Alternatively, the display unit may be provided on another surface of the main body. The display unit may be provided on a surface at a surface opposite to the surface on which the camera module is provided. The display unit may output an image captured by the camera module.

[0134] Hereinafter, a configuration of a camera module according to an exemplary embodiment of the present invention will be described with reference to the accompanying drawings.

[0135] The camera module may include a lens driving device, a lens module (not shown), an infrared filter (not shown), a PCB (not shown), an image sensor (not shown), and a controller (not shown). However, any one or more of the lens driving device, the lens module, the infrared filter, the PCB, the image sensor, and the controller may be omitted or changed from the camera module.

[0136] The lens module may include at least one lens. The lens module may include a lens and a lens barrel. The lens module may include one or more lenses (not shown) and a lens barrel for accommodating the lens. However, one element in the lens module is not limited to the lens barrel, and any retaining structure capable of supporting one or more lenses may meet the needs of the lens module. The lens module may be coupled to the interior of the lens drive device. The lens module may be coupled to the bobbin (210) of the lens drive device. The lens module may move integrally with the bobbin (210). The lens module may be coupled to the bobbin (210) by means of an adhesive (not shown). For example, the lens module may be threadedly connected to the bobbin (210). At the same time, the light that has passed through the lens module may be irradiated on the image sensor.

[0137] The infrared filter can block light in the infrared region from being incident on the image sensor. The infrared filter can be placed between the lens module and the image sensor. For example, the infrared filter can be provided on a retaining member (not shown) provided separately from the base (430). In another example, the infrared filter can be mounted on a through hole (431) of the base (430). The infrared filter can be formed of a film material or a glass material. The infrared filter can be formed by allowing an infrared cut-off coating material to be coated on a plate-shaped filter such as an imaging plane protective cover glass or cover glass. For example, the infrared filter can be an infrared absorption filter (blue filter) that absorbs infrared rays. In another example, the infrared filter can be an infrared reflection filter (IR cut-off filter) that reflects infrared rays.

[0138] The lens driving device may be disposed on the upper surface of the PCB. The PCB may be disposed at the lower surface of the lens driving device. The PCB may be coupled to the lens driving device. The PCB may be provided with an image sensor. The PCB may be electrically connected to the image sensor. For example, a retaining member may be placed between the PCB and the lens driving device. In this case, the image sensor may be accommodated inside the retaining member. In other examples, the PCB may be directly provided with the lens driving device. In this case, the image sensor may be accommodated inside the lens driving device. Through this structure, light that has passed through the lens module coupled to the lens driving device may be irradiated on the image sensor. The PCB may supply power (current) to the lens driving device. At the same time, the PCB may be provided with a controller for controlling the lens driving device.

[0139] The image sensor may be disposed on a PCB. The image sensor may be electrically connected to the PCB. For example, the image sensor may be connected to the PCB by means of SMT (Surface Mounting Technology). In another example, the image sensor may be connected to the PCB by means of flip chip technology. The image sensor may be configured to match the lens module by means of an optical axis. In other words, the optical axis of the image sensor and the optical axis of the lens module may be aligned, and through the aligned optical axes, the image sensor may obtain light that has passed through the lens module. The image sensor may convert light irradiated on the effective image area into an electrical signal. The image sensor may be a CCD (charge coupled device), a MOS (metal oxide semi-conductor), a CPD, and a CID. However, the type of image sensor is not limited thereto, and may include any structure capable of converting incident light into an electrical signal.

[0140] The controller may be mounted on a PCB. For example, the controller may be disposed inside the lens driving device. In another example, the controller may be disposed outside the lens driving device. The controller may individually control the direction, intensity, and amplitude of the current supplied to the AF driving coil (220) and the OIS driving coil (422) of the lens driving device. The controller may perform any one or more of the AF function and the OIS function of the camera module by controlling the lens driving device. That is, the controller may move or tilt the lens module along the optical axis direction or in a direction perpendicular to the optical axis direction by controlling the lens driving device. In addition, the controller may perform any one or more of the feedback control of the AF function and the feedback control of the OIS function. More specifically, the controller may receive the position of the bobbin (210) or the housing (310) detected by the first sensor unit (700) to perform the AF feedback control by controlling the current applied to the AF driving coil (220). In addition, the controller can receive the position of the bobbin (210) or the housing (310) detected by the second sensor (800) to perform OIS feedback control by controlling the current applied to the OIS drive coil (422). Therefore, the feedback control of the controller mentioned above can be generated in real time to allow more accurate AF function and OIS function to be performed.

Specifically, any one or more of the first sensing unit (700) and the second sensing unit (800) may be omitted due to elements used for AF feedback control and OIS feedback control.

[0144] The cover member (100) may be accommodated inside the housing (310). The cover member (100) may be coupled to the base (430). The cover member (100) may form the outer shape of the lens driving device. The cover member (100) may take the shape of a cube with an open bottom. However, the present invention is not limited thereto. The cover member (100) may be a non-magnetic material. If the cover member (100) is formed of a magnetic material, the magnetic force of the cover member (100) may affect any one or more of the driving magnet (320), the sensing magnet (730) and the compensating magnet (740). The cover member (100) may be formed of a metal material. More specifically, the cover member (100) may be formed of a metal plate. In this case, the cover member (100) may shield EMI (electro magnetic interference). Due to the characteristics of the cover member (100), the cover member (100) may be referred to as an "EMI shielding cover". The cover member (100) may be connected to a ground part of the PCB (40), and the cover member (100) may be grounded through the ground part. The cover member (100) may shield radio waves generated from outside the lens driving device from being introduced into the cover member (100). In addition, the cover member (100) may shield radio waves generated from inside the cover member (100) from being released to the outside of the cover member (100).

[0145] The cover member (100) may include an upper plate (101) and a side plate (102).

The inner space formed by the cover member (100) and the base (430) may be provided with a first mover (200), a second mover (300), a stator (400), an elastic member (500) and a support member (600). Through this structure, the cover member (100) can protect the internal elements from the impact of external impacts and at the same time prevent external foreign contaminants from being introduced inward.

[0146] The cover member (100) may include an opening (110) and a recessed portion (120). However, any one of the opening (110) and the recessed portion (120) may be omitted or changed from the cover member (100).

[0147] The opening (110) may be formed on the upper plate (101) of the cover member (100). The opening (110) may expose the lens module upward. The opening (110) may adopt a shape corresponding to the shape of the lens module. The size of the opening (110) may be larger than the diameter of the lens module to allow the lens module to be assembled through the opening (110). Light that has been introduced into the opening (110) and passed through the opening (110) may pass through the lens module. At this time, the light that has passed through the lens module may be converted into an electrical signal by an image sensor and may be obtained as an image.

The recessed surface (121) and the second connection surface may be supported by the second lug (442).

[0151] The first mover (200) can be connected to the lens module, which is an element of the camera module (but the lens module can also be interpreted as an element of the lens driving device). The first mover (200) can be accommodated in the interior of the lens module. The inner periphery surface of the first mover (200) can be connected by the outer periphery surface of the lens module. The first mover (200) can move by interacting with the second mover (300) and / or the stator (400). At this time, the first mover (200) can move integrally with the lens module. The first mover (200) can move for AF focusing function. At this time, the first mover (200) can be referred to as "AF mover". However, it should be noted that the first mover (200) is not limited to a component that moves only for the autofocus function. The first mover (200) can also move for OIS function.

[0152] The first mover (200) may include a bobbin (210) and an AF driving coil (220). However, any one or more of the bobbin (210) and the AF driving coil (220) may be omitted or changed from the first mover (200).

The bobbin (210) may move along the optical axis direction inside the housing (310). The bobbin (210) may be disposed inside the housing (310) to move along a first direction. At this time, the first direction may be the optical axis direction. The bobbin (210) may be disposed on the through hole (311) to move along the optical axis direction. The bobbin (210) may be coupled to the lens module. The inner peripheral surface of the bobbin (210) may be coupled by the outer peripheral surface of the lens module. The bobbin (210) may be coupled by the AF drive coil (220). The outer peripheral surface of the bobbin (210) may be coupled by the AF drive coil (220).

The inner circumferential surface of the through hole (211) may be formed with a thread corresponding to the thread formed on the outer circumferential surface of the lens module. That is, the through hole (211) may be threadedly connected to the lens module. An adhesive may be placed between the lens module and the bobbin (210). At this time, the adhesive may be an epoxy resin hardened by any one or more of UV, heat and laser.

[0157] The drive unit coupling portion (212) may be coupled by the AF drive coil (220). The drive unit coupling portion (212) may be formed on the outer peripheral surface of the bobbin (210). The drive unit coupling portion (212) may be formed by a recess formed by allowing a portion of the outer peripheral surface of the bobbin (210) to be recessed inward. At this time, the drive unit coupling portion (212) may be accommodated by at least a portion of the AF drive coil (220). The drive unit coupling portion (212) may be formed integrally with the outer peripheral surface of the bobbin (210). For example, the drive unit coupling portion (212) may be continuously formed along the outer peripheral surface of the bobbin (210). At this time, the drive unit coupling portion (212) may be wound with the AF drive coil (220). In another example, the drive unit coupling portion (212) may be formed in plurality, and each drive unit coupling portion is spaced apart from each other. At this time, the AF drive coil (220) may also be formed in plurality to be respectively coupled to the drive unit coupling portion (212). In another example, the driving part coupling part (212) may be formed by an open upper side or an open bottom side. In this case, the AF driving coil (220) may be inserted into the driving part coupling part (212) through the opening in a pre-wound state and coupled to the driving part coupling part (212).

For example, the lug of the upper coupling portion (213) may be coupled by being inserted into a recess or hole of the inner portion (512) of the upper elastic member (510). At this time, the lug of the upper coupling portion (213) may be fused to the hole of the inner portion (512) while being inserted into the hole of the inner portion (512) to fix the upper elastic member (510) between the upper surface of the bobbin (210) and the fused lug.

[0160] The upper coupling portion (213) may include a first lug (2131) and a second lug (2132). The first lug (2131) and the second lug (2132) may be spaced apart from each other. The first lug (2131) and the second lug (2132) may guide the positioning of the upper elastic member (510).

[0161] The first lug (2131) may be coupled to the first hole (5121). The diameter of the first lug (2131) may be larger than the diameter of the second lug (2132).

At this time, the lug of the lower coupling portion may be fused while being inserted into the hole of the inner portion (522) to fix the lower elastic member (520) between the lower surface of the bobbin (210) and the fused lug.

[0164] The lug (215) may protrude from the upper surface of the bobbin (210). The lug (215) may be provided with a second damper (920). The lug (215) may be coated with a second damper (920). The inner surface of the lug (215) may be formed by a curved surface (2151). The outer surface of the lug (215) may be formed by a flat surface (2152).

[0165] The clamp recess (216) may be formed on the upper surface of the bobbin (210) by recessing. The clamp recess (216) may be used as a clamp to clamp the bobbin (210) during the assembly process of the lens driving device. In particular, when the lens module is threadedly connected to the bobbin (210), the clamp recess may be used to clamp the bobbin (210) to prevent the bobbin (210) from rotating. The clamp recess (216) may include a first recess and a second recess, each of which is formed in a shape corresponding to each other on the upper surface of the opposite side. The first recess and the second recess may be formed on one side opposite to each other. The first recess and the second recess may be formed in the same shape. The first recess and the second recess may be formed by being spaced apart from the sensing magnet (730) and the compensation magnet (740). A virtual straight line connecting the center of the first recess with the center of the second recess may intersect a virtual straight line connecting the center of the sensing magnet (730) with the center of the compensation magnet (740) on the optical axis. A virtual straight line connecting the center of the first recess with the center of the second recess may orthogonally intersect a virtual straight line connecting the center of the sensing magnet (730) with the center of the compensation magnet (740).

[0166] The first stopper (217) and the second stopper (218) may be spaced apart from each other. The first stopper (217) and the second stopper (218) may constrain the lower movement limit of the bobbin (210). That is, each of the first stopper (217) and the second stopper (218) may serve as a lower stopper for the bobbin.

[0167] The first stopper (217) may be spaced apart from the second stopper (218). The first stopper (217) may overlap with the second mover (300) in the optical axis direction. The first stopper (217) may overlap with the housing (310) in the optical axis direction. At least a portion of the first stopper (217) may be disposed on the upper side of the housing (310). The first stopper (217) may protrude from the outer peripheral surface of the bobbin (210). The first stopper (217) may protrude from the outer side surface of the bobbin (210). When the bobbin (210) moves, the first stopper (217) may contact the housing (310). A portion of the lower surface of the first stopper (217) may contact with the AF drive coil (220). A portion of the lower surface of the first stopper (217) may make surface contact with the AF drive coil (220). A lower surface of the first stopper (217) may be disposed at a region lower than a lower surface of the second stopper (218).

[0168] The second stopper (218) may be spaced apart from the first stopper (217). The second stopper (218) may overlap with the second mover (300) in the optical axis direction. The second stopper (218) may overlap with the driving magnet (320) in the optical axis direction. The second stopper (218) may overlap with the housing (310) in the optical axis direction. The second stopper (218) may protrude from the outer peripheral surface of the bobbin (210). The second stopper (218) may protrude from the outer side surface of the bobbin (210). When the bobbin (210) moves, the second stopper (218) may contact the driving magnet (320). The lower surface of the second stopper (218) may be arranged at an area higher than the lower surface of the first stopper (217).

[0169] In the present exemplary embodiment, the distance between the first stopper (217) and the second mover (300) in the optical axis direction may be different from the distance between the second stopper (218) and the second mover (300) in the optical axis direction. The distance between the first stopper (217) and the second mover (300) in the optical axis direction may be shorter than the distance between the second stopper (218) and the second mover (300) in the optical axis direction. The distance between the first stopper (217) and the second mover (300) in the optical axis direction may be longer than the distance between the second stopper (218) and the second mover (300) in the optical axis direction. That is, the moving limit distance of the first stopper (217) and the moving limit distance of the second stopper (218) may be different, so when the bobbin (210) moves, any one of the first stopper (217) and the second stopper (218) may be collided first and the other may be collided later, so that the impact generated from the first stopper (217) and the second stopper (218) can be dispersed. As a result, the first stopper (217) and the second stopper (218) can be prevented from being damaged.

[0170] In the present exemplary embodiment, the distance between the first stopper (217) and the housing (310) in the optical axis direction may be shorter than the distance between the second stopper (218) and the driving magnet (320) in the optical axis direction. As a result, when the bobbin (210) moves downward, the first stopper (217) of the bobbin (210) may first collide with the housing (310), and the second stopper (218) may collide with the driving magnet (320) later, and therefore, the driving magnet (320) can be prevented from being separated from the housing (310) because the force of the second stopper (218) colliding with the driving magnet (320) can be weakened. For example, the distance between the first stopper (217) and the housing (310) in the optical axis direction may be 125 μm to 135 μm, and the distance between the second stopper (218) and the driving magnet (320) in the optical axis direction may be 135 μm to 145 μm. Furthermore, the distance between the first stopper (217) and the housing (310) in the optical axis direction may be 130 μm, and the distance between the second stopper (218) and the driving magnet (320) in the optical axis direction may be 140 μm.

[0171] In the present exemplary embodiment, the first stopper (217) may be provided on the side where the corner of the housing (310) is located, and the second stopper (218) may be provided on the side where the side of the housing (310) is located. The first stopper (217) may be provided on the side where the second corner (306) is located and the side where the fourth corner (308) is located, respectively. That is, two first stoppers (217) may be provided. The first stopper (217) may be formed only on the area where the sensing magnet (730) and the compensating magnet (740) are not provided. In other words, two of the four corners of the bobbin (210) may be formed with the first stopper (217), and the remaining two corners may be formed with the sensing magnet (730) and the compensating magnet (740). The second stopper (218) may be provided on the first to fourth sides (301, 302, 303, 304), respectively. That is, the second stopper (218) may be formed in four (4) pieces.

[0172] In a modification, the first stopper (217) may be provided on the side where the side portion of the housing (310) is located, and the second stopper (218) may be provided on the side where the corner portion of the housing (310) is located.

[0173] The lower surface of the first stopper (217) may overlap with the upper surface of the protruding portion of the housing (310) in the optical axis direction, and through this structure, when the bobbin (210) moves downward, the lower surface of the first stopper (217) of the bobbin (210) may contact the upper surface of the protruding portion. The upper surface of the protruding portion of the housing (310) may include a recessed portion provided on an area corresponding to the outer distal end portion or the lower surface of the first stopper (217).

[0174] In the present exemplary embodiment, since the recess is provided on the area corresponding to the outer distal end or the lower surface of the first stopper (217), the moment load generated from the first stopper (217) can be reduced. Alternatively, by this structure, the possibility of generating foreign matter can be reduced because when the first stopper (217) and the upper surface of the protrusion of the housing (310) contact each other, the contact area can be reduced by the recess provided on the upper surface of the protrusion of the housing (310). Alternatively, the phenomenon of cracks generated from the first stopper (217) can be minimized. More specifically, when the recess is not formed on the protrusion of the housing (310), the outer distal end of the first stopper (217) can collide with the protrusion of the housing (310), and when the recess is formed, the outer distal end of the first stopper (217) is prevented from colliding with the protrusion of the housing (310), but the inner side deeper than the outer distal end of the first stopper (217) may collide with the protrusion of the housing (310). When comparing the two cases, it can be noted that because the moment load becomes larger when an impact is generated on the outer side of the first stopper (217), the moment load generated when the recessed portion is formed is smaller.

[0175] The second stopper (218) may include a main body (2181) and a protrusion (2182). The second stopper (218) may include a main body (2181) and a protrusion (2182), wherein the main body (2181) protrudes from the outer surface of the bobbin (210) in a direction perpendicular to the optical axis, and the protrusion (2182) protrudes from the lower surface of the main body (2181) in the direction of the optical axis. However, the structure may also be explained by an explanation that a recess is formed on the lower surface of the main body (2181). The protrusion (2182) may overlap with the driving magnet (320) in the direction of the optical axis. The protrusion (2182) may include a region in which, in a direction perpendicular to the optical axis, the distance from the outer surface of the bobbin (210) to the outer surface of the protrusion (2182) is shorter than the distance from the outer surface of the bobbin (210) to the outer surface of the main body (2181). The extension length from the outer surface of the bobbin (210) to the protrusion (2182) may be shorter than the extension length from the outer surface of the bobbin (210) to the body (2181). The protrusion (2182) may protrude from the lower surface of the body (2181). That is, the protrusion (2182) may be formed at the lower side of the body (2181).

[0176] In one modification, the recess structure of the protrusion of the housing (310) may be formed at a side where the second stopper (218) is located. In addition, the protrusion (2182) structure may be formed at the first stopper (217). The lower surface of the first stopper (217) may include a first recess that overlaps with the second mover (300) in the optical axis direction. At this time, the first recess may correspond to an area on the lower surface of the body (2181) where the protrusion (2182) is not formed. In addition, the lower surface of the second stopper (218) may include a second recess that overlaps with the second mover (300) in the optical axis direction. At this time, the second recess may correspond to the first recess in structure.

[0177] The present exemplary embodiment can reduce the moment load generated from the second stopper (218) by forming the protrusion (2182) shorter than the main body (2181), thereby minimizing the phenomenon of cracks generated from the second stopper. More specifically, when only the main body (2181) is formed, the outer distal end of the main body (2181) can collide with the driving magnet (320), and when the protrusion (2182) is formed, the outer distal end of the protrusion (2182) can collide with the driving magnet. When comparing the two cases, the moment load generated from the second stopper (218) when the protrusion (2182) is collided can be smaller than the moment load generated from the second stopper (218) when the main body (2181) is collided.

[0178] The third stopper (219) may be formed by protruding from the upper surface of the bobbin (210). The third stopper (219) may overlap with the cover member (100) in the optical axis direction, and the structure in which the third stopper (219) overlaps with the cover member (100) in the optical axis direction may allow the third stopper (219) to limit the movement limit of the bobbin (210). Through the configuration, the third stopper (219) may constrain the movement limit of the bobbin (210). That is, the third stopper (219) may serve as an upper stopper of the bobbin (210).

[0179] In the present exemplary embodiment, the upper surface of the housing (310) may be formed with a receiving recess for avoiding burrs of the upper elastic member (510).

[0180] The AF drive coil (220) may be disposed on the bobbin (210). The AF drive coil (220) may be disposed at the outer peripheral surface of the bobbin (210). The AF drive coil (220) may be directly wound on the bobbin (210). The AF drive coil (220) may face the drive magnet (320). In this case, when current is supplied to the AF drive coil (220) to form a magnetic field around the AF drive coil (220), the AF drive coil (220) may move relative to the drive magnet (320) in response to an electromagnetic interaction between the AF drive coil (220) and the drive magnet (320). The AF drive coil (220) may electromagnetically interact with the drive magnet (320). The AF drive coil (220) may move the bobbin (210) relative to the housing (310) along the optical axis through the electromagnetic interaction with the drive magnet (320). For example, the AF drive coil (220) may be an integrally formed coil. In another example, the AF driving coil (220) may include a plurality of coils, each coil being spaced apart from each other. The AF driving coil (220) may include four (4) coils, each coil being spaced apart from each other. In this case, the four coils may be disposed at the outer peripheral surface of the bobbin (210) to allow two adjacent coils to form 90° with each other.

[0181] The AF drive coil (220) may include a pair of lead cables for power supply. At this time, the pair of lead cables of the AF drive coil (220) may be electrically connected to the fourth upper elastic unit (505) and the sixth upper elastic unit (506) which are elements of the upper elastic member (510). That is, the AF drive coil (220) may receive power through the upper elastic member (510). More specifically, the AF drive coil (220) may receive power sequentially through the PCB (10), the substrate (410), the support member (600) and the upper elastic member (510). Alternatively, the AF drive coil (220) may receive power from the lower elastic member (520).

[0182] The second mover (300) may internally accommodate at least a portion of the first mover (200). The second mover (300) may move the first mover (200) or may move together with the first mover (200). The second mover (300) may move by interaction with the stator (400). The second mover (300) may move for an OIS function. At this time, the second mover (300) may be referred to as an "OIS mover". The second mover (300) may move integrally with the first mover (200) for an OIS function.

[0183] The second mover (300) may include a housing (310) and a driving magnet (320). However, any one or more of the housing (310) and the driving magnet (320) may be omitted or changed from the second mover (300).

[0184] The housing (310) may be disposed at the outside of the bobbin (210). The housing (310) may accommodate at least a portion of the bobbin (210) at the inside of the housing (310). For example, the housing (310) may be in the shape of a cube. The housing (310) may include side portions and corner portions formed between the side portions. The housing (310) may include four side surfaces and four corner portions disposed between the four side surfaces. The housing (310) may be provided with a driving magnet (320). For example, each of the side surfaces of the housing (310) may be provided with a driving magnet (320). In another example, each of the four corner portions of the housing (310) may be provided with a driving magnet (320). At least a portion of the outer peripheral surface of the housing (310) may be in a shape corresponding to the shape of the inner peripheral surface of the cover member (100). In particular, the outer peripheral surface of the housing (310) may adopt a shape corresponding to the shape of the inner peripheral surface of the side plate (102) of the cover member (100). The housing (310) may be formed of an insulating material. The housing (310) may be formed of a material different from the material of the cover member (100). In consideration of productivity, the housing (310) may be formed of an injection molded object. The outer side surface of the housing (310) may be spaced apart from the inner side surface of the side plate (102) of the cover member (100). The housing (310) may be moved at a discrete space between the housing (310) and the cover member (100) to perform OIS driving. The upper surface of the housing (310) may be connected by an upper elastic member (510). The lower surface of the housing (310) may be connected by a lower elastic member (520).

[0185] The housing (310) may include first to fourth side portions (301, 302, 303, 304). The housing (310) may include first to fourth side portions (301, 302, 303, 304) formed between the first corner portion to the fourth corner portion (305, 306, 307, 308). The first side portion (301) and the third side portion (303) may be disposed on opposite sides to each other. The second side portion (302) and the fourth side portion (304) may be disposed on opposite sides to each other. The first side portion (301) may be adjacent to the fourth side portion (304) and the second side portion (302). The second side portion (302) may be adjacent to the first side portion (301) and the third side portion (303). The third side portion (303) may be adjacent to the second side portion (302) and the fourth side portion (304). The fourth side portion (304) may be adjacent to the third side portion (303) and the first side portion (301).

[0186] The housing (310) may include first to fourth corners (305, 306, 307, 308). The housing (310) may include first to fourth corners (305, 306, 307, 308) formed between the first to fourth side portions (301, 302, 303, 304). The first corner (305) and the third corner (307) may be formed opposite to each other. The second corner (306) and the fourth corner (308) may be formed opposite to each other.

[0187] The housing (310) may include a through hole (311), a drive unit coupling portion (312), and an upper coupling portion (313). The housing (310) may include a lower coupling portion. The housing (310) may include an inclined recess (315). The housing (310) may include a damper recess (330). The housing may include a bag-shaped portion (340). However, any one or more of the through hole (311), the drive unit coupling portion (312), the upper coupling portion (313), the lower coupling portion, the inclined recess (315), the damper recess (330), and the bag-shaped portion (340) may be omitted or changed from the housing (310). The housing (310) may also include an upper surface and an outer wall (334).

[0188] A through hole (311) may be formed on the housing (310). The through hole (311) may be formed at the interior of the housing (310). The through hole (311) may be formed to vertically pass through the housing (310). The bobbin (210) may be disposed in the through hole (311). The bobbin (210) may be movably disposed in the through hole (311). The through hole (311) may be partially formed to have a shape corresponding to the shape of the bobbin (210). The inner circumferential surface of the housing (310) forming the through hole (311) may be spaced apart from the outer circumferential surface of the bobbin (210). However, the inner surface of the housing (310) forming the through hole (311) may be provided with a stopper protruding inwardly to mechanically constrain the movement of the bobbin (210) along the optical axis direction.

[0189] The drive unit coupling portion (312) may be coupled by a drive magnet (320). The drive unit coupling portion (312) may be formed on the housing (310). The drive unit coupling portion (312) may be formed on the inner circumferential surface of the housing (310). In this case, it is advantageous that the drive magnet (320) provided on the drive unit coupling portion (312) electromagnetically interacts with the AF drive coil (220) provided on the inner side of the drive magnet (320). The drive unit coupling portion (312) may adopt a bottom open shape. In this case, the drive magnet (320) provided on the drive unit coupling portion (312) may advantageously electromagnetically interact with the OIS drive coil (422) provided at the lower side of the drive magnet (320). The drive unit coupling portion (312) may be formed as a recessed portion formed by allowing the inner circumferential surface of the housing (310) to be recessed outward. At this time, the drive unit coupling portion (312) may be formed in plurality. Meanwhile, each of the drive unit coupling parts (312) may accommodate a drive magnet (320). For example, the drive unit coupling part (312) may be divided into four (4). Each of the four drive unit coupling parts (312) may be provided with a drive magnet (320). For example, the drive unit coupling part (312) may be formed on a side surface of the housing (310). In another example, the drive unit coupling part (312) may be formed on a corner portion of the housing (310).

[0190] The upper coupling portion (313) may be coupled to the upper elastic member (510). The upper coupling portion (313) may be coupled to the outer portion (511) of the upper elastic member (510). The upper coupling portion (313) may be formed by protruding upward from the upper surface of the housing (310). For example, the lug on the upper coupling portion (313) may be coupled by being inserted into a recess or hole of the outer portion (511) of the upper elastic member (510). At this time, the lug of the upper coupling portion (313) may be fused while being inserted into the hole of the outer portion (511) to allow the upper elastic member (510) to be fixed between the upper surface of the housing (310) and the fused lug.

[0191] The lower coupling portion may be coupled to the lower elastic member (520). The lower coupling portion may be coupled to the outer portion (521) of the lower elastic member (520). The lower coupling portion may be formed by protruding downward from the lower surface of the housing (310). For example, the lug on the lower coupling portion may be coupled by being inserted into a recess or hole of the outer portion (521) of the lower elastic member (520). At this time, the lug of the lower coupling portion may be fused while being inserted into the hole of the outer portion (521) to allow the lower elastic member (520) to be fixed between the lower surface of the housing (310) and the fused lug.

[0192] The inclined recess (315) may be formed on a portion of the lower surface of the housing (310). The inclined recess (315) may be formed around the through hole (333). Therefore, even if the support member (600) is bent through the inclined recess (315), the contact between the support member (600) and the housing (310) may be minimized.

[0193] The damper recess (330) can be formed by allowing an area of ​​the lower surface of the leg (515) facing the upper elastic member (510) in the upper surface of the housing (310) to be recessed. The damper recess (330) can be provided with a first damper (910). The damper recess (330) can form a stepped portion with the outer wall portion (334). The damper recess (330) in this exemplary embodiment can be injected with the first damper (910). At this time, the first damper (910) can be injected only into the second recessed surface (332) of the damper recess (330). Alternatively, the first damper (910) can be injected into the first recessed surface (331) and the second recessed surface of the damper recess (330).

[0194] The damper recess (330) may be provided on an area facing the leg portion (515) and the coupling portion (514) of the upper elastic member (510) in the upper surface of the housing (310). The damper recess (330) may be provided with a first damper (910).

[0195] Fig.13 The damper recess (330) shown in the figure may be provided with only one wire, which is one of the elements of the supporting member (600). The damper recess (330) may include a first recess corresponding to the leg (515) of the upper elastic member (510) and a second recess corresponding to the coupling portion (514) of the upper elastic member (510). The first recess may include a first concave surface (331), such as Fig.13 The second recess may include a second recessed surface (332), such as Fig.13 As shown in . The first recess may be connected to the second recess. The length from the upper surface of the outer wall portion (334) to the bottom plate surface of the second recess (the second recessed surface 332) may be longer than the length from the upper surface of the outer wall portion (334) to the bottom plate surface of the first recess (the first recessed surface 331). A portion of the outer wall portion (334) of the housing (310) may form a first side wall of the first recess and the second recess.

[0196] The damper recess (330) may further include a third recess connected to the second recess. The third recess may include a first recessed surface (331), such as Fig.13 The second recess may be disposed between the first recess and the third recess, as shown in Fig.13As shown in . The bottom plate surface of the first recess (the first recessed surface 331) and the bottom plate surface of the third recess (the first recessed surface 331) may be provided on both sides of the second recess. A portion of the outer wall portion (334) of the housing (310) may form a second side wall of the second recess and the third recess.

[0197] That is, a portion of the outer wall portion (334) of the housing (310) may include the first side wall and the second side wall of the first recess, the second recess, and the third recess. The first recess and the second recess may be arranged on the upper side of the third recess. At the same time, any one or more of the first side wall and the second side wall may include a fourth recess (needle injection recess 335). The fourth recess may be placed between the first recess and the second recess, and / or between the second recess and the third recess.

[0198] Fig.14 The damper recess (330) may be provided with two wires, which are elements of the support member (600). The damper recess (330) may include a first recess provided on the second coupling portion (5022), a second recess provided on the third coupling portion (5023), and a third recess disposed between the first recess and the second recess. A portion of the outer wall portion (334) of the housing (310) may form a first side wall of the first recess and the second recess and a second side wall of the second recess and the third recess. That is, the outer wall portion (334) may include a first side wall and a second side wall formed to surround the first recess, the second recess, and the third recess.

[0199] In the present exemplary embodiment, the distance between the cover member (100) and the upper stopper of the housing (310) may be 80 μm. At this time, the distance between the leg (515) of the upper elastic member (510) and the first recessed surface (331) of the housing (310) may be 200 μm. In addition, the distance between the cover member (100) and the upper stopper of the housing (310) may be 70 μm to 90 μm. At this time, the distance between the leg (515) of the upper elastic member (510) and the first recessed surface (331) of the housing (310) may be 190 μm to 210 μm. The distance between the leg (515) of the upper elastic member (510) and the first recessed surface (331) of the housing (310) may be 1.5 to 4 times longer than the distance between the cover member (100) and the upper stopper of the housing (310). The distance between the leg portion (515) of the upper elastic member (510) and the first recessed surface (331) of the housing (310) may be 2 to 3 times longer than the distance between the cover member (100) and the upper stopper of the housing (310).

That is, the bag-shaped portion (340) can be used as a trap for collecting solder balls. In this exemplary embodiment, since the flux does not spread in all directions, defects caused by solder balls can be minimized.

[0214] In this exemplary embodiment, the bag-shaped portion (340) can contain an adhesive (bonding agent) to couple the plate (720) to the housing (310). With this structure, when the adhesive is applied to couple the plate (710) to the housing (310), the adhesive does not overflow.

[0303] Hereinafter, the operation of the camera module according to the present exemplary embodiment will be described.

[0304] First, the AF function of the camera module according to an exemplary embodiment will be described. When power is supplied to the AF drive coil (220), the AF drive coil (220) moves relative to the drive magnet (320) through the electromagnetic interaction between the AF drive coil (220) and the drive magnet (320). At this time, the bobbin (210) connected to the AF drive coil (220) can move integrally with the AF drive coil (220). That is, the bobbin (210) connected to the lens module moves relative to the housing (310) along the optical axis. In this exemplary embodiment, the movement of the bobbin (210) may cause the lens module to approach or move away from the image sensor, so that focusing control may be performed relative to the object by supplying power to the AF drive coil (220). At the same time, the focusing control may be automatically performed in response to the distance to the object.

[0305] Meanwhile, in the camera module according to the present exemplary embodiment, AF feedback control can be performed to achieve a more accurate AF function. The first sensor (710) provided on the housing (310) can detect the magnetic field of the sensing magnet (730) provided on the bobbin (210). As a result, when the bobbin (210) performs movement relative to the housing (310), the amount of magnetic field detected from the first sensor can be changed. The first sensor (710) can detect the amount of movement of the bobbin along the optical axis direction or the position of the bobbin (210) to transmit the detected value to the controller. The controller uses the received detection value to determine whether to perform additional movement of the bobbin (210). These types of processing are generated in real time, so that the AF function of the camera module according to the present exemplary embodiment can be performed more accurately through AF feedback control.

[0306] Now, the OIS function of the camera module according to an exemplary embodiment will be described. When power is supplied to the OIS drive coil (422), the drive magnet (320) moves relative to the OIS drive coil (422) through the electromagnetic interaction between the OIS drive coil (422) and the drive magnet (320). At this time, the housing (310) coupled to the drive magnet (320) can move integrally with the drive magnet (320). That is, the housing (310) moves in a horizontal direction (a direction perpendicular to the optical axis) relative to the base (430). However, at this time, the housing (310) may be tilted relative to the base (430). At the same time, the bobbin (210) can move integrally with the housing (310) relative to the horizontal movement of the housing (310). As a result, the movement of the housing (310) may cause the lens module coupled to the bobbin (210) to move relative to the image sensor in a direction parallel to the direction in which the image sensor is provided. That is, in the present exemplary embodiment, the OIS function may be performed by supplying power to the OIS driving coil ( 422 ).

[0307] At the same time, OIS feedback control can be performed to achieve a more accurate OIS function of the camera module according to the present exemplary embodiment. The second sensor (800) provided on the base (430) can detect the magnetic field of the driving magnet (320) provided on the housing (310). As a result, when the housing (310) performs a movement relative to the base (430), the amount of magnetic field detected by the second sensor can be changed. A pair of second sensors (800) can use the method to detect the movement of the housing (310) in the horizontal direction (x-axis and y-axis directions) to transmit the detection value to the controller. The controller uses the received detection value to determine whether to perform additional movement of the housing (310). These types of processing are generated in real time, so that the OIS function of the camera module according to the present exemplary embodiment can be more accurately performed through OIS feedback control.
