[0004] With the widespread adoption and use of various portable terminals, and the commercialization of wireless internet services, consumer demand related to portable terminals has diversified, and various add-on devices have been installed in portable terminals.

Recently, camera modules have emerged that have an autofocus function that automatically adjusts the focal length according to the distance to the object; or that have an optical image stabilization function that moves or tilts the lens module in a direction perpendicular to the optical axis to counteract vibrations (motion) generated in the image sensor by external forces.

[0006] However, in order to equip the camera module with autofocus and optical image stabilization, the following problems exist: the manufacturing process of the camera module becomes more complicated and the price increases due to the increased number of components and complex coupling relationships.

[0064] In the following description, some embodiments of the invention will be described with reference to the exemplary accompanying drawings. When describing the reference numerals for components in the drawings, the same components will be represented by the same reference numerals whenever possible, even if shown in other drawings. Furthermore, when describing embodiments of the invention, detailed descriptions of related well-known configurations or functions will be omitted if it is determined that such detailed descriptions would hinder understanding of the embodiments of the invention.

[0065] In describing the components of embodiments of the present invention, terms such as first, second, A, B, (a), and (b) may be used. These terms are intended only to distinguish a component from other components, and they do not limit the nature, order, or sequence of the components. When a component is described as being “connected,” “coupled,” or “joined” to another component, the component may be directly connected, coupled, or joined to the other component; however, it should be understood that another element may be “connected,” “coupled,” or “joined” between components.

[0066] The term "optical axis direction" used below is defined as the optical axis direction of the lens module in the state of being coupled with the lens drive device. On the other hand, "optical direction" can be used interchangeably with "vertical direction", "vertical direction", "z-axis direction", etc.

[0067] The term "autofocus function" as used below is defined as the function of automatically focusing on an object by moving the lens along the optical axis according to the distance to the object, thereby obtaining a clear image of the object on the image sensor. "Autofocus" can be used interchangeably with "AF (Autofocus)".

[0068] The “image stabilization function” used below is defined as the function of moving or tilting the lens module in a direction perpendicular to the optical axis to counteract vibrations (motions) generated in the image sensor by external forces. Also, “image stabilization” can be used interchangeably with “OIS (Optical Image Stabilization)”.

[0069] The first corner C1-1 of the housing, the first corner C2-1 of the substrate, the first corner C3-1 of the base, and the first corner C4-1 of the supporting elastic member can be positioned to correspond vertically. Additionally, the second corner C1-2 of the housing, the second corner C2-2 of the substrate, the second corner C3-2 of the base, and the second corner C4-2 of the supporting elastic member can be positioned to correspond vertically. Furthermore, the third corner C1-3 of the housing, the third corner C2-3 of the substrate, the third corner C3-3 of the base, and the third corner C4-3 of the supporting elastic member can be positioned to correspond vertically. Finally, the fourth corner C1-4 of the housing, the fourth corner C2-4 of the substrate, the fourth corner C3-4 of the base, and the fourth corner C4-4 of the supporting elastic member can be positioned to correspond vertically.

[0070] The configuration of the optical device according to this embodiment will be described below. The optical device according to this embodiment includes, but is not limited to, handheld phones, mobile phones, smartphones, portable smart devices, digital cameras, laptops, digital broadcast terminals, personal digital assistants (PDAs), portable multimedia players (PMPs), navigation devices, etc. Any device for capturing images or photographs can be used. The optical device according to this embodiment may include a main body (not shown), a display panel (not shown) disposed on one side (a surface) of the main body for displaying information, and a camera module 10 disposed inside the main body for capturing images or photographs. The camera module 10 is electrically connected to the display panel, thereby allowing the images or pictures captured by the camera module 10 to be reproduced on the display panel.

[0071] In the following description, the configuration of the camera module according to this embodiment will be described with reference to the accompanying drawings. Figure 1 This is a perspective view showing the camera module of this embodiment; Figure 2 This is a cross-sectional view of the camera module of this embodiment, taken along line A-A'; Figure 3 This is a cross-sectional view of the camera module of this embodiment, taken along line B-B'.

[0072] Although the accompanying drawings show a camera module equipped with the lens drive device 3000 of the third embodiment, it can be inferred that it can be applied to camera modules equipped with the lens drive devices 1000, 2000, 4000 and 5000 of the first, second, fourth and fifth embodiments.

[0073] The camera module in this embodiment may include a lens module 1, an infrared cut-off filter 4, a main substrate 2, an image sensor 3, a control unit (not shown), and lens driving devices 1000, 2000, 3000, 4000, and 5000.

[0074] Lens module 1 may include lenses and a lens barrel. Lens module 1 may include one or more lenses (not shown) and a lens barrel housing the one or more lenses. However, one configuration of lens module 1 is not limited to a lens barrel, and any structure can be used as long as the retainer structure can support one or more lenses. Lens module 1 may be coupled to lens drive devices 1000, 2000, 3000, 4000, and 5000 to move together with them. As an example, lens module 1 may be disposed inside the spool 400 of lens drive devices 1000, 2000, 3000, 4000, and 5000. In this case, the inner circumferential surface of lens module 1 and spool 400 may contact each other. As an example, lens module 1 may be threadedly coupled to the spool 400 of lens drive devices 1000, 2000, 3000, 4000, and 5000. The lens module 1 can be coupled to the spool 400 of the lens drive devices 1000, 2000, 3000, 4000 and 5000 by an adhesive (not shown). At the same time, light passing through the lens module 1 can illuminate the image sensor 3.

[0075] An infrared cut-off filter 4 can block light in the infrared region from incident on the image sensor 3. As an example, the infrared cut-off filter 4 can be located between the lens module 1 and the image sensor 3. The infrared cut-off filter 4 can be located in a retainer member (not shown) separately from the base 910. However, the infrared cut-off filter 4 can be installed in a hole formed in the central portion of the base 910. As an example, the infrared cut-off filter 4 can be formed of a film material or a glass material. As an example, the infrared cut-off filter 4 can be formed by coating an infrared cut-off coating material onto a plate-shaped optical filter (e.g., a cover glass) to protect the image pickup surface or the cover glass.

[0076] The main substrate 2 can be a printed circuit board (PCB). The main substrate 2 can support lens driving devices 1000, 2000, 3000, 4000, and 5000. An image sensor 3 can be mounted on the main substrate 2. As an example, the image sensor 3 can be located inside the upper surface of the main substrate 2, and a sensor holder (not shown) can be located outside the upper surface of the main substrate 2. The lens driving devices 1000, 2000, 3000, 4000, and 5000 can be located above the sensor holder. Alternatively, the lens driving devices 1000, 2000, 3000, 4000, and 5000 can be located outside the upper surface of the main substrate 2, and the image sensor 3 can be located inside the upper surface of the main substrate 2. With this structure, light passing through the lens module 1 housed within the lens driving devices 1000, 2000, 3000, 4000, and 5000 can illuminate the image sensor 3 mounted on the main substrate 2. The main substrate 2 can supply power to the lens driving devices 1000, 2000, 3000, 4000 and 5000. At the same time, the control unit for controlling the lens driving devices 1000, 2000, 3000, 4000 and 5000 can be located on the main substrate 2.

[0077] Image sensor 3 can be mounted on main substrate 2. Image sensor 3 can be positioned such that its optical axis coincides with lens module 1. Thus, image sensor 3 can capture light passing through lens module 1. Image sensor 3 can output the illuminated light as an image. For example, image sensor 3 can be a charge-coupled device (CCD), metal-oxide-semiconductor (MOS), CPD, and CID. However, the type of image sensor 3 is not limited to these.

[0078] The control unit can be mounted on the main substrate 2. The control unit can be located outside the lens drive devices 1000, 2000, 3000, 4000, and 5000. However, the control unit can also be located inside the lens drive devices 1000, 2000, 3000, 4000, and 5000. The control unit can control the direction, intensity, amplitude, etc., of the current supplied to each component of the lens drive devices 1000, 2000, 3000, 4000, and 5000. The control unit can control the lens drive devices 1000, 2000, 3000, 4000, and 5000 to perform at least one of the autofocus function and optical image stabilization function of the camera module 10. That is, the control unit can control the lens drive devices 1000, 2000, 3000, 4000, and 5000 to move the lens module 1 along the optical axis, or to move or tilt the lens module 1 in a direction perpendicular to the optical axis.

[0079] Furthermore, the control unit can perform feedback control for autofocus and optical image stabilization. More specifically, the control unit receives the position of the spool 400 or housing 200 detected by the sensor 940 to control the power or current applied to the first coil 500 to the second coil 930, thereby providing precise autofocus and image stabilization.

[0080] The lens driving device of this embodiment will be described below. The lens driving devices 1000, 2000, 3000, 4000, and 5000 of this embodiment can perform an autofocus function (AF function) by moving the spool 400 along the optical axis direction (vertical direction) due to the electromagnetic interaction between the magnet 300 and the first coil 500. In this case, a driving force is provided to the spool 400 by the electromagnetic interaction between the magnet 300 and the first coil 500, and the spool 400 can move in the vertical direction. Furthermore, in the lens driving devices 1000, 2000, 3000, 4000, and 5000 of this embodiment, the housing 200 moves in a direction perpendicular to the optical axis direction or tilts due to the electromagnetic interaction between the magnet 300 and the second coil 930 to perform optical image stabilization (OIS). In this case, a driving force can be provided to the housing 200 by the electromagnetic interaction between the magnet 300 and the second coil 930.

[0081] The lens driving device of this embodiment can have a first embodiment, a second embodiment, a third embodiment, a fourth embodiment, and a fifth embodiment. In the first, second, and third embodiments, the position sensor 980 is omitted. In the fourth and fifth embodiments, the position sensor 980 is present. The position sensor 980 can detect the position of the spool 400. Therefore, the lens driving devices 4000 and 5000 of the fourth and fifth embodiments can feed back the position information of the spool 400, and based on this, a precise autofocus function can be performed.

[0082] First, the lens driving devices 1000, 2000, and 3000 in the first, second, and third embodiments will be described. In the lens driving device 1000 of the first embodiment, the supporting elastic member 800 is omitted (see...). Figure 4 In the lens driving device 2000 of the second embodiment, the lower elastic member 700 is omitted (see [link]). Figure 5 In the third embodiment, the lens driving device 3000 includes both a lower elastic member 700 and a supporting elastic member 800 (see [reference]). Figure 6 ).

[0083] First, the lens driving device 1000 of the first embodiment will be described with reference to the accompanying drawings. Figure 4 This is an exploded perspective view showing the lens driving device of the first embodiment. Figure 7This is a perspective view showing the cover applied to the first embodiment.

Figure 12 This is a plan view showing the lower elastic member and base unit applied to the first embodiment.

That is, the second terminal portion 923 of the first substrate 920 may be exposed to the outside through the fourth recess 151 of the fourth side plate 150.

[0094] In the following text, reference will be made to Figure 8Describe housing 200. Housing 200 may have a hollow shape with holes formed in the optical axis direction. The bobbin 400 and the first coil 500 may be housed within housing 200. An upper elastic member 600 may be disposed above housing 200. A lower elastic member 700 may be disposed below housing 200. Housing 200 may be upwardly spaced from base unit 900 via the lower elastic member 700. Magnet 300 may be located within housing 200. In this case, magnet 300 may be positioned facing the first coil 500 and the second coil 930, respectively.

[0095] The housing 200 and the spool 400 can be connected by the upper elastic member 600 and the lower elastic member 700. In this case, the housing 200 and the spool 400 can be elastically connected by the upper elastic member 600 and the lower elastic member 700. The spool 400 can move in the optical axis direction (vertical direction and up-down direction) by the elastic action of the upper elastic member 600 and the lower elastic member 700.

[0096] The housing 200 and the base unit 900 can be connected via the lower elastic member 700. In this case, the housing 200 and the base unit 900 can be elastically connected via the lower elastic member 700. The housing 200 can be elastically supported by the lower elastic member 700. The housing 200 can move or tilt in a direction perpendicular to the optical axis through the elastic action of the lower elastic member 700.

[0097] The housing 200 can receive a driving force through the electromagnetic interaction between the magnet 300 and the second coil 930. The housing 200 can then move or tilt in a direction perpendicular to the optical axis using this driving force. In this configuration, the spool 400 and lens module 1 can move integrally with the housing 200 to perform optical image stabilization (OIS) functionality.

[0098] The housing 200 may include a first side portion 210, a second side portion 220, a third side portion 230, a fourth side portion 240, a first corner C1-1, a second corner C1-2, a third corner C1-3, and a fourth corner C1-4.

[0099] The first side portion 210 and the third side portion 230 can face each other when the magnet 300, the spool 400, and the first coil 500 are inserted between them (the third side portion is opposite to the first side portion, and vice versa). The second side portion 220 and the fourth side portion 240 can face each other when the magnet 300, the spool 400, and the first coil 500 are inserted between them (the fourth side portion is opposite to the second side portion, and vice versa). The first side portion 210 and the third side portion 230 can be connected via the second side portion 220 and the fourth side portion 240, and vice versa. The first side portion 210 and the third side portion 230 can be configured to be parallel to each other. The second side portion 220 and the fourth side portion 240 can be configured to be parallel to each other.

[0100] The first corner C1-1 of the housing 200 may be located between the first side portion 210 and the second side portion 220. The second corner C1-2 of the housing 200 may be located between the second side portion 220 and the third side portion 230. The third corner C1-3 of the housing 200 may be located between the third side portion 230 and the fourth side portion 240.

[0101] The first corner C1-1 of the housing 200 can be located among multiple corners of the first substrate 920 and the base 910, corresponding to the position (closest to) the first corner C2-1 of the first substrate 920 and the first corner C3-1 of the base 910. The second corner C1-2 of the housing 200 can be located among multiple corners of the first substrate 920 and the base 910, corresponding to the position (closest to) the second corner C2-2 of the first substrate 920 and the second corner C3-2 of the base 910.

[0102] The first corner C1-1 of the housing 200 may include a first receiving portion, which is recessed from the inner surface toward the outer surface. The second corner C1-2 of the housing 200 may include a second receiving portion 221, which is recessed from the inner surface toward the outer surface. The third corner C1-3 of the housing 200 may include a third receiving portion 231, which is recessed from the inner surface toward the outer surface. The fourth corner C1-4 of the housing 200 may include a fourth receiving portion 241, which is recessed from the inner surface toward the outer surface.

[0103] The outer end (at least a portion) of the first stop 411 of the spool 400 may be disposed in the first receiving portion 211. The outer end (at least a portion) of the second stop 421 of the spool 400 may be disposed in the second receiving portion 221. The outer end (at least a portion) of the third stop 431 of the spool 400 may be disposed in the third receiving portion 231. The outer end (at least a portion) of the fourth stop 441 of the spool 400 may be disposed in the fourth receiving portion 241.

[0104] When the spool 400 rotates due to an unexpected external force, the first to fourth stoppers 411, 421, 431 and 441 contact the housing 200 at the first to fourth receiving portions 211, 221, 231 and 241, thereby preventing the spool 400 from rotating.

[0105] The first magnet 310 can be disposed inside the first side portion 210. The second magnet 320 can be disposed inside the second side portion 220. The third magnet 330 can be disposed inside the third side portion 230. The fourth magnet 340 can be disposed inside the fourth side portion 240.

[0106] The first side portion 210 may include a first stop block 212 projecting inward from an inner surface. The first stop block 212 may be located above the first magnet 310. The first stop block 212 may be formed by a pair of members spaced apart from each other in the width direction of the first side portion 210. The fifth stop member 412 of the spool 400 may be spaced upward on the first stop block 212.

[0107] The second side portion 220 may include a second stop block 222 projecting inward from its inner surface. The second stop block 222 may be located above the second magnet 320.

[0108] The third side portion 230 may include a third stop block 232 protruding inward from the inner surface. The third stop block 232 may be located above the third magnet 330. The third stop block 232 may be formed as a pair of members spaced apart from each other in the width direction of the third side portion 210. The seventh stop member 432 of the spool 400 may be spaced upward on the third stop block 232.

[0109] The fourth side portion 240 may include a fourth stop block 242 projecting inward from its inner surface. The fourth stop block 242 may be located above the fourth magnet 340. The fourth stop block 242 may be formed as a pair of members spaced apart from each other in the width direction of the fourth side portion 240. The eighth stop member 442 of the spool 400 may be spaced upward on the fourth stop block 242.

[0110] When the spool 400 moves downward, the fifth to eighth stops 412, 422, 432 and 442 will contact the first to fourth stops 212, 222, 232 and 242, thereby blocking the downward movement of the spool 400.

[0111] Multiple bosses may protrude from the upper and lower surfaces of the housing 200 and be inserted into multiple holes in the upper elastic member 600 and the lower elastic member 700, respectively.

[0112] In the following text, reference will be made to Figure 8 Describe magnet 300. Magnet 300 can be disposed within housing 200. Magnet 300 can be positioned facing first coil 500. Magnet 300 can electromagnetically interact with first coil 500 to provide driving force to coil 400 (auto-focusing function). Magnet 300 can be positioned facing second coil 930. Magnet 300 can electromagnetically interact with second coil 930 to provide driving force to housing 200 (optical image stabilization function).

[0113] Magnet 300 may include a first magnet 310, a second magnet 320, a third magnet 330, and a fourth magnet 340. The first magnet 310, second magnet 320, third magnet 330, and fourth magnet 340 may be in the form of flat plates. The first magnet 310 may be coupled to the inner surface of the first side portion 210 via adhesive. The second magnet 320 may be coupled to the inner surface of the second side portion 220 via adhesive. The third magnet 330 may be coupled to the inner surface of the third side portion 230 via adhesive. The fourth magnet 340 may be coupled to the inner surface of the fourth side portion 240 via adhesive.

[0114] The first magnet 310, the second magnet 320, the third magnet 330, and the fourth magnet 340 can face the first coil 500. The first magnet 310 can face the 2-1 coil 932 of the second coil 930.

The fourth magnet 340 can face the 2-4 coil 935 of the second coil 930.

[0115] In the following text, reference will be made to Figure 9 Describe the spool 400. The spool 400 may have a hollow shape with holes formed in the optical axis direction. The spool 400 may be fitted with a lens module 1. In this case, the lens module 1 may be disposed in the spool 400. The spool 400 may be fitted with a first coil 500. In this case, the first coil 500 may be disposed on the outer surface (outer peripheral surface) of the spool 400.

[0116] The spool 400 can be disposed within the housing 200. The upper elastic member 600 can be disposed on the upper side of the spool 400. The lower elastic member 700 can be disposed on the lower side of the spool 400.

[0117] The spool 400 and the housing 200 can be connected by the upper elastic member 600 and the lower elastic member 700. In this case, the spool 400 and the housing 200 can be elastically connected by the upper elastic member 600 and the lower elastic member 700. The spool 400 can move in the optical axis direction due to the elastic action of the upper elastic member 600 and the lower elastic member 700.

[0118] The spool 400 can receive a driving force through the electromagnetic interaction between the first coil 500 and the magnet 300. The spool 400 can move along the optical axis using this driving force. The spool 400 can also move along the optical axis in both directions (upper and lower). In this configuration, the lens module 1 can move integrally with the spool 400 along the optical axis to perform an autofocus function (AF function).

[0119] Multiple bosses inserted into the multiple holes of the upper elastic member 600 and the lower elastic member 700 can protrude from the upper and lower surfaces of the spool 400.

[0120] The spool 400 may include first to eighth stops 411, 421, 431, 441, 412, 422, 432, and 442. These stops may protrude outward from the outer periphery of the spool 400. The stops 411, 421, 431, 441, 412, 422, 432, and 442 may be disposed on the first coil 500. These stops may be spaced upward from the first coil 500. The stops 411, 421, 431, 441, 412, 422, 432, and 442 may block rotational movement of the spool 400. The fifth to eighth stops 412, 422, 432 and 442 can prevent the downward movement of the spool 400. In addition, a protrusion can be formed protruding upward from the upper surface of the spool 400, and the upper plate 110 of the cover 100 can be contacted to prevent the upward movement of the spool 400.

[0121] In the following text, reference will be made to Figure 9The first coil 500 is described. The first coil 500 may be a coil assembly wound on the outer peripheral surface of the coil 400. The first coil 500 may be positioned facing the magnet 300. The first coil 500 may be electrically connected to the lower elastic member 700. For this purpose, one end and the other end of the first coil 500 may be soldered (solder bonded) to the 1-1 coupling portion 711 and the 1-2 coupling portion 712 of the lower elastic member 700, respectively. The first coil 500 may receive current (electricity) from the first substrate 920 through the lower elastic member 700. That is, the first substrate 920 may apply electricity (current) to the first coil 500. In this case, the wavelength, intensity, direction, etc., of the current supplied to the first coil 500 may be controlled by the control unit of the camera module 10.

[0122] In the following text, reference will be made to Figure 9 The upper elastic member 600 is described. The upper elastic member 600 supplements the elastic force of the lower elastic member 700 and can be omitted. The upper elastic member 600 can be in the form of a leaf spring. The upper elastic member 600 can be disposed on the housing 200 and the spool 400. The upper elastic member 600 can be coupled to the upper surface of the housing 200 and the upper surface of the spool 400, respectively. The upper elastic member 600 can elastically connect the housing 200 and the spool 400. The upper elastic member 600 can elastically support the spool 400.

[0123] The upper elastic member 600 may include an inner elastic portion 610, an outer elastic portion 620, and a connecting elastic portion 630. The inner elastic portion 610 may be disposed on the bobbin 400 and coupled to the upper surface of the bobbin 400. The outer elastic portion 620 may be disposed on the housing 200 and coupled to the upper surface of the housing 200. The connecting elastic portion 630 may be disposed between the inner elastic portion 610 and the outer elastic portion 620. There may be four connecting elastic portions 630. The four connecting elastic portions 630 may be spaced apart from each other. Curvature may be formed in various directions within the connecting elastic portions 630.

[0124] In the following text, reference will be made to Figure 9The lower elastic member 700 is described. The lower elastic member 700 can be in the form of a leaf spring. The lower elastic member 700 can be disposed on the underside of the housing 200 and the bobbin 400. The lower elastic member 700 can be coupled to the lower surface of the housing 200 and the lower surface of the bobbin 400, respectively. Furthermore, the lower elastic member 700 can be coupled to the base unit 900. That is, the lower elastic member 700 elastically connects the housing 200 and the bobbin 400 to elastically support the bobbin 400, and simultaneously elastically connects the housing 200 and the base unit 900 to elastically support the housing 200. The housing 200 can be positioned such that it is upwardly (suspended) spaced from the base unit 900 by the lower elastic member 700. The lower elastic member 200 can be coupled to the first base plate 920 of the base unit 900, or it can be coupled to the base 910 of the base unit 900.

[0125] The lower elastic member 700 can be electrically connected to the first coil 500. The lower elastic member 700 can also be electrically connected to the 1-1 substrate 920. When the lower elastic member 700 is coupled to the 1-1 substrate 920, it can directly contact the 1-1 substrate 920 for electrical connection. When the lower elastic member 700 is coupled to the base 910, it can be electrically connected to the 1-1 substrate 920 through a separate conductive member. The first coil 500 can receive current (electricity) from the 1-1 substrate 920 through the lower elastic member 700.

[0126] The lower elastic member 700 may include a first coupling portion 710, a second coupling portion 720, a first connecting portion 730, and a second connecting portion 740. The lower elastic member 700 may be divided into a first lower elastic member and a second lower elastic member spaced apart from each other. That is, the lower elastic member 700 may be formed by a pair of spaced-apart members. When electricity is applied to the first coil 500, one of the first and second lower elastic members may form a positive (+) conductive line, and the other may form a negative (-) conductive line. Since the positive (+) and negative (-) conductive lines are spaced apart from each other, no short circuit occurs.

[0127] The first coupling portion 710 may be located inside the second coupling portion 720. The first coupling portion 710 may be located below the spool 400. The first coupling portion 710 may be coupled to the bottom surface of the spool 400. The first coupling portion 710 may be electrically connected to the first coil 500. A plurality of holes may be formed in the first coupling portion 710, and a plurality of bosses protruding from the bottom surface of the spool 400 may be inserted (set) in the holes.

[0128] The first coupling portion 710 may include a 1-1 coupling portion 711 and a 1-2 coupling portion 712 spaced apart from each other. In this case, the 1-1 coupling portion 710 may be located on the first lower elastic member, and the 1-2 coupling portion 712 may be located on the second lower elastic member. One end of one side of the first coil 500 may be soldered to the 1-1 coupling portion 711 for electrical connection. The other end of the first coil 500 may be soldered to the 1-2 coupling portion 712 for electrical connection. Therefore, the first coupling portion 711 may be electrically connected to the first coil 500.

[0129] The second coupling portion 720 may be located outside the first coupling portion 710. The second coupling portion 720 may be located below the housing 400. The second coupling portion 720 may be coupled to the bottom surface of the housing 400. Multiple holes may be formed in the second coupling portion 720, and multiple bosses protruding from the bottom surface of the housing 400 may be inserted (set) in the holes.

[0130] The second coupling portion 720 may include a 2-1 coupling portion 721 and a 2-2 coupling portion 722 spaced apart from each other. In this case, the 2-1 coupling portion 721 may be located on the first lower elastic member, and the 2-2 coupling portion 722 may be located on the second lower elastic member.

[0131] The first connecting portion 730 may be located between the first coupling portion 710 and the second coupling portion 720. The first connecting portion 730 can elastically connect the first coupling portion 710 and the second coupling portion 720. That is, the first connecting portion 730 can elastically connect the housing 200 and the spool 400. The first connecting portion 730 can extend from corners C1-1, C1-2, C1-3, and C1-4 of the housing 200 to the first coupling portion 710. In this case, the first connecting portion 730 can be bent in various directions. This is to increase the elastic force.

[0132] The first connecting portion 730 may include a 1-1 connecting portion 731, a 1-2 connecting portion 732, a 1-3 connecting portion 733, and a 1-4 connecting portion 734 spaced apart from each other. The 1-1 connecting portion 731 and the 1-2 connecting portion 732 may be located on the first lower elastic member, and the 1-3 connecting portion 733 and the 1-4 connecting portion 734 may be located on the second lower elastic member.

[0133] The 1-1 connecting portion 731 can extend from the first corner C1-1 of the housing 200 to the 1-1 coupling portion 711. The 1-2 connecting portion 732 can extend from the second corner C1-2 of the housing to the 1-1 coupling portion 711. The first connecting portion 733 can extend from the third corner C1-3 of the housing 200 to the 1-2 coupling portion 712. The first to fourth connecting portions 734 can extend from the fourth corner C1-4 of the housing 200 to the 1-2 coupling portion 712.

[0134] The second connecting portion 740 may be located outside the second coupling portion 720. The second connecting portion 740 may elastically connect the housing 200 and the base unit 900. Therefore, the lower elastic member 700 may elastically support the housing 200.

[0135] More specifically, the second connecting portion 740 can elastically connect the second coupling portion 720 and the first substrate 920. Therefore, the lower elastic member 700 can be coupled to the first substrate 920. At the same time, the second connecting portion 740 can electrically connect the lower elastic member 700 and the first substrate 920.

[0136] Conversely, the second connecting portion 740 can elastically connect the second coupling portion 720 and the base 910. Therefore, the lower elastic member 700 can be coupled to the base 910. In this case, the lower elastic member 700 and the first substrate 920 can be electrically connected through separate conductive members.

[0137] The height of the portion of the second connecting part 740 located in the housing 200 (one side end) can be greater than the height of the portion of the second connecting part 740 located in the first substrate 920 or base 910 (the other side end). That is, the second connecting part 740 can be tilted upwards from the first substrate 920 or base 910 toward the housing 200. This is to provide a biasing force to the housing 200. Furthermore, the housing 200 can be positioned such that it is upwardly (suspended) spaced from the base unit 900.

[0138] The second connecting portion 740 may include a second-first connecting portion 741, a second-second connecting portion 742, a second-third connecting portion 743, and a second-fourth connecting portion 744 spaced apart from each other. The second-first connecting portion 741 and the second-second connecting portion 742 may be located in the first lower elastic member. The second-third connecting portion 743 and the second-fourth connecting portion 744 may be located in the second lower elastic member.

[0139] The second-first connecting portion 741 extends from the first corner C1-1 of the housing 200 to the first corner C2-1 of the first substrate 920. The second-first connecting portion 741 can be coupled to the first corner C2-1 of the first substrate 920. The second-second connecting portion 742 extends from the second corner C1-2 of the housing 200 to the second corner C2-2 of the first substrate 920. The second-second connecting portion 742 can be coupled to the second corner C2-2 of the first substrate 920. The second-third connecting portion 743 extends from the third corner C1-3 of the housing 200 to the third corner C2-3 of the first substrate 920. The second-third connecting portion 743 can be coupled to the third corner C2-3 of the first substrate 920. The second-fourth connecting portion 744 extends from the fourth corner C1-4 of the housing 200 to the fourth corner C2-4 of the first substrate 920. The second-fourth connecting portion 744 can be coupled to the fourth corner C2-4 of the substrate 920. In this configuration, at least one of the second-first connecting portion 741 and the second-second connecting portion 742 can be electrically connected to the first substrate 920, and at least one of the second-third connecting portion 743 and the second-fourth connecting portion 744 can be electrically connected to the first substrate 920. A circuit for applying current (electricity) to the first coil 500 can be formed using the first coil 500, the lower elastic member 700, and the first substrate 920.

[0140] However, as described above, the second connecting portion 740 may extend to the base 910 instead of the first substrate 920. In this case, the second-first connecting portion 741 may extend from the first corner C1-1 of the housing 200 to the first corner C3-1 of the base 910. The second-first connecting portion 741 may be coupled to the first corner C3-1 of the base 910. The second-second connecting portion 742 may extend from the second corner C1-2 of the housing 200 to the second corner C3-2 of the base 910. The second-second connecting portion 742 may be coupled to the second corner C3-2 of the base 910. The second-third connecting portion 743 may extend from the third corner C1-3 of the housing 200 to the third corner C3-3 of the base 910. The second-third connecting portion 743 may be coupled to the third corner C3-3 of the base 910. The second-fourth connecting portion 744 may extend from the fourth corner C1-4 of the housing 200 to the fourth corner C3-4 of the base 910. The second-fourth connecting portion 744 can be coupled to the fourth corner C3-4 of the base 910. The lower elastic member 700 can be connected to the second substrate 930.

[0141] In the following text, reference will be made to Figure 10 , Figure 11 and Figure 12Describe the base unit 900. The base unit 900 can be disposed below the cover 100, housing 200, magnet 300, coil 400, first coil 500, upper elastic member 600, and lower elastic member 700. The base unit 900 can support the cover 100. The lower ends of the four side plates 120, 130, 140, and 150 of the cover 100 can be fixed to the base unit 900.

[0142] The base unit 900 can close the lower opening of the cover 100. The housing 200, magnet 300, spool 400, first coil 500, upper elastic member 600 and lower elastic member 700 can be accommodated in the space formed by the cover 100 and the base unit 900.

[0143] The base unit 900 may have a hole formed in its center. Therefore, light transmitted through the lens module 1 can be projected onto the image sensor 3 through the hole in the base unit 900.

[0144] The base unit 900 may include a base 910, a 1-1 substrate 920, a second substrate 930, a housing sensor 940, and a bearing 950.

The fourth corner C4-4 of the supporting elastic member 800 can be located at the position corresponding to the fourth corner C2-4 of the first substrate 920 among multiple corners of the base 910 (the closest position).

[0172] The first corner C4-1 and the fourth corner C4-4 of the supporting elastic member 800 can be located at the first support portion 811. The second corner C4-2 and the third corner C4-3 of the supporting elastic member 800 can be located at the second support portion 812.

[0173] The extension 820 can connect the support 810 and the first substrate 920.

[0174] The extension 820 can be electrically connected to the first substrate 920. However, the arrangement of the extension 820 is not limited to this. The extension 820 can connect the support 810 and the base 910. In this case, the extension 820 can be electrically connected to the first substrate 920 via a separate conductive member. The extension 820 may include a first extension 821, a second extension 822, a third extension 823, and a fourth extension 824. The first extension 821 and the fourth extension 824 may be located on the first support 811. The second extension 822 and the third extension 823 may be located at the second support 812.

[0175] The first extension 821 extends from the first corner C4-1 of the supporting elastic member 800 to the fourth corner C2-4 of the first substrate 920. The first extension 821 connects the first corner C4-1 of the first support portion 811 and the fourth corner C2-4 of the first substrate 920. The first extension 821 is electrically connected to the fourth corner C2-4 of the first substrate 920. The first extension 821 can tilt upwards from the first substrate 920 toward the supporting elastic member 800. Therefore, the first extension 821 can provide a biasing force to the first support portion 811. As a result, the first support portion 811 can support the housing 200 to suspend the housing 200 upwards.

[0176] The second extension 822 extends from the second corner C4-2 of the supporting elastic member 800 to the first corner C2-1 of the first substrate 920. The second extension 822 connects the second corner C4-2 of the second support portion 812 and the first corner C2-1 of the first substrate 920. The second extension 822 is electrically connected to the first corner C2-1 of the first substrate 920. The second extension 822 can be inclined upwards from the first substrate 920 toward the supporting elastic member 800. Therefore, the second extension 822 can provide a biasing force to the second support portion 812. As a result, the second support portion 812 can support the housing 200 to suspend the housing 200 upwards.

[0177] The third extension 823 extends from the first triangle C4-3 of the supporting elastic member 800 to the second corner C2-2 of the first substrate 920. The third extension 823 connects the first triangle C4-3 of the second support 812 and the second corner C2-2 of the first substrate 920. The third extension 823 is electrically connected to the second corner C2-2 of the first substrate 920. The third extension 823 can tilt upwards from the first substrate 920 toward the supporting elastic member 800. Therefore, the third extension 823 can provide a biasing force to the second support 812. As a result, the second support 812 can support the housing 200 to suspend the housing 200 upwards.

[0178] The fourth extension 824 extends from the fourth corner C4-4 of the supporting elastic member 800 to the triangle C2-3 of the first substrate 920. The fourth extension 824 connects the fourth corner C4-4 of the first support 811 and the triangle C2-3 of the first substrate 920. The fourth extension 824 is electrically connected to the triangle C2-3 of the first substrate 920. The fourth extension 824 can tilt upwards from the first substrate 920 toward the supporting elastic member 800. Therefore, the fourth extension 824 can provide a biasing force to the first support 811. As a result, the first support 811 can support the housing 200 to suspend the housing 200 upwards.

[0179] The extension directions of the first to fourth extensions 821, 822, 823, and 824 are advantageous structures for moving or tilting the housing 200 in a direction perpendicular to the optical axis. Furthermore, the first to fourth extensions 821, 822, 823, and 824 may have a wave-like structure that bends multiple times in various directions perpendicular to the optical axis.

[0180] The support elastic member 800 can be connected to the second substrate 930. The support elastic member 800 can be referred to as a "leaf spring" or "leaf elastic member".

[0181] In the lens driving device 2000 according to the second exemplary embodiment, the housing 200 can be elastically supported by the supporting elastic member 800. Additionally, the spool 400 can be elastically supported by the upper elastic member 600. In this case, the supporting elastic member 800 has a structure specifically for moving or tilting the housing 200 in a direction perpendicular to the optical axis, and the upper elastic member 600 has a structure specifically for moving the spool 400 in the optical axis direction, thereby stably supporting the housing 200 and the spool 400.

[0182] In the following description, the lens driving device 3000 of the third embodiment will be described with reference to the accompanying drawings. Figure 6 This is an exploded perspective view showing the lens driving device of the third embodiment. Figure 15 This is a plan view of the supporting elastic member, lower elastic member, and base unit applied in the third embodiment. In the lens driving device 3000 of the third embodiment, there is a lower elastic member 700 and a supporting elastic member 800. Furthermore, the technical features of the lens driving device 1000 of the first embodiment and the lens driving device 2000 of the second embodiment can be deduced and applied.

[0183] The lower elastic member 700 can be disposed above the supporting elastic member 800, and the supporting elastic member 800 can be disposed below the lower elastic member 700.

[0184] On the other hand, the lower elastic member 700 and the supporting elastic member 800 can be electrically connected. The second-first connecting portion 741 and the fourth extension portion 824 can contact each other at the first corner C2-1 of the first substrate 920 to be electrically connected. The second-second connecting portion 742 and the third extension portion 823 can contact each other at the second corner C2-2 of the first substrate 920 to be electrically connected. The second connecting portion 743 and the second extension portion 822 can contact each other at the third corner C2-3 of the first substrate 920 to be electrically connected. The second-fourth connecting portion 744 and the first extension portion 821 can be electrically connected by contacting the fourth corner C2-4 of the first substrate 920.

[0185] In this configuration, there can be a total of four conductive lines. First, the first coil 500 and the lower elastic member 700 can be electrically connected, and the lower elastic member 700 and the first substrate 920 can be electrically connected. In this configuration, the first substrate 920 can apply power (current) to the first coil 500 through the lower elastic member 700. Second, the first coil 500 and the supporting elastic member 800 can be electrically connected, and the supporting elastic member 800 and the first substrate 920 can be electrically connected. In this configuration, the first substrate 920 can apply power (current) to the first coil 500 through the supporting elastic member 800. Third, the first coil 500 and the lower elastic member 700 can be electrically connected to each other, the lower elastic member 700 and the supporting elastic member 800 can be electrically connected to each other, and the supporting elastic member 800 and the first substrate 920 can be electrically connected to each other. In this configuration, the first substrate 920 can sequentially apply power (current) to the first coil 500 through the supporting elastic member 800 and the lower elastic member 700. Fourth, the first coil 500 and the supporting elastic member 800 can be electrically connected, the supporting elastic member 800 and the lower elastic member 700 can be electrically connected, and the lower elastic member 700 and the first substrate 920 can be electrically connected to each other. In this case, the first substrate 920 can apply power (current) to the first coil 500 sequentially through the lower elastic member 700 and the supporting elastic member 800.

[0186] In the lens driving device 3000 of this embodiment, the housing 200 can be elastically supported by the lower elastic member 700 and the supporting elastic member 800. Additionally, the spool 400 can be elastically supported by the lower elastic member 700 and the upper elastic member 600. The supporting elastic member 800 and the lower elastic member 700 can complement each other to ensure an elastic support force on the housing 200, and the lower elastic member 700 and the upper elastic member 600 can complement each other to ensure a support force on the spool 400. Therefore, the housing 200 and the spool 400 can be stably supported.

[0187] The lens driving device 4000 of the fourth embodiment and the lens driving device 5000 of the fifth embodiment will be described below. In the fourth and fifth embodiments, a position sensor 980 is provided, which performs the autofocus function by detecting the position of the bobbin 400 and feeding it back, thereby improving the quality of the autofocus function.

[0188] First, the lens driving device 4000 of the fourth embodiment will be described with reference to the accompanying drawings. Figure 16 This is an exploded perspective view showing the lens driving device of the fourth embodiment; Figure 18 This is an exploded perspective view showing the spool, first coil, sensing magnet, and compensating magnet applied to the fourth embodiment; Figure 19 This is a perspective view showing the position sensor applied to the fourth embodiment; Figure 20 This is a perspective view showing the upper and lower elastic members applied in the fourth embodiment; Figure 21 The lower elastic member and base unit are from the fourth embodiment; Figure 22 This is a plan view showing the lower elastic member and base unit of the fourth embodiment; Figure 24 This is a plan view showing the lens drive device with the cover removed in the fourth embodiment.

[0189] Aside from the addition of a sensing magnet 960, a compensating magnet 970, and a position sensor 980, and differences in the shapes of the bobbin 400, the first coil 500, the upper elastic member 600, and the lower elastic member 700, the fourth embodiment may have essentially the same technical features as the first embodiment. Therefore, the technical characteristics of the lens driving device 1000 of the first embodiment can be inferred and applied to the lens driving device 4000 of the fourth embodiment.

[0190] In the spool 400, unlike the first embodiment, instead of the second stop 421, a sensing magnet receiving portion 423 can be formed inwardly from the outer peripheral surface of the spool 400 at this location. Furthermore, instead of the fourth stop 442, a compensating magnet receiving portion 443 can be formed inwardly from the outer peripheral surface of the spool 400 at this location. A sensing magnet 960 can be disposed in the sensing magnet receiving portion 423. A compensating magnet 970 can be disposed in the compensating magnet receiving portion 443.

[0191] The sensing magnet receiving portion 423 and the compensating magnet receiving portion 443 can be spaced upward from the coil 500. The sensing magnet receiving portion 423 and the compensating magnet receiving portion 443 can be configured not to face the driving magnet 300.

Furthermore, the technical features of the support elastic member 800 of the second and third embodiments can be deduced and applied to the support elastic member 800 of the fifth embodiment.
