A partition wall (310) may connect two sidewalls, each facing the other. The partition wall (310) may partition an inner space of the case (300) into a first space (301) and a second space (302). The partition wall (310) may divide the first space (301) and the second space (302) into equal sizes, and may also divide the first space (301) and the second space (302) into different sizes. The partition wall (310) may be integrally formed with the sidewall (320) of the case (300). The case (300) may be omitted together with the partition wall (310), and may be alternatively formed with a through hole. In this case, the first magnet (510) may be provided to the through-hole to divide the first space (301) and the second space (302). That is, the partition wall (310) may be omitted to allow the first magnet (510) to serve as the partition wall (310). In this case, the height of the first magnet (510) may coincide with the height of the housing (300).

The third magnet receiving part (350) and the third magnet (530) may be connected by an adhesive.

The spacer (360) may be formed upward and protruded from the upper surface of the sidewall (320) at the case (300). The spacer (360) may be formed to ensure an upper movement space where the bobbin (210, 220) is coupled to the first elastic member (710). That is, the spacer (360) may separate the upper surface of the sidewall (320) at the case 300 from the inner surface of the upper plate (101) at the cover member (100). That is, a discrete space (discrete space) between an upper surface of the sidewall (320) at the case (300) and an inner surface of the upper plate (101) at the cover member (100) may be used as a movable space of the first elastic member (710) and the bobbin (210, 220).

At this time, the first bobbin (210) may also move together with the first coil (410). The first coil (410) may receive power through the second elastic member (720). However, the present invention is not limited thereto, and the first coil (410) may also receive power from the first elastic member (710).

A shield plate (not shown) may be disposed between the two separated magnets. The shielding plate may remove a phenomenon of interaction between electromagnetic interaction with the first coil (410) and electromagnetic interaction with the second coil. That is, a shielding plate may be disposed between the first space (301) and the second space (302) to eliminate an influence phenomenon of the electromagnetic force of the first space (301) on the second space (302) or an influence phenomenon of the electromagnetic force of the second space (302) on the first space (301).

As shown in fig. 7, the inner surface of the second magnet (520) and the inner surface of the third magnet (530) may have different polarities from each other. For example, the inner surface of the second magnet (520) may have an N-pole, and the inner surface of the third magnet (530) may have an S-pole. At this time, the side surface of the second magnet (520) side of the first magnet (510) may have an N-pole, and the side surface of the third magnet (530) side of the first magnet (510) may have an S-pole. In contrast, the inner surface of the second magnet (520) may have an S-pole, and the inner surface of the third magnet (530) may have an N-pole. At this time, the side surface of the second magnet (520) side of the first magnet (510) may have an S-pole, and the side surface of the third magnet (530) side of the first magnet (510) may have an N-pole. In a modification, when the first magnet (510) is formed with two magnets by separation, both the first space (301) side and the second space (302) side may have an N-pole arranged on each inner side thereof.

The inner space formed by the coupling between the base (300) and the cover member (100) may be provided with elements such as the bobbin (210, 220) and the case (300). The base (600) may be arranged at a bottom side of a PCB (printed circuit board). An upper surface of the PCB disposed at the bottom side of the base (600) may be mounted with an image sensor (not shown). At this time, the number of image sensors may be 2, which is the same as the number of bobbins (210, 220) through which light introduced through lens modules coupled to the first bobbin (210) and the second bobbin (220), respectively, may be obtained by each image sensor. In this case, the image sensor on the first bobbin (210) side may be referred to as a first image sensor (not shown), and the image sensor on the second bobbin (220) side may be referred to as a second image sensor (not shown).

The base (600) may include a partition wall (630) between the first image sensor and the second image sensor, so that light introduced through the lens module coupled to the first bobbin (210) may reach only the first image sensor without allowing the light to reach the second image sensor. That is, the base (600) may include a partition wall (630) disposed between the first image sensor and the second image sensor, so that light introduced through the lens module coupled to the second bobbin (220) may reach only the second image sensor without allowing the light to reach the first image sensor.

The base (600) may be disposed at the bottom surface and have a partition wall (630) interposed between the first opening (610) and the second opening (620) and formed to protrude toward the bottom side. The partition wall (630) may extend from a corner of one side of the bottom surface at the base (600) to a corner of the other side at the base (600). With this configuration, it is possible to prevent light passing through a lens module coupled to the first bobbin (210) and light passing through a lens module coupled to the second bobbin (220) from interfering with each other or affecting an image sensor at the other side.

The lug (640) may be protrudingly formed with the same height as that of the partition wall (630) by surrounding the outer circumferential surface at the bottom surface of the base (600).

When the first coil (410) connected to the first bobbin (210) of the dual camera module according to the first exemplary embodiment of the present invention is supplied with power through the second elastic member (720), the first bobbin (210) may be moved in the optical axis direction to perform an auto-focus function. Further, when power is supplied to the second coil (420) connected to the second bobbin (220) through the third elastic member (730), the second bobbin (220) may be moved in the optical axis direction to perform an auto-focus function. That is, the first bobbin (210) and the second bobbin (220) may be independently driven.

The dual camera module according to the first exemplary embodiment of the present invention may include a first bobbin (210) and a second bobbin (220). The first bobbin (210) and the second bobbin (220) may be coupled with the lens module, respectively. At this time, the first bobbin (210) may provide a narrower viewing angle than the second bobbin (220), and the second bobbin (220) may provide a wider viewing angle than the first bobbin (210).

That is, the dual camera module according to the first exemplary embodiment of the present invention may obtain clear quality images of objects at a short distance and a long distance.

Hereinafter, the configuration of an optical apparatus according to a second exemplary embodiment of the present invention will be described.

The optical device may be a mobile phone, a smart phone, a portable smart device, a digital camera, a notebook (laptop), a PMP (portable multimedia player), and a navigation device. However, the present invention is not limited thereto, and any device capable of taking an image or a photograph may be referred to as an optical device.

The optical apparatus may include a main body (not shown), a display part (not shown) provided on the main body to display information, and a camera (not shown) provided on the main body to take an image of a photograph and having a camera module (not shown).

Now, hereinafter, a configuration of a camera module according to a second exemplary embodiment of the present invention will be described.

The camera module may include a lens driving apparatus (1000), a lens module (not shown), an IR (infrared cut filter (not shown)), a PCB (printed circuit board, not shown), an image sensor (not shown), and a controller (not shown). However, any one or more of the lens driving device (1000), the lens module (not shown), the IR cut filter, the PCB, the image sensor, and the controller may be omitted or changed.

The lens module may include one or more lenses (not shown) and a lens barrel accommodating the one or more lenses. However, one element of the lens module is not limited by the lens barrel, and any support structure capable of supporting one or more lenses would suffice. The lens module may move together with the lens driving device (1000) by being coupled to the lens driving device (1000). For example, the lens module may be coupled to the inside of the lens driving apparatus (1000). For example, the lens module may be screw-coupled with the lens driving device (1000). For example, the lens module may be coupled to the lens driving device (1000) using an adhesive. Meanwhile, light having passed through the lens module may be irradiated on the image sensor.

An infrared cut filter may be used to prevent light in the infrared region from entering the image sensor. For example, an infrared cut filter may be interposed between the lens module and the image sensor. The infrared cut filter may be provided to a bracket member (not shown) provided separately from the base (1600). However, the infrared cut filter may be installed at a hollow hole (1611) formed at the center of the base (1600). For example, the infrared ray cut filter may be formed of a film material or a glass material. Meanwhile, for example, the infrared cut filter may be formed by coating an infrared cut coating material on a plate-shaped optical filter such as an imaging plane protective cover glass or a cover glass.

The PCB (printed circuit board) may support the lens driving device (1600). The PCB may be mounted with an image sensor. For example, an upper inner side of the PCB may be provided with an image sensor, and an upper outer side of the PCB may be provided with a sensor holder (not shown). The upper side of the sensor holder may be provided with a lens driving device (1000). Alternatively, the upper outer side of the PCB may be provided with a lens driving device (1000), and the upper inner side of the PCB may be provided with an image sensor. With this structure, light having passed through the lens module accommodated inside the lens driving apparatus (1000) can be irradiated onto the image sensor mounted on the PCB. The PCB may supply power to the lens driving apparatus (1000). Meanwhile, the PCB may be provided with a controller to control the lens driving device (1000).

The image sensor may be mounted on a PCB. The image sensor may be disposed to match the lens module in terms of the optical axis, and the image sensor may obtain light that has passed through the lens module by this arrangement. The image sensor may output the irradiated light as an image. For example, the image sensor may be a CCD (charge coupled device), a MOS (metal oxide semiconductor), a CPD, and a CID. However, the type of the image sensor is not limited thereto.

The controller may be mounted on the PCB. The controller may be provided outside the lens driving apparatus (1000). However, the controller may be provided inside the lens driving device (1000). The controller may control the direction, intensity, and magnitude of the current supplied to each element of the lens driving apparatus (1000). The controller may perform any one of an AF function and an OIS function of the camera module by controlling the lens driving apparatus (1000). That is, the controller may move the lens module in the optical axis direction or tilt the lens module in a direction orthogonal to the optical axis direction by controlling the lens driving device (1000). Further, the controller may perform feedback control of the AF function and the OIS function.

The lens driving apparatus (1000) may include a cover member (1100), a bobbin (1200), a first driving part (1300), a housing (1400), a second driving part (1500), a base (1600), and a support member (1700, 1800). However, any one or more of the cover member (1100), the bobbin (1200), the first driving part (1300), the housing (1400), the second driving part (1500), the base (1600), and the support member (1700, 1800) may be omitted from the lens driving apparatus (1000).

The lens driving apparatus (1000) according to the second exemplary embodiment of the present invention may be applied to the dual camera module according to the first exemplary embodiment of the present invention. More specifically, the two lens driving devices (1000) according to the second exemplary embodiment of the present invention may be applied to a dual camera module. At this time, as explained in the first exemplary embodiment, the two housings (1400), the two base portions (1600), and the two cover members (1100) may be integrally formed in the two lens driving devices (1000) according to the second exemplary embodiment. However, the two lens driving devices (1000) may be independently disposed in parallel, with one spaced apart from the other. At this time, a shielding plate configured to shield electromagnetic force may be interposed between the two lens driving devices (1000).

The cover member (1100) may form an appearance of the lens driving apparatus (1000). The cover member (1100) may take the shape of a cube with an open bottom. However, the shape of the cover member 1100 of the present invention is not limited thereto. An inner space formed by the cover member (1100) and the base (1600) may be provided with the bobbin (1200), the first driving part (1300), the housing (1400), the second driving part (1500), and the support member (1700, 1800). With this configuration, the cover member (1100) can protect the internal element against external impact and at the same time prevent intrusion of external foreign matter.

For example, at least a portion of the cover member (1100) may be formed of a metal material. More specifically, the cover member (1100) may be formed of a metal plate. In this case, the cover member (1100) can prevent EMI (electromagnetic interference). That is, the cover member (1100) can prevent electric waves generated from the outside of the cover member (1100) from entering the inside of the cover member (1100). Further, the cover member (1100) can prevent electric waves generated from the inside of the cover member (1100) from being emitted to the outside of the cover member (1100). However, the material of the cover member (1100) is not limited thereto.

The cover member (1100) may include an upper plate (1101), an outer plate (1102), and an inner plate (1103). The cover member (1100) may include an upper plate (1101) forming an upper surface, an outer plate (1102) forming an outer surface, and an inner plate (1103) provided inside to face the outer plate (1102). The cover member (1100) may include an upper plate (1101) and an outer plate (1102) extending from an outer side to a bottom side of the upper plate (1101). The bottom end of the outer plate (1102) may be coupled to the base (1600). The inner panel (1103) may be formed by extending from the inside to the bottom side of the upper panel (1101). The inner panel (1103) may be received in an inner panel receiving groove (1260) of the bobbin (1200) to prevent the bobbin (1200) from rotating. That is, the inner plates (1103) and the bobbin (1200) forming the inner plate receiving groove (1260) may prevent the bobbin (1200) from rotating by allowing the bobbin (1200) to be locked. An inner panel (1103) may be formed at every four corner portions. However, the present invention is not limited thereto. The width of the inner panel (1103) may correspond to the width of the inner panel receiving groove (1260) or may be less than the width of the inner panel receiving groove (1260).

The cover member (1100) may include an opening. The cover member (1100) may include an opening exposing the lens module by being formed at the upper plate (1101). The opening may be formed in a shape corresponding to the shape of the lens module. The opening may be sized larger than a diameter of the lens module to allow the lens module to be assembled through the opening. In addition, light introduced through the opening may pass through the lens module. Meanwhile, light having passed through the lens module may be irradiated to the image sensor.

The coil former (1200) may be movably supported relative to the housing (1400). The bobbin (1200) can perform an auto-focus function by moving in the optical axis direction with respect to the housing (1400). The bobbin (1200) may be in a state of being accommodated in the base (1600) in an initial state in which the coil of the first driving part (1300) is not supplied with power. That is, the bobbin (1200) may be driven in a single direction. More specifically, the bobbin (1200) may perform an auto-focus function by moving to an upper side in response to power supply in an initial state. At this time, the upper support member (1700) and/or the bottom support member (1800) may be designed to apply pressure to the bobbin (1200) to the base (1600) side in the initial state. This may be illustrated by offsetting the gap between the outer portions (1710, 1810) and the inner portions (1720, 1820) of the upper support member (1700) and/or the bottom support member (1800).

The coil bobbin (1200) may include a lens coupling portion (1210), a first drive portion coupling portion (1220), an upper side coupling portion (1230), a bottom side coupling portion (1240), a stepped portion (1250), and an inner plate receiving groove (1260). However, any one or more of the lens coupling portion 1210, the first driving portion coupling portion (1220), the upper side coupling portion (1230), the bottom side coupling portion (1240), the stepped portion (1250), and the inner plate receiving groove (1260) may be omitted or changed from the coil bobbin (1200).

The bobbin (1200) may include a lens coupling part (1210) coupled by a lens module. The lens coupling part (1210) may be coupled by a lens module. An inner circumferential surface of the lens coupling part (1210) may be formed with a screw thread of a shape corresponding to a shape of a screw thread formed at an outer circumferential surface of the lens module. That is, the outer circumferential surface of the lens module may be screwed to the inner circumferential surface of the lens coupling part (1210). Meanwhile, an adhesive may be injected between the lens module and the bobbin (1200). At this time, the adhesive may be an epoxy resin hardened by UV or heat.

The bobbin (1200) may include a first drive part coupling part (1220) coupled by a first drive part (1300). The first drive section coupling portion (1220) may be received by the first drive section (1300). The first driving part coupling part (1220) may be integrally formed with an outer circumferential surface of the bobbin (1200). Further, the first driving part coupling part (1220) may be continuously formed along the outer circumferential surface of the bobbin (1200) or spaced apart from the outer circumferential surface of the bobbin (1200) by a predetermined distance. The first driving part coupling part (1220) may be formed by recessing a portion of an outer circumferential surface of the bobbin (1200).

The bobbin (1200) may include an upper side coupling portion (1230) coupled with the upper support member (1700). The upper coupling portion (1230) may be coupled to the inner portion (1720) of the upper support member (1700). For example, the lugs (not shown) of the upper coupling portion (1230) may be coupled by insertion into slots or holes (not shown) of the inner portion (1720). When the lugs of the upper side coupling portion (1230) are inserted into the slots or holes of the inner portion (1720), the lugs may be fused or bonded by the adhesive member to couple the upper support member (1700) to the coil bobbin (1200).

The bobbin (1200) may include a bottom side coupling portion (1240) coupled with the bottom support member (1800). The bottom side coupling portion (1240) may be coupled to an inner portion (1820) of the bottom support member (1800). For example, lugs (not shown) of the bottom side coupling portion (1240) may be coupled by insertion into slots or holes (not shown) of the inner portion (1820). When the lugs of the bottom side coupling portion (1240) are inserted into the slots or holes of the inner portion (1820), the lugs may be fused or bonded by the bonding member to couple the bottom support member (1800) to the coil form (1200).

The upper surface of the bobbin (1200) may be formed with a stepped portion (1250) formed downward in a concave manner. The stepped portion (1250) may be arranged by surrounding a circumference of the upper surface of the bobbin (1200). The stepped portion (1250) may be formed not to interfere with the upper side portion (1410) of the housing (1400) when the bobbin (1200) is moved in the optical axis direction (vertical direction). That is, the stepped portion (1250) may fix the moving space to the upper side of the bobbin (1200). The stepped portion (1250) may be formed at an upper surface of the bobbin (1200) and may be disposed at a region where the bobbin (1200) overlaps with an upper side portion (1410) of the case (1400) in the optical axis direction. However, the present invention is not limited thereto, and the stepped portion (1250) may be disposed at a region where the bobbin (1200) and the upper side portion (1410) of the case (1400) do not overlap in the optical axis direction.

In the second exemplary embodiment of the present invention, the bobbin (1200) and the upper side portion (1410) of the case (1400) may be formed as a region allowing the maximum overlap in the optical axis direction. In this case, foreign substances may be introduced into a space between the case (1400) and the bobbin to minimize the introduction into the image sensor. For example, as shown in fig. 20, the bobbin (1200) and the upper side portion (1410) of the case (1400) may overlap so as to prevent a space between the case (1400) and the upper side portion (1410) from being seen when viewed from the upper side.

In the second exemplary embodiment of the present invention, the stepped portion (1250) may be provided with an upper support member (1700). Therefore, the upper support member (1700) in the second exemplary embodiment may be provided to span a wider area than that of other exemplary embodiments in which the stepped portion (1250) is not formed. This means that the connection portion (1730) of the upper support member (1700) can be formed longer to have a wider width.

Typically, the resilient member may be manufactured by an etching process, wherein, for example, the etching tolerance may be about ± 0.007 mm. Further, in the case of a glass photomask, the etching tolerance may be about ± 0.003 mm. Meanwhile, when the width of the elastic member becomes wider, the rigidity of the elastic member can be favorably affected by a smaller tolerance. To help understand this theory, for example, when the width of the elastic member is manufactured to be 1mm, the width of the elastic member may be 1 ± 0.007mm in consideration of the tolerance, but when the width of the elastic member is manufactured to be 0.1mm, the width of the elastic member may be 0.1 ± 0.007mm in consideration of the tolerance. That is, when the width of the elastic member is made wider, the deviation of the rigidity becomes smaller, and in this case, it is advantageous that the deviation of the starting current and the sensitivity of the one-way driving lens driving device (1000) is easily controlled.

However, when the width of the elastic member is wide, it is necessary to extend the length of the elastic member to obtain the same rigidity as the case where the width of the portion wider than the width is narrow. In view of the fact that the receivable area of the upper support member (1700) can be enlarged by allowing the step portion (1250) to surround the circumferential arrangement of the upper surface at the bobbin (1200) in the second exemplary embodiment, it is possible to lengthen the upper support member (1700) having a wider width. That is, in the second exemplary embodiment of the present invention, the rigidity of the upper support member (1700) may be affected by a small tolerance. This means that the deviation in rigidity at the upper support member (1700) is reduced, so that it is advantageous in the second exemplary embodiment of the present invention to easily control the deviation in starting current and sensitivity, as described above.

The bobbin (1200) may include an inner board receiving groove (1260) in which at least a portion of the inner board (1103) of the cover member (1100) may be received. An inner panel receiving groove (1260) may be formed at an upper surface of the bobbin (1200). The inner panel receiving groove (1260) may be formed by recessing a portion of the upper surface at the bobbin (1200) downward. The recessed depth of the inner panel receiving groove (1260) may be deeper than the recessed depth of the stepped portion (1250). At this time, the depth may be defined by a length toward the bottom side at the upper end of the bobbin (1200). Further, when the bobbin (1200) is coupled to the case (1400), an upper surface of the bobbin (1200) forming the inner panel receiving groove (1260) may be disposed at a lower side than an upper surface of the bobbin (1200) forming the stepped portion (1250). That is, the inner panel receiving groove (1260) may assume a shape that is more downwardly concave than the stepped portion (1250). The inner panel receiving groove (1260) may be received by the inner panel (1103) of the cover member (1100), and the received inner panel (1103) may be prevented from rotating since the received inner panel (1103) is locked at the bobbin (1200) forming the inner panel receiving groove (1260). For example, an inner panel receiving groove (1260) may be provided at each of the four (4) corner sides. However, the present invention is not limited thereto.

The first driving part (1300) may be provided to the bobbin (1200). The first driving part (1300) may be fixed by inserting a first driving part coupling part (1220) of the bobbin (1200). For example, the first driving part coupling part (1220) may be formed by allowing the protruding part to be disposed at the upper/bottom side of the recessed area. At this time, the coil of the first driving part (1300) may be directly wound on the first driving part coupling part (1220). Alternatively, as another example, the first driving part coupling part (1220) may have an upper side or a bottom side of the recessed area opened, and may be formed by allowing a hooking part to be formed at the other side, and the coil of the first driving part (1300) may be coupled by being inserted through the opened area while in a pre-wound state.

The first drive portion (1300) may include a coil. The coil of the first driving part (1300) may be guided to the first driving part coupling part (1220) to be wound on the outer circumferential surface of the bobbin (1200). Further, as another exemplary embodiment, the coil may be further formed with four independent coils disposed at an outer circumferential surface of the bobbin (1200), whereby adjacent coils may form an angle of 90 ° with each other. The first driving portion (1300) may be disposed to face the second driving portion (1500). The first drive part (1300) can move the bobbin (1200) relative to the housing (1400) in the optical axis direction by electromagnetic interaction with the second drive part (1500). The coil of the first drive portion (1300) may include a pair of lead cables (1301, 1302). A pair of lead cables (1301, 1302) may receive electrical current by being electrically connected to a pair of bottom support members (1801, 1802). When current is supplied to the coils of the first drive part (1300), the first drive part (1300) may be moved by electromagnetic interaction with the magnets (1501, 1502) of the second drive part (1500), and the coil former (1200) coupled by the first drive part (1300) may also be moved.

The case (1400) may be disposed outside the bobbin (1200). The case (1400) may be opened at upper and bottom sides to movably accommodate the bobbin (1200). An inner circumferential surface of the case (1400) may be spaced apart from an outer circumferential surface of the bobbin (1200). For example, the housing (1400) may be secured to the base (1600). However, in a modification, the housing (1400) may be movably coupled to the base (1600) by a lateral elastic member so as to move to perform a hand trembling correction function. The housing (1400) may be formed of an insulating material, and may be manufactured of an injection molding material in consideration of productivity.

The housing (1400) may include an upper portion (1410), a lateral support portion (1420), and side plates (1430). However, at least any one or more of the upper portion (1410), the lateral support portion (1420), and the side plate (1430) may be omitted or modified from the housing (1400).

The housing (1400) may include an upper portion (1410) supporting an upper surface of the second driving portion (1500). The upper portion (1410) may form an upper surface of the housing (1400) to support an upper surface of the second driving portion (1500). The upper portion (1410) may include a through-hole (1411) therein. Light incident through the through hole (1411) may be incident on the lens module. The upper portion (1410) may overlap the bobbin (1200) at least partially in the optical axis direction. The upper portion (1410) may be formed in the following manner: discrete spaces formed between the inner circumferential surface of the case (1400) and the outer circumferential surface of the bobbin (1200) are not seen when viewed from the upper side of the case (1400). In this case, a phenomenon that foreign materials are introduced through a discrete space between the case (1400) and the bobbin (1200) may be minimized.

The upper portion (1410) may act as a mechanical stop with respect to the coil form (1200). That is, the upper portion (1410) may not contact the bobbin (1200) when the bobbin is moved by the auto-focus function of the bobbin (1200), and may restrict movement in an upper direction of the bobbin (1200) when the bobbin (1200) is moved by an external impact. Alternatively, the upper portion (1410) may act as a stop contacting the bobbin (1200) when the bobbin is moved by the autofocus function of the bobbin (1200). However, during the reliability test, when the upper portion (1410) performs a stopper function with respect to the bobbin (1200), the possibility of generating foreign matter by grinding is high, and therefore, a stopper portion may also be formed between the inner plate (1103) of the cover member (1100) and the bobbin (1200), if necessary. That is, a portion of the inner panel receiving groove (1260) of the bobbin (1200) may contact an end of the inner panel (1103) of the cover member (1100) to allow a stopper function to be achieved.

For example, the upper portion (1410) may include four (4) corner portions. That is, the upper portion (1410) may be rectangular in shape. Each of the four corner portions at the upper portion (1410) may be provided with a lateral support member (1420) extending to the bottom side.

The housing (1400) may include a lateral support portion (1420), the lateral support portion (1420) extending downward from the upper portion (1410) to support a lateral surface of the second drive portion (1500). The lateral support portion (1420) may include first to fourth support portions (1421, 1422, 1423, 1424) extending downward from each of four corner portions of the upper portion (1410). At this time, the first support portion (1421) may be adjacent to the fourth support portion (1424) and the second support portion (1422), and the third support portion (1423) may be adjacent to the second support portion (1422) and the fourth support portion (1424). That is, the first to fourth supporting portions (1421, 1422, 1423, 1424) may be continuously arranged in a clockwise direction or a counterclockwise direction.

The second driving portion (1500) may be interposed between the first supporting portion (1421) and the second supporting portion (1422) and between the third supporting portion (1423) and the fourth supporting portion (1424). Meanwhile, the side plates (1430) may be interposed between the second and third supporting portions (1422, 1423) and between the fourth and first supporting portions (1424, 1421). That is, the two second driving portions (1500) and the two side plates (1430) may be coupled to the lateral support portion (1420). At this time, the two driving portions (1500) may face each other. Further, the two side plates (1430) may also face each other.

The lateral support portion (1420) may include a concave portion (1426), and the concave portion (1426) is concave from a bottom end of the lateral support portion (1420) to an upper side. The recessed portion (1426) may be provided with the extension portion (1620) of the base (1600). The concave portion 1426 may be formed in a shape corresponding to the shape of the extension portion 1620. That is, the lateral support portion (1420) may be formed with a shape corresponding to the shape of the extension portion (1620) of the base (1600) on at least a portion thereof. The lateral support portion (1420) may be further securely coupled by the coupling between the recessed portion (1426) and the extension portion (1620). In particular, when the recess part 1426 is provided at the outer side of the lateral support part (1420), and when the extension part (1620) is received in the recess part (1426), it may be caused that the extension part (1620) supports the outer portion of the lateral support part (1420), thereby minimizing a phenomenon that the housing (1400) is disassembled in the outer direction even if there is an external shock.

The lateral support portion (1420) may include a coupling lug (1427), and the coupling lug (1427) is protrudingly formed from a bottom end of the lateral support portion (1420) to a bottom side. The coupling lug 1427 may be protrudingly formed from a bottom end of the lateral support portion 1420 toward a bottom side. The coupling lug (1427) may be received in the coupling slot (1630) of the base (1600). The attachment lug (1630) may be secured to a slot formed at an outer portion (1810) of the bottom support portion (1800).

The lateral support portion (1420) may include a support end (1425) that supports a portion of an inner surface of the second drive portion (1500). The support end 1425 may support a portion of an inner surface of the second driving portion 1500 to prevent the second driving portion 1500 from being biased inward. Furthermore, at least a portion of the inner surface at the support end (1425) may be supported to allow opening to the interior, thereby minimizing the effect on the electromagnetic interaction between the second drive portion (1500) and the first drive portion (1300).

The side panel (1430) may include a first panel (1431) and a second panel (1432), wherein the first panel (1431) is integrally formed with the second support portion (1422) and the third support portion (1423), and the second panel (1432) is integrally formed with the fourth support portion (1424) and the first support portion (1421). The side plate (1430) may be integrally formed with the lateral support portion (1420), thereby minimizing a phenomenon in which foreign substances are introduced from the side of the case (1400). Meanwhile, as a modification, when the second driving part (1500) is formed with four pieces, the side plate (1430) may be omitted.

The second driving portion (1500) may be disposed to face the first driving portion (1300). The second drive portion (1500) may move the first drive portion (1300) by electromagnetic interaction with the first drive portion (1300). The second drive portion (1500) may comprise a magnet. For example, the second drive portion (1500) may comprise two magnets. For example, the second driving part (1500) may include a first magnet (1501) and a second magnet (1502), as shown in fig. 16. At this time, the first magnet (1501) and the second magnet (1502) may be disposed to face each other. As indicated herein, when two magnets are arranged, two surfaces of four lateral surfaces of the case (1400) may be provided with side plates (1430) to minimize a phenomenon in which foreign substances are introduced from the side surfaces (1400) of the case.

As shown in fig. 22, in a modification, the second driving portion (1500) may include four magnets. At this time, four magnets may be provided on the housing (1400) by being independently arranged to form 90 ° between adjacent two magnets. That is, each of the four magnets is disposed on each lateral surface of the four lateral corners of the housing (1400) to facilitate efficient utilization of the interior volume.

The second driving part (1500) may be provided to the housing (1400). The second driving part (1500) may be fixed by being inserted into the housing (1400). More specifically, the upper surface of the second driving part (1500) may be supported to the upper part (1410) of the housing (1400), and the lateral surface may be supported by the lateral support part (1420) of the housing (1400). Further, a bottom surface of the second driving portion (1500) may be supported by the base (1600). The upper support member (1700) may be interposed between the second drive portion (1500) and the upper portion (1410). An adhesive may be interposed between the second drive portion (1500) and the housing (1400) and/or the base (1600).

Meanwhile, as a modification, the first driving part (1300) may include a magnet, and the second driving part (1500) may include a coil.

The base (1600) may support the bottom side of the housing (1400). The base (1600) may be coupled with the housing (1400). The base (1600) may be coupled with the cover member (1100). The base (1600) may be coupled with an outer plate (1102) of the cover member (1100). At least a portion of the outer surface at the base (1600) may contact an inner surface of the outer plate (1102) of the cover member (1100). The bottom end of the base (1600) may be formed with a lug protruding to the outside to support the bottom end of the outer plate (1102) of the cover member (1100).

The base (1600) may include a bottom portion (1610), an extension portion (1620), and a coupling slot (1630). However, any one or more of the bottom portion (1610), the extension portion (1620), and the coupling slot (1630) may be omitted or changed from the base (1600).

The base (1600) may include a bottom portion (1610) that supports the housing (1400). The bottom portion (1610) may support a bottom end of the lateral support portion (1420) of the housing (1400). The bottom portion (1610) may include a through hole (1611) therein.

The bottom portion (1610) may include a coupling slot (1630) at a portion of the lateral support portion (1420) of the support housing (1400). Meanwhile, the bottom end of the lateral support portion (1420) may be formed with a coupling lug (1427) inserted into the coupling groove (1630). The coupling lug (1427) may couple with a hole formed at an outer portion (1810) of the base support member (1800). That is, the bottom support member (1800) may be interposed between the bottom portion (1610) of the base (1600) and the lateral support portions (1420) of the housing (1400). Meanwhile, the bottom support member (1800) may be fixed by coupling lugs (1427) coupled to the lateral support portions (1420), the coupling lugs (1427) of the lateral support portions (1420) being inserted into the coupling grooves (1630) of the bottom portion (1610). The bottom portion (1610) may include a terminal receiver (1612) formed on a side surface by being inwardly recessed.

Further, a portion of the upper support member (1700) may be fixed to the housing (1400) and/or the second driving portion (1500) by adhesive bonding.

The upper support member (1700) may include a resilient member. That is, at least a portion of the upper support member (1700) may have elasticity. In this case, the upper support member (1700) may be referred to as an upper elastic member. For example, the upper support member (1700) may be a leaf spring. However, the present invention is not limited thereto. At least a portion of the upper support member (1700) may have a shape corresponding to the shape of the lateral support portion (1420), by means of which upper support member (1700) at least a portion of the lateral support portion (1420) may be received. Meanwhile, in this case, when an external force is applied to the upper bearing portion (1700), the upper bearing portion (1700) can be prevented from rotating by being locked at the lateral bearing portion (1420).

The upper support member (1700) may include an outer portion (1710), an inner portion (1720), and a connecting portion (1730). The upper support member (1700) may include: an outer portion (1710) supported by the housing (1400), an inner portion (1720) coupled with the coil former (1200), and a connecting portion (1730) connecting the outer portion (1710) and the inner portion (1720). At this time, the connection portion (1730) of the upper support member (1700) may have elasticity. It is apparent that the entire upper support member (1700) may also be resilient.

At least a portion of the upper support member (1700) may include an outer portion (1710) interposed between the upper portion (1410) and the second drive portion (1500). At least a portion of the outer portion (1710) may be interposed between the upper portion (1410) and the second drive portion (1500). The outer portion (1710) may be in surface contact with the housing (1400) at one surface thereof and may be in surface contact with the second driving portion (1500) at the other surface. The outer portion (1710) may be secured between the second drive portion (1500) and the upper portion (1410) by a force coupled to the housing (1400) by the second drive portion (1500).

The outer portion (1710) may include a first outer terminal (1711) interposed between the first and second support portions (1421, 1422), a second outer terminal (1712) interposed between the second and third support portions (1422, 1423), a third outer terminal (1713) interposed between the third and fourth support portions (1423, 1424), and a fourth outer terminal (1714) interposed between the fourth support portion (1424) and the first support portion (1421).

The upper support member (1700) may include an inner portion (1720) coupled to an upper surface of the bobbin (1200). The inner portion (1720) may be coupled to an upper surface of the bobbin (1200). The inner portion (1720) may be formed with a hole, and the bobbin (1200) may be formed with a lug corresponding to the hole. When the lugs of the bobbin (1200) are inserted into the holes of the inner portion (1720), the inner portion (1720) may be coupled to the bobbin (1200) by heat melting. Inner portion (1720) may be connected to outer portion (1710) by a connecting portion (1730).

For example, the connection portion (1730) may include a first connection body (1731a) connected between the second internal terminal 1722, the third internal terminal (1723), and the first external terminal (1711), as shown in fig. 20. In addition, the connection part (1730) may further include a second connection body (1732a) connected between the third internal terminal (1723), the fourth internal terminal (1724), and the second external terminal (1712). In this case, the second external terminal (1712) may be fixed to the housing (1400) by an adhesive. Meanwhile, the first connection body (1731a) and the second connection body (1732a) shown in fig. 20 may be determined to be longer in length than the first connection body (1731b) and the second connection body (1732b) of fig. 21 as a modification. That is, the first connection body (1731a) and the second connection body (1732a) shown in fig. 20 are used to have a width wider than that of the first connection body (1731b) and the second connection body (1732b) as a modification of fig. 21 to show the same rigidity as that of the first connection body (1731b) and the second connection body (1732b) of fig. 21. That is, there is an advantage in that less manufacturing errors are received in the exemplary embodiment of fig. 20.

As shown in fig. 21, as a modification, the connection portion (1730) may include a first connection body (1731b) connected between the first external terminal (1711) and the second internal terminal (1722), and a second connection body (1732b) connecting the first external terminal (1711) and the fourth internal terminal (1724). In this case, the connection portion (1730) may not be directly connected to the second external terminal (1722). Meanwhile, this modification has an advantage of eliminating the use of an adhesive to fix the second external terminal (1712) and the fourth external terminal (1714) to the housing (1400) as compared with the exemplary embodiment of fig. 20.

An adhesive (not shown) may be interposed between the outer portion (1710) and the upper portion (1410). Alternatively, adhesive may be interposed between the outer portion (1710) and the second drive portion (1500). That is, adhesive may be interposed between the outer portion (1710) and the upper portion (1410) or between the outer portion (1710) and the second drive portion (1500).

A portion of the bottom support member (1800) may be coupled to the case (1400) or the base (1500), and another portion may be coupled to the bottom surface of the bobbin (1200). A portion of the bottom support member (1800) may be fixed by a coupling lug (1427) provided at a bottom end of the lateral support portion (1420) at the housing (1400). A portion of the bottom support member (1800) may be interposed between the lateral support portions (1420) of the housing 1400 and the base (1600). The bottom support member (1800) may movably support the coil former (1200) with respect to the housing (1400) and/or the base (1500). The bottom support member (1800) may be formed to apply a pressure to the bottom side on the bobbin (1200) during an initial state in which no current is applied to the first driving part (1300). Further, the upper support member (1700) may be formed to apply a pressure to the bottom side on the bobbin (1200) during an initial state in which no current is applied to the first driving part (1300), whereby the bobbin 1200) may be maintained in a state of being in contact with the base (1600) in the initial state. That is, according to the second exemplary embodiment of the present invention, the auto-focus function may be performed by unidirectional driving. The base support member (1800) may be formed in a pair of base support members (1801, 802). The bottom support members (1800) may be formed in a pair, wherein each bottom support member may be connected to a coil of the first driving part (1300).

For example, the base support member (1800) may comprise a resilient member. That is, at least a portion of the base support member (1800) may be resilient. In this case, the bottom support member (1800) may be referred to as a bottom elastic member. For example, the bottom support member (1800) may be a leaf spring. However, the present invention is not limited thereto.

The bottom support member (1800) may include an outer portion (1810), an inner portion (1820), and a connecting portion (1830).

The bottom support member (1800) may include an outer portion (1810) connected to any one or more of the housing (1400) and the base (1600). The outer portion (1810) may be coupled to any one or more of the housing (1400) and the base (1600). The outer portion (1810) may be secured by a coupling lug (1427) at the lateral support portion (1420). The outer portion (1810) may comprise a hole into which the coupling lug (1427) of the lateral support portion (1420) is inserted.

Each of the pair of bottom support members (1801, 802) may include a terminal portion (1811) bent downward to be received into a terminal receiver (1612) of the base (1600). The terminal portion (1811) may extend by bending from the outer portion (1810). At least a portion of the terminal portion (1811) may be received into a terminal receiver (1612) of the base (1600). The terminal portion (1811) may be applied with a band spring terminal manufactured by a banding method.

The bottom support member (1800) may include an inner portion (1820) coupled to the coil form (1200). The inner portion (1820) may be coupled to the bobbin (1200). The inner portion (1820) may include an aperture, and the coil former (1200) may include a lug. In this case, the hole of the inner portion (1820) may be connected by being inserted by a lug of the bobbin (1200). When the hole of the inner portion (1820) is inserted into the lug of the bobbin (1200), the inner portion (1820) may be coupled and bonded to the bobbin (1200) by heating.

The bottom support member (1800) may include a connecting portion (1830) connecting the outer portion (1810) and the inner portion (1820). The connection portion (1830) may include an outer portion (1810) and an inner portion (1820). The connection portion (1830) may have elasticity. It should be apparent that the outer portion (1810), the inner portion (1820) and the connecting portion (1830) are all resilient.

The second exemplary embodiment and modification may be such that the assembly of the housing assembly may be performed by the following process: as shown in fig. 23(a), the cover member 1100 is housed, and the housing (1400) is disposed inside the cover member 1100; as shown in fig. 23(b), the upper support member (1700) is accommodated on the housing (1400); and as shown in fig. 23(c), the magnet of the second driving portion (1500) is fastened.

The second exemplary embodiment of the present invention has an advantage over the prior art in that a fixing process such as an adhesive process or a fusing process for fixing the upper support member (1700) to the housing (1400) is eliminated. Further, another advantage of the second exemplary embodiment of the present invention is that since the magnet may be assembled in the vertical direction of the case (1400), the assembly is easy compared to the case where the case (1400) is assembled at the side.

In the second exemplary embodiment of the present invention, the magnets are positioned at only two lateral surfaces among the four lateral surfaces of the housing (1400), and the other remaining two lateral surfaces are positioned with, for example, side plates, to thereby reduce the risk of foreign substances being introduced from the lateral surfaces of the housing (1400).

Meanwhile, as an example, when the upper support member (1700) is used as shown in fig. 20, the length of the upper support member (1700) may be lengthened and the width may be widely utilized, thereby minimizing the influence of rigidity caused by manufacturing tolerance. Further, as a modification, when the upper support member (1700) is used as shown in fig. 21, the outer portion (1810) which is not directly connected by the connection portion (1830) may advantageously dispense with a bonding process in which the outer portion (1810) is separately bonded to the housing (1400).

According to the second exemplary embodiment of the present invention, the inner diameter of the case (1400) may be made smaller than the outer diameter of the bobbin (1200) to minimize the intrusion of foreign substances to the upper side.

Further, according to the second exemplary embodiment of the present invention, the number of manufacturing personnel for assembling the housing can be reduced to a total of six. That is, the case assembly can be accomplished by employing one person for housing the cover member (1100), one person for housing the case (1400), one person for housing the upper support member (1700), one person for coating the bonding, one person for assembling the magnet, and one person for performing additional adhesive coating. Furthermore, the second exemplary embodiment of the present invention may expect the advantageous effect of reducing the cost of the jig relative to the prior art, thereby reducing the manufacturing cost of the housing (1400) and the magnet as compared to the prior art, and reducing the loss of sub-assembly defects as compared to the prior art.
