The movable portion is driven in a direction perpendicular to the optical axis of the lens assembly within the fixed portion or around the optical axis.

[0003] Figure 9 This diagram shows an example of the configuration of a conventional camera device of this type. This camera device includes an AF motor 810 (serving as a lens assembly), a housing 820, a support leaf spring 830, a bracket 840, a plate 850, a magnet 860, a suspension wire 870, a coil substrate 880, an FPC 890, an image sensor 900, a sensor substrate 910, a frame 920, and a base plate 930. The AF motor 810, housing 820, bracket 840, plate 850, magnet 860, frame 920, and base plate 930 constitute the fixed portion, while the coil substrate 880, FPC 890, image sensor 900, and sensor substrate 910 constitute the movable portion.

[0004] In this camera apparatus, the bracket 840 has protrusions on the front surfaces of the four walls surrounding the through-hole supporting the AF motor 810 , and the protrusions are bonded to the rear surface of the front plate of the housing 820 . Summary of the Invention

[0005] [Problems to be solved by the invention]

[0006] However, a problem with conventional camera devices of this type is that the bonding strength between the bracket and the housing is sometimes insufficient.

[0007] The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide an optical component driving device, a camera device, and an electronic device in which the bonding strength between a holder and a housing is high.

[0008]

Methods for solving the problem

[0009] In order to solve the above-mentioned problems, as a preferred embodiment of the present invention, an optical component driving device is characterized in that it comprises: a frame-shaped bracket which accommodates the lens device; a box-shaped shell which accommodates the bracket; and a movable part which has a holding part for holding an image sensor and is supported to be freely swingable at a rear position of the lens device, the shell having a front plate having a through hole, the bracket having a protrusion on its front surface which is inserted into the through hole, and the width of the protrusion being greater than the width of the through hole on the front side of the through hole.

[0010] In this aspect, a recessed portion in which the through-hole is provided may be formed in the front plate, and a front end of the protrusion may be located further rearward than a portion of the front plate adjacent to the recessed portion.

[0011] Alternatively, an adhesive may be interposed between the front plate and the front surface.

[0012] Alternatively, the front plate may be further provided with a positioning hole, and the front surface may be further provided with a positioning protrusion inserted into the positioning hole, wherein the positioning protrusion directly rises from a groove annularly formed around the front plate.

[0013] Furthermore, the protrusion may be formed on a platform portion higher than a position where a front end portion of a support leaf spring is fixed, and a suspension wire connected to the movable portion may be attached to a base end portion of the support leaf spring.

[0014] A camera device according to another preferred embodiment of the present invention is characterized by including the above-mentioned optical component driving device.

[0015] Another preferred embodiment of the present invention is an electronic device including the camera device described above.

[0016] Effects of the invention

[0017] The optical component driving device of the present invention comprises: a frame-shaped holder that houses a lens assembly; a box-shaped housing that houses the holder; and a movable portion that secures an image sensor and is swingably supported at a position behind the lens assembly. The housing includes a front plate having a through-hole, and the holder includes a protrusion on its front surface that is inserted into the through-hole. The width of the protrusion is greater than the width of the through-hole on the front side of the through-hole. Therefore, the width of the protrusion is greater than the width of the through-hole on the front side of the through-hole, thereby providing an optical component driving device that is less likely to fall off the holder from the housing and has a high bonding strength between the holder and the housing.

[0027] like Figure 1 As shown, a camera device 101 including an optical component driving device 100 as one embodiment of the present invention is housed in a housing of a smartphone 109. The camera device 101 includes an AF (Auto Focus) motor 102 as a lens device, an image sensor 107 as an optical component, and the optical component driving device 100. The AF motor 102 includes a lens body 110 and an actuator that drives the lens body 110 in a direction parallel to the optical axis of the lens body 110. The image sensor 107 converts light transmitted through the lens body 110 into an image signal and outputs the image signal. The optical component driving device 100 fixes the AF motor 102 and the image sensor 107 and drives the image sensor 107 in a direction perpendicular to the optical axis of the lens body 110 of the AF motor 102 and in a direction rotating about the optical axis. The lens device does not necessarily have an actuator that drives in a direction parallel to the optical axis of the lens body 110.

[0028] Hereinafter, the optical axis direction of the lens body 110 is referred to as the Z direction, a direction perpendicular to the Z direction is referred to as the X direction, and a direction perpendicular to both the Z direction and the X direction is referred to as the Y direction. When viewed from the lens body 110, the +Z side, which is the subject side, is sometimes referred to as the front side, and the -Z side, which is the opposite side (the image sensor 107 side), is sometimes referred to as the rear side.

[0029] like Figure 3 As shown, the optical component driving device 100 includes a housing 1, four suspension wires 2, four support leaf springs 3, a bracket 4, four magnets 5, a coil substrate 6, an FPC (Flexible Printed Circuit) 7, four driver ICs 8, and a base plate 9. Among the various components, the housing 1 and base plate 9 form a frame that houses the suspension wires 2, support leaf springs 3, the bracket 4, the magnets 5, the coil substrate 6, the FPC 7, and the driver IC 8.

[0030] The housing 1, base plate 9, bracket 4, and magnet 5 constitute the fixed portion, while the coil substrate 6, FPC 7, and driver IC 8 constitute the movable portion. The support leaf spring 3 and suspension wire 2 connect the fixed and movable portions and support the movable portion. The AF motor 102 is housed and fixed within the storage space formed by the bracket 4, which forms the frame of the fixed portion. The image sensor 107 is mounted on a sensor substrate (not shown), which is fixed to the rear surface of the FPC 7, which forms the movable portion. The rear surface of the FPC 7 serves as the retaining portion for the image sensor 107.

[0031] like Figure 6 As shown, the coil substrate 6 comprises a main body 600 and a first stopper 610 and a second stopper 620 protruding outward from the periphery of the main body 600. A rectangular through-hole 69 is provided in the center of the main body 600 of the coil substrate 6, with both the outer and inner shapes forming a quadrilateral ring. Two coils 65 are provided on each side of the quadrilateral of the main body 600.

[0032] FPC 7 is a three-dimensional component formed by folding a thin, point-symmetrical plate. It consists of a main body 70 and two point-symmetrically arranged connecting portions 71. A rectangular through-hole 79 is provided in the center of main body 70, creating a four-cornered ring with both a quadrilateral outer and inner shape. The coil substrate 6 is secured to the front surface of main body 70.

[0033] like Figure 7As shown, for the two connecting parts 71 of the FPC 7, the base end portion 73 rises forward from the specified position on the +X side and -X side of the main body 70. The base end portion 73 of the connecting part 71 of the FPC 7 is opposite to the side of the main body 600 of the coil substrate 6 and is sandwiched with adhesive. In other words, the base end portion 73 is bonded and fixed to the coil substrate 6 by the adhesive. The adhesive can also be squeezed out to the front side from the gap between the base end portion 73 of the FPC 7 and the peripheral edge of the coil substrate 6. The specified position is a position near a corner of a specified diagonal corner, and the specified diagonal corner is the corner of the +X+Y side and the corner of the -XY side. The connecting part 71 extends along each side toward the side opposite to the specified diagonal corner. When it reaches the corner of the adjacent side, it extends along the adjacent side and falls back to the rear at the specified position. The specified position is a position near the other corner of the specified diagonal corner. The connecting portion 71 that falls to the rear side is bent outward in the Y direction at the same height as the bottom plate 9, and protrudes outward from the housing 1 through the gap between the rear edge of the housing 1 and the bottom plate 9. In this way, the FPC 7 covers the outside of the bracket 4 except for the specified diagonal portion. Figure 4 As shown, the rear edge of the portion extending along both sides of the connecting portion 71 is positioned on the front side relative to the coil substrate 6 as a whole.

[0034] The front end of the portion of the connecting portion 71 that protrudes toward the outside of the housing 1 is T-shaped, and a plurality of connection terminals are provided on the rear surface of the T-shaped portion. A driver IC 8 is provided on each side of the quadrilateral of the main body 70, and the driver IC 8 is fixed to the rear surface of the FPC 7 directly behind the coil 65 on each side near the specified diagonal corners of the quadrilateral. In addition, a sensor substrate on which the image sensor 107 is mounted is mounted on the rear surface of the main body 70, and the light-receiving surface of the image sensor 107 is exposed toward the front side from the through hole 79. The coil 65 and the image sensor 107 are electrically connected to the main body of the smartphone 109 via the FPC 7.

[0035] As described above, the first stopper 610 and the second stopper 620 protrude outward from the periphery of each side of the main body 600 of the coil substrate 6. Each of the first stopper 610 and the second stopper 620 directly faces the inner surface of the housing 1. Conversely, between the outer periphery of the main body 600 of the coil substrate 6 and the inner surface of the housing 1 lies the base end 73 of the connecting portion 71 of the FPC 7 and the portion where the connecting portion 71 falls. The two stoppers 610 and 620 protrude outward from a portion where the FPC 7 is not present on the outer periphery. The base end 73 faces the side of the main body 600 of the coil substrate 6 and is located inward of the outer ends of the two stoppers 610 and 620. The first stopper 610 is located between the other diagonal corner that is not the specified diagonal corner and the point immediately before the FPC 7 is present on the outer periphery, while the second stopper 620 is located between the specified diagonal corner and the point immediately before the FPC 7 is present on the outer periphery. When the movable part moves in the XY directions or rotates around the Z axis, the first blocking part 610 and the second blocking part 620 come into contact with the inner surface of the housing 1 before any other part of the movable part. Therefore, it is preferred that the first blocking part 610 and the second blocking part 620 are arranged near the corner. The function of the first blocking part 610 and the second blocking part 620 as a blocking member can be exerted by only one of them. However, by adopting a structure in which the base end part 73 of the FPC 7 is clamped between the first blocking part 610 and the second blocking part 620, it is possible to prevent the base end part 73 from coming into contact with the inner surface of the housing 1 before the first blocking part 610 and the second blocking part 620 during movement. In addition, an electrical connection part 621 is provided on the rear surface of the second blocking part 620, which is electrically connected to the main body 70 of the FPC 7.

[0036] The bracket 4 is a quadrilateral frame-shaped structure viewed from the Z direction, with two pairs of walls 41 facing each other in the X and Y directions. At the corners where the walls 41 intersect, there are cutouts 43 with the inner sides cut into four semi-arcs. On the front surface of the wall 41, there are two steps of a platform 480 protruding forward, extending from the corners toward the center of the sides. The platform 480 has a central frontmost surface 481 and two intermediate surfaces 482 on either side.

[0037] A positioning protrusion 413 is provided at the center of the frontmost surface 481 of the platform portion 480 of the wall portion 41 facing in the Y direction. Two protrusions 414 are provided on either side of the positioning protrusion 413 in the X direction. The positioning protrusion 413 rises directly from a groove formed annularly around it. The frontmost surface 481 of the platform portion 480 of the wall portion 41 facing in the X direction is divided into two sides with the central pit 420 sandwiched therebetween. Two protrusions 414 are provided on either side of the pit 420 in the Y direction. Furthermore, small protrusions 46 are provided on each of the eight middle sections 482 of the platform portion 480 of the wall portion 41.

[0038] like Figure 2As shown, the bracket 4 is covered by the shell 1. The shell 1 is box-shaped and has a front plate 10 that is a quadrilateral when viewed from the Z direction and side plates 11 extending from each edge of the front plate 10 to the rear side. A rectangular through-hole 19 is provided in the center of the front plate 10 covering the front side of the bracket 4 in the shell 1. The shape and size of the through-hole 19 are substantially the same as the shape and size of the inner shape of the wall portion 41 of the bracket 4. When the AF motor 102 is accommodated in the bracket 4, the front side of the AF motor 102 is exposed from the through-hole 19. On the front plate 10, a recess 180 that is recessed toward the rear side is provided at the center position of each side of the quadrilateral. On each recess 180, two through-holes 14 are provided along the side. A positioning hole 13 is also provided in the recess 180 on the +X side and the -X side. The positioning hole 13 is located in the middle between the two through-holes 14.

[0039] The positioning protrusion 413 of the bracket 4 is inserted into the positioning hole 13 of the front plate 10 of the housing 1. At this time, the platform 480 and the rear surface of the recess 180 are in contact, and the groove around the positioning protrusion 413 makes it difficult for the rear surface of the recess 180 to float relative to the platform 480. The protrusion 414 of the bracket 4 is inserted into the through hole 14 of the front plate 10 of the housing 1 and fixed by heat riveting. Figure 5 As shown, the width of the protrusion 414 on the front side of the through-hole 14 is wider than the width of the through-hole 14, making it difficult for the bracket 4 to fall off the housing 1. This wider width corresponds to the larger diameter of the circular cross-section after heat caulking. In addition, the front end of the protrusion 414 is located further back than the portion of the front plate 10 adjacent to the recess 180.

[0040] like Figure 4 as well as Figure 8 As shown, a flange portion 45 is provided on the inner side of the wall portion 41 of the bracket 4. The flange portion 45 has a first protrusion that protrudes inward from the rear end of the inner side of the wall portion 41 and then protrudes rearward from the inner end. The AF motor 102 is housed in the space enclosed by the inner side of the wall portion 41 and the front surface of the flange portion 45 in the bracket 4. The outer surface of the AF motor 102 is bonded to the inner side of the wall portion 41.

[0041] The rear surface of the wall portion 41 of the bracket 4 is bonded and fixed to the front surface of the magnet 5. The magnet 5 is in the shape of an elongated rectangular parallelepiped and is arranged along the wall portion 41. There is a coil substrate 6 on the rear side of the magnet 5. The magnet 5 and the coil 65 on the coil substrate 6 are spaced apart and face each other. Preferably, the outer side surface of the wall portion 41, which also exists on the outer side surface of the bracket 4, is parallel to the outer side surface of the magnet 5, thereby forming the same surface. The corners of the outer side surface between the rear surface of the bracket 4, which serves as the bonding surface bonded to the magnet 5, are chamfered, and an inclined surface 453 is provided. In addition, the corners of the front surface and the outer side surface, which serve as the bonding surface of the magnet 5 bonded to the bracket 4, are chamfered, and an inclined surface 52 is provided. The adhesive between the wall portion 41 and the magnet 5 in the contact surface is squeezed into these chamfered portions, forming an adhesive storage portion. That is, a sufficient amount of adhesive is supplied between the rear surface of the bracket 4 and the front surface of the magnet 5, and the excess adhesive can be stored in the space formed by the two inclined surfaces 453 and 52. However, the adhesive is exposed so as not to exceed the outer side surfaces of the bracket 4 and the magnet 5 and reach the outside. In addition, adhesive is sandwiched between the surface facing the outside of the first protrusion 451 and the inner side surface of the magnet 5, and the magnet 5 is also bonded and fixed by the first protrusion 451. In addition, the magnet 5 has two peripheral end surfaces 51 intersecting with the front surface and the outer side surface, and the bracket 4 has two second protrusions 452 protruding backward from the rear surface and sandwiching the magnet 5. Adhesive is sandwiched between each peripheral end surface 51 and the opposite surface of the second protrusion 452 opposite to the peripheral end surface 51, and the magnet 5 is also bonded and fixed by the second protrusion 452. In addition, as Figure 5 As shown, at the position where the magnet 5 is bonded and fixed on the rear surface of the bracket 4, a groove 454 that is an adhesive storage portion recessed toward the front side is provided.

[0042] The portion of the bracket 4 excluding the corners on the +X+Y side and the -XY side is surrounded by the connecting portion 71 of the FPC 7. The corners on the +X+Y side and the -XY side of the bracket 4 are not surrounded by the connecting portion 71 and are exposed to the outside.

[0043] like Figure 3 as well as Figure 4 As shown in FIG. 1 , the support leaf spring 3 is substantially L-shaped. A circular hole is provided at the base end portion of the support leaf spring 3 and at the front end portion thereof extending at a right angle thereto.

[0044] The front end of the support leaf spring 3 is fixed to the middle surface 482 of the platform 480 of the bracket 4. The small protrusion 46 of the middle surface 482 of the platform 480 fits into the circular hole at the front end of the support leaf spring 3. The base end of the support leaf spring 3 floats in front of the notch 43 of the bracket 4. Round holes are located at the four corners of the coil substrate 6 at positions corresponding to the round holes at the front end of the support leaf spring 3.

[0045] The suspension wire 2 passes through the cutout 43 of the bracket 4 and is suspended between the circular hole at the base end of the support leaf spring 3 and the circular hole of the coil substrate 6. That is, the front end of the suspension wire 2 is inserted through and soldered to the circular hole at the base end of the support leaf spring 3, and the rear end is inserted through and soldered to the circular holes at the four corners of the coil substrate 6. In addition, at each corner of the specified diagonal corners exposed from the FPC 7, namely the +X+Y side and the XY side, the end side faces, namely the circumferential end faces 51, which are facing each other at right angles. Each circumferential end face 51 and the front side face, namely the front surface, of the coil substrate 6 facing the movable part are spanned by a viscoelastic resin. The viscoelastic resin is a so-called shock-absorbing glue. The straddling circumferential end faces 51 are the circumferential end face 51 of the +Y side magnet 5 facing the +X direction, the circumferential end face 51 of the -Y side magnet 5 facing the -X direction, the circumferential end face 51 of the +X side magnet 5 facing the +Y direction, and the circumferential end face 51 of the -X side magnet 5 facing the -Y direction. Therefore, a vibration reduction effect can be obtained in both the X and Y directions.

[0046] The above details the structure of this embodiment. The optical component driving device 100 of this embodiment includes: a frame-shaped bracket 4 that houses the AF motor 102, which serves as a lens assembly; a box-shaped housing 1 that houses the bracket 4; and a movable portion having a retaining portion for retaining the image sensor 107 and supported in a swingable manner behind the AF motor 102. The housing 1 includes a front plate 10 having a through-hole 14. The bracket 4 has a protrusion 414 on its front surface that is inserted into the through-hole 14. The width of the protrusion 414 is greater than the width of the through-hole 14 in front of the through-hole 14. Therefore, the width of the protrusion 414 is greater than the width of the through-hole 14 in front of the through-hole 14, thereby providing an optical component driving device 100 that is less likely to fall out of the housing 1 and provides a high bonding strength between the bracket 4 and the housing 1.

[0047] Furthermore, in the above embodiment, the viscoelastic resin may not span the peripheral end surface 51 of the corner facing the +XY side and the -XY side, and the front surface of the coil substrate 6. Furthermore, the spanning portion need not be the peripheral end surface 51; for example, the spanning portion may be the top surface of the corner facing the second protrusion 452 of the bracket 4. In this case, the second protrusion 452 may extend further to the rear than shown. Furthermore, the spanning movable portion need not be the coil substrate 6; for example, the FPC 7 may be positioned in front of the coil substrate 6 and spanned.

[0048] Furthermore, in the above embodiment, the protrusions 414 of the bracket 4 and the through-hole 14 of the housing 1 do not need to be provided with two protrusions 414 on each side of the through-hole 19. They may be provided only on two opposing sides, or one protrusion 414 may be provided on each side, or three or more protrusions may be provided on each side. Furthermore, it is preferred that the number of protrusions 414 on each opposing side is the same, but the number of protrusions 414 may vary between different opposing sides.

[0049] Furthermore, in the above embodiment, the protrusion 414 of the bracket 4 may be fixed to the through hole 14 of the housing 1 by riveting and adhesive, with the housing 1 and the bracket 4 being bonded together by the adhesive. In this case, the adhesive may be sandwiched between the front surface of the bracket 4 and the rear surface of the front plate 10 of the housing 1.
