[0029] As Figure 1As shown, the camera device 101 including the optical component driving device 100 as an embodiment of the present invention is housed in the housing of the 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 has 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 the light conducted through the lens body 110 into an image signal and outputs it. 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 orthogonal to the optical axis of the lens body 110 of the AF motor 102 and in a direction of rotation about the optical axis. As the lens device, an actuator that drives in a direction parallel to the optical axis of the lens body 110 may not be provided.

[0030] Hereinafter, the optical axis direction of the lens body 110 will be appropriately referred to as the Z direction, one direction orthogonal to the Z direction will be appropriately referred to as the X direction, and the direction orthogonal to both the Z direction and the X direction will be appropriately referred to as the Y direction. When viewed from the lens body 110, the +Z side on the subject side may be referred to as the front side, and the -Z side on the opposite side (the image sensor 107 side) may be referred to as the rear side.

[0031] As Figure 3 As shown, the optical component driving device 100 includes a housing 1, four suspension wires 2, four support plate springs 3, a bracket 4, four magnets 5, a coil substrate 6, an FPC (Flexible printed circuits) 7, four driver ICs 8, and a bottom plate 9. Among these components, the housing 1 and the bottom plate 9 are combined as a housing, and in this housing, the suspension wires 2, the support plate springs 3, the bracket 4, the magnets 5, the coil substrate 6, the FPC 7, and the driver ICs 8 are housed.

[0032] The housing 1, the bottom plate 9, the bracket 4, and the magnets 5 constitute a fixed part, and the coil substrate 6, the FPC 7, and the driver ICs 8 constitute a movable part. The support plate springs 3 and the suspension wires 2 fixedly connect the fixed part and the movable part and support the movable part. The AF motor 102 is housed and fixed in the housing space formed by the bracket 4 of the housing body constituting the fixed part. The image sensor 107 is mounted on a sensor substrate (not shown), and the sensor substrate is fixed to the rear surface of the FPC 7 constituting the movable part. The rear surface of the FPC 7 is a holding part for holding the image sensor 107.

[0033] As Figure 6As shown, the coil substrate 6 has a main body portion 600, a first blocking portion 610 and a second blocking portion 620 that protrude outward from the peripheral edge of the main body portion 600. A rectangular through-hole 69 is provided at the center of the main body portion 600 of the coil substrate 6, and both the outer shape and the inner shape form a quadrilateral four-corner ring. Two coils 65 are provided on each side portion of the quadrilateral of the main body portion 600.

[0034] The FPC 7 is a component formed by folding a point-symmetric thin plate into a three-dimensional shape. The FPC 7 has a main body portion 70 and two connecting portions 71 that are point-symmetrically arranged. A rectangular through-hole 79 is provided at the center of the main body portion 70 of the FPC 7, forming a quadrilateral four-corner ring with both the outer shape and the inner shape being quadrilaterals. The coil substrate 6 is fixed to the front surface of the main body portion 70.

[0035] As Figure 7 shown, for the two connecting portions 71 of the FPC 7, the base ends 73 stand up forward from the specified positions on the side portions of the +X side and the -X side of the main body portion 70. The base ends 73 where the connecting portions 71 of the FPC 7 stand up face the side surface of the main body portion 600 of the coil substrate 6 and are clamped by an adhesive. That is, the base ends 73 are adhesively fixed to the coil substrate 6 by the adhesive. The adhesive can also be extruded forward from the gap between the base ends 73 of the FPC 7 and the peripheral edge of the coil substrate 6. The specified position is a position close to one corner portion of the specified diagonal, and the specified diagonal is the corner portion on the +X+Y side and the -X-Y side. The connecting portion 71 extends along each side portion toward the side opposite to the specified diagonal. When it reaches the corner portion of the adjacent side portion, it extends along the adjacent side portion and falls backward at the specified position. The specified position is a position close to the other corner portion of the specified diagonal. The connecting portion 71 that has fallen backward bends 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 trailing 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 portion of the specified diagonal. As Figure 4 shown, the entire trailing edge of the portion extending along the two side portions of the connecting portion 71 is located in front of the coil substrate 6.

[0036] The front end of the portion where the connecting portion 71 protrudes outward from the housing 1 is T-shaped, and a plurality of connection terminals are provided on the rear surface of the T-shaped portion. Driver ICs 8 are respectively provided on each side portion of the quadrilateral of the main body portion 70, and the driver ICs 8 are fixed to the rear surface of the FPC 7 at positions directly behind the coils 65 on each side portion close to the specified diagonal of the quadrilateral. In addition, a sensor substrate on which an image sensor 107 is installed is mounted on the rear surface of the main body portion 70, and the light-receiving surface of the image sensor 107 is exposed forward through the through-hole 79. The coils 65 and the image sensor 107 are electrically connected to the main body of the smartphone 109 via the FPC 7.

[0037] As described above, the first blocking portion 610 and the second blocking portion 620 project outward from the peripheral edges of the respective side portions of the main body portion 600 of the coil substrate 6. Any one of the first blocking portion 610 and the second blocking portion 620 directly faces the inner surface of the housing 1. On the contrary, between the outer peripheral surface of the main body portion 600 of the coil substrate 6 and the inner surface of the housing 1, there are the base end portion 73 of the connecting portion 71 of the FPC 7 and the portion where the connecting portion 71 falls down. The two blocking portions 610, 620 project outward from the portion where the FPC 7 does not exist on the outer periphery. The base end portion 73 faces the side surface of the main body portion 600 of the coil substrate 6 and is located inside the outer ends of the two blocking portions 610, 620. The first blocking portion 610 is provided between the other diagonal that is not the specified diagonal and the vicinity of the FPC 7 existing on the outer periphery, and the second blocking portion 620 is provided between the specified diagonal and the vicinity of the FPC 7 existing on the outer periphery. When the movable portion moves in the XY directions and rotates about the Z axis, the first blocking portion 610 and the second blocking portion 620 come into contact with the inner surface of the housing 1 earlier than any other part of the movable portion. Therefore, it is preferable that the first blocking portion 610 and the second blocking portion 620 are provided near the corners. The functions of the first blocking portion 610 and the second blocking portion 620 as blocking members can be exerted by only one of them. However, by adopting a structure in which the base end portion 73 of the FPC 7 is sandwiched between the first blocking portion 610 and the second blocking portion 620, it is possible to prevent the base end portion 73 from coming into contact with the inner surface of the housing 1 earlier than the first blocking portion 610 and the second blocking portion 620 during movement. In addition, on the rear surface of the second blocking portion 620, there is an electrical connection portion 621 electrically connected to the main body portion 70 of the FPC 7.

[0038] The bracket 4 is a frame-shaped body that is quadrilateral when viewed from the Z direction and has two pairs of wall portions 41 facing each other in the X and Y directions. At the corners where the wall portions 41 intersect, there are cutouts 43 whose inner sides are cut by four semi-arc-shaped cutouts. On the front surface of the wall portion 41, there are provided two-stage projecting table portions 480 that extend from the corners toward the centers of the sides. The table portion 480 has the foremost surface 481 at the center and the middle surfaces 482 on both sides thereof.

[0039] At the center of the foremost surface 481 of the table portion 480 of the wall portions 41 facing each other in the Y direction, there is provided a positioning projection 413, and on both sides of the positioning projection 413 in the X direction, there are provided two projecting portions 414. The positioning projection 413 stands directly up from a groove formed annularly around it. The foremost surface 481 of the table portion 480 of the wall portions 41 facing each other in the X direction is divided into two sides with a pit portion 420 at the center, and two projecting portions 414 are provided on both sides of the pit portion 420 in the Y direction. In addition, small projections 46 are respectively provided on the eight middle surfaces 482 of the table portion 480 of the wall portion 41.

[0040] As Figure 2As shown, the bracket 4 is covered by the housing 1. The housing 1 is box-shaped and has a front plate 10 that is quadrilateral when viewed from the Z direction and side plates 11 that extend rearward from the respective edges of the front plate 10. At the center of the front plate 10 of the housing 1 that covers the front side of the bracket 4, a rectangular through-hole 19 is provided. 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 housed in the bracket 4, the front side of the AF motor 102 is exposed from the through-hole 19. On the front plate 10, recessed portions 180 that are recessed rearward are provided at the central positions of the respective sides of the quadrilateral. On each of the recessed portions 180, two through-holes 14 are provided along the side portions. Positioning holes 13 are also provided in the recessed portions 180 on the +X side and the -X side, and the positioning holes 13 are located exactly in the middle between the two through-holes 14.

[0041] The positioning protrusion 413 of the bracket 4 is fitted into the positioning hole 13 of the front plate 10 of the housing 1. At this time, the rear surfaces of the table portion 480 and the recessed portion 180 are in contact, and it is difficult for the rear surface of the recessed portion 180 to float relative to the table portion 480 through the groove around the positioning protrusion 413. The protrusion portion 414 of the bracket 4 is inserted into the through-hole 14 of the front plate 10 of the housing 1 and fixed by hot riveting. As Figure 5 shown, the width of the front protrusion portion 414 of the through-hole 14 in the protrusion portion 414 is wider than the width of the through-hole 14, so it is difficult for the bracket 4 to fall off from the housing 1. The wider width corresponds to a larger diameter in the case where the cross-section after hot riveting is circular. In addition, the front end of the protrusion portion 414 is located at a position rearward of the front plate 10 of the portion adjacent to the recessed portion 180.

[0042] As Figure 4 and Figure 8 shown, on the inner side surface of the wall portion 41 of the bracket 4, an eaves portion 45 is provided. The eaves portion 45 is provided with a first protrusion portion that protrudes inward from the rear end of the inner side surface of the wall portion 41 and protrudes rearward from its inner end. The AF motor 102 is housed in the space surrounded by the inner side surface of the wall portion 41 and the front surface of the eaves portion 45 in the bracket 4. The outer surface of the AF motor 102 is adhesively fixed to the inner side surface of the wall portion 41.

[0043] The rear surface of the wall portion 41 of the bracket 4 is adhesively 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 face each other with a gap therebetween. 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, and further forms the same plane. The corner portion between the outer side surface and the rear surface of the bracket 4, which is the adhesive surface adhered to the magnet 5, is chamfered and provided with an inclined surface 453. In addition, the corner portion between the front surface and the outer side surface of the magnet 5, which is the adhesive surface adhered to the bracket 4, is chamfered and provided with an inclined surface 52. The adhesive between the wall portion 41 and the magnet 5 in the contact surface is squeezed into these chamfered portions to form an adhesive accumulation portion. That is, by supplying a sufficient amount of adhesive between the rear surface of the bracket 4 and the front surface of the magnet 5, the excess adhesive can be accommodated in the space formed by the two inclined surfaces 453 and 52. However, the exposure of the adhesive does not extend beyond the outer side surfaces of the bracket 4 and the magnet 5 to the outside. In addition, an adhesive is sandwiched between the outer side surface facing the first protrusion 451 and the inner side surface of the magnet 5, and the magnet 5 is also adhesively fixed by the first protrusion 451. In addition, the magnet 5 has two peripheral end surfaces 51 that intersect with the front surface and the outer side surface, and the bracket 4 has two second protrusions 452 that protrude rearward from the rear surface and sandwich the magnet 5. An adhesive is sandwiched between each peripheral end surface 51 and the opposing surface of the second protrusion 452 opposing the peripheral end surface 51, and the magnet 5 is also adhesively fixed by the second protrusion 452. In addition, as Figure 5 shown, at the position where the magnet 5 is adhesively fixed to the rear surface of the bracket 4, there is a recessed adhesive accumulation portion, that is, a groove 454, which is recessed forward.

[0044] In the bracket 4, the portions except for the corners on the +X+Y side and the -X-Y side are surrounded by the connecting portion 71 of the FPC 7. The corners on the +X+Y side and the -X-Y side of the bracket 4 are not surrounded by the connecting portion 71 and are exposed to the outside thereof.

[0045] As Figure 3 and Figure 4 shown, the support plate spring 3 is substantially L-shaped. Round holes are provided at the base end portion of the support plate spring 3 and at the front end portion that branches off from here and extends at a right angle.

[0046] At the middle cross-section 482 of the table portion 480 of the bracket 4, the front end portion of the support plate spring 3 is fixed. The small protrusion 46 on the middle cross-section 482 of the table portion 480 is inserted into the round hole at the front end portion of the support plate spring 3. The base end portion of the support plate spring 3 is in a floating state on the front side of the notch 43 of the bracket 4. At the four corners of the coil substrate 6, there are round holes at positions corresponding to the round holes at the front end portion of the support plate spring 3.

[0047] The suspension wire 2 is suspended between the round hole at the base end of the support plate spring 3 and the round holes of the coil substrate 6 within the cutout 43 of the support 4. That is, the front end of the suspension wire 2 is inserted and soldered to the round hole at the base end of the support plate spring 3, and the rear end is inserted and soldered to the round holes at the four corners of the coil substrate 6. Additionally, at the respective corners on the specified diagonal, i.e., the +X+Y side and the X-Y side, exposed from the FPC 7, the end side surfaces, i.e., the peripheral end surfaces 51, facing the tops of the respective corners of the two magnets 5 form opposing surfaces that are perpendicular to each other. The respective peripheral end surfaces 51 and the front side surface, i.e., 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 damping adhesive. The spanned peripheral end surfaces 51 are the peripheral end surface 51 of the +Y side magnet 5 facing the +X direction, the peripheral end surface 51 of the -Y side magnet 5 facing the -X direction, the peripheral end surface 51 of the +X side magnet 5 facing the +Y direction, and the peripheral end surface 51 of the -X side magnet 5 facing the -Y direction. Therefore, damping effects can be obtained in both the X and Y directions.

[0048] The above are the detailed configurations of this embodiment. The optical component driving device 100 of this embodiment includes: a frame-shaped support 4 that houses the AF motor 102 as a lens device; a magnet 5 whose front surface is adhesively fixed to the rear surface of the support 4; and a movable part that has a holding part for holding the image sensor 107 and is swingably supported at a position behind the AF motor 102. The outer side surface of the support 4 is parallel to the outer side surface of the magnet 5, and an inclined surface 453 is provided at the corner of the rear surface of the support 4 and the outer side surface of the support 4. Therefore, a sufficient amount of adhesive can be supplied between the rear surface of the support 4 and the front surface of the magnet 5, and the excess adhesive can be accommodated in the space formed by the inclined surface 453. Thereby, an optical component driving device 100 with high adhesive strength between the support 4 and the magnet 5 can be provided.

[0049] Additionally, in the above embodiment, it is also possible that the peripheral end surfaces 51 facing the corners of the +X-Y side and the -X-Y side and the front surface of the coil substrate 6 are not spanned by the viscoelastic resin. Additionally, it is not necessary for the spanned part to be the peripheral end surface 51. For example, it can also be the surface facing the top of the corner of the second protruding part 452 of the support 4, etc. In this case, the second protruding part 452 can also extend to a position behind the illustrated position. Additionally, the movable part to be spanned does not have to be the coil substrate 6. For example, the FPC 7 can also be provided on the front side of the coil substrate 6, and the FPC 7 can be spanned.

[0050] In addition, in the above-described embodiment, the protrusions 414 of the bracket 4 and the through-holes 14 of the housing 1 do not necessarily need to be provided in two on each side of the through-hole 19. They can be provided only on two opposite sides, or one can be provided on each side or three or more can be provided on each side. Additionally, preferably, the number of protrusions 414 on each side is the same on one pair of opposite sides, but the number of protrusions 414 can also be different between different pairs of opposite sides.

[0051] Furthermore, in the above-described embodiment, for the fixing of the protrusions 414 of the bracket 4 to the through-holes 14 of the housing 1, riveting and an adhesive can be used simultaneously, and the housing 1 and the bracket 4 can be bonded through the adhesive. In this case, it is sufficient to sandwich the adhesive between the front surface of the bracket 4 and the rear surface of the front plate 10 of the housing 1.
