[0035] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0036] <First Embodiment>

[0037] like Figure 1 As shown, in the first embodiment, the camera device 100 is mounted in a smartphone 101. The camera device 100 includes: an AF motor 15 as an optical component, which includes a lens 18 and an image sensor 19 that performs photoelectric conversion on light passing through the lens 18; and an optical component tilting device 1 that holds the AF motor 15 and tilts it. AF is an abbreviation for Autofocus.

[0038] Hereinafter, the optical axis direction along the optical axis of the lens body 18 is appropriately referred to as the Z direction, a direction perpendicular to the Z direction is appropriately referred to as the X direction, and a direction perpendicular to both the Z direction and the X direction is appropriately referred to as the Y direction. In addition, the +Z side of the optical axis of the lens body 18, which is the subject side, is referred to as the upper side, and the opposite side, which is the -Z side, is referred to as the lower side.

[0039] The AF motor 15 has a driving source for driving a lens body 18 and an image sensor 19 built in its body 17, and the lens body 18 protrudes and is exposed from the upper side of the body 17. The upper end surface of the lens body 18 has a perfect circular light incident portion 16. The image sensor 19 is fixed to the lower end surface of the body 17 so that the light receiving portion of the image sensor 19 faces the lens body 18. The AF motor 15 drives the lens body 18 forward and backward in the Z direction, which is the optical axis direction. The driving source of the AF motor 15 can be a magnet, a coil, a piezoelectric element, a shape memory alloy, etc., but is not limited thereto.

[0040] The optical component tilting movable device 1 includes a housing 2, a leaf spring 5, and an optical component holding portion 7. The housing 2 includes a cover 25 and a portion formed by combining a lower plate portion 28 and an upper plate portion 29 on a bottom plate portion 20. The cover 25 is assembled to the bottom plate portion 20 from the outside of the lower plate portion 28 and the upper plate portion 29. The leaf spring 5 includes an outer portion 56, an inner portion 54, and a gimbal spring portion 55. The outer portion 56 of the leaf spring 5 is clamped by the upper surface of the lower plate portion 28 and the lower surface of the upper plate portion 29, and the optical component holding portion 7 that holds the side of the AF motor 15 is fixed to the inner portion 54 of the leaf spring 5. In the space between the bottom plate portion 20 and the leaf spring 5, pairs of magnets 9 and coils 8 as driving portions are arranged. The cover 25, the bottom plate portion 20, the lower plate portion 28, the upper plate portion 29, and the coil 8 of these portions form a fixed portion, and the leaf spring 5, the optical component holding portion 7, and the magnet 9 form a movable portion that moves relative to the fixed portion.

[0041] The following describes the structural details of each part. Figure 2 As shown, the cover 25 is in a box shape with one side open. A through hole 250 is provided on the upper surface of the cover 25.

[0042] The bottom plate 20 is in a substantially square shape corresponding to the cover 25. Figure 5 , Figure 6 , Figure 7 as well as Figure 8 As shown, the soft magnetic component 3 is fixed on the upper surface of the bottom plate 20. The soft magnetic component 3 has: a bottom 30 of a substantially quadrilateral ring shape; a first upright portion 31 extending and rising from the center of each side on the +X side and the X side of the inner circumference of the bottom 30 to the inner side; and a second upright portion 32 extending and rising from the center of each side on the +Y side and the Y side to the inner side. The coil 8 is wound around the first upright portion 31 and the second upright portion 32, respectively. The first upright portion 31 and the second upright portion 32 are arranged on the inner side of the winding of the coil 8. The coil 8 is wound in the counterclockwise direction when viewed from the +Z side, for example, with the Z direction as the winding axis. The end faces of the front end portions of the first upright portion 31 and the second upright portion 32 and the surface on the +Z side of each coil 8 are roughly the same surface, but the surface on the +Z side of each coil 8 may be further up, and the end faces of the front end portions of the first upright portion 31 and the second upright portion 32 may also be located further up.

[0043] The lower plate portion 28 and the upper plate portion 29 are hollow and generally quadrangular prism-shaped. Figure 3As shown, a through hole 290 is formed in the upper plate portion 29. The lower surface of the lower plate portion 28 is fixed to the periphery of the bottom 30 of the soft magnetic component 3 in the upper surface of the bottom plate portion 20. The lower surface of the peripheral edge of the outer portion 56 of the leaf spring 5 is fixed to the upper surface of the lower plate portion 28. The lower surface of the upper plate portion 29 is fixed to the upper surface of the peripheral edge of the outer portion 56 of the leaf spring 5. As a result, the leaf spring 5 is kept in a floating state relative to the bottom plate portion 20.

[0044] The leaf spring 5 is formed of a soft magnetic material having elasticity. The leaf spring 5 supports the optical component holding portion 7 so that it can tilt relative to the fixed portion. The leaf spring 5 is located at a height between the light incident portion 16 and the light receiving portion of the AF motor 15. The leaf spring 5 has two outer portions 56, an inner portion 54, and a gimbal spring portion 55 connecting them. The two outer portions 56 have a The inner corners of the letter are rounded into an arc shape. The two outer portions 56 are separated and arranged toward the +X side and the -X side, and as a whole, have a substantially square shape corresponding to the periphery of the lower plate portion 28 and the upper plate portion 29. The center of the outer portion 56 toward the inner end side is a concave portion 560, which is concave twice toward the outside.

[0045] The inner side portion 54 is in a rectangular frame shape. A convex portion 540 is provided at the outer end side of the inner side portion 54 in the X direction. A first mounting portion 61 for mounting the magnet 9 is provided at the inner end side of the inner side portion 54 in the X direction. The first mounting portion 61 is formed by bending a rectangular piece toward the -Z side, and the rectangular piece protrudes from the center of the inner end side of the inner side portion 54 in the X direction toward the side opposite to the convex portion 540. The first mounting portion 61 is formed in a manner that is substantially flush with its end side. In addition, in the first embodiment, the bent front end is further bent toward the outer side in the X direction to prevent the magnet 9 described later from falling.

[0046] The first mounting portion 61 is provided with a magnet 9. The magnet 9 is in the shape of a rectangular parallelepiped having an opposing surface 95 facing the coil 8 and an opposing surface 96 on the opposite side thereof. The upper side surface of the opposing surface 96 of the magnet 9 is mounted on the first mounting portion 61 and the inner portion 54, respectively. A portion of the upper side surface is located on the lower side of the protrusion 540. In addition, in the present embodiment, the lower side surface is also mounted on the portion of the first mounting portion 61 that is bent outward in the X direction. Figure 6 As shown, a lower portion of the magnet 9 in the first mounting portion 61 and an upper portion of the coil 8 wound on the first vertical portion 31 face each other with a gap therebetween. In the first embodiment, the end face of the front end portion of the first vertical portion 31 is located closer to the -Z side than the center of the magnet 9. The direction of the winding axis of the coil 8 wound on the first vertical portion 31 is orthogonal to the normal direction of the facing surface 95 of the magnet 9. In addition, the facing surface 95 of the magnet 9 is magnetized to the N pole, for example, and the opposite facing surface 96 is magnetized to the S pole. The upper side surface of the coil 8 faces the convex portion 540 together with the end face of the front end portion of the first vertical portion 31.

[0047] like Figure 4 as well as Figure 5 As shown in FIG. 1 , the gimbal spring portion 55 forms a ring between the outer portion 56 and the inner portion 54, and is connected to the outer portion 56 by a connecting portion 551 on the ±X side, and is connected to the inner portion 54 by a connecting portion 552 on the ±Y side. The portion of the gimbal spring portion 55 corresponding to the convex portion 540 of the inner portion 54 is formed as a curved portion 550, which is extended outward in the X direction. A connecting portion 551 is provided at the center of the curved portion 550. The connecting portion 551 is connected to the concave portion 560 of the outer portion 56.

[0048] A second mounting portion 62 is provided at the outer end of the gimbal spring portion 55 in the Y direction. The second mounting portion 62 is formed by bending a rectangular piece in the -Z direction, and the rectangular piece protrudes outward from the center of the outer end of the gimbal spring portion 55 in the Y direction. The second mounting portion 62 is formed to protrude outward from the end. In addition, in the first embodiment, the bent front end is further bent inward in the Y direction to prevent the magnet 9 from falling.

[0049] The second mounting portion 62 is provided with a magnet 9. The opposite surface 96, the upper side surface and the lower side surface of the magnet 9 are mounted on the corresponding surfaces of the second mounting portion 62, respectively. A lower portion of the magnet 9 in the second mounting portion 62 and an upper portion of the coil 8 wound on the second vertical portion 32 face each other with a gap therebetween. In the first embodiment, the end surface of the front end portion of the second vertical portion 32 is located closer to the -Z side than the center of the magnet 9. The direction of the winding axis of the coil 8 wound on the second vertical portion 32 is orthogonal to the normal direction of the opposite surface 95 of the magnet 9. In addition, the opposite surface 95 of the magnet 9 is magnetized to the N pole, for example, and the opposite surface 96 is magnetized to the S pole. The upper side surface of the coil 8 faces the main body of the gimbal spring portion 55 together with the end surface of the front end portion of the second vertical portion 32.

[0050] like Figure 4 as well as Figure 5 As shown, there is a connecting portion 552 at the center of the inner end side in the Y direction of the gimbal spring portion 55. The connecting portion 552 is connected to the outer end side of the inner portion 54 in the Y direction.

[0051] The optical component holding part 7 is provided at the inner lower part of the inner part 54. The optical component holding part 7 is in a box shape having an outer periphery corresponding to the inner part 54. The upper end of the optical component holding part 7 is fixed to the inner part 54. The optical component holding part 7 surrounds the lower side of the AF motor 15 from the outer side and the lower side.

[0052] like Figure 3As shown, the lens body 18 is exposed in a protruding manner from the through hole 790 of the body 17 of the AF motor 15, and the body 17 is exposed from the through hole 290 of the upper plate portion 29. A gap is provided between the through hole 290 and the body 17 so as not to hinder the tilting movement of the AF motor 15. Figure 2 As shown, the lens body 18 is exposed in a manner that also protrudes from the through hole 250 of the cover 25.

[0053] When the coil 8 wound on the first vertical portion 31 is energized, the first vertical portion 31 becomes an electromagnet with the end face of its front end portion serving as a magnetic pole face. When current flows so that its end face serves as an N pole, for example, the magnet 9 generates reaction forces in the +Z direction and the -Z direction with respect to its facing surface 95, but the reaction force in the +Z direction is larger, so it moves in the +Z direction. When current flows so that its end face serves as an S pole, an attractive force is generated in the magnet 9 with respect to the facing surface 95. In this way, the magnet 9 moves in the -Z direction with the goal of balancing the attractive forces in the +Z direction and the attractive forces in the -Z direction, with the center position of the facing surface 95 in the Z direction coinciding with the position of the end face of the front end portion of the first vertical portion 31 in the Z direction. When current flows so that a reverse force is generated in the coil 8 wound on the first vertical portion 31, the connecting portion 552 is deformed, and the movable portion swings around the Y axis. When the coil 8 wound in the second vertical portion 32 is energized, a reaction force or attraction force is similarly generated. When current flows in a manner that generates a reverse force on the coil 8 wound in the second vertical portion 32, the connecting portion 551 is deformed and the movable portion swings around the X-axis.

[0054] The end surface of the front end of the first vertical portion 31 and the end surface of the front end of the second vertical portion 32 are opposite to the leaf spring 5 formed of soft magnetic material. Therefore, the magnetic force of the first vertical portion 31 and the second vertical portion 32 as electromagnets can be increased. In addition, the opposite surface 96 of the magnet 9 is attached to the leaf spring 5, so the magnetic force of the magnet 9 can be increased.

[0055] The above are the details of the first embodiment. The optical component tilting movable device 1 as the first embodiment includes a fixed portion, a movable portion having an optical component holding portion 7, a supporting portion connecting and supporting the fixed portion and the movable portion, and a driving portion that drives the movable portion. Thus, the driving portion includes an electromagnet formed by providing a soft magnetic component 3 on the inner side of the winding of the coil 8 and a magnet 9 facing the electromagnet. Therefore, a stronger magnetic force can be exerted. Therefore, according to the first embodiment, an optical component tilting movable device 1, a camera device 100, and an electronic device that can ensure sufficient driving force for the movable portion can be provided.

[0056] In addition, as the optical component tilting movable device 1 of the present first embodiment, the support portion has a leaf spring 5 formed of a soft magnetic material, the driving portion has a coil 8 and a magnet 9 having an opposing surface 95 opposing the coil 8, and the leaf spring 5 is fixed to an opposing surface 96 located on the opposite side of the opposing surface 95 of the magnet 9. Therefore, the leaf spring 5 has both a function of supporting the optical component holding portion 7 and a function of a yoke that increases the magnetic force of the magnet 9, so it is unnecessary to arrange a yoke as another component near the magnet 9. Therefore, according to the present first embodiment, it is possible to provide an optical component tilting movable device 1, a camera device 100, and an electronic device that can ensure a sufficient driving force of the movable portion with a small number of parts.

[0057] In addition, as the optical component tilting movable device 1 of the first embodiment, the support portion has a leaf spring 5 that supports the movable portion so that it can tilt relative to the fixed portion, the optical component has a structure having a light incident portion 16 and a light receiving portion, and the leaf spring 5 is located at a height between the light incident portion 16 and the light receiving portion. Therefore, according to the first embodiment, it is difficult to cause deviation due to the posture difference of the thrust when the movable portion swings. Therefore, according to the first embodiment, it is possible to provide an optical component tilting movable device 1, a camera device 100, and an electronic device in which the maximum required thrust of the movable portion is small.

[0058] <Second Embodiment>

[0059] A second embodiment of the present invention will be described. Fig.13 , Fig.14 as well as Fig.15 As shown in FIG. 1 , the optical component tilting movable device 1A as the second embodiment of the present invention is different from the first embodiment in that the coil 8 and the soft magnetic member 3 and the magnet 9 are opposed to each other.

[0060] In the second embodiment, the coil 8 and the magnet 9 are arranged so that the winding axis direction of the coil 8 and the normal direction of the facing surface 95 of the magnet 9 are consistent. That is, the facing surface 95 of the magnet 9 in the first mounting portion 61 faces the end surface of the front end portion of the first standing portion 31 of the soft magnetic member 3. The opposite facing surface 96 is fixed to the plate surface on the -Z side of the inner portion 54. The facing surface 95 is magnetized to the N pole, for example, and the opposite facing surface 96 is magnetized to the S pole.

[0061] Similarly, the facing surface 95 of the magnet 9 in the second mounting portion 62 faces the end surface of the front end portion of the second upright portion 32 of the soft magnetic component 3. The opposite facing surface 96 is fixed to the plate surface on the -Z side of the gimbal spring portion 55. The facing surface 95 is magnetized to an N pole, for example, and the opposite facing surface 96 is magnetized to an S pole. The leaf spring 5 is formed of a soft magnetic material, so that the magnetic force of the facing surface 95 of the magnet 9 can be increased.

[0062] When current flows through the coil 8 so that the end surface of the front end of the first vertical portion 31 or the second vertical portion 32 becomes an N pole, a reaction force is generated on the facing surface 95 of the magnet 9, and the magnet 9 moves in the +Z direction. When current flows through the coil 8 so that the end surface of the front end of the first vertical portion 31 or the second vertical portion 32 becomes an S pole, an attractive force is generated on the facing surface 95 of the magnet 9, and the magnet 9 moves in the -Z direction. When current flows so that a reverse force is generated in the coil 8 wound on the first vertical portion 31, the connecting portion 552 is deformed, and the movable portion swings around the Y axis. When current flows so that a reverse force is generated in the coil 8 wound on the second vertical portion 32, the connecting portion 551 is deformed, and the movable portion swings around the X axis.

[0063] In the first and second embodiments, the optical component may be a prism having an incident surface as a light incident portion and a reflecting surface and an emitting surface as a light receiving portion. In this case, the leaf spring 5 may be further arranged at the same position as the center of gravity of the movable portion in the Z direction.

[0064] In the first and second embodiments, the facing surface 95 of the magnet 9 may be magnetized to the S pole, and the opposite facing surface 96 may be magnetized to the N pole. The facing surface 95 and the opposite facing surface 96 may be magnetized to one magnetic pole respectively. In addition, the coil 8 may be wound in the opposite direction to the first and second embodiments, that is, in the clockwise direction when viewed from the +Z side.

[0065] In addition, the coil 8 is provided in the fixed part, but it can also be provided in the movable part, for example. In this case, the magnet 9 mounted on the inner part 54 of the leaf spring 5 is mounted on the outer part 56, for example. In addition, in the above-mentioned first embodiment and second embodiment, it is described as an optical component tilting movable device, but for example, the leaf spring 5 can adopt a spring having an inner part, an outer part, and a plurality of arm parts connecting the inner part and the outer part. Therefore, by making the image sensor adopt a structure in which the fixed part and the lens body are provided on the movable part, it is also possible to make the tilting movable device adopt a driving device that can linearly drive the optical component. That is, the driving part described in the above-mentioned first embodiment and second embodiment can be applied to tilt (rotation) drive and can also be applied to linear drive.
