Embodiments of the present invention will be described below with reference to the drawings.

< embodiment 1 >

As shown in fig. 1, in embodiment 1, a camera apparatus 100 is mounted on a smartphone 101. The camera device 100 includes: an AF motor 15 as an optical member having a lens body 18 and an image sensor 19 that photoelectrically converts light transmitted through the lens body 18; and an optical component tilting device 1 for holding the AF motor 15 to tilt it. AF is a shorthand to Autofocus.

Hereinafter, the optical axis direction along the optical axis of the lens body 18 is appropriately referred to as the Z direction, one direction orthogonal to the Z direction is appropriately referred to as the X direction, and a direction orthogonal to both the Z direction and the X direction is appropriately referred to as the Y direction. The + Z side, which is the object side, of the optical axis of the lens body 18 is referred to as the upper side, and the-Z side, which is the opposite side, is referred to as the lower side.

The AF motor 15 incorporates a driving source for driving the lens body 18 and an image sensor 19 in the main body 17, and the lens body 18 protrudes from the upper side of the main body 17 to be exposed. The lens body 18 has a right circular light entrance part 16 on an upper end surface thereof. The image sensor 19 is fixed to the lower end surface of the main body 17 such that the light receiving part 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 as the optical axis direction. Examples of the drive source of the AF motor 15 include a magnet and a coil, a piezoelectric element, and a shape memory alloy, but are not limited thereto.

The optical component tilting 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 in which a lower plate portion 28 and an upper plate portion 29 are combined with each other on the bottom plate portion 20. Cover 25 is assembled to bottom plate 20 from the outside of lower plate 28 and upper plate 29. The plate spring 5 has an outer side portion 56, an inner side portion 54, and a gimbal spring portion 55. The outer portion 56 of the leaf spring 5 is sandwiched between 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 surface 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 plate spring 5, a magnet 9 and a coil 8 are arranged as a driving portion in each pair. The cover 25, the bottom plate 20, the lower plate 28, the upper plate 29, and the coil 8 in these parts form a fixed part, and the leaf spring 5, the optical component holding part 7, and the magnet 9 form a movable part that moves relative to the fixed part.

The details of the structure of each part are described below. As shown in fig. 2, the cover 25 has a box shape with one side opened. A through hole 250 is formed in the upper surface of the cover 25.

The bottom plate portion 20 has a substantially square shape corresponding to the cover 25. As shown in fig. 5, 6, 7, and 8, the soft magnetic member 3 is fixed to the upper surface of the bottom plate 20. The soft magnetic member 3 has: a substantially quadrangular ring-shaped bottom portion 30; a 1 st standing part 31 extending and standing inward from the center of each of the sides on the + X side and the X side in the inner circumference of the bottom part 30; and a 2 nd standing part 32 extending and standing inward from the center of each of the + Y side and the Y side. The coil 8 is wound around each of the 1 st and 2 nd

vertical portions

31 and 32. The 1 st rising portion 31 and the 2 nd rising portion 32 are disposed inside the winding of the coil 8. The coil 8 is wound in a counterclockwise direction, for example, when viewed from the + Z side, with the Z direction as a winding axis. The end faces of the tip end portions of the 1 st standing portion 31 and the 2 nd standing portion 32 and the surface on the + Z side of each coil 8 are substantially one surface, but the surface on the + Z side of each coil 8 may be located further upward, and the end faces of the tip end portions of the 1 st standing portion 31 and the 2 nd standing portion 32 may be located further upward.

The lower plate portion 28 and the upper plate portion 29 are hollow and substantially quadrangular. As shown in fig. 3, a through hole 290 is formed in the upper plate 29. The lower surface of the lower plate portion 28 is fixed to the periphery of the bottom portion 30 of the soft magnetic member 3 in the upper surface of the bottom plate portion 20. The lower peripheral surface 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 29 is fixed to the peripheral upper surface of the outer portion 56 of the leaf spring 5. Thereby, the plate spring 5 is kept in a floating state with respect to the bottom plate portion 20.

The plate spring 5 is formed of a soft magnetic material having elasticity. The plate spring 5 supports the optical component holding portion 7 to be movable obliquely with respect to the fixed portion. The plate spring 5 is located at a height between the light incident portion 16 of the AF motor 15 and the light receiving portion. The plate spring 5 has two outer portions 56 and inner portions 54, and a gimbal spring portion 55 connecting these portions. The two outer side portions 56 have a shape in which an inner corner of the shape of "コ" is rounded into an arc. The two outer portions 56 are disposed apart to the + X side and the-X side, and have a substantially square outer shape corresponding to the peripheral edges of the lower plate portion 28 and the upper plate portion 29 as a whole. The outer portion 56 is recessed twice outward toward the center of the inner end as a recess 560.

The inner portion 54 has a rectangular frame shape. The inner portion 54 has a projection 540 on the outer side edge in the X direction. The inner side 54 is provided with a 1 st mounting portion 61 for mounting the magnet 9 at an inner end in the X direction. The 1 st attachment portion 61 is formed by bending a rectangular piece protruding from the center of the inner end side in the X direction of the inner portion 54 toward the side opposite to the convex portion 540 toward the-Z side. The 1 st mounting portion 61 is formed to be substantially flush with the end edge thereof. In embodiment 1, the bent tip is bent further outward in the X direction to prevent the magnet 9 from falling, which will be described later.

A magnet 9 is disposed in the 1 st mounting portion 61. The magnet 9 has a rectangular parallelepiped shape having an opposing surface 95 opposing the coil 8 and an opposing surface 96 opposite thereto. The opposite surfaces 96 of the magnets 9 are attached to the 1 st mounting portion 61 and the inner portion 54, respectively, on the upper surfaces thereof. A portion of the upper side is located at the lower side of the convex part 540. In the present embodiment, the lower surface is also attached to the portion of the 1 st attaching portion 61 that is bent outward in the X direction. As shown in fig. 6, a lower portion of the magnet 9 in the 1 st mounting portion 61 and an upper portion of the coil 8 wound around the 1 st standing portion 31 oppose each other with a gap therebetween. In embodiment 1, the end face of the tip of the 1 st standing part 31 is located on the-Z side of the center of the magnet 9. The direction of the winding shaft of the coil 8 wound around the 1 st standing part 31 is orthogonal to the normal direction of the facing surface 95 of the magnet 9. The facing surface 95 of the magnet 9 is magnetized to have an N-pole, for example, and the opposite surface 96 is magnetized to have an S-pole. The upper side surface of the coil 8 faces the convex portion 540 together with the end surface of the tip end portion of the 1 st standing portion 31.

As shown in fig. 4 and 5, the gimbal spring portion 55 is formed in a ring shape between the outer portion 56 and the inner portion 54, and is coupled to the outer portion 56 at the ± X side by a coupling portion 551, and is coupled to the inner portion 54 at the ± Y side by a coupling portion 552. The portion of the gimbal spring portion 55 corresponding to the convex portion 540 of the inner portion 54 is expanded outward in the X direction as a curved portion 550 in a letter "コ". The bending portion 550 has a coupling portion 551 at the center thereof. The connection portion 551 is connected to the recess 560 of the outer portion 56.

The gimbal spring 55 has a 2 nd mounting portion 62 on the outer side edge in the Y direction. The 2 nd mounting portion 62 is formed by bending a rectangular piece protruding outward from the center of the outer end side in the Y direction of the gimbal spring portion 55 in the-Z direction. The 2 nd mounting part 62 is formed to protrude outward from the end edge. In embodiment 1, the bent tip is further bent inward in the Y direction, thereby preventing the magnet 9 from falling.

A magnet 9 is disposed in the 2 nd mounting portion 62. The opposite surface 96, the upper surface and the lower surface of the magnet 9 are attached to the corresponding surfaces of the 2 nd mounting portion 62. A part of the magnet 9 on the lower side in the 2 nd mounting portion 62 and a part of the coil 8 wound around the 2 nd standing portion 32 oppose each other with a gap therebetween. In embodiment 1, the end face of the distal end of the 2 nd standing part 32 is located on the-Z side of the center of the magnet 9. The direction of the winding shaft of the coil 8 wound around the 2 nd standing part 32 is orthogonal to the normal direction of the facing surface 95 of the magnet 9. The facing surface 95 of the magnet 9 is magnetized to have an N-pole, for example, and the opposite surface 96 is magnetized to have an S-pole. The upper side surface of the coil 8 faces the main body portion of the gimbal spring portion 55 together with the end surface of the distal end portion of the 2 nd standing portion 32.

As shown in fig. 4 and 5, a coupling portion 552 is provided at the center of the Y-direction inner side edge of the gimbal spring portion 55. The connecting portion 552 is connected to the outer edge of the inner portion 54 in the Y direction.

An optical component holding portion 7 is provided on the inner lower side of the inner portion 54. The optical component holding portion 7 has a box shape having an outer periphery corresponding to the inner portion 54. The upper end of the optical component holder 7 is fixed to the inner part 54. The optical component holding portion 7 surrounds the lower side of the AF motor 15 from the outside and the lower side.

As shown in fig. 3, the lens body 18 is exposed so as to protrude from the through hole 790 of the main body 17 of the AF motor 15, and the main body 17 is exposed from the through hole 290 of the upper plate 29. A gap is provided between the through hole 290 and the main body 17 so as not to hinder the tilting movement of the AF motor 15. As shown in fig. 2, the lens body 18 is also exposed so as to protrude from the through hole 250 of the cover 25.

When the coil 8 wound around the 1 st standing part 31 is energized, the 1 st standing part 31 becomes an electromagnet whose end face of the tip end part becomes a magnetic pole face. When a current flows so that the end face thereof becomes, for example, an N-pole, the magnet 9 generates a reaction force in the + Z direction and a reaction force in the-Z direction with respect to the facing surface 95, but the reaction force in the + Z direction is large, and therefore moves in the + Z direction. When a current flows so that the end face thereof becomes the S pole, an attractive force is generated on the magnet 9 with respect to the facing surface 95. In this way, the magnet 9 is moved in the-Z direction with a target position where the center position in the Z direction of the facing surface 95 coincides with the position in the Z direction of the end surface of the tip end portion of the 1 st upright portion 31 so that the attraction force in the + Z direction and the attraction force in the-Z direction are balanced. When a current flows so that a counter force is generated in the coil 8 wound around the 1 st standing portion 31, the connecting portion 552 deforms, and the movable portion swings about the axis of the Y axis. When the coil 8 wound around the 2 nd standing portion 32 is energized, a reaction force or an attraction force is similarly generated. When a current flows so that a counter force is generated in the coil 8 wound around the 2 nd standing portion 32, the connecting portion 551 deforms, and the movable portion swings about the X-axis.

The end face of the tip end of the 1 st standing part 31 and the end face of the tip end of the 2 nd standing part 32 face the plate spring 5 formed of a soft magnetic material. Therefore, the magnetic force of the 1 st standing part 31 and the 2 nd standing part 32 as the electromagnet can be increased. Further, since the opposite surface 96 of the magnet 9 is attached to the plate spring 5, the magnetic force of the magnet 9 can be increased.

The above is the details of embodiment 1. The optical component tilting and moving device 1 according to embodiment 1 includes a fixed portion, a moving portion having an optical component holding portion 7, a support portion for coupling and supporting the fixed portion and the moving portion, and a driving portion for driving the moving portion. Thus, the driving unit includes an electromagnet formed by providing the soft magnetic member 3 inside the winding of the coil 8, and a magnet 9 facing the electromagnet. Therefore, stronger magnetic force can act. Thus, according to embodiment 1, it is possible to provide the optical component tilting device 1, the camera device 100, and the electronic apparatus capable of securing a sufficient driving force of the movable portion.

In addition, as the optical component tilting device 1 according to embodiment 1, the supporting portion includes the plate spring 5 formed of a soft magnetic material, the driving portion includes the coil 8 and the magnet 9 having the facing surface 95 facing the coil 8, and the plate spring 5 is fixed to the facing surface 96 located on the opposite side of the facing surface 95 of the magnet 9. Therefore, the plate spring 5 has both the function of supporting the optical component holding portion 7 and the function of a yoke that increases the magnetic force of the magnet 9, and therefore, it is not necessary to dispose a yoke as another component near the magnet 9. Therefore, according to embodiment 1, it is possible to provide the optical component tilting device 1, the camera device 100, and the electronic apparatus, which can secure a sufficient driving force of the movable portion with a small number of parts.

In the optical component tilting device 1 according to embodiment 1, the supporting portion includes a plate spring 5 that supports the movable portion so as to be tiltable with respect to the fixed portion, the optical component includes a light incident portion 16 and a light receiving portion, and the plate spring 5 is located at a height between the light incident portion 16 and the light receiving portion. Therefore, according to embodiment 1, variation due to a difference in the posture of the thrust when the movable portion swings is less likely to occur. Therefore, according to embodiment 1, it is possible to provide the optical component tilting device 1, the camera device 100, and the electronic apparatus in which the maximum required thrust of the movable portion is small.

< embodiment 2 >

Embodiment 2 of the present invention will be described. As shown in fig. 13, 14, and 15, the optical component tilting device 1A according to embodiment 2 of the present invention is different from that of embodiment 1 in the structure in which the coil 8, the soft magnetic component 3, and the magnet 9 face each other.

In embodiment 2, the coil 8 and the magnet 9 are arranged so that the direction of the coil 8 around the winding shaft coincides with the normal direction of the facing surface 95 of the magnet 9. That is, the facing surface 95 of the magnet 9 in the 1 st mounting portion 61 faces the end surface of the 1 st standing portion 31 of the soft magnetic member 3. The opposite surface 96 is fixed to the-Z plate surface of the inner portion 54. The facing surface 95 is magnetized to have an N-pole, for example, and the opposite surface 96 is magnetized to have an S-pole.

Similarly, the facing surface 95 of the magnet 9 in the 2 nd mounting portion 62 faces the end surface of the distal end portion of the 2 nd standing portion 32 of the soft magnetic member 3. The opposite surface 96 is fixed to the-Z-side plate surface of the gimbal spring portion 55. The facing surface 95 is magnetized to the N-pole, for example, and the opposite surface 96 is magnetized to the S-pole. Since the plate spring 5 is formed of a soft magnetic material, the magnetic force of the facing surface 95 of the magnet 9 can be increased.

When a current flows through the coil 8 so that the end face of the tip end of the 1 st standing part 31 or the 2 nd standing part 32 becomes the N pole, a reaction force is generated in the facing surface 95 of the magnet 9, and the magnet 9 moves in the + Z direction. When a current flows through the coil 8 so that the end surface of the tip end of the 1 st standing part 31 or the 2 nd standing part 32 becomes the 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 a current flows so that a counter force is generated in the coil 8 wound around the 1 st standing portion 31, the connecting portion 552 deforms, and the movable portion swings about the axis of the Y axis. When a current flows so that a counter force is generated in the coil 8 wound around the 2 nd standing portion 32, the connecting portion 551 deforms, and the movable portion swings about the X-axis.

In the above-described

embodiments

1 and 2, the optical member may be a prism having an incident surface as a light incident portion, and a reflection surface and an emission surface as light receiving portions. In this case, the plate spring 5 may be disposed at the same position as the center of gravity of the movable portion in the Z direction.

In the above-described embodiment 1 and embodiment 2, the facing surface 95 of the magnet 9 may be magnetized to the S-pole, and the opposite surface 96 may be magnetized to the N-pole. The facing surface 95 and the facing surface 96 may be magnetized to have one magnetic pole, respectively. The coil 8 may be wound in the opposite direction to that of the first and

second embodiments

1 and 2, that is, in the clockwise direction when viewed from the + Z side.

The coil 8 is provided in the fixed portion, but may be provided in the movable portion, for example. In this case, the magnet 9 attached to the inner portion 54 of the leaf spring 5 is attached to the outer portion 56, for example. Although the optical component tilting mechanism has been described in the above-described

embodiments

1 and 2, the plate spring 5 may be a spring having an inner portion, an outer portion, and a plurality of arm portions connecting the inner portion and the outer portion. Therefore, by configuring the image sensor such that the fixed portion and the lens body are provided on the movable portion, the tilt movable device can be configured as a driving device capable of linearly driving the optical member. That is, the driving unit described in embodiment 1 and embodiment 2 may be applied to tilt (pivot) driving or linear driving.
