[0007] Technical Problem to be Solved by the Invention

[0008] In a conventional optical unit such as those in Patent Documents 1 and 2, which includes a fixed body, a movable body provided with a lens unit, and a gimbal mechanism that supports the movable body so as to be rotatable relative to the fixed body about an axis of rotation in a direction intersecting the optical axis direction, the fixed body and the movable body are connected to the gimbal mechanism via other components. For example, in the optical unit of Patent Document 1, the fixed body and the movable body are connected to the gimbal mechanism via a thrust receiving component. In addition, in the optical unit of Patent Document 2, the movable body and the gimbal mechanism are connected via a first support component, and the fixed body and the gimbal mechanism are connected via a second support component.

[0009] However, in a structure where the fixed body and the movable body are connected to the gimbal mechanism via other components as in the optical units of Patent Documents 1 and 2, in addition to increasing the size of the other components, it is also necessary to provide areas for bonding or welding the other components to the fixed body and the movable body. Therefore, the connection portion between the fixed body and the movable body and the gimbal mechanism has a tendency to become larger, and there is a problem of the enlargement of the optical unit.

[0010] Technical solution for solving technical problems

[0011] Accordingly, the present invention provides an optical unit, comprising: a fixed body; a movable body provided with a lens unit; and a gimbal mechanism that supports the movable body so as to be rotatable relative to the fixed body about an axis of rotation in a direction intersecting the optical axis direction. The gimbal mechanism has: a fixed-body-side leg portion connected to the fixed body; and a movable-body-side leg portion connected to the movable body. At least one of the connection between the fixed body and the fixed-body-side leg portion and the connection between the movable body and the movable-body-side leg portion is directly connected without passing through other components.

Detailed Description of the Invention

[0025] Hereinafter, the optical unit 1 according to an embodiment of the present invention will be described using Figures 1 to 9 In each figure, the Z-axis direction is the optical axis direction, the X-axis direction is the direction intersecting the optical axis AX, in other words, the deflection axis direction, and the Y-axis direction is the direction intersecting the optical axis AX, in other words, the pitching axis direction. Further, the direction in which the arrow in the Z-axis direction points, that is, the +Z direction, is the subject side direction, and the direction opposite to the direction in which the arrow points, that is, the -Z direction, is the direction opposite to the subject side, the opposite side of the subject. In addition, in the present specification, the direction intersecting the Z-axis direction is defined as the width direction, and both the X-axis direction and the Y-axis direction correspond to one direction in the width direction.

[0026] The optical unit 1 of the present embodiment includes: a movable body 20 having a lens unit 22; and a fixed body 10 surrounding the movable body 20 in a circumferential direction intersecting the optical axis direction (Z-axis direction) of the lens unit 22. Further, the optical unit 1 of the present embodiment includes a gimbal mechanism 30 that supports the movable body 20 so as to be rotatable about axes intersecting the optical axis direction (X-axis direction and Y-axis direction) with respect to the fixed body 10. Moreover, the optical unit 1 of the present embodiment includes a drive unit 60 having a coil 61 disposed on the fixed body 10 and magnets 62 (magnets 62A and 62B) disposed at positions opposed to the coil 61 (coils 61A and 61B) in the movable body 20. In addition, when viewed from the optical axis direction, the coil 61 is disposed inside a flexible printed circuit board 63 mounted on the fixed body 10.

[0027] ​<Overall Structure of Optical Unit>

[0028] First, the overall structure of the optical unit 1 of this embodiment will be described. The optical unit 1 of this embodiment can preferably be used for cameras, smartphones, etc. This is because the optical unit 1 of this embodiment can be configured compactly, and cameras and smartphones can be configured compactly. However, the optical unit 1 of this embodiment is not limited to cameras and smartphones, and can be used for various devices without particularly limiting the use.

[0029] The optical unit 1 of this embodiment includes a movable body 20, and the movable body 20 includes a lens unit 22 provided with a lens or the like. The movable body 20 has a lens unit 22 and a cage 21 that surrounds the movable body 20 in the circumferential direction intersecting the optical axis direction (Z-axis direction) of the lens unit 22. In addition, the optical unit 1 of this embodiment includes a fixed body 10 that covers the lens unit 22 in a state where a part of the lens unit 22 is exposed from the +Z direction. The fixed body 10 has a frame portion 11; a metal housing 12 that is housed in the frame portion 11 and surrounds the movable body 20 in the circumferential direction; and a resin housing 13 that is installed outside the metal housing 12. In addition, the optical unit 1 of this embodiment includes a gimbal mechanism 30 between the movable body 20 and the fixed body 10. The gimbal mechanism 30 has a fixed-body-side leg portion 30A connected to the fixed body 10, a movable-body-side leg portion 30B connected to the movable body 20, and a flat plate portion 30C provided with the fixed-body-side leg portion 30A and the movable-body-side leg portion 30B. The gimbal mechanism 30 has elasticity and supports the movable body 20 so as to be rotatable relative to the fixed body 10 about the X-axis direction and the Y-axis direction as rotation axes.

[0030] <Movable Body>

[0031] The movable body 20 is substantially rectangular parallelepiped. When viewed from the optical axis direction, the lens unit 22 is held inside the cage 21 and is configured such that the forming portion of the lens protrudes from the +Z-direction surface of the cage 21. In addition, a magnet 62A as a magnet 62 is provided on the side surface of the cage 21 in the +X direction, and the magnet 62 constitutes a drive unit 60 that makes the movable body 20 movable relative to the fixed body 10. In addition, a magnet 62B as a magnet 62 constituting the drive unit 60 is provided on the side surface of the cage 21 in the +Y direction. Here, the magnet 62A and the magnet 62B have the same structure. In addition, the magnet 62A and the magnet 62B can also be regarded as a part of the movable body 20.

[0032] <Fixed Body>

[0033] The fixed body 10 is substantially rectangular parallelepiped. The fixed body 10 has a metal housing 12 with a resin housing 13 installed inside the frame portion 11. Moreover, when viewed from the optical axis direction, the movable body 20 is arranged inside the metal housing 12. Here, asFigure 3 and Figure 4 As shown in Figure 3 and Figure 4 , a housing portion 14 is constituted by a metal housing 12 and a resin housing 13. In addition, coils 61 constituting a drive unit 60 are provided on the side surfaces of the resin housing 13 on the +X direction side and the +Y direction side. These coils 61 are arranged at positions opposed to magnets 62A and 62B. Here, a coil 61A at a position of the coil 61 opposed to the magnet 62A and a coil 61B at a position of the coil 61 opposed to the magnet 62B have the same structure.

[0034] <Gimbal mechanism>

[0035] The gimbal mechanism 30 has: a flat plate portion 30C which has a circular hole portion through which a lens forming portion of the lens unit 22 passes and has a rectangular outer shape; and a fixed body side leg portion 30A and a movable body side leg portion 30B which serve as connection portions to the fixed body 10 and the movable body 20. The fixed body side leg portion 30A and the movable body side leg portion 30B are formed at the four corners of the rectangular flat plate portion 30C, and two connection portions on the diagonal line, that is, the fixed body side leg portion 30A is rotatably connected to the fixed body 10, and two connection portions on the other diagonal line, that is, the movable body side leg portion 30B is rotatably connected to the movable body 20. In addition, details of the connection portion between the fixed body 10 and the fixed body side leg portion 30A and the connection portion between the movable body 20 and the movable body side leg portion 30B will be described later.

[0036] In addition, the optical unit 1 of the present embodiment is structured such that the movable body 20 can be rotated relative to the fixed body 10 in the yaw axis direction and the pitch axis direction by the gimbal mechanism 30. However, an additional mechanism different from the gimbal mechanism 30 or the like can be further provided to enable the movable body 20 to be rotated relative to the fixed body 10 in the roll direction.

[0037] <Drive unit>

[0038] Next, the drive unit 60 will be described. As described above, the magnets 62A and 62B have the same structure, and the two coils 61A and 61B arranged at positions opposed to the magnets 62A and 62B have the same structure. The optical unit 1 of the present embodiment has a pitch axis rotation mechanism constituted by the magnet 62A and the coil 61A and a yaw axis rotation mechanism constituted by the magnet 62B and the coil 61B as the drive unit 60. However, it is not limited to such a structure, and it may be a structure having only any one of the pitch axis rotation mechanism and the yaw axis rotation mechanism. Moreover, a roll axis rotation mechanism capable of rotating the movable body 20 relative to the fixed body 10 can be provided.

[0039] <Connection portions of the fixed body and the movable body to the gimbal mechanism>

[0040] Next, the connection portions between the fixed body 10 and the fixed body side leg portion 30A, and between the movable body 20 and the movable body side leg portion 30B will be described. In addition, there are two connection portions between the fixed body 10 and the fixed body side leg portion 30A, and there are also two connection portions between the movable body 20 and the movable body side leg portion 30B, but they all have the same structure. Therefore, in the following description of the connection portions of the fixed body 10 and the movable body 20 with the gimbal mechanism 30, the fixed body 10 can be replaced with the movable body 20, and the fixed body side leg portion 30A can be replaced with the movable body side leg portion 30B. Moreover, the movable body 20 can be replaced with the fixed body 10, and the movable body side leg portion 30B can be replaced with the fixed body side leg portion 30A.

[0041] As Figure 3 and Figure 4 shown, a convex portion 31 protruding inward is provided on the fixed body side leg portion 30A of the gimbal mechanism 30. In addition, when the gimbal mechanism 30 is connected to the fixed body 10, a concave portion 81 recessed inward is provided at the position of the connection surface 12A of the fixed body 10 where the convex portion 31 is disposed (see Figure 5 ). Similarly, a convex portion 31 protruding inward is provided on the movable body side leg portion 30B of the gimbal mechanism 30. In addition, when the gimbal mechanism 30 is connected to the movable body 20, a concave portion 81 recessed inward is provided at the position of the connection surface 21A of the movable body 20 where the convex portion 31 is disposed (refer to Figures 6 to 8 ).

[0042] By configuring the fixed body 10, the movable body 20, and the gimbal mechanism 30 in this way, in each of the corresponding convex portion 31 and concave portion 81, for example, as Figure 7 shown, the convex portion 31 engages with the concave portion 81. In addition, as Figure 7 shown, when the gimbal mechanism 30 is connected to the movable body 20, the connection surface 21A of the movable body side leg portion 30B with respect to the movable body 20 is inserted from the outside, and at this time, the pressing force G is applied through the elasticity of the movable body side leg portion 30B. Similarly, although not shown, when the gimbal mechanism 30 is connected to the fixed body 10, the connection surface 12A of the fixed body side leg portion 30A with respect to the fixed body 10 is inserted from the outside, and at this time, the pressing force G is applied through the elasticity of the fixed body side leg portion 30A. By adopting such a structure, the connection between the fixed body 10 and the fixed body side leg portion 30A, and the connection between the movable body 20 and the movable body side leg portion 30B are directly connected without passing through other components.

[0043] Here, once summarized, the optical unit 1 of the present embodiment includes: a fixed body 10; a movable body 20 provided with a lens unit 22; and a gimbal mechanism 30 that supports the movable body 20 so as to be rotatable relative to the fixed body 10 about rotation axes in the X-axis direction and the Y-axis direction that intersect the optical axis direction. Here, the gimbal mechanism 30 has a fixed-body-side leg portion 30A connected to the fixed body 10 and a movable-body-side leg portion 30B connected to the movable body 20.

[0044] Moreover, the connection between the fixed body 10 and the fixed-body-side leg portion 30A and the connection between the movable body 20 and the movable-body-side leg portion 30B are directly connected without passing through other components such as a thrust-bearing component. In other words, the optical unit 1 of the present embodiment is configured such that the gimbal mechanism 30 can be rotatably supported relative to the fixed body 10 about an axis intersecting the optical axis direction without using other components, and the gimbal mechanism 30 can be rotatably supported relative to the movable body 20 about an axis intersecting the optical axis direction without using other components. That is, "directly connected without passing through other components" can be rephrased as "connected without using other components".

[0045] As in the optical unit 1 of the present embodiment, at least one of the connection between the fixed body 10 and the fixed-body-side leg portion 30A and the connection between the movable body 20 and the movable-body-side leg portion 30B is directly connected without passing through other components. Thus, at the connection portion between the fixed body 10 and the movable body 20 and the gimbal mechanism 30, it is not necessary to separately prepare connection components (such as a thrust-bearing component) for connecting the fixed body 10 and the movable body 20 to the gimbal mechanism 30.

[0046] For example, it is not necessary to separately prepare connection components such as a thrust-bearing component, thereby enabling a reduction in the number of components and a reduction in the connection processes of the connection components. Moreover, since the connection portion can be miniaturized, the optical unit 1 can be miniaturized.

[0047] In addition, if a structure of separately preparing connection components is adopted, there may be cases where the connection components are bonded or welded to the connection surfaces 12A and 21A, for example. However, by adopting the structure of the present embodiment, the regions required for bonding or welding the connection components to the connection surfaces 12A and 21A can be removed from the connection surfaces 12A and 21A, and the connection surfaces 12A and 21A can be reduced in size. Moreover, thereby, in particular, miniaturization of the optical unit 1 can be achieved. In addition, the connection surfaces (connection surfaces 12A and 21A) for connecting the connection components can be made of metal or resin, for example, and there is no particular limitation on the raw material.

[0048] In addition, in the optical unit 1 of the present embodiment, both the connection between the fixed body 10 and the fixed-body side leg portion 30A and the connection between the movable body 20 and the movable-body side leg portion 30B are directly connected without passing through other components. By adopting such a structure, it is possible to miniaturize both the connection portion between the fixed body 10 and the gimbal mechanism 30 and the connection portion between the movable body 20 and the gimbal mechanism 30. In particular, miniaturization of the optical unit 1 can be achieved.

[0049] However, the present invention is not limited to such a structure. As long as only one of the connection between the fixed body 10 and the fixed-body side leg portion 30A and the connection between the movable body 20 and the movable-body side leg portion 30B is directly connected without passing through other components, it is sufficient. Moreover, when there are a plurality of connection portions between the fixed body 10 and the gimbal mechanism 30 and between the movable body 20 and the gimbal mechanism 30, in at least one of them, the connection between the fixed body 10 and the fixed-body side leg portion 30A and the connection between the movable body 20 and the movable-body side leg portion 30B may be directly connected without passing through other components.

[0050] In addition, as Figure 7 shown, etc., in the optical unit 1 of the present embodiment, the movable body 20 and the movable-body side leg portion 30B are connected by the convex portion 31 and the concave portion 81 that engages with the convex portion 31. Similarly, in the optical unit 1 of the present embodiment, the fixed body 10 and the fixed-body side leg portion 30A are also connected by the convex portion 31 and the concave portion 81 that engages with the convex portion 31. Thus, a structure in which at least one of the connection between the fixed body 10 and the fixed-body side leg portion 30A and the connection between the movable body 20 and the movable-body side leg portion 30B is connected by the convex portion 31 and the concave portion 81 that engages with the convex portion 31 is preferable.

[0051] This is because by adopting such a structure, the convex portion 31 and the concave portion 81 can be simply formed, and the fixed body 10 and the movable body 20 and the gimbal mechanism 30 can easily slide in the convex portion 31 and the concave portion 81, making it easy for the movable body 20 to rotate relative to the fixed body 10. However, it is not limited to such a structure. For example, a cylindrical protrusion may be provided instead of the convex portion 31, and a round hole for inserting the protrusion may be formed instead of the concave portion 81.

[0052] In addition, in the optical unit 1 of the present embodiment, a part of the flat fixed-body side leg portion 30A and the movable-body side leg portion 30B is deformed to form the convex portion 31. Therefore, the number of components in the connection portion between the fixed body 10 and the movable body 20 and the gimbal mechanism 30 associated with forming the convex portion 31 can be reduced.

[0053] However, it is not limited to such a structure. For example, it may also be a structure in which spherical members or the like are welded or adhered to the fixed body side leg portion 30A and the movable body side leg portion 30B in a flat plate shape. By adopting a structure in which spherical members or the like are welded or adhered to the fixed body side leg portion 30A and the movable body side leg portion 30B, it is possible to easily increase the protruding amount into the concave portion 81, and the convex portion 31 can be firmly formed, so that the pressing force G can be increased, and the supporting force when the gimbal mechanism 30 supports the fixed body 10 and the movable body 20 can be enhanced.

[0054] In addition, in the optical unit 1 of the present embodiment, a convex portion 31 is provided on the fixed body side leg portion 30A and a concave portion 81 is provided on the fixed body 10, and a convex portion 31 is provided on the movable body side leg portion 30B and a concave portion 81 is provided on the movable body 20. In this way, it is preferably satisfied that at least one of the following is provided: a convex portion 31 is provided on the fixed body side leg portion 30A and a concave portion 81 is provided on the fixed body 10, and a convex portion 31 is provided on the movable body side leg portion 30B and a concave portion 81 is provided on the movable body 20. This is because by adopting such a structure, the connection portion between the fixed body 10 and the movable body 20 and the gimbal mechanism 30 can be simply formed.

[0055] However, it is not limited to such a structure. It may be a structure in which a concave portion is provided on the fixed body side leg portion 30A and a convex portion is provided on the fixed body 10, or a structure in which a concave portion is provided on the movable body side leg portion 30B and a convex portion is provided on the movable body 20. By adopting such a structure, the connection becomes simple when connecting the fixed body 10 and the movable body 20 to the gimbal mechanism 30.

[0056] Specifically, when connecting the fixed body 10 and the gimbal mechanism 30, the gimbal mechanism 30 is moved relative to the fixed body 10 in the -Z direction for connection. At this time, the convex portion 31 of the fixed body side leg portion 30A and the protruding portion 32 described later move in a state of being in contact with the connection surface 12A. By adopting a structure in which a concave portion is provided on the fixed body side leg portion 30A and a convex portion is provided on the fixed body 10, the moving distance in this contact state and the pressure associated with this movement can be reduced.

[0057] Similarly, when connecting the movable body 20 and the gimbal mechanism 30, the gimbal mechanism 30 is moved relative to the movable body 20 in the -Z direction for connection. At this time, the convex portion 31 of the movable body side leg portion 30B and the protruding portion 32 described later move in a state of being in contact with the connection surface 21A. By adopting a structure in which a concave portion is provided on the movable body side leg portion 30B and a convex portion is provided on the movable body 20, the moving distance in its contact state and the pressure associated with this movement can be reduced.

[0058] In addition, as Figures 3 to 6As shown, in the optical unit 1 of the present embodiment, on the fixed-body side leg portion 30A and the movable-body side leg portion 30B, there are provided protruding portions 32 that protrude inward, and on the connection surface 12A of the fixed body 10 and the connection surface 21A of the movable body 20, there are provided hole portions 82 into which the protruding portions 32 are fitted. In this way, it is preferable that at least one of the connection between the fixed body 10 and the fixed-body side leg portion 30A and the connection between the movable body 20 and the movable-body side leg portion 30B is connected not only by the convex portion 31 and the concave portion 81 but also by the protruding portion 32 and the hole portion 82 into which the protruding portion 32 is fitted. This is because by connecting not only by the convex portion 31 and the concave portion 81 but also by the protruding portion 32 and the hole portion 82, the gimbal mechanism 30 can be prevented from detaching from the fixed body 10 and the movable body 20.

[0059] Moreover, in the optical unit 1 of the present embodiment, as Figure 5 , Figure 6 and Figure 8 etc. show, around the convex portion 31 and the concave portion 81, there are provided a protruding portion 32A, a protruding portion 32B, and a protruding portion 32C as the protruding portion 32, and a hole portion 82A, a hole portion 82B, and a hole portion 82C as the hole portion 82. In this way, it is preferable that a plurality of the protruding portion 32 and the hole portion 82 are provided around the convex portion 31 and the concave portion 81. This is because by adopting such a structure, the gimbal mechanism 30 can be particularly appropriately prevented from detaching from the fixed body 10 and the movable body 20.
