Disclosure of Invention
Technical problem to be solved by the invention
In the optical unit having the above-described structure in which the movable body including the optical module is supported so as to be rotatable with respect to the fixed body with respect to the rotation axis in the direction intersecting the optical axis direction of the optical module, the movable body is easily moved in the optical axis direction with respect to the fixed body, and when an optical device accommodating the optical unit is dropped or the like, there is a possibility that the movable body is dropped from the fixed body by a drop impact or the like, or a possibility that a component of the optical device collides with the optical module and is damaged. On the other hand, if a mechanism for suppressing the movable body from coming off the fixed body or the constituent members of the optical device from colliding with the optical module is provided, the optical unit tends to be enlarged by the mechanism. In this way, in the conventional optical unit having a structure in which the movable body including the optical module is supported so as to be rotatable with respect to the fixed body with respect to the rotation axis in the direction intersecting the optical axis direction of the optical module, it is difficult to achieve downsizing while suppressing the occurrence of defects in the case of dropping or the like of the optical device in which the optical unit is housed. Accordingly, an object of the present invention is to provide a compact optical unit which is less likely to cause defects even when an optical device is dropped or the like.
Technical proposal adopted for solving the technical problems
An optical unit according to the present invention is an optical unit to be housed in an optical device, comprising: a movable body provided with an optical module; and a fixed body that supports the movable body so as to be rotatable about a direction intersecting an optical axis direction of the optical module, the fixed body having an opening that opens in the optical axis direction, the movable body having a protruding portion from which the optical module protrudes to an outside of the fixed body, and a buffer being provided at a position facing a constituent member of the optical device in the optical axis direction at the protruding portion.
According to this aspect, the movable body has an extension portion in which the optical module extends from the opening portion to the outside of the fixed body, and a buffer is provided at a position facing the constituent members of the optical device in the optical axis direction at the extension portion. Therefore, with this buffer, when the optical device is dropped or the like, the impact between the optical module and the constituent members of the optical device can be reduced, and the occurrence of a failure can be reduced. Further, if the buffer is provided between the movable body and the fixed body, the movable area of the movable body relative to the fixed body must be ensured and the arrangement space of the buffer is ensured, whereby the optical unit is easy to be enlarged.
In the optical unit of the present invention, the optical unit may be configured to: the buffer is provided in the protruding portion in a size and arrangement that does not come into contact with the constituent member when the movable body is rotated relative to the fixed body with the rotation axis as a reference. With this configuration, when the movable body rotates with respect to the fixed body about the rotation axis, the damper can be prevented from interfering with the rotation movement of the movable body with respect to the fixed body.
In the optical unit according to the present invention, the buffer may be made of a non-dusting material that does not generate dust when in contact with the component. By adopting such a structure, dust generated when the buffer member contacts with the constituent members can be suppressed from contaminating the inside of the optical apparatus.
In the optical unit of the present invention, the buffer may be made of a black material. By adopting such a configuration, the reflected light from the buffer can be suppressed, and the reflected light from the buffer can be suppressed from entering the optical module.
In the optical unit of the present invention, the buffer may be made of a non-glossy material having no gloss. By adopting such a configuration, the reflected light from the buffer can be suppressed, and the reflected light from the buffer can be suppressed from entering the optical module.
In the optical unit of the present invention, the optical unit may be configured to: the buffer is disposed at a position offset from an optical path of the optical module. By adopting such a configuration, it is possible to suppress a situation in which an incident light beam incident from the outside of the optical device is blocked by the buffer and cannot enter the optical module.
In the optical device of the present invention, the optical device may be configured to: the optical unit is provided such that a distance between the constituent member and the buffer member in the optical axis direction is smaller than a distance between the movable body and the fixed body in the optical axis direction. By adopting such a configuration, contact between the movable body and the solid can be suppressed when the optical device is dropped or the like, and thus, the optical device is less likely to be defective.
Effects of the invention
The optical unit of the present invention is not likely to cause a problem even when an optical device is dropped, and can be miniaturized.

< Overview of device with optical Unit >
First, an optical unit 1 according to embodiment 1 of the present invention will be described. Fig. 1 is a schematic perspective view of a smartphone 100 as an example of a device (optical device) including an optical unit 1 of the present embodiment. The optical unit 1 of the present embodiment can be desirably used in the smartphone 100. This is because the optical unit 1 of the present embodiment can be configured to be thin, and the thickness of the smartphone 100 in the Y-axis direction can be configured to be thin. However, the optical unit 1 of the present embodiment is not limited to the use in the smart phone 100, and may be used in various devices such as a camera and a video camera, and is not particularly limited.
As shown in fig. 1, a smartphone 100 includes a glass cover 101 into which a light beam is incident. The optical unit 1 is provided inside the glass cover 101 of the smart phone 100. The smartphone 100 is configured to be able to take an object image based on an incident light beam, which is incident in the incident direction D1 from the outside via the glass cover 101.
< Overview of the overall Structure of optical Unit >
An outline of the configuration of the optical unit 1 of the present embodiment will be described with reference to fig. 2 to 5. The optical unit 1 includes: a movable body 14 including an optical module 12 such as a lens 12a and an imaging element 50; and a fixed body 16 that is held in a state that it can be displaced in a direction (pitch direction) with the X-axis direction as a rotation axis (yaw axis) and in a direction (yaw direction) with the Z-axis direction as a rotation axis (yaw axis). The present invention further includes: a driving mechanism 18 (driving mechanism 18A and driving mechanism 18B) that drives the movable body 14 in the pitch direction and the yaw direction; and a support mechanism 20 that supports the movable body 14 so as to be rotatable (swingable) in the pitch direction and the yaw direction with respect to the fixed body 16.
< Concerning the movable body >
As shown in fig. 4 and 5, the optical unit 1 of the present embodiment includes a movable body main body 14A and a holder 14B as the movable body 14. The movable body main body 14A includes the optical module 12, the image pickup device 50, a flexible printed board 51 connected to the image pickup device 50, and the like. The holder 14B holds the movable body main body 14A, and is provided with a magnet 24A and a magnet 24B constituting the driving mechanism 18.
Thus, the movable body 14 includes: a movable body main body 14A provided with an optical module 12 and the like; and a holder 14B provided with magnets 24A and 24B, etc. The holder 14B is configured as a rectangular frame-like member provided so as to surround the remaining four surfaces of the optical module 12 except for the front surface (surface on the object side) where the lens 12a is provided and the rear surface on the opposite side. As an example, the holder 14B of the present embodiment is configured to be detachable from the optical module 12. However, the optical module 12 and the holder 14B may be integrally formed. The magnets 24A and 24B for correcting pitch and yaw are attached to the outer surfaces of the holder 14B by the two surfaces facing the fixed body 16.
In addition, as shown in fig. 2 to 5, the optical unit 1 of the present embodiment has a fixing body 16. In fig. 2 to 5, the fixed body 16 has an upper surface cover 16a, and includes a coil 32A at a position overlapping the upper surface cover 16a and facing the magnet 24A when viewed in the Y-axis direction, and includes a coil 32B at a position overlapping the upper surface cover 16a and facing the magnet 24B when viewed in the Y-axis direction. In the present embodiment, the coils 32A and 32B are configured as winding coils as an example, but may be pattern substrates (coil substrates) in which coils are incorporated as patterns in substrate wiring. Further, an opening 16b is formed in the upper surface cover 16a so that the holding portion 12b of the lens 12a of the optical module 12 protrudes outward (-Y direction side).
< Optical Module >
The optical module 12 of the present embodiment can be used for a mobile phone with a camera, a tablet PC, or the like other than the smart phone 100, for example. The optical module 12 includes a lens 12a on the object side, and an optical device or the like for performing imaging is built in a lower portion (+inner region on the Y direction side) of a holding portion 12b of the lens 12 a. As shown in fig. 2 to 5, a buffer 12c is provided on the object side (-Y direction side) of the holding portion 12b so as to surround the lens 12a when viewed in the Y axis direction. The details of the cushioning member 12c will be described later.
Here, the optical unit 1 of the present embodiment has a drive mechanism 18 incorporated therein as an example, and the drive mechanism 18 corrects pitch shake (shake in a rotational direction about an X-axis direction as a rotational axis) and yaw shake (shake in a rotational direction about a Z-axis direction as a rotational axis) generated by the optical module 12, and the optical unit 1 is configured to be capable of correcting pitch shake and yaw shake. In the present embodiment, the optical module 12 is configured to be able to correct pitch shake and yaw shake, but may be configured to be able to further correct shake in the rolling direction (shake in the rotational direction about the Y-axis direction as the rotation axis). The image pickup device 50 may be regarded as a part of the optical module 12.
< Concerning the drive mechanism >
In the present embodiment, in a state in which the movable body 14 is disposed in the fixed body 16, the magnet 24A and the coil 32A, and the magnet 24B and the coil 32B are in a facing state, respectively. In the present embodiment, the pair of the magnet 24A and the coil 32A, and the pair of the magnet 24B and the coil 32B constitute the driving mechanism 18. The drive mechanism 18 corrects the pitch and yaw of the movable body 14.
In addition, correction of pitch and yaw is performed as follows. When the optical unit 1 is subject to shake in both or either of the pitch direction and the yaw direction, the shake is detected by a magnetic sensor (hall element 33: see fig. 4 and 5), and the driving mechanism 18 is driven based on the result. Alternatively, a shake detection sensor (gyroscope) or the like may be used to detect shake of the optical unit 1. Based on the detection result of the shake, the driving mechanism 18 functions to correct the shake. That is, a current is applied to each of the coils 32A and 32B to move the movable body 14 in a direction to cancel the shake of the optical unit 1, thereby correcting the shake.
As described above, the optical unit 1 of the present embodiment includes the driving mechanism 18, and the driving mechanism 18 rotates the movable body 14 with respect to the fixed body 16 about the pitch axis and the yaw axis as rotation axes. Here, the driving mechanism 18 is preferably disposed at a position other than the side (the +z direction side) of the movable body 14 where the flexible printed board 51 is disposed in the X axis direction. Since the driving mechanism 18 can be disposed on the side where the flexible printed board 51 is not formed, it is not necessary to enlarge the optical unit 1 in order to suppress contact between the driving mechanism 18 and the flexible printed board 51, and the optical unit 1 can be miniaturized. In addition, "rotation" in this specification includes a case of swinging in a rotation direction without rotating 360 °.
< About the supporting mechanism >
The support mechanism 20 of the present embodiment is a gimbal mechanism having both elasticity and formed by bending a metal flat plate material. Specifically, as shown in fig. 4 and 5, the support mechanism 20 includes, as an example, a gimbal frame portion 23 provided on the object side, a first support portion extending portion 21 formed by bending 90 ° in the optical axis direction from four corner portions of the gimbal frame portion 23, and a second support portion extending portion 22. The first support portion extending portion 21 and the second support portion extending portion 22 are not necessarily all plate-shaped, and may be formed only partially plate-shaped to exhibit elasticity. In addition, one of the first support portion extending portion 21 and the second support portion extending portion 22 may be formed in a shape other than a plate shape (for example, a rod shape). The support mechanism 20 of the present embodiment is configured to support the movable body 14 rotatably with respect to the fixed body 16 in a direction in which both the pitch direction and the yaw direction are rotation axes, but may be configured to support the movable body 14 rotatably with respect to the fixed body 16 in a direction in which only one of the pitch direction and the yaw direction is rotation axis.
The support mechanism 20 of the present embodiment has a concave curved surface 21a recessed toward the inside at the first support portion extending portion 21, and a concave curved surface 22a recessed toward the inside at the second support portion extending portion 22. The first support portion extending portion 21 is applied with force so that the concave curved surface 21a expands outward, and the second support portion extending portion 22 is applied with force so that the concave curved surface 22a expands outward.
As shown in fig. 5, a stationary body side support 41 is provided at a position of the stationary body 16 facing the concave curved surface 21a, and the stationary body side support 41 is attached with a spherical convex curved surface 41a protruding inward and fitted into the concave curved surface 21 a. As shown in fig. 4, a movable body side support portion 42 is provided at a position of the holder 14B facing the concave curved surface 22a, and the movable body side support portion 42 is attached with a spherical convex curved surface 42a protruding inward and fitted into the concave curved surface 22 a. The optical unit 1 of the present embodiment supports the support mechanism 20 rotatably with respect to the fixed body 16 about the first axis L1 (see fig. 2) as a rotation axis by disposing the convex curved surface 41a in the concave curved surface 21a and pressing the concave curved surface 21a against the convex curved surface 41a. In the optical unit 1 of the present embodiment, the convex curved surface 42a is disposed in the concave curved surface 22a, and the concave curved surface 22a is pressed against the convex curved surface 42a, so that the movable body 14 is supported rotatably with respect to the support mechanism 20 about the second axis L2 (see fig. 2) as a rotation axis. That is, the support mechanism 20 of the present embodiment is configured as: the support mechanism 20 is supported so as to be rotatable about the first axis L1 as a rotation axis with respect to the fixed body 16, and the movable body 14 is supported so as to be rotatable about the second axis L2 as a rotation axis with respect to the support mechanism 20, whereby the movable body 14 is supported so as to be rotatable with respect to the fixed body 16 about all of directions intersecting the optical axis direction (Y-axis direction) as rotation axes. The optical unit 1 of the present embodiment is configured to: by driving the driving mechanism 18, the movable body 14 can be rotated with respect to the fixed body 16 with the pitch direction and the yaw direction as rotation axes.
< Cushioning Member >
Next, the cushioning material 12c will be described in detail with reference to fig. 6 in addition to fig. 2 to 5. As shown in fig. 2 to 5, the optical unit 1 of the present embodiment is formed with a buffer 12c annularly so as to surround the lens 12a when viewed from the Y-axis direction at the-Y-direction side end of the holding portion 12b of the optical module 12. The shape of the cushioning member 12c is not limited to a ring shape. The shape of the buffer 12c may not be circular, and the optical unit 1 may have a plurality of buffers 12c.
As described above, the optical unit 1 according to the present embodiment is an optical unit to be housed in an optical device such as a smartphone 100, and includes: a movable body 14 provided with an optical module 12; and a fixed body 16 that supports the movable body 14 so as to be rotatable about a direction intersecting the optical axis direction (incidence direction D1) of the optical module 12. As shown in fig. 3, the fixed body 16 has an opening 16b that opens in the optical axis direction, and the optical module 12 of the movable body 14 extends outside the fixed body 16 from the opening 16 b. Here, the holding portion 12b constitutes an extension portion extending from the opening portion 16b to the outside of the fixed body 16. As shown in fig. 6, a buffer 12c is provided at a position facing the glass cover 101, which is a component of the optical device, in the optical axis direction at the holding portion 12b, which is an extension portion.
As described above, in the optical unit 1 of the present embodiment, the movable body 14 has the holding portion 12b as the protruding portion of the optical module 12 protruding from the opening portion 16b to the outside of the fixed body 16, and the buffer 12c is provided at the position of the holding portion 12b facing the glass cover 101 as the constituent member of the optical device in the optical axis direction. Therefore, in the optical unit 1 of the present embodiment, by using the buffer 12c, the impact between the optical module 12 and the glass cover 101 can be reduced when the optical device is dropped or the like, and the occurrence of defects can be reduced.
Here, as a structure capable of reducing the impact between the optical module 12 and the glass cover 101 when the optical device is dropped or the like, for example, a structure in which the buffer 12c is provided between the movable body 14 and the fixed body 16 at the position of the gap G1 in fig. 6 may be considered. However, if the buffer 12c is provided between the movable body 14 and the fixed body 16, the movable area of the movable body 14 with respect to the fixed body 16 must be ensured and the arrangement space of the buffer 12c must be ensured, whereby the optical unit 1 is easily enlarged. Therefore, as in the present embodiment, by adopting a configuration in which the buffer 12c is provided at a position facing the glass cover 101, an increase in size of the optical unit 1 can be suppressed.
In the optical unit 1 of the present embodiment, as shown in fig. 6, the upper surface cover 16a is disposed so as to face the magnet 24A, and for example, the movable body 14 is rotated with respect to the fixed body 16 about the rotation axis C along the X-axis direction. The gap G1 between the upper surface cover 16a and the magnet 24A is formed to a length that is not in contact with the movable body 14 when the movable body is rotated relative to the fixed body 16 about the rotation axis C. Similarly, the gap between the upper surface cover 16a and the magnet 24B is also configured to have a length that is not in contact with the movable body 14 when the movable body is rotated relative to the fixed body 16 about the rotation axis along the Z-axis direction. In this way, in the optical unit 1 of the present embodiment, the following length is constituted: even when the movable body 14 is maximally rotated with respect to the fixed body 16, the movable body 14 is not in contact with the fixed body 16.
In the optical unit 1 of the present embodiment, the buffer 12c is provided in the holding portion 12b in a size and arrangement that does not come into contact with the glass cover 101 when the movable body 14 is rotated with respect to the fixed body 16 about the rotation axis. Specifically, in the optical unit 1 of the present embodiment, as shown in fig. 6, the gap G2 between the buffer 12c and the glass cover 101 is configured to have the following length: even when the movable body 14 is rotated and moved to the maximum extent with respect to the fixed body 16 with respect to any one of the rotation axis C and the rotation axis along the Z-axis direction, the damper 12C is not in contact with the glass cover 101. With this structure, when the movable body 14 is rotated with respect to the fixed body 16 about the rotation axis, the damper 12c can be prevented from interfering with the rotation movement of the movable body 14 with respect to the fixed body 16.
In the smartphone 100 as the optical device of the present embodiment, the gap G2 is smaller than the gap G1. In other words, in the smartphone 100 of the present embodiment including the optical unit 1 described above, the gap G2, which is the interval between the glass cover 101 and the buffer 12c in the optical axis direction, is smaller than the gap G1, which is the interval between the movable body 14 and the fixed body 16 in the optical axis direction. When the smartphone 100 is lowered, the movable body 14 is easily moved in the optical axis direction with respect to the fixed body 16, but by adopting such a configuration, the smartphone 100 of the present embodiment can suppress the contact between the movable body 14 and the fixed body 16 when the smartphone 100 is lowered, and the smartphone 100 is less likely to cause a problem.
In addition, in the optical unit 1 of the present embodiment, the buffer 12c is made of a non-dusting material that does not generate dust when in contact with the glass cover 101. By adopting such a structure, dust generated when the buffer 12c contacts the glass cover 101 can be prevented from contaminating the inside of the optical device. Specific examples of the non-dusting material include rubbers and porous materials.
In addition, in the optical unit 1 of the present embodiment, the buffer 12c is composed of a black material. By adopting such a configuration, the reflected light from the buffer 12c can be suppressed, and the reflected light from the buffer 12c can be suppressed from entering the optical module 12.
Further, in the optical unit 1 of the present embodiment, the buffer 12c is composed of a non-glossy material having no gloss. By adopting such a configuration, the reflected light from the buffer 12c can be suppressed, and the reflected light from the buffer can be suppressed from entering the optical module 12.
In the optical unit 1 of the present embodiment, the buffer 12c is configured to be disposed at a position offset from the optical path of the optical module 12 so as not to interfere with the optical path of the optical module 12. By adopting such a configuration, it is possible to suppress that an incident light beam incident from the outside of an optical device such as the smartphone 100 is blocked by the buffer 12c and cannot enter the optical module 12.
The present invention is not limited to the above-described embodiments, and can be implemented in various configurations within a range not departing from the gist thereof. For example, in order to solve some or all of the above-described technical problems, or in order to achieve some or all of the above-described effects, technical features in the embodiments corresponding to the technical features in the respective aspects described in the summary of the invention section may be replaced or combined as appropriate.
