JP7502596B2 - Camera actuator, camera module, and camera-mounted device - Google Patents

Description

The present invention relates to a camera actuator, a camera module, and a camera-mounted device.

Thin camera-equipped devices equipped with a camera module, such as smartphones and digital cameras, are known. The camera module includes a lens unit having one or more lenses, and an image sensor that captures the subject image formed by the lens unit.

A camera module has also been proposed that includes a bending optical system in which a prism, which is an optical path bending member provided in front of the lens section, bends light from a subject along a first optical axis in the direction of a second optical axis and guides the light to a rear lens section (for example, Patent Document 1).

The camera module disclosed in Patent Document 1 includes a shake correction device that corrects camera shake that occurs in the camera, and an autofocus device that performs autofocus. Such a camera module has a shake correction actuator and an autofocus actuator as camera actuators.

The shake correction actuator includes a first actuator and a second actuator that oscillate the prism around two different axes. Specifically, the first actuator oscillates the prism around an oscillating axis that is perpendicular to a plane that includes the first optical axis and the second optical axis. The second actuator oscillates the prism around an oscillating axis that coincides with the second optical axis.

When camera shake occurs, the shake correction actuator oscillates the prism under the control of the control unit to correct the shake. This corrects the camera shake.

JP 2015-92285 A

In the case of the camera module disclosed in Patent Document 1 as mentioned above, the entire holder that holds the prism is made from synthetic resin. This causes issues such as low strength of the holder and reduced durability of the camera module. One possible solution to this issue would be to increase the amount of synthetic resin used in the holder, but this would result in a larger holder and larger camera module.

The object of the present invention is to provide a camera actuator, a camera module, and a camera-mounted device that can achieve both improved durability and compact size.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. Note that the camera actuator, camera module, and camera-mounted device according to the embodiments described below are examples of the camera actuator, camera module, and camera-mounted device according to the present invention, and the present invention is not limited to the embodiments.

[Embodiment]
A camera module according to an embodiment of the present invention will be described with reference to Figures 1 to 12B. Below, an overview of the camera module 1 will be described, followed by a description of the structures of the light path bending module 2, lens module 80, and image sensor module 81 included in the camera module 1. The camera actuator, camera module, and camera-mounted device according to the present invention may include all of the configurations described below, or may not include some of the configurations.

[The camera module]
The camera module 1 is mounted, for example, on a smartphone M (see FIGS. 11A and 11B), a mobile phone, a digital camera, a notebook computer, a tablet terminal, a portable game console, and a thin camera-mounted device (such as an in-vehicle camera).

The following describes each part of the camera module 1 of this embodiment based on the state in which it is incorporated into the camera module 1. In addition, the Cartesian coordinate system (X, Y, Z) shown in each figure is used to explain the structure of the camera module 1 of this embodiment.

When an image is actually captured by the camera-mounted device, the camera module 1 is mounted so that, for example, the X direction is the left-right direction, the Y direction is the up-down direction, and the Z direction is the front-back direction. Light from a subject (incident light) enters the prism 5 of the light path bending module 2 from the + side (plus side) of the Z direction, as shown by the dashed dotted line α (also called the first optical axis) in Figure 1. The prism 5 is an example of a light path bending member.

The light (outgoing light) incident on the prism 5 is bent at the optical path bending surface of the prism 5 as shown by the dashed line β (also called the second optical axis) in FIG. 1, and is guided to the lens portion 801 of the lens module 80 arranged downstream of the prism 5 (i.e., on the + side of the X direction).

The subject image formed by the lens unit 801 is then captured by the image sensor module 81 (see FIG. 1) arranged behind the lens module 80.

In this embodiment, the direction from the positive Z side to the negative Z side corresponds to an example of the first direction. Also, the direction from the negative X side to the positive X side corresponds to an example of the second direction. However, the first direction and the second direction are not limited to the case of this embodiment. The first direction and the second direction may be any direction as long as they are perpendicular to each other.

The camera module 1 of this embodiment performs shake correction (OIS: Optical Image Stabilization) using the shake correction device 6 built into the light path bending module 2. In other words, the light path bending module 2 has a hand shake correction function.

In addition, the camera module 1 of this embodiment performs autofocus by displacing the lens unit in the X direction using an AF device (not shown) built into the lens module 80. In other words, the lens module 80 has an autofocus function.

The lens unit 801 of the lens module 80 is a so-called zoom lens that can handle both wide-angle photography (short focal length) and telephoto photography (long focal length). The camera module 1 of this embodiment uses a zoom device (not shown) built into the lens module 80 to move the lens unit 801 to a position in the X direction corresponding to wide-angle photography or telephoto photography. In other words, the lens module 80 has a zoom function.

<Shake correction device>
Next, the shake correction device 6 will be described. The shake correction device 6 is a drive unit that performs shake correction in a first rotation direction centered on the first axis A1 and shake correction in a second rotation direction centered on the second axis A2 by swinging the prism 5 about a first axis A1 (see FIGS. 2 and 8) parallel to the Z direction and a second axis A2 (see FIGS. 2, 9A, and 9B) parallel to the Y direction.

(First swing support part)
The first swing support portion 65 will be described with reference to Figures 2, 3, and 8. Figure 8 is a cross-sectional view of the first swing support portion 65.

The first swing support part 65 supports the support plate 64 in a swingable state about a first axis A1 (see Figs. 2 and 8) relative to the base 4. The first swing support part 65 is provided between the base part 641 of the support plate 64 and the bottom wall part 40 of the base 4 (the part surrounded by the dashed line X in Fig. 3). Specifically, the first swing support part 65 has a bearing 651, a first swing shaft 652, and a leaf spring 653.

As shown in FIG. 3, the leaf spring 653 has a fixing portion 654, a pressing portion 655, and a connecting portion 656.

The fixing portion 654 is provided at a first end of the leaf spring 653 and is fixed to the leaf spring fixing portion 403 (see Figures 5A and 5B) in the bottom wall portion 40 of the base 4.

In the assembled state, the pressing portion 655 of the leaf spring 653 presses the second end surface (upper end surface) of the first oscillating shaft 652 downward. Based on the downward biasing force received from the leaf spring 653, the first end surface (lower end surface) of the first oscillating shaft 652 is pressed against the upper surface of the base plate 44.

The first magnet 671a is arranged in the first magnet arrangement portion 623a in the first side wall portion 621a of the holder 61, which is the movable member. The first magnet 671a is fixed to the first surface (outer surface) of the first plate portion 632 of the insert plate 63 via the first yoke 675a by a fixing means such as adhesive.

The first magnet 671a consists of two magnet elements adjacent to each other in the X direction. Each of these magnet elements is magnetized in the Y direction and has one magnetic pole on one side. The magnetic poles of each magnet element are oriented in the opposite directions.

The first coil 672a is an elliptical, so-called air-core coil to which power is supplied during shake correction. The first coil 672a is fixed to the second coil holding portion 434a (see FIG. 5B) of the first side plate portion 431a of the coil holder 43 by a fixing means such as adhesive, with the major axis aligned with the Z direction.

The first coil 672a faces the first magnet 671a with a predetermined gap therebetween in the Y direction.

The right drive unit 67b includes a first magnet 671b and a first coil 672b.

The first magnet 671b is arranged in the second magnet arrangement portion 626b in the second side wall portion 624b of the holder 61, which is the movable member. The first magnet 671b is fixed to the first surface (outer surface) of the second plate portion 633 of the insert plate 63 via the first yoke 675b by a fixing means such as adhesive.

The control unit 92 determines the position of the first position detection magnet 673 (support plate 64 and holder 61) around the first axis A1 based on the detection value received from the first position detection element 674.

(Operation of First Driving Unit)
In the case of the first drive unit 67 having the above-mentioned configuration, when a current flows through the first coil 672a via the FPC 7 under the control of the control unit 92, a Lorentz force is generated that displaces the first magnet 671a to one side in the X direction. On the other hand, when a current flows through the first coil 672b via the FPC 7 under the control of the control unit 92, a Lorentz force is generated that displaces the first magnet 671a to the other side in the X direction.

Since the first magnets 671a and 671b are fixed to the holder 61, the holder 61 swings around the first axis A1 based on the Lorentz force. The direction of movement (rotation) of the holder 61 can be switched by controlling the direction of the current flowing through the first coils 672a and 672b.

(Note regarding the first drive unit)
In this embodiment, the first driving unit is provided between the base 4 (fixed member) and the holder 61 (inner movable member). However, the position of the first driving unit is not limited to this embodiment. For example, the first driving unit may be provided between the base 4 (fixed member) and the support plate 64 (outer movable member). In this configuration, the support plate 64 swings about the first axis A1 relative to the base 4 based on the first driving force of the first driving unit. As a result, the holder 61 swings about the first axis A1 relative to the base 4.

(Second driving unit)
The second drive unit 68 swings the holder 61 around a second axis A2 (see FIGS. 2, 9A, and 9B). The second axis A2 is an axis parallel to the Y direction. Specifically, the second axis A2 coincides with the central axis of the second swing support unit 66.

The second magnet 681 is arranged in the magnet arrangement section 620a in the rear wall section 620 of the holder 61, which is the movable member. The second magnet 681 is fixed to the first surface (back surface) of the rear plate section 631 of the insert plate 63 via the second yoke 685 by a fixing means such as adhesive.

The second magnet 681 consists of two magnet elements adjacent in the Z direction. Each of these magnet elements is magnetized in the X direction and has one magnetic pole on one side. The magnetic poles of each magnet element are oriented in the opposite directions.

The second coil 682 is an elliptical, so-called air-core coil to which power is supplied during shake correction. The second coil 682 is fixed to the first coil holding portion 433 of the coil holder 43 of the base 4 by a fixing means such as adhesive, with the major axis aligned with the Y direction. The second coil 682 is provided on the negative side of the X direction relative to the second magnet 681. The second coil 682 faces the second magnet 681 with a predetermined gap therebetween in the X direction.

The second position detection magnet 683 is fixed to the rear surface of the rear wall portion 620 of the holder 61 by a fixing means such as adhesive (see Figure 4).

The second position detection element 684 is fixed to the first surface (inner surface) of the base 430 of the coil holder 43 (see FIG. 3). The second position detection element 684 is provided on the negative side of the X direction relative to the second position detection magnet 683. The second position detection element 684 faces the second position detection magnet 683 in the X direction.

The second position detection element 684 is connected to the FPC 7. The second position detection element 684 detects the magnetic flux (also referred to as information related to the position) of the second position detection magnet 683 and sends the detection value to a control unit 92 mounted on the sensor board 91. The control unit 92 determines the position of the second position detection magnet 683 (i.e., the holder 61) around the second axis A2 based on the detection value received from the second position detection element 684.

(Operation of the second driving unit)
In the case of the second drive unit 68 having the above-mentioned configuration, when a current flows through the second coil 682 via the FPC 7 under the control of the control unit 92, a Lorentz force is generated that displaces the second magnet 681 in the Z direction. Since the second magnet 681 is fixed to the holder 61, the holder 61 swings about the second axis A2 based on the above-mentioned Lorentz force. Note that the movement direction (rotation direction) of the holder 61 can be switched by controlling the direction of the current flowing through the second coil 682.

[Lens module]
The lens module 80 is disposed on the + side in the X direction relative to the light path bending module 2. Light from a subject is incident on the prism 5 of the light path bending module 2 from the + side in the Z direction, as indicated by a dashed line α (also referred to as a first optical axis) in FIG.

The light incident on the prism 5 is bent at the optical path bending surface of the prism 5 as shown by the dashed line β (also called the second optical axis) in Figure 1, and is guided to the lens portion 801 of the lens module 80, which is arranged downstream of the prism 5 (i.e., on the + side of the X direction).

The lens module 80 includes a cover 800, a base (not shown), a lens unit 801, and an AF device (not shown). The cover 800 may be integrated with the cover 3 of the optical path bending module 2, or may be separate.

The lens unit 801 has a lens barrel 801a and one or more lenses 801b held by the lens barrel 801a. The lens unit 801 is supported by the base via the lens guide so as to be displaceable in the X direction.

The AF device is a driving unit that displaces the lens unit 801 in the X direction for the purpose of autofocus. The structure of the AF device is not particularly limited. For example, the AF device may include a motor (not shown) and a conversion mechanism that converts the rotational motion of the motor into linear motion in the X direction to move the lens unit 801 in the X direction.

[Image sensor module]
The imaging element module 81 is disposed on the positive side in the X direction relative to the lens unit 801. The imaging element module 81 includes an imaging element, such as a charge-coupled device (CCD) image sensor or a complementary metal oxide semiconductor (CMOS) image sensor. The imaging element of the imaging element module 81 captures an image of a subject formed by the lens unit 801 and outputs an electrical signal corresponding to the subject image. A sensor board 91 is electrically connected to the imaging element module 81, and power is supplied to the imaging element module 81 via the sensor board 91, and an electrical signal of the subject image captured by the imaging element module 81 is output. Such an imaging element module 81 may have a conventionally known structure.

(Actions and Effects of the Present Embodiment)
According to this embodiment having the above-described configuration, it is possible to achieve both improved durability and miniaturization of the camera module 1.

That is, in the case of this embodiment, the holder 61 that holds the prism 5 has a metal insert plate 63 embedded in a holder body 62 made of synthetic resin. Therefore, the strength of the holder 61 can be increased without needlessly increasing the amount of synthetic resin used in the holder body 62. As a result, the durability of the camera module 1 can be improved. In addition, since the strength of the holder 61 can be ensured without increasing the amount of synthetic resin used in the holder body 62, the holder 61 does not become larger. As a result, the camera module 1 can be made smaller.
