Description

Technical Field

[0001] This application relates to the technical field of optical image stabilization, and particularly to an anti-shake actuating motor and a lens module. Background Art

[0002] With the development of camera technology, how to achieve the maximum degree of thinness and lightness while realizing the optical image stabilization function of the lens module has become the focus of research and development in the industry. For this reason, lens modules using SMA wires as optical image stabilization actuating mechanisms have gradually become popular in the industry. However, in most of such designs, the lens is arranged on a moving plate, and multiple SMA wires are arranged along the X-axis direction and / or the Y-axis direction on the moving plate. By energizing a certain SMA wire respectively, it contracts to pull the lens to move in the X-axis or Y-axis direction, or by energizing multiple SMA wires simultaneously, they contract to pull the lens to move in the direction of the angle between the X-axis and the Y-axis; in such designs, the movements in the X-axis direction and the Y-axis direction are coupled. When multiple SMA wires are energized and contracted simultaneously to pull the lens to move in the direction of the angle between the X-axis and the Y-axis, there are problems such as inaccurate movement, which directly affects the anti-shake accuracy of the lens and further leads to poor imaging quality. Summary of the Invention

[0003] This application aims to solve one of the technical problems existing in the prior art. For this reason, this application proposes an anti-shake actuating motor. The anti-shake actuating motor of this application has no coupling in movements in different directions, has accurate movement, good anti-shake effect and is thin and light in structure. This application also proposes a lens module.

[0004] The anti-shake actuating motor according to the first aspect embodiment of this application includes:

[0005] A fixing plate;

[0006] A first moving component, the first moving component is in a frame shape and is arranged on the surface of the fixing plate;

[0007] A first elastic arm, the first elastic arm connects the first moving component and the fixing plate, and the first elastic arm can be deformed to allow the first moving component to move relative to the fixing plate in a first direction;

[0008] A first SMA wire, connecting the fixing plate and the first moving component, for driving the first moving component to move relative to the fixing plate in the first direction;

[0009] A second moving component, the second moving component is arranged on the surface of the fixing plate and is located inside the frame of the first moving component;

[0010] The second elastic arm, the second elastic arm connects the second motion component and the first motion component, and the second elastic arm can be deformed to allow the second motion component to move relative to the first motion component along a second direction; wherein, the first direction and the second direction form a certain angle;

[0011] The second SMA wire, which connects the first motion component and the second motion component, is used to drive the second motion component to move relative to the first motion component along the second direction.

[0012] The anti-shake actuating motor according to the embodiment of the present application has at least the following beneficial effects:

[0013] When the second motion component needs to move along the second direction, the second SMA wire is energized to contract and pull the second motion component to move relative to the first motion component. At this time, the second elastic arm undergoes elastic deformation. When the second SMA wire is de-energized and relaxed, the second elastic arm resumes its original shape and drives the second motion component to reset;

[0014] When the second motion component needs to move along the first direction, the first SMA wire is energized to contract and pull the first motion component to move. Since the second elastic arm only allows elastic deformation in the second direction, when the first motion component moves in the first direction, the first motion component drives the second motion component to move in the first direction; when the first SMA wire is de-energized and relaxed, the first elastic arm resumes its original shape and drives the first motion component to reset;

[0015] When the second motion component needs to move in the direction of the angle between the first direction and the second direction, the first SMA wire is energized to contract and pull the first motion component to drive the second motion component to move relative to the fixed plate in the first direction. At the same time, the second SMA wire is energized to contract and pull the second motion component to move relative to the first motion component in the second direction, so as to realize the movement of the second motion component in the direction of the angle between the first direction and the second direction.

[0016] By setting it like this, when the second motion component moves in the first direction or the second direction, the first SMA wire and the second SMA wire act independently and do not interfere with each other, realizing the decoupling of the movement of the second motion component, which is beneficial to improving the accuracy of the movement of the anti-shake actuating motor and the accuracy of optical anti-shake, thereby improving the imaging quality of the lens module installed on the anti-shake actuating motor; in addition, the second motion component is arranged inside the frame of the first motion component, making the thickness of the anti-shake actuating motor smaller, which is beneficial to the thinning of the structure.

Moreover, the length direction of the first elastic arm is parallel to the second direction, and the length direction of the second elastic arm is parallel to the first direction; there is a certain gap between the first elastic arm and the first moving component, and there is a certain gap between the second elastic arm and the first moving component and the second moving component.

[0058] The following is based onFigures 1 to 11 Describe the anti-shake actuating motor according to the first aspect of the present application.

[0059] Reference Figure 1 , the anti-shake actuating motor of the present application includes:

[0060] Fixing plate 100;

[0061] The first moving component 200, the first moving component 200 is in a frame shape and is arranged on the surface of the fixing plate 100;

[0062] The first elastic arm 510, the first elastic arm 510 connects the first moving component 200 and the fixing plate 100, and the first elastic arm 510 can be deformed to allow the first moving component 200 to move relative to the fixing plate 100 in the first direction;

[0063] The first SMA wire 410, connecting the fixing plate 100 and the first moving component 200, is used to drive the first moving component 200 to move relative to the fixing plate 100 in the first direction;

[0064] The second moving component 300, the second moving component 300 is arranged on the surface of the fixing plate 100 and is located inside the frame of the first moving component 200;

[0065] The second elastic arm 520, the second elastic arm 520 connects the second moving component 300 and the first moving component 200, and the second elastic arm 520 can be deformed to allow the second moving component 300 to move relative to the first moving component 200 in the second direction; wherein, the first direction and the second direction form a certain angle;

[0066] The second SMA wire 420, connecting the first moving component 200 and the second moving component 300, is used to drive the second moving component 300 to move relative to the first moving component 200 in the second direction.

[0067] It should be understood that the first direction can be understood as the X-axis direction, and the second direction can be understood as the Y-axis direction.

[0068] It can be understood that when the second moving component 300 needs to move in the Y-axis direction, the second SMA wire 420 is energized to contract and pull the second moving component 300 to move relative to the first moving component 200. At this time, the second elastic arm 520 undergoes elastic deformation. When the second SMA wire is de-energized and relaxed, the second elastic arm 520 returns to its original state and drives the second moving component to reset;

[0069] When the second moving component 300 needs to move in the X-axis direction, the first SMA wire 410 is energized to contract and pull the first moving component 200 to move. Since the second elastic arm 520 only allows elastic deformation in the Y-axis direction, when the first moving component 200 moves in the X-axis direction, the first moving component 200 drives the second moving component 300 to move in the X-axis direction; when the first SMA wire is de-energized and relaxed, the first elastic arm 510 returns to its original state and drives the first moving component 200 to reset;

[0070] When the second moving component 300 needs to move in the direction of the angle between the X-axis direction and the Y-axis direction, the first SMA wire 410 is energized to contract and pull the first moving component 200 to drive the second moving component 300 to move relative to the fixed plate 100 in the X-axis direction. At the same time, the second SMA wire 420 is energized to contract and pull the second moving component 300 to move in the Y-axis direction relative to the first moving component 200, so as to realize the movement of the second moving component 300 in the direction of the angle between the X-axis direction and the Y-axis direction.

[0071] By such setting, when the second moving component 300 moves in the X-axis direction or the Y-axis direction, the first SMA wire 410 and the second SMA wire 420 act independently and do not interfere with each other, realizing the decoupling of the movement of the second moving component 300, which is beneficial to improving the accuracy of the movement of the anti-shake actuator motor, improving the accuracy of optical anti-shake, and thus improving the imaging quality of the lens module installed on the anti-shake actuator motor; in addition, the second moving component 300 is arranged inside the frame of the first moving component 200, making the thickness of the anti-shake actuator motor smaller, which is beneficial to the thinning of the structure.

[0072] Reference Figures 1 to 3 In some embodiments of the present application, two first SMA wires 410 and two second SMA wires 420 are provided; both the first SMA wire 410 and the second SMA wire 420 are bent in a V shape; connecting members 600 are provided at the connection between the first moving component 200 and the first SMA wire 410 and at the connection between the second moving component 300 and the second SMA wire 420, and the V-shaped vertices of the first SMA wire 410 and / or the second SMA wire 420 are hooked on the connecting members 600.

[0073] It can be understood that both the first SMA wire 410 and the second SMA wire 420 are V-shaped bent. Taking the first SMA wire 410 as an example. When the first SMA wire 410 is energized and contracts to pull the first moving component 200 to move, the V-shaped angle on the first SMA wire 410 becomes larger. The distance between the V-shaped vertices of the first SMA wire 410 before and after being energized is the translation distance of the first moving component 200 relative to the fixed plate 100. The distance between the V-shaped angle vertices of the first SMA wire 410 before and after being energized is much larger than the contraction length of the first SMA wire 410. Moreover, when the V-shaped angle on the first SMA wire 410 is larger, when the first SMA wire 410 contracts by the same amount, the distance that the V-shaped vertex moves is larger, thus playing a role in amplifying the stroke. Therefore, the length of the first SMA wire 410 can be reduced when the movement stroke is certain, thereby reducing the volume of the anti-shake actuator motor, which is beneficial to the miniaturization of the device.

[0074] It can be understood that regarding the connecting member 600. The V-shaped vertices of the first SMA wire 410 and / or the second SMA wire 420 are hooked on the connecting member 600. And the connecting member 600 is respectively arranged on the symmetry axes of the first moving component 200 and the second moving component 300, so that the first moving component 200 can slide freely relative to the first SMA wire 410, and the second moving component 300 can slide freely relative to the second SMA wire 420. Taking the first moving component 200 as an example again, when the first SMA wire 410 is energized and contracts and tensions to pull the first moving component 200 to move, the first SMA wire 410 can be automatically corrected in the tensioned state to prevent the situation that the first SMA wire 410 is asymmetric relative to the first moving component 200, which is beneficial to making the movement of the first moving component 200 more stable.

[0075] It can be understood that regarding the connecting member 600. The connecting member 600 can be integrally formed with the first moving component 200 or the second moving component 300, or can be independently arranged and installed on the first moving component 200 or the second moving component 300. When the connecting member 600 is integrally formed with the first moving component 200 or the second moving component 300, for example Figure 5 as shown, the connecting member 600 is formed by bending the first moving component 200 or the second moving component 300, and an arc-shaped groove is formed at the bending position. The V-shaped vertices of the first SMA wire 410 and / or the second SMA wire 420 are hooked in the arc-shaped groove. When the connecting member 600 is independently arranged, the connecting member 600 can adopt a connecting block made of insulating material. For example Figure 4 as described, the SMA wire is hooked on the connecting block. It should be noted that the surface of the connecting block in contact with the SMA wire is an arc surface to reduce the wear of the SMA wire; in addition, the connecting block can also adopt a design form of opening an arc-shaped groove on the contact surface with the SMA wire, so that the SMA wire is threaded through the arc-shaped groove. Such a setting can prevent the SMA wire from detaching from the connecting member 600 and make the connection between the SMA wire and the connecting member 600 more stable.

[0076] It can be understood that there are two first SMA lines 410 and two second SMA lines 420 respectively. Specifically, the V-shaped vertices on the two first SMA lines 410 are respectively connected to the symmetric two sides of the first moving component 200, so that the first SMA lines 410 can pull the first moving component 200 to move in the opposite directions of the X-axis; the V-shaped vertices on the two second SMA lines 420 are respectively connected to the symmetric two sides of the second moving component 300, so that the second SMA lines 420 can pull the second moving component 300 to move in the opposite directions of the Y-axis.

[0077] In some embodiments of the present application, a sliding member is further provided, and the sliding member is disposed between the fixed plate 100 and the first moving component 200 and / or between the fixed plate 100 and the second moving component 300.

[0078] It can be understood that setting the sliding member can reduce the friction between the first moving component 200 and the fixed plate 100, and between the second moving component 300 and the fixed plate 100. Specifically, the sliding member can be a wear-resistant plastic block or other components such as a plain bearing, and is not limited thereto. At least three sliding members are respectively provided between the fixed plate 100 and the first moving component 200, and between the fixed plate 100 and the second moving component 300, so as to achieve the effect of stable support.

[0079] It should be understood that the first elastic arm 510 is bent and deformed on the Z-axis so that one end thereof abuts against the fixed plate 100, so that the first moving component 200 is pressed against the sliding member to reduce the clearance between the first moving component 200 and the fixed plate 100, and the second elastic arm 520 presses the second moving component 300 against the sliding member to reduce the clearance between the second moving component 300 and the fixed plate 100, thereby making the anti-shake movement more accurate.

[0080] Reference Figures 3 to 5 In some embodiments of the present application, a support member 700 is further provided. The support member 700 is fixedly disposed between the fixed plate 100 and the first elastic arm 510. One end of the first elastic arm 510 is connected to the first moving component 200, and the other end is connected to the support member 700.

[0081] It can be understood that in some cases, the sliding member can be unset. Instead, a support member 700 is provided at the connection between the first elastic arm 510 and the fixed plate 100. Specifically, the support member 700 is disposed between the fixed plate 100 and the first elastic arm 510. One end of the first elastic arm 510 is attached to the upper surface of the support member 700, and the other end is connected to the first motion component 200. Thus, the first elastic arm 510 suspends and supports the first motion component 200, leaving a certain gap between the first motion component 200 and the fixed plate 100. The height of the gap is the height of the support member 700. The second elastic arm 520 suspends and supports the second motion component 300, so that the first motion component 200 and the second motion component 300 are located on the same height plane. By such an arrangement, the first motion component 200 or the second motion component 300 does not directly contact the fixed plate 100, which is beneficial to reducing sliding friction and improving the smoothness of the anti-shake motion. At the same time, the dust problem caused by sliding friction when installing the sliding member can also be eliminated.

[0082] Reference Figures 6 to 10 , in some embodiments of the present application, the lengths of both the first elastic arm 510 and the second elastic arm 520 are greater than the widths, and the length direction of the first elastic arm 510 is parallel to the second direction, and the length direction of the second elastic arm 520 is parallel to the first direction. There is a certain gap between the first elastic arm 510 and the first motion component 200, and there is a certain gap between the second elastic arm 520 and the first motion component 200 and the second motion component 300.

[0083] It should be understood that both the first motion component 200 and the second motion component 300 are rectangular, and the first motion component 200 is in a frame shape, and the second motion component 300 is disposed inside the frame of the first motion component 200. The first elastic arm 510 is disposed between the first motion component 200 near the first SMA wire 410 and the fixed plate 100, and the first elastic arm 510 is disposed outside the frame of the first motion component 200. The second elastic arm 520 is disposed between the second motion component 300 near the second SMA wire 420 and the first motion component 200, and the second elastic arm 520 is disposed in the gap between the first motion component 200 and the second motion component 300.

[0084] It should be understood that there is a certain gap between the first elastic arm 510 and the first motion component 200, so that the first motion component 200 will not interfere with the first elastic arm 510 during movement, thereby increasing the movement range of the first motion component 200. There is also a certain gap between the second elastic arm 520 and the first motion component 200 and the second motion component 300, which can also increase the movement range of the second motion component 300.

[0085] It can be understood that the length of the first elastic arm 510 and the second elastic arm 520 are both greater than the width, so that the deformation capacity of the first elastic arm 510 and the second elastic arm 520 in the width direction is much greater than the deformation capacity in the length direction. Specifically, the length direction of the first elastic arm 510 is parallel to the Y-axis direction, so that the first elastic arm 510 can be greatly deformed in the X-axis direction; the length direction of the second elastic arm 520 is parallel to the X-axis direction, so that the second elastic arm 520 can be greatly deformed in the Y-axis direction. Therefore, in the X-axis direction, the first motion component 200 and the second motion component 300 are equivalent to a whole, and during the process of the first motion component 200 resetting relative to the fixed plate 100, the second motion component 300 moves with the first motion component 200.

[0086] It is understandable that the shape of the first elastic arm 510 and the second elastic arm 520 can be wavy or straight, as long as the deformation capacity of the first elastic arm 510 and the second elastic arm 520 in the width direction is much greater than the deformation capacity in the length direction, and the shape is not limited to this.

[0087] Through such an arrangement, the first elastic arm 510 can only provide elastic force in the X-axis direction, and the second elastic arm 520 can only provide elastic force in the Y-axis direction; in addition, by reasonably arranging the positions of the first elastic arm 510 and the second elastic arm 520, the space and area occupied by the first motion component 200 and the second motion component 300 are minimized, which is conducive to the miniaturization of the anti-shake actuator motor.

[0088] refer to Figure 2 , Figure 3 , Figure 9 and Figure 10 In some embodiments of the present application, the first elastic arm 510 and the second elastic arm 520 are both straight arms.

[0089] It is understandable that the first elastic arm 510 and the second elastic arm 520 are both straight arms, so that the first elastic arm 510 and the second elastic arm 520 have no elastic force in their length direction. When the first motion component 200 drives the second motion component 300 to move in the X-axis direction, the second elastic arm 520 has no elastic force in the X-axis direction, which is conducive to strengthening the integrity of the first motion component 200 and the second motion component 300, so that the second motion component 300 can smoothly follow the movement of the first motion component 200, thereby facilitating the increase of the accuracy of the anti-shake movement.

[0090] refer to Figure 9 In some embodiments of the present application, the plane where the width of the first elastic arm 510 is located is perpendicular to the first direction, and the plane where the width of the second elastic arm 520 is located is perpendicular to the second direction.

[0091] It can be understood that when the support member 700 is provided, in order to make the stiffness of the first elastic arm 510 or the second elastic arm 520 in the Z-axis direction much greater than that in the X-axis or Y-axis direction, the following settings are made for the first elastic arm 510 and the second elastic arm 520: the thicknesses of the first elastic arm 510 and the second elastic arm 520 are both smaller than the widths. Specifically, taking the first elastic arm 510a as an example, the width of the first elastic arm 510a can be twice or more of the thickness, and the plane where the width of the first elastic arm 510a is located is perpendicular to the Y-axis direction. With such settings, the stiffness of the first elastic arm 510 in the X-axis direction is less than that in the Z-axis direction, and the stiffness of the second elastic arm 520 in the Y-axis direction is less than that in the Z-axis direction, so as to better suspend and support the first moving assembly 200 and the second moving assembly 300, further making the movement more accurate and beneficial to improving the anti-shake movement accuracy.

[0092] Reference Figure 10 , in some embodiments of the present application, the first moving assembly 200 is made of a conductive material and includes a first connecting plate 210, a second connecting plate 220 and a common plate 230 that are insulated from each other; one end of one second SMA wire 420 is connected to the first connecting plate 210 and the other end is connected to the common plate 230, and one end of the other second SMA wire 420 is connected to the second connecting plate 220 and the other end is connected to the common plate 230.

[0095] Regarding the power supply settings of the four connecting pieces on the first moving assembly 200, the following technical solutions can be adopted:

[0096] The first moving component 200 is a metal plate. Setting the first moving component 200 as a metal plate can endow the first moving component 200 with better rigidity and prevent the first moving component 200 from deforming. A flexible circuit board is laid on the first moving component 200, and multiple power supply terminals are arranged on the flexible circuit board to independently supply power to the four connecting pieces. At the same time, the four connecting pieces are insulated from the first moving component 200. Specifically, an insulating adhesive or other insulating means can be pasted between the connecting piece and the first moving component 200 to prevent problems such as short circuits between the connecting pieces.

[0097] It can be understood that in addition to the above technical solutions, the first moving component 200 can also be arranged in the following forms: The first moving component 200 includes a first connecting plate 210, a second connecting plate 220 and a common plate 230 that are insulated from each other. The first connecting plate 210, the second connecting plate 220 and the common plate 230 are all made of conductive materials. Insulating plates 240 are connected to the surfaces of the first connecting plate 210, the second connecting plate 220 and the common plate 230 facing the fixed plate 100. The first connecting piece 211 is arranged on the first connecting plate 210 and is integrally formed with the first connecting plate 210. The third connecting piece 221 is arranged on the second connecting plate 220 and is integrally formed with the second connecting plate 220. The second connecting piece 231 and the fourth connecting piece 232 are both arranged on the common plate 230 and are integrally formed with the common plate 230. When it is necessary to energize one of the second SMA wires 420, the first connecting plate 210 and the common plate 230 are energized. When it is necessary to energize the other second SMA wire 420, the second connecting plate 220 and the common plate 230 are energized. With such a setting, the circuit arrangement on the first moving component 200 is more concise and it is also convenient for circuit control.

[0098] Reference Figure 11 , in some embodiments of the present application, the fixed plate 100 is made of a conductive material and includes a plurality of conductive plates that are insulated from each other; both ends of the first SMA wire 410 are respectively connected to different conductive plates; the first connecting plate 210, the second connecting plate 220 and the common plate 230 are all electrically connected to different conductive plates through the first elastic arms 510.

[0099] It can be understood that the fixed plate 100 includes five conductive plates that are insulated from each other, namely a first conductive plate 110, a second conductive plate 120, a third conductive plate 130, a fourth conductive plate 140 and a fifth conductive plate 150. The five conductive plates are arranged side by side in one direction.

[0100] Specifically, a fifth connecting piece 111 and a seventh connecting piece 112 are provided on the first conductive plate 110, and the fifth connecting piece 111 and the seventh connecting piece 112 are located on the same side of the fixing plate 100; an eighth connecting piece 141 is provided on the fourth conductive plate 140, and a sixth connecting piece 151 is provided on the fifth conductive plate 150. The sixth connecting piece 151 and the eighth connecting piece 141 are located on the other side of the fixing plate 100. Two ends of one first SMA wire 410 are respectively connected to the fifth connecting piece 111 and the sixth connecting piece 151, and two ends of the other first SMA wire 410 are respectively connected to the seventh connecting piece 112 and the eighth connecting piece 141. When it is necessary to energize one of the first SMA wires 410, the first conductive plate 110 and the fifth conductive plate 150 are energized. When it is necessary to energize the other SMA wire, the first conductive plate 110 and the fourth conductive plate 140 are energized.

[0101] Further, to facilitate the power supply of the second moving component 300, a second conductive plate 120 and a third conductive plate 130 are added. The first connecting plate 210 and the second conductive plate 120 are electrically connected through a first elastic arm 510a, the second connecting plate 220 and the third conductive plate 130 are electrically connected through a first elastic arm 510b, and the common plate 230 and the first conductive plate 110 are electrically connected through a first elastic arm 510c. Specifically, regarding the first elastic arm 510: the length of the first elastic arm 510c on the common plate 230 is adapted to the length of the long side of the common plate 230, and the middle part of the first elastic arm 510c is fixedly connected to the first conductive plate 110; the first elastic arm 510a and the first elastic arm 510b are also provided on the same side of the L shape of the first connecting plate 210 and the second connecting plate 220. The first elastic arm 510a and the first elastic arm 510b are equal in length and symmetrically arranged. The first elastic arm 510a on the first connecting plate 210 is fixedly connected to the second conductive plate 120, and the first elastic arm 510b on the second connecting plate 220 is fixedly connected to the third conductive plate 130. It should be understood that when only the support member 700 is provided on the fixing plate 100, the support member 700 is made of a metal conductive material or a conductive material such as conductive glue to realize the electrical connection between each first elastic arm 510 and each conductive plate.

[0102] By setting like this, the circuit structure of the anti-shake actuating motor can be greatly simplified, the processing procedure of laying the flexible circuit board on the surfaces of the fixing plate 100 and the first moving component 200 can be omitted, and the production and manufacturing are facilitated.

[0103] According to the lens module of the second aspect embodiment of the present application, it includes the above anti-shake actuating motor.

[0104] It can be understood that by setting like this, the anti-shake performance of the lens module is more accurate, which is beneficial to improving the anti-shake performance and further improving the lens quality.

[0105] The embodiments of the present application have been described in detail above in conjunction with the accompanying drawings. However, the present application is not limited to the above embodiments, and various changes can be made without departing from the gist of the present application within the scope of knowledge possessed by those of ordinary skill in the art.
