Description

Technical Field

[0001] The present application belongs to the field of camera technology, and specifically relates to a camera module and electronic equipment. Background Art

[0002] With the development of electronic devices, users usually use the camera module of the electronic devices to capture images. As user needs increase, users have higher and higher requirements for image quality.

[0003] For a periscope camera device, it is necessary to use a reflector group to refract the light so that the optical path that originally requires a long straight-line distance is folded into the limited space inside the periscope camera device, thereby achieving a telephoto function. When anti-shake is performed, the reflector group is rotated to adjust the reflection angle, compensate for the change in the optical path caused by the shake, and ensure clear imaging. In the related art, the reflector group relies on different driving mechanisms to drive it to rotate around different axes. When one of the driving mechanisms drives the reflector group to rotate around a first axis, the movement of the reflector group will affect other driving mechanisms, so that other driving mechanisms will also exert a driving effect on the reflector group, causing the reflector group to deflect in directions other than the first axis, and then the reflector group cannot accurately rotate along the corresponding compensation direction, resulting in a poor anti-shake effect. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide a camera module and an electronic device that can solve the problem of poor anti-shake effect of the camera module in the related art.

[0005] In a first aspect, an embodiment of the present application provides a camera module, comprising a reflector group, an adapter, and a housing, wherein the reflector group is connected to the adapter, and the reflector group and the adapter are rotationally matched around a first axis, and the adapter is connected to the housing, and the adapter and the housing are rotationally matched around a second axis; The process of the reflector group rotating relative to the adapter around the first axis is a first anti-shake process, and the process of the adapter driving the reflector group to rotate relative to the housing around the second axis is a second anti-shake process, and the first anti-shake process and the second anti-shake process are independent of each other; The first axis intersects with the second axis, one of the first axis and the second axis is parallel to the optical axis direction of the camera module, or the plane formed by the first axis and the second axis intersects with the optical axis direction of the camera module.

[0006] In a second aspect, an embodiment of the present application further provides an electronic device, comprising a device housing and the above-mentioned camera module, wherein the camera module is disposed in the device housing.

[0007] In the embodiment of the present application, an adapter is added between the mirror group and the housing. The adapter is connected to the housing, and the mirror group is rotationally engaged with the adapter around a first axis. Therefore, the mirror group can be driven to rotate around the first axis relative to the adapter and the housing, realizing the anti-shake process of the mirror group around the first axis, that is, the first anti-shake process. Moreover, the mirror group is connected to the adapter, and the adapter is rotationally engaged with the housing around a second axis. Therefore, the adapter can be driven to drive the mirror group to rotate around the second axis relative to the housing, or the mirror group can be driven to drive the adapter to rotate around the second axis relative to the housing, realizing the anti-shake process around the second axis, that is, the second anti-shake process. The first anti-shake process and the second anti-shake process are independent of each other, that is, the first anti-shake process and the second anti-shake process can be carried out separately or simultaneously. The first anti-shake process will not affect the second anti-shake process, and the second anti-shake process will not affect the first anti-shake process.

[0008] With such a setting, by using the adapter, the mirror group does not need to be directly and movably connected to the housing. Then, when the mirror group is driven to rotate around the first axis, it will not affect its rotation around the second axis. Similarly, when the mirror group is driven to rotate around the second axis, it will not affect its rotation around the first axis, realizing the structural decoupling of the camera module. The anti-shake process of the mirror group is easier to control, which is beneficial to improving the control accuracy. The mirror group can accurately rotate along the corresponding compensation direction, which is beneficial to improving the anti-shake effect. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

[0012] The terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such used data can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of the same type, and do not limit the number of objects. For example, the first object can be one or multiple. In addition, "and / or" in the description and claims means at least one of the connected objects, and the character " / ", generally represents an "or" relationship between the associated objects before and after.

[0013] Next, in conjunction with the accompanying drawings, the camera module and electronic device provided by the embodiments of the present application will be described in detail through specific embodiments and their application scenarios.

[0014] Please refer to Figures 1 - 26, the camera module disclosed in the embodiments of the present application is applied to an electronic device. The camera module includes a mirror group 200, an adapter 300, and a housing 100. Among them, the mirror group 200 is used to reflect the light entering the camera module. The adapter 300 serves as an intermediate adapter component connecting the mirror group 200 and the housing 100. The mirror group 200 is disposed in the housing 100 through the adapter 300, and the housing 100 is used to protect the mirror group 200 and the adapter 300.

[0015] Optionally, the mirror group 200 includes a mirror 220 and a mirror base 210. The mirror 220 is installed on the mirror base 210, and the mirror base 210 is disposed in the housing 100 through the adapter 300. The mirror base 210 is connected to the adapter 300; Refer to Figure 1 As shown, the camera module may further include a lens 900. The lens 900 is disposed in the housing 100. The lens 900 is opposite to the mirror 220, and the light passes through the lens 900 and can be reflected by the mirror 220.

[0016] Refer to Figure 5 As shown, the mirror group 200 is connected to the adapter 300, and the mirror group 200 and the adapter 300 are rotationally matched around a first axis Z. The adapter 300 and the housing 100 do not rotate relative to each other around the first axis Z. The mirror group 200 can rotate around the first axis Z relative to the adapter 300 and the housing 100. That is to say, the mirror group 200 and the adapter 300 have a connection relationship such that the adapter 300 can drive the mirror group 200 to move, but does not affect the rotation of the mirror group 200 around the first axis Z relative to the adapter 300. When the mirror group 200 or the adapter 300 rotates around an axis other than the first axis Z, the mirror group 200 and the adapter 300 rotate synchronously. The embodiments of the present application do not limit the structure of the rotational matching between the mirror group 200 and the adapter 300.

[0017] Optionally, the first axis Z may be parallel to the optical axis of the camera module, or there may be an included angle between the direction of the first axis Z and the optical axis direction of the camera module. The embodiments of the present application do not limit the first axis Z.

[0018] Refer to Figure 7As shown, the adapter 300 is connected to the housing 100, and the adapter 300 and the housing 100 are rotationally engaged about the second axis Y. The mirror group 200 and the adapter 300 do not rotate relative to each other about the second axis Y. The adapter 300 can drive the mirror group 200 to rotate relative to the housing 100 about the second axis Y. That is to say, the adapter 300 and the housing 100 have a connection relationship. The adapter 300 is restricted by the housing 100, but it does not affect the rotation of the adapter 300 relative to the housing 100 about the second axis Y. When the adapter 300 is subjected to a driving force in a rotation direction other than about the second axis Y, the adapter 300 is fixed relative to the housing 100. The embodiments of the present application do not limit the structure of the rotational engagement between the adapter 300 and the housing 100.

[0019] Optionally, the adapter 300 and the housing 100 can be relatively fixed in the direction about the first axis Z through a magnetic component with magnetic attraction cooperation. Of course, they can also be connected by other means, as long as it does not affect the rotation of the mirror group 200 relative to the adapter 300 about the first axis Z; the mirror group 200 and the adapter 300 can be relatively fixed in the direction about the second axis Y through a magnetic component with magnetic attraction cooperation. Of course, they can also be connected by other means, as long as it does not affect the rotation of the adapter 300 relative to the housing 100 about the second axis Y.

[0020] Refer to Figure 2 and Figure 3 As shown, the first axis Z intersects the second axis Y. One of the first axis Z and the second axis Y is parallel to the optical axis direction of the imaging module. It can be that the first axis Z is parallel to the optical axis direction of the imaging module, or the second axis Y is parallel to the optical axis direction of the imaging module; or, the plane formed by the first axis Z and the second axis Y intersects the optical axis direction of the imaging module. Optionally, the first axis Z is perpendicular to the second axis Y. Further optionally, the plane formed by the first axis Z and the second axis Y is perpendicular to the optical axis direction of the imaging module. Of course, the first axis Z and the second axis Y can also intersect but not be perpendicular. The first axis Z can intersect the optical axis of the imaging module but not be perpendicular, and the second axis Y can also intersect the optical axis of the imaging module but not be perpendicular.

[0021] In the embodiment of the present application, an adapter 300 is added between the mirror group 200 and the housing 100. The adapter 300 is connected to the housing 100, and the mirror group 200 and the adapter 300 are rotationally engaged about the first axis Z. Therefore, the mirror group 200 can be driven to rotate about the first axis Z relative to the adapter 300 and the housing 100, realizing the anti-shake process of the mirror group 200 about the first axis Z, that is, the first anti-shake process. Moreover, the mirror group 200 is connected to the adapter 300, and the adapter 300 and the housing 100 are rotationally engaged about the second axis Y. Therefore, the adapter 300 can be driven to drive the mirror group 200 to rotate about the second axis Y relative to the housing 100, or the mirror group 200 can be driven to drive the adapter 300 to rotate about the second axis Y relative to the housing 100, realizing the anti-shake process about the second axis Y, that is, the second anti-shake process.

[0022] The first anti-shake process and the second anti-shake process are independent of each other, that is, the first anti-shake process and the second anti-shake process can be carried out separately or simultaneously. The first anti-shake process does not affect the second anti-shake process, and the second anti-shake process does not affect the first anti-shake process.

[0023] With such a setting, by using the adapter 300, the mirror group 200 does not need to be directly movably connected to the housing 100. Then, when the mirror group 200 is driven to rotate about the first axis Z, it will not affect its rotation about the second axis Y. Similarly, when the mirror group 200 is driven to rotate about the second axis Y, it will not affect its rotation about the first axis Z, realizing the structural decoupling of the camera module. The anti-shake process of the mirror group 200 is easier to control, which is beneficial to improving the control accuracy. The mirror group 200 can accurately rotate along the corresponding compensation direction, which is beneficial to improving the anti-shake effect.

[0024] In the solution of the present application, one of the mirror group 200 and the adapter 300 is a rotating component S1, and the other is a rotating support component S2. Or, one of the adapter 300 and the housing 100 is a rotating component S1, and the other is a rotating support component S2. The rotating component S1 and the rotating support component S2 are rotationally engaged, enabling the rotating component S1 to rotate relative to the rotating support component S2. Specifically, the mirror group 200 is the rotating component S1 and the adapter 300 is the rotating support component S2, or the adapter 300 is the rotating component S1 and the mirror group 200 is the rotating support component S2, and the mirror group 200 can rotate relative to the adapter 300 about the first axis Z; the adapter 300 is the rotating component S1 and the housing 100 is the rotating support component S2, or the adapter 300 is the rotating support component S2 and the housing 100 is the rotating component S1, and the adapter 300 can rotate relative to the housing 100 about the second axis Y.

[0025] The structure in which the mirror group 200 and the adapter 300 are rotationally engaged may be the same as or different from the structure in which the rotational support member S2 and the housing 100 are rotationally engaged. The structure of the rotational engagement between the rotating member S1 and the rotational support member S2 will be described in detail below.

[0026] In an alternative embodiment, the camera module further includes a protruding structural member S01. The protruding structural member S01 is provided with an arc surface, and the axis of the arc surface is collinear with the rotation axis of the rotating member S1. At least one of the rotating member S1 and the rotational support member S2 is provided with a receiving groove S02. The protruding structural member S01 is received in the receiving groove S02, and the protruding structural member S01 and the receiving groove S02 are rotationally engaged through the arc surface. The protruding structural member S01 can rotate relative to the receiving groove S02 through the arc surface, thereby realizing the relative rotation between the rotating member S1 and the rotational support member S2.

[0027] Optionally, a part of one of the rotating member S1 and the rotational support member S2 can serve as the protruding structural member S01, and the other of the rotating member S1 and the rotational support member S2 is provided with the receiving groove S02; alternatively, the protruding structural member S01 is a separate component, and both the rotating member S1 and the rotational support member S2 are provided with the receiving groove S02. Among them, the receiving groove S02 can be a square groove, an arc groove 520, etc. The specific shape of the receiving groove S02 is not limited in the embodiments of the present application.

[0028] Optionally, one of the mirror group 200 and the adapter 300 is the rotating member S1, and the other is the rotational support member S2. The rotation axis of the rotating member S1 is the first axis Z. The mirror group 200 and the adapter 300 realize rotation about the first axis Z through the protruding structural member S01 and the receiving groove S02; one of the adapter 300 and the housing 100 is the rotating member S1, and the other is the rotational support member S2. The rotation axis of the rotating member S1 is the second axis Y. The adapter 300 and the housing 100 realize rotation about the second axis Y through the protruding structural member S01 and the receiving groove S02.

[0029] With this embodiment, the receiving groove S02 can directly receive the protruding structural member S01 to realize the rotational engagement between the rotating member S1 and the rotational support member S2. The protruding structural member S01 can also be disengaged from the receiving groove S02 to separate the rotating member S1 and the rotational support member S2, which facilitates the installation and disassembly of the rotating member S1, and further facilitates the maintenance and replacement of the rotating member S1 and the rotational support member S2, ensuring the anti-shake performance of the camera module.

[0030] Of course, in other embodiments, the camera module may not be provided with the protruding structural member S01 and the receiving groove S02, and the rotating member S1 and the rotational support member S2 may be rotationally engaged through a rotating shaft and a shaft hole.

[0031] In an alternative embodiment, the convex structural member S01 includes at least two first rolling members 400. The at least two first rolling members 400 are spaced apart, and the connecting line of the centers of the first rolling members 400 is collinear with the rotation axis of the rotating member S1. Each first rolling member 400 is provided with an arc surface. The first rolling member 400 can be, but is not limited to, a ball. The surface of the ball is a spherical surface, and a part of the spherical surface is an arc surface. The receiving groove S02 includes a first receiving groove 211 and a second receiving groove 310. The first receiving groove 211 is provided on the rotating member S1, and the second receiving groove 310 is provided on the rotating support member S2. The first receiving groove 211, the first rolling member 400, and the second receiving groove 310 correspond to each other one by one. Each first rolling member 400 is respectively received in the corresponding first receiving groove 211 and the corresponding second receiving groove 310.

[0032] That is to say, the first receiving groove 211 is opposite to the second receiving groove 310. The first rolling member 400 includes a first part and a second part. The first receiving groove 211 receives the first part of the first rolling member 400, and the second receiving groove 310 receives the second part of the first rolling member 400. The first rolling member 400 can rotate relative to the rotating member S1 and the rotating support member S2. Moreover, the connecting line of the centers of the first rolling members 400 forms a rotation axis, restricting the relative movement of the rotating member S1 and the rotating support member S2 in other directions, and realizing the rotation of the rotating member S1 and the rotating support member S2 around the connecting line of the centers of the first rolling members 400.

[0033] Optionally, the mirror group 200 is the rotating member S1, the adapter 300 is the rotating support member S2, and the number of the first rolling members 400 is two. The connecting line of the centers of the first rolling members 400 is collinear with the first axis Z. Of course, the number of the first rolling members 400 can be greater than two; refer to Figure 18 As shown, the adapter 300 is the rotating member S1, and the housing 100 is the rotating support member S2. The connecting line of the centers of the first rolling members 400 is collinear with the second axis Y.

[0034] By adopting this embodiment, the rotating member S1 and the rotating support member S2 achieve rotational cooperation through at least two first rolling members 400. Therefore, the rotating member S1 and the rotating support member S2 do not need to be directly rotationally mated, which facilitates the separation of the rotating member S1 and the rotating support member S2, and realizes the maintenance and replacement of the rotating member S1 and the rotating support member S2.

[0035] In another embodiment, the convex structural member S01 is an arc-shaped protrusion 510. The arc-shaped protrusion 510 is provided on one of the rotating member S1 and the rotating support member S2. The receiving groove S02 is an arc-shaped groove 520. The arc-shaped groove 520 is opened on the other of the rotating member S1 and the rotating support member S2. The arc-shaped protrusion 510 is rotationally mated with the arc-shaped groove 520.

[0036] Optionally, the adapter 300 is a rotating member S1, the housing 100 is a rotating support member S2, and one of the adapter 300 and the housing 100 is provided with an arc-shaped protrusion 510, and the other is provided with an arc-shaped groove 520. Further optionally, referring to Figures 5 - 8 As shown, the bottom of the adapter 300 is provided with an arc-shaped protrusion 510, and the inner bottom wall of the housing 100 is provided with an arc-shaped groove 520; or, referring to Figure 13 and Figure 14 As shown, the side of the adapter 300 is provided with an arc-shaped protrusion 510, and the inner side wall of the housing 100 is provided with an arc-shaped groove 520.

[0037] Optionally, the mirror group 200 is a rotating member S1, the adapter 300 is a rotating support member S2, and one of the lens barrel of the mirror group 200 and the adapter 300 is provided with an arc-shaped protrusion 510, and the other is provided with an arc-shaped groove 520. In this embodiment, one of the rotating member S1 and the rotating support member S2 is directly provided with the arc-shaped protrusion 510 as the protruding structural member S01, and the other is provided with the arc-shaped groove 520, without adding a separate component as the protruding structural member S01, which is beneficial to reducing the number of components of the camera module, simplifying the structure of the rotational fit, and is beneficial to reducing costs.

[0038] In a further embodiment, along the direction of the rotation axis of the rotating member S1, at least two arc-shaped protrusions 510 and arc-shaped grooves 520 are respectively arranged at intervals, and the arc-shaped protrusions 510 and the arc-shaped grooves 520 are in sliding fit one by one. Optionally, the arc diameters corresponding to each group of the cooperating arc-shaped protrusions 510 and arc-shaped grooves 520 may be equal or unequal. Referring to Figure 6 As shown, the adapter 300 and the housing 100 achieve rotational fit through the arc-shaped protrusion 510 and the arc-shaped groove 520, and along the second axis Y, one of the adapter 300 and the housing 100 is provided with at least two arc-shaped protrusions 510, and the other is provided with at least two arc-shaped grooves 520; the mirror group 200 and the adapter 300 achieve rotational fit through the arc-shaped protrusion 510 and the arc-shaped groove 520, and along the first axis Z, one of the lens barrel of the mirror group 200 and the adapter 300 is provided with at least two arc-shaped protrusions 510, and the other is provided with at least two arc-shaped grooves 520.

[0039] With this setting, through at least two groups of arc-shaped protrusions 510 and arc-shaped grooves 520, different positions of the rotating member S1 and different positions of the rotating support member S2 are respectively rotationally fitted, and the area of the rotational fit between the rotating member S1 and the rotating support member S2 is increased, which is beneficial to improving the rotational stability and enhancing the anti-shake stability.

[0040] Of course, in other embodiments, for the same rotating member S1 and rotating support member S2, the number of the arc-shaped protrusions 510 and the arc-shaped grooves 520 is one.

[0041] In a further embodiment, referring to Figure 7 As shown, a groove 540 is provided on one of the surface of the arc-shaped protrusion 510 and the groove wall surface of the arc-shaped groove 520. The camera module further includes a second rolling member 530. The second rolling member 530 is located in the groove 540, and the other of the surface of the arc-shaped protrusion 510 and the groove wall surface of the arc-shaped groove 520 contacts the second rolling member 530. Among them, the groove 540 can be a square groove, a circular groove, etc. The second rolling member 530 can be, but is not limited to, a ball. In short, the groove 540 can accommodate the second rolling member 530. A part of the second rolling member 530 is accommodated in the groove 540, and the other part of the second rolling member 530 is located outside the groove 540 and contacts the surface of the arc-shaped protrusion 510 or the groove wall surface of the arc-shaped groove 520.

[0042] Optionally, the groove 540 is provided on the surface of the arc-shaped protrusion 510, and the second rolling member 530 contacts the groove wall surface of the arc-shaped groove 520; or, the groove 540 is provided on the groove wall surface of the arc-shaped groove 520, and the second rolling member 530 contacts the surface of the arc-shaped protrusion 510.

[0043] With such a setting, the second rolling member 530 is added, and the second rolling member 530 rolls and contacts the surface of the arc-shaped protrusion 510 or the groove wall surface of the arc-shaped groove 520, converting the sliding friction between the arc-shaped protrusion 510 and the arc-shaped groove 520 into rolling friction, which is beneficial to reducing the friction force, ensuring the smooth rotational cooperation between the arc-shaped protrusion 510 and the arc-shaped groove 520, and more beneficial to the smooth rotational cooperation between the rotating member S1 and the rotating support member S2.

[0044] In a further embodiment, referring to Figure 7 As shown, in the direction around the rotation axis of the rotating member S1, and / or, in the direction where the rotation axis of the rotating member S1 is located, a plurality of the second rolling members 530 and the grooves 540 are respectively arranged at intervals, and the second rolling members 530 and the grooves 540 correspond to each other one by one.

[0045] Optionally, a plurality of the second rolling members 530 and the grooves 540 can be respectively arranged at intervals only in the direction around the rotation axis of the rotating member S1; or, a plurality of the second rolling members 530 and the grooves 540 can be respectively arranged at intervals only in the direction where the rotation axis of the rotating member S1 is located; or, a plurality of the second rolling members 530 and the grooves 540 are respectively arranged at intervals in the direction around the rotation axis of the rotating member S1 and in the direction where the rotation axis of the rotating member S1 is located.

[0046] With such a setting, the number of the second rolling members 530 and the grooves 540 is relatively large. Different positions of the arc-shaped protrusions 510 and different positions of the arc-shaped grooves 520 achieve rolling contact respectively through different second rolling members 530, which is beneficial to further reduce the friction force, further beneficial to the smooth rotational cooperation between the arc-shaped protrusions 510 and the arc-shaped grooves 520, and more beneficial to the smooth rotational cooperation between the rotating member S1 and the rotating support member S2.

[0047] Certainly, in other embodiments, for the same group of arc-shaped protrusions 510 and arc-shaped grooves 520, the number of the second rolling members 530 and the grooves 540 is one each.

[0048] In an alternative embodiment, referring to Figure 3 As shown, the mirror group 200 includes a mirror 220. The mirror 220 is provided with a reflecting surface 221. Both the first axis Z and the second axis Y pass through the center 221a of the reflecting surface 221. At this time, the rotation radius of the preset position of the adapter 300 is the distance between the preset position and the center 221a of the reflecting surface 221. Optionally, the reflecting surface 221 may be a rectangular structure, and the center 221a of the reflecting surface 221 is the intersection point of the two diagonals of the rectangular structure; the reflecting surface 221 may also be a triangular structure, a pentagonal structure, etc. In short, both the first axis Z and the second axis Y pass through the geometric center of the reflecting surface 221.

[0049] With such a setting, both the first axis Z and the second axis Y pass through the optical center of the mirror group 200, which is beneficial to reducing light deviation, reducing imaging blur, improving the stability and reliability of the optical performance, and making the optical effect better.

[0050] In another embodiment, neither the first axis Z nor the second axis Y passes through the center 221a of the reflecting surface 221. Referring to Figure 25 and Figure 26 As shown, the second axis Y is parallel to the reflecting surface 221, and the adapter 300 is provided with a displacement detection element 310a. During the rotation of the adapter 300 relative to the housing 100 around the second axis Y, the displacement detection element 310a can detect the amount of rotational displacement. Moreover, the rotation radius of the displacement detection element 310a is greater than the distance between the displacement detection element 310a and the center 221a of the reflecting surface 221.

[0051] Optionally, the displacement detection element 310a may include a Hall sensing element and a sensing magnet. The sensing magnet provides a magnetic field, and the Hall sensing element is used to sense the change in the magnetic field. The relative displacement between the Hall sensing element and the sensing magnet is feedback through the change in the magnetic field. One of the Hall sensing element and the sensing magnet may be disposed on the adapter 300, the position of the other is fixed, and the other may be disposed on the housing 100. Of course, the displacement detection element 310a may also adopt other detection elements other than the Hall sensing element and the sensing magnet, as long as it can detect the rotational displacement amount of the adapter 300.

[0052] Optionally, referring to Figure 25 As shown, the first axis Z and the second axis Y may pass through the center of the exit surface of the mirror 220. The exit surface may be a concave surface or a flat surface. The specific type of the mirror 220 is not limited in the embodiments of the present application. At this time, the rotational radius of the displacement detection element 310a disposed on the adapter 300 is L2, and the distance between the displacement detection element 310a and the center 221a of the reflection surface 221 is L1, and L2 is greater than L1.

[0053] With such a setting, compared with the solution where the first axis Z and the second axis Y pass through the center 221a of the reflection surface 221, when the adapter 300 rotates the same angle relative to the housing 100, the rotational radius of the displacement detection element 310a is larger, the rotational displacement amount of the displacement detection element 310a is also larger, and the displacement detection element 310a can more easily detect the displacement change amount, which is beneficial to improving the detection accuracy.

[0054] In the solution of the present application, the camera module further includes a first magnetic member 610 and a second magnetic member 620. The first magnetic member 610 is disposed on the rotating member S1, and the second magnetic member 620 is disposed on the rotating support member S2. The first magnetic member 610 and the second magnetic member 620 are magnetically coupled, and the rotating member S1 and the rotating support member S2 are connected through the magnetically coupled first magnetic member 610 and second magnetic member 620.

[0055] Among them, the first magnetic member 610 and the second magnetic member 620 may be electromagnets or permanent magnets. Their magnetic attractions are different to achieve attraction between opposite poles. The first magnetic member 610 and the second magnetic member 620 may be in a block structure, a sheet structure, etc. The specific structures of the first magnetic member 610 and the second magnetic member 620 are not limited in the embodiments of the present application. The first magnetic member 610 and the rotating member S1, and the second magnetic member 620 and the rotating support member S2 may be fixedly connected by welding, bonding, etc.

[0056] Optionally, referring to Figure 5 and Figure 8As shown, the rotating component S1 is the mirror group 200, the rotating support component S2 is the adapter 300, and the mirror group 200 and the adapter 300 are rotationally matched through at least two first rolling components 400. At this time, both the first magnetic component 610 and the second magnetic component 620 are located between two of the first rolling components 400; reference Figure 8 As shown, the rotating component S1 is the adapter 300, the rotating support component S2 is the housing 100, the adapter 300 is provided with the first magnetic component 610, and the housing 100 is provided with the second magnetic component 620.

[0057] In this embodiment, relying on the magnetically attracted first magnetic component 610 and second magnetic component 620, there is an attractive force between the rotating component S1 and the rotating support component S2, achieving stable contact between the rotating component S1 and the rotating support component S2, preventing the rotating component S1 and the rotating support component S2 from separating. At the same time, the rotating component S1 and the rotating support component S2 are not relatively fixed, ensuring smooth rotational matching between the rotating component S1 and the rotating support component S2.

[0058] Of course, in other embodiments, the rotating component S1 and the rotating support component S2 can be connected through other structures other than the first magnetic component 610 and the second magnetic component 620.

[0059] In the solution of the present application, the camera module further includes a driving component 700. The driving component 700 is connected to the rotating component S1, and the driving component 700 drives the rotating component S1 to rotate relative to the rotating support component S2. The driving component 700 can be a driving source such as a motor that can provide rotational power. The specific type of the driving component 700 is not limited in the embodiment of the present application.

[0060] Optionally, the mirror group 200 is the rotating component S1, the adapter 300 is the rotating support component S2, the driving component 700 is the first driving component 710, and the first driving component 710 drives the mirror group 200 to rotate relative to the adapter 300 about the first axis Z; the adapter 300 is the rotating component S1, the housing 100 is the rotating support component S2, the driving component 700 is the second driving component 720, and the second driving component 720 drives the adapter 300 or the mirror group 200 to rotate relative to the housing 100 about the second axis Y. Of course, the driving component 700 can include the first driving component 710 and the second driving component 720. Relying on the first driving component 710 to drive the mirror group 200 relative to the adapter 300, and at the same time, relying on the second driving component 720 to drive the adapter 300 or the mirror group 200 to rotate relative to the housing 100 about the second axis Y.

[0061] With such a setting, the camera module is provided with the driving component 700, and relying on the driving component 700 to drive the rotating component S1 to rotate is beneficial for the rotating component S1 to rotate rapidly along the compensation direction, improving the anti-shake efficiency.

[0062] In an alternative embodiment, the driving member 700 includes an opposing third magnetic member 701 and an energized coil 702. One of the third magnetic member 701 and the energized coil 702 is connected to the rotating member S1. When the energized coil 702 is energized, one of the third magnetic member 701 and the energized coil 702 drives the rotating member S1 to rotate relative to the rotating support member S2.

[0063] Specifically, it can be that the third magnetic member 701 is connected to the rotating member S1, the position of the energized coil 702 is fixed, the energized coil 702 is arranged in the housing 100, and when the energized coil 702 is energized, the third magnetic member 701 moves relative to the energized coil 702; or, the energized coil 702 is connected to the rotating member S1, the position of the third magnetic member 701 is fixed, the third magnetic member 701 is arranged in the housing 100, and when the energized coil 702 is energized, the energized coil 702 moves relative to the third magnetic member 701.

[0064] Optionally, the rotating member S1 is the mirror group 200, and the rotating support member S2 is the adapter 300. Refer to Figures 10 - 12 As shown, the first driving member 710 includes two sets of the third magnetic member 701 and the energized coil 702. Along the direction of the second axis Y, the mirror group 200 has an opposite first side and second side, and these two sets of the third magnetic member 701 and the energized coil 702 are respectively located on the first side and the second side. Refer to Figure 11 As shown in the top view structure diagram, the energizing directions of the two sets of energized coils 702 are opposite, so that the third magnetic member 701 located on the first side bears a downward Lorentz force, and the third magnetic member 701 located on the second side bears an upward Lorentz force. Each set of the third magnetic member 701 drives the mirror group 200 to rotate counterclockwise around the first axis Z; Refer to Figure 12 As shown in the top view structure diagram, by changing the energizing directions of the two sets of energized coils 702, the third magnetic member 701 located on the first side bears an upward Lorentz force, and the third magnetic member 701 located on the second side bears a downward Lorentz force. Each set of the third magnetic member 701 drives the mirror group 200 to rotate clockwise around the first axis Z.

[0065] Optionally, the rotating member S1 is the adapter 300, and the rotating support member S2 is the housing 100. Refer to Figure 14 As shown, the second driving member 720 includes two sets of the third magnetic member 701 and the energized coil 702. The energizing directions of the two sets of energized coils 702 are the same. When the two sets of energized coils 702 are in the first energized state, the two sets of the third magnetic member 701 bear upward Lorentz forces, and each set of the third magnetic member 701 drives the adapter 300 along Figure 14shown in the figure rotates clockwise about the second axis Y; by changing the energization directions of the two sets of energized coils 702, the two sets of third magnetic members 701 can withstand a downward Lorentz force, and each set of third magnetic members 701 drives the adapter 300 to rotate counterclockwise about the second axis Y. Of course, the adapter 300 and the housing 100 can also rotate about the second axis Y by only one set of third magnetic members 701 and energized coils 702.

[0066] Compared with using a motor with a complex structure as the driving member 700, the structures of the third magnetic member 701 and the energized coil 702 are simple, which is beneficial to reducing the occupied space of the driving member 700 and the volume of the camera module.

[0067] In another alternative embodiment, the driving member 700 includes a deformation element 703, and the deformation element 703 is connected to the rotating member S1. When the deformation element 703 deforms, it can drive the rotating member S1 to rotate relative to the rotating support member S2. Among them, the deformation element 703 can be a temperature-induced deformation element, and the temperature-induced deformation element can be a temperature-sensitive sheet, a shape memory alloy, etc. When the temperature-induced deformation element is heated, the temperature-induced deformation element deforms and drives the rotating member S1 to rotate; or, the deformation element 703 can be an electro-induced deformation element, and the electro-induced deformation element can be a bimetallic sheet, a piezoelectric sheet, etc. When the electro-induced deformation element is energized, the electro-induced deformation element deforms and drives the rotating member S1 to rotate. Of course, the deformation element 703 can also be of other types.

[0068] Optionally, referring to Figure 6 shown in the figure, the first driving member 710 is a deformation element 703. The deformation element 703 includes a first shape memory alloy wire 703a and a second shape memory alloy wire 703b. The first shape memory alloy wire 703a and the second shape memory alloy wire 703b are respectively located on the first side and the second side of the mirror group 200. The first shape memory alloy wire 703a and the second shape memory alloy wire 703b cooperate to drive the mirror group 200 to rotate about the first axis Z. Fixing disks 703c are provided at both ends of the first shape memory alloy wire 703a and both ends of the second shape memory alloy wire 703b. Each fixing disk 703c can be fixed to the housing 100 so that the positions of both ends of the first shape memory alloy wire 703a and both ends of the second shape memory alloy wire 703b are fixed. The middle positions of the first shape memory alloy wire 703a and the second shape memory alloy wire 703b are respectively connected to the mirror group 200. Further optionally, first hanging positions are provided on both sides of the mirror group 200, and the first shape memory alloy wire 703a and the second shape memory alloy wire 703b can be hung into the corresponding first hanging positions.

[0069] Thus, when the first shape memory alloy wire 703a relaxes and the second shape memory alloy wire 703b contracts, the deformation element 703 drives the mirror group 200 to rotate clockwise around the first axis Z as shown in Figure 6 the figure, and vice versa. When the first shape memory alloy wire 703a contracts and the second shape memory alloy wire 703b relaxes, the deformation element 703 drives the mirror group 200 to rotate counterclockwise around the first axis Z.

[0070] Optionally, as shown in Figure 7 the figure, the second driving member 720 is the deformation element 703. The deformation element 703 includes a first shape memory alloy wire 703a and a second shape memory alloy wire 703b. Both the first shape memory alloy wire 703a and the second shape memory alloy wire 703b are located on the same side of the mirror group 200. The first shape memory alloy wire 703a and the second shape memory alloy wire 703b cooperate to drive the adapter 300 and the mirror group 200 to rotate around the second axis Y. Fixing disks 703c are provided at both ends of the first shape memory alloy wire 703a and both ends of the second shape memory alloy wire 703b. Each fixing disk 703c can be fixed to the housing 100 to fix the positions of both ends of the first shape memory alloy wire 703a and both ends of the second shape memory alloy wire 703b. The middle positions of the first shape memory alloy wire 703a and the second shape memory alloy wire 703b are connected to the mirror group 200 or the adapter 300, and the contraction directions of the first shape memory alloy wire 703a and the second shape memory alloy wire 703b are opposite. Further optionally, second hanging positions are provided on the side of the mirror group 200 or the adapter 300, and the first shape memory alloy wire 703a and the second shape memory alloy wire 703b can be hung into the corresponding second hanging positions.

[0071] Thus, when the first shape memory alloy wire 703a contracts and the second shape memory alloy wire 703b relaxes, the deformation element 703 drives the mirror group 200 and the adapter 300 to rotate clockwise around the second axis Y as shown in Figure 7 the figure, and vice versa. When the first shape memory alloy wire 703a relaxes and the second shape memory alloy wire 703b contracts, the deformation element 703 drives the mirror group 200 and the adapter 300 to rotate counterclockwise around the second axis Y.

[0072] Compared with using a motor with a complex structure as the driving member 700, the structure of the deformation element 703 is simple, which is beneficial to reducing the occupied space of the driving member 700 and reducing the volume of the camera module.

[0073] Of course, in other embodiments, other driving methods other than the cooperation between the energized coil 702 and the third magnetic member 701 and the driving of the deformation element 703 may be adopted to drive the rotating member S1 to rotate relative to the rotating support member S2.

[0074] In the embodiments of the present application, with reference to Figures 4 - 8 shown, or with reference to Figures 15 - 19 shown, both the first driving member 710 and the second driving member 720 are deformation elements 703; or, with reference to Figures 9 - 14 shown, both the first driving member 710 and the second driving member 720 adopt the third magnetic member 701 and the energized coil 702; or, with reference to Figures 20 - 24 shown, the first driving member 710 adopts the third magnetic member 701 and the energized coil 702, and the second driving member 720 adopts the deformation element 703. Of course, it is also possible that the first driving member 710 adopts the deformation element 703 and the second driving member 720 adopts the third magnetic member 701 and the energized coil 702. The embodiments of the present application do not limit this.

With reference to Figure 7 shown, the arc-shaped groove 520 is provided on the frame body 110; in combination with Figures 10 - 12 shown, the mirror group 200 and the adapter 300 achieve relative rotation by relying on the third magnetic member 701 and the energized coil 702. The energized coil 702 can be provided on the outer cover 121. With reference to Figure 13 shown, the adapter 300 and the housing 100 achieve relative rotation by relying on the third magnetic member 701 and the energized coil 702. The third magnetic member 701 can be provided on the rear cover 122.

[0076] In an alternative embodiment, with reference to Figure 18 and Figure 19 shown, the adapter 300 and the housing 100 are rotationally engaged through the first rolling member 400. The imaging module further includes a stopper 111. The stopper 111 is connected to the housing 100. The stopper 111 and the adapter 300 are in limit cooperation to limit the freedom of movement of the adapter 300 and prevent the first rolling member 400 between the adapter 300 and the housing 100 from coming out. Optionally, the stopper 111 and the frame body 110 can be connected by welding, bonding, etc. The embodiments of the present application do not limit the specific structure of the stopper 111.

[0077] In the solution of the present application, the camera module further includes an elastic reset member 800. The elastic reset member 800 is connected to the rotating member S1. During the process of the driving member 700 driving the rotating member S1 to rotate relative to the rotating support member S2, the elastic reset member 800 undergoes elastic deformation.

[0078] Optionally, referring to Figure 6 As shown, the elastic reset member 800 is a first elastic member 810. The first elastic member 810 can be but is not limited to a spring. The first elastic member 810 is connected to the mirror group 200. During the process of the first driving member 710 driving the mirror group 200 to rotate around the first axis Z relative to the adapter 300, the first elastic member 810 undergoes elastic deformation. When the driving force of the first driving member 710 disappears, the first elastic member 810 restores its elastic deformation and drives the mirror group 200 to reverse and reset around the first axis Z; referring to Figure 7 As shown, the elastic reset member 800 is a second elastic member 820. The second elastic member 820 can be but is not limited to a spring. The second elastic member 820 is connected to the adapter 300. During the process of the second driving member 720 driving the adapter 300 to rotate around the second axis Y relative to the housing 100, the second elastic member 820 undergoes elastic deformation. When the driving force of the second driving member 720 disappears, the second elastic member 820 restores its elastic deformation and drives the adapter 300 and the mirror group 200 to reverse and reset around the second axis Y. Of course, the elastic reset member 800 can include both the first elastic member 810 and the second elastic member 820.

[0079] With such a setting, after the anti-shake action is completed, relying on the elastic force of the elastic reset member 800, the rotating member S1 is timely and accurately driven to rotate and reset relative to the rotating support member S2, ensuring that the rotating member S1 can return to the reference position after each anti-shake operation, preparing for the next anti-shake action, which is beneficial to improving the reliability and accuracy of the anti-shake performance.

[0080] Of course, in other embodiments, the camera module may not be provided with the elastic reset member 800, and other driving structures can be relied on to drive the rotating member S1 to reverse and reset.

[0081] Based on the camera module disclosed in the present application, the embodiment of the present application further includes a device housing and the above-mentioned camera module, and the camera module is disposed in the device housing. Optionally, the camera module can be disposed inside the device housing. Of course, other functional components such as a battery module and a display module can also be disposed in the device housing to expand the functions of the electronic device.

[0082] In this embodiment, in the camera module of the electronic device, the mirror group 200 is not directly and movably connected to the housing through the adapter 300. When the mirror group 200 is driven to rotate about the first axis Z, it will not affect its rotation about the second axis Y. Similarly, when the mirror group 200 is driven to rotate about the second axis Y, it will not affect its rotation about the first axis Z, realizing the structural decoupling of the camera module. The anti-shake process of the mirror group 200 is easier to control, which is beneficial to improving the control accuracy. The mirror group 200 can accurately rotate along the corresponding compensation direction, which is beneficial to improving the anti-shake effect.

[0083] The electronic device disclosed in the embodiment of the present application may be a smart phone, a tablet computer, an e-book reader, a wearable device, an electronic game console, etc. The embodiment of the present application does not limit the specific type of the electronic device.
