In a common periscopic imaging module, an optical anti-shake effect is generally achieved by controlling a rotation angle of an optical path deflecting element. However, in the anti-shake process of the optical path folding element, the assembly is required to reserve corresponding spaces in two orthogonal directions perpendicular to the rotating shaft so as to allow the optical path folding element to rotate, and the end of the optical path folding element is prevented from being blocked by the housing of the assembly when rotating. For this reason, the size of the image pickup assembly having the above-mentioned anti-shake structure in the light incident direction is generally large, and its application to the apparatus often results in that the thickness of the apparatus is difficult to be reduced, thereby being disadvantageous to the miniaturization design of the apparatus. Therefore, the application provides a camera shooting assembly, a camera shooting module and electronic equipment to solve the problems.

Referring to fig. 1 and fig. 2, an embodiment of the present invention provides a camera assembly 10 with an optical anti-shake effect, where the camera assembly 10 includes a housing 110, a lens 120, and an optical path deflecting element 130. Wherein the lens 120 is mounted on the housing 110 and has an optical axis 122, and the lens 120 is used for converging incident light. The optical path folding element 130 is also mounted on the housing 110, the optical path folding element 130 includes a reflection element 132 and a first driving element 133, the reflection element 132 is disposed on an object side of the lens 120, the reflection element 132 is configured to reflect an incident light beam to the lens 120, the first driving element 133 is configured to act on the reflection element 132, and the first driving element 133 can drive the reflection element 132 to move along a direction parallel to the optical axis 122 of the lens 120, so as to achieve an optical anti-shake effect along the direction. The image pickup unit 10 may be a periscopic lens.

For convenience of description, reference directions are established for the camera assembly 10, and the reference directions are a first direction a, a second direction B and a third direction C, respectively, wherein any two directions are perpendicular to each other. The direction parallel to the optical axis 122 is a first direction a, the light incident direction of the image capturing module 10 is a third direction C, a part of light from the object can be incident on the reflective member 132 and reflected to the lens 120 along the third direction C, and the second direction B is perpendicular to the first direction a and the third direction C. The reflection member 132 can reflect the light incident in the parallel third direction C to the lens 120.

The lens 120 includes at least one lens, wherein when the lens 120 includes more than two lenses, each lens is coaxially disposed, so that the optical axis 122 of the lens can be regarded as the optical axis 122 of the lens 120, and the optical axis 122 described below refers to the optical axis 122 of the lens 120. It should be noted that, in the process of optical anti-shake, when it is described that the reflective element 132 can move along the direction parallel to the optical axis 122 under the action of the first driving element 133, in some embodiments, there may also be a movement component of the reflective element 132 in other directions, for example, there may be a movement component of the reflective element 132 in both directions parallel to the optical axis 122 and perpendicular to the optical axis 122.

In the image capturing module 10, the reflective element 132 disposed on the object side of the lens 120 is driven by the first driving element 133 to move along a direction parallel to the optical axis 122 of the lens 120, so as to achieve an anti-shake effect along the optical axis 122. Compared to the rotary optical anti-shake structure, the camera assembly 10 only needs to reserve a moving space in the direction of the reflective element 132 parallel to the optical axis 122 of the lens 120 to allow the reflective element 132 to move, and does not need to reserve a moving space in the light incident direction of the reflective element 132. Therefore, when the camera module 10 is applied to an electronic device 30 such as a smart phone or a tablet computer, no extra movement space needs to be reserved in the device in the light incident direction of the camera module 10, which is beneficial to reducing the thickness of the device and promoting the miniaturization design of the device.

In addition, since the reflective member 132 adopts a movable optical anti-shake design, after the reflective member 132 is moved to compensate for the shake distance, light from each position of the target area can be incident on the lens 120 through an original path before shake, so that the paths before and after the anti-shake adjustment of the incident light beam are overlapped to the maximum extent, thereby improving the imaging consistency in the anti-shake process, maintaining the resolution of the system, and maintaining higher anti-shake compensation accuracy. For the optical anti-shake structure using the rotary type, after the reflection structure rotates by a corresponding angle, the deflection angle of the reflected light reaching the lens 120 is twice the rotation angle, so that the incident light beam has a larger deviation from the path of the incident light beam entering the lens 120 before and after the anti-shake adjustment, which results in the decrease of the resolution of the system. Therefore, the anti-shake compensation accuracy can be improved by adopting a mobile anti-shake design for the reflection member 132.

In some embodiments, the housing 110 defines an accommodating cavity 112, the reflector 132 and the lens 120 are disposed in the accommodating cavity 112, the housing 110 further defines a light-passing hole 114, the light-passing hole 114 communicates with the accommodating cavity 112, the light-passing hole 114 is located on one side of the reflector 132 along the third direction C, and the reflector 132 is configured to reflect the light beam incident from the light-passing hole 114 to the lens 120.

In some embodiments, the reflector 132 may be a plate reflector, a right triangular prism, or other common reflective elements. For example, in the embodiment shown in fig. 1, the reflecting member 132 is a right triangular prism, one right-angled surface of the right triangular prism faces the lens 120, and an inclined surface of the right triangular prism is used for reflecting the incident light beam to the lens 120. When the housing 110 is provided with the light passing hole 114 at one side of the reflection member 132 along the third direction C, the axial direction of the light passing hole 114 is parallel to the third direction C. And when the reflector 132 is a right-angle triple prism, a right-angle surface of the reflector 132 faces the lens 120, another right-angle surface faces the light-passing hole 114, an inclined surface of the reflector 132 serves as a reflecting surface to reflect the incident light beam to the lens 120, and the inclined surface of the reflector 132 is a plane and forms an included angle of 45 degrees with the optical axis 122 of the lens 120.

The design of the first driving element 133 may be various, for example, it may be a linear motor, or a matching structure of a coil and a magnet, or it may also be a piezoelectric ceramic, a shape memory alloy, etc., as long as it can act on the reflecting element 132 and drive the reflecting element 132 to move along the first direction a, which is not exhaustive here.

For example, in some embodiments, the first driving member 133 includes a first magnet 1332 and a first coil 1334, one of the first magnet 1332 and the first coil 1334 is disposed on the reflector 132, and the other is disposed on the housing 110, and the first coil 1334 can generate a magnetic field and interact with the first magnet 1332 when being powered on, so as to apply a force along the first direction a to the reflector 132, so as to drive the reflector 132 to translate along the first direction a. By controlling the current flowing direction of the first coil 1334, the reflector 132 can be controlled to move back and forth in the first direction a, so as to achieve the optical anti-shake effect along the direction. The positions of the first magnet 1332 and the first coil 1334 relative to the reflector 132 may be various, as long as the reflector 132 is not obstructed to reflect the incident light to the lens 120.

Further, the reflection element 132 is connected to at least one first magnet 1332 respectively on the opposite sides in the second direction B, at least one first coil 1334 is respectively disposed in the region of the casing 110 facing the opposite sides of the reflection element 132 in the second direction B, and the first coil 1334 on the same side of the reflection element 132 can cooperate with the first magnet 1332 to apply an acting force to the reflection element 132 along the direction parallel to the optical axis 122. In some embodiments, the central axis of the first coil 1334 faces the first magnet 1332 on the same side of the reflector 132, so as to enhance the strength between the magnetic field of the coil and the magnet. Further, in some embodiments, the north-south pole direction of the first magnet 1332 is perpendicular or nearly perpendicular to the central axis of the first coil 1334 in a corresponding set of the first magnet 1332 and the first coil 1334. In some embodiments, the axial direction of the first coil 1334 is parallel or nearly parallel to the second direction B, the first coil 1334 being axially spaced from the first magnet 1332.

Referring to fig. 2 and 3 in particular, in some embodiments, the first driving member 133 includes two first coils 1334 and two first magnets 1332, wherein one first coil 1334 and one first magnet 1332 are disposed at one end of the reflecting member 132 in the second direction B, and the other first coil 1334 and the other first magnet 1332 are disposed at the other end of the reflecting member 132 opposite to the second direction B. The two first magnets 1332 are fixed on the reflector 132, the two first coils 1334 are fixed on the casing 110, each first coil 1334 corresponds to one first magnet 1332 in the second direction B, and the axial directions of the two first coils 1334 are parallel to the second direction B. The above design can prevent the first driving element 133 from blocking the incident light path (parallel to the third direction C) and the emergent light path (parallel to the first direction a) of the reflecting element 132. In the above design, the coil is fixed to the housing 110, and the magnet is fixed to the reflector 132, so that it is possible to prevent the conductive wire connected to the first coil 1334 from being torn off when the reflector 132 moves due to the coil being provided on the reflector 132. In some embodiments, the number of the first coil 1334 and the first magnet 1332 is not limited to two, and may be four, six, and the like. In some embodiments, the driving structure formed by the first coil 1334 and the first magnet 1332 is disposed in the camera module 10 in an axisymmetric relationship, so as to make the acting force applied to the reflective element 132 more balanced and improve the movement stability of the reflective element 132.

In some embodiments, the first driving member 133 further includes a first elastic sheet (not shown), the first elastic sheet connects the housing 110 and the reflecting member 132, and the first elastic sheet is capable of applying an elastic force to the reflecting member 132 to return along the first direction a. At least one of the two opposite sides of the reflection element 132 along the first direction a may be provided with a first elastic sheet, and the first elastic sheet is fixedly connected to the casing 110 and may abut against or be fixedly connected to the reflection element 132. The first elastic sheet may be any common elastic structure, as long as the elastic force capable of resetting along the first direction a can be applied to the reflecting member 132 when the reflecting member 132 deviates from the equilibrium position.

As described above, the single-axis anti-shake effect in the first direction a can be provided to the image pickup device 10 by controlling the movement of the reflector 132 in the first direction a.

In some embodiments, the camera module 10 includes a lens driving element disposed in the housing 110, and the lens driving element can drive the lens 120 to move in the first direction a and/or the second direction B. The lens group driving member can only use one group of driving structures to move the lens 120 in the first direction a and the second direction B, or two or more groups of driving structures can independently realize the movement of the lens 120 in different directions.

Referring to fig. 3, in some embodiments of the present application, the lens group driving unit includes a second driving unit 140 disposed on the housing 110, and the second driving unit 140 can drive the lens 120 to move along the second direction B. By controlling the reflector 132 in the camera module 10 to move along the first direction a, and in combination with controlling the lens 120 to move along the second direction B, the camera module 10 can have a dual-axis anti-shake effect along the first direction a and the second direction B. In addition, since the reflective member 132 and the lens 120 can respectively realize translational anti-shake in different directions, the problem of integral rotation of the imaging can be prevented.

In some embodiments, when the housing 110 has the light passing hole 114, an axial direction of the light passing hole 114 is a light incident direction of the image capturing device 10, and the axial direction of the light passing hole 114 is perpendicular to the first direction a and parallel to the third direction C, so that the incident light beam enters the reflection element 132 through the light passing hole 114 and is reflected by the reflection element 132 to the lens 120.

The reflective element 132 has a reflective surface, in some embodiments, the reflective surface is a plane and parallel to the second direction B, and the second driving element 140 can drive the lens 120 to move along a direction perpendicular to the optical axis 122 and parallel to the reflective surface, that is, the second driving element 140 can drive the lens 120 to move in the second direction B.

As mentioned above, the design of the first driving element 133 and the second driving element 140 may be various, for example, they may be a linear motor or a matching structure of a coil and a magnet, or they may be piezoelectric ceramics, shape memory alloy, etc., as long as they can act on the lens 120 and drive it to move along the second direction B, which is not exhaustive here.

Taking the matching structure of the coils and the magnets as an example, in some embodiments, the second driving element 140 includes a second magnet 142 and a second coil 144, one of the second magnet 142 and the second coil 144 is disposed on the lens 120, and the other is disposed on the housing 110, and the second coil 144 can generate a magnetic field and interact with the second magnet 142 when being energized, so as to apply a force along the second direction B to the reflecting element 132, so as to drive the reflecting element 132 to translate along the second direction B. The lens 120 can be controlled to move back and forth in the second direction B by controlling the flowing direction of the current in the second coil 144, so as to achieve the optical anti-shake effect along the direction. The positions of the second magnet 142 and the second coil 144 relative to the lens 120 may be various, as long as they can interact to drive the lens 120 to move in the second direction B.

In particular, referring to fig. 3, in some embodiments, the second driving member 140 includes two second coils 144 and two second magnets 142, the two second magnets 142 are fixed to the image end of the lens 120 and spaced apart in the second direction B, the two second coils 144 are fixed to the housing 110 and also spaced apart in the second direction B, the axial directions of the two second coils 144 are parallel to the first direction a, each second magnet 142 corresponds to one second coil 144 in the first direction a, and the central axis of the second coil 144 faces the second magnet 142 acting on. In the above design, the coil is fixed to the housing 110, and the magnet is fixed to the lens 120, so that the coil is not disposed on the lens 120, which may cause the lens 120 to break the conductive wire of the coil when moving. In some embodiments, the second coil 144 has an axial direction parallel or nearly parallel to the first direction a, and the second coil 144 is axially spaced from the second magnet 142 (the first direction a).

Further, in some embodiments, the north-south pole of the second magnet 142 is perpendicular or nearly perpendicular to the central axis of the second coil 144 in a corresponding set of the second magnet 142 and the second coil 144.

In addition, in some embodiments, the camera assembly 10 further includes a second elastic sheet (not shown), where the second elastic sheet connects the housing 110 and the lens 120, and the second elastic sheet is capable of applying an elastic force to the lens 120 to return along the second direction B. Specifically, in an embodiment, a second elastic sheet may be disposed on at least one of two opposite sides of the lens 120 along the second direction B, and the second elastic sheet is fixedly connected to the housing 110 and may abut against or be fixedly connected to the lens 120. The second elastic sheet may be any common elastic structure, as long as an elastic force capable of resetting along the second direction B is applied to the lens 120 when the lens 120 deviates from the equilibrium position.

As described above, since the moving direction of the lens 120 is perpendicular to the moving direction of the reflection portion, the moving cooperation between the two can provide the image pickup module 10 with the biaxial anti-shake effect. And because the reflecting piece 132 and the lens 120 can respectively realize translational anti-shake in different directions, the problem of integral rotation of the imaging can be prevented. In addition, the movement of the lens 120 and the reflection member 132 is mainly concentrated in a plane perpendicular to the light incidence direction, so that the camera module 10 does not need to provide a movement space to match the movement of the reflection member 132 and the lens 120 in the third direction C, and therefore the camera module 10 can keep a small structural size in the light incidence direction.

On the other hand, in addition to the optical anti-shake effect, in order to improve the shooting effect on objects at different shooting object distances, the camera assembly 10 in some embodiments is further provided with a focusing structure.

Referring to fig. 4, in some embodiments, the lens group driving device further includes a third driving device 150, and the third driving device 150 is disposed on the housing 110 and can drive the lens 120 to move along a direction parallel to the optical axis 122. As the first driving member 133 is designed, the third driving member 150 may be designed in various ways, such as a linear motor or a matching structure of a coil and a magnet, as long as it can act on the lens 120 and drive it to move along the first direction a, which is not exhaustive here. It should be noted that the lens group driving element for driving the lens 120 to move can only include the second driving element 140 or the third driving element 150, so that the lens 120 can move along a specific direction; alternatively, the lens group driving unit may include both of them, so as to provide the lens 120 with the capability of moving along the first direction a and the second direction B.

The third driving element 150 includes a third magnet 152 and a third coil 154, one of the third magnet 152 and the third coil 154 is disposed on the lens 120, and the other is disposed on the housing 110, and the third coil 154 can interact with the third magnet 152 when being powered on, so as to apply an acting force to the lens 120 along a direction parallel to the optical axis 122, and further drive the lens 120 to translate along the first direction a. The third coil 154 can generate a magnetic field to act on the third magnet 152 after being energized, and the interaction between the third coil and the third magnet can drive the lens 120 to move, that is, the lens 120 is driven to move in the first direction a.

Specifically, the third driving element 150 may be a common focusing driving structure, for example, a third coil 154 is disposed around the lens 120, a third magnet 152 is disposed in the housing 110, and the third coil 154 passes through an electric current to generate a magnetic field to act on the third magnet 152, so as to provide an acting force along the first direction a for the lens 120, so as to drive the lens 120 to translate along the first direction a to achieve a focusing effect. In other embodiments, the third coil 154 may be fixed to the housing 110, the third coil 154 may surround the lens barrel along the circumferential direction of the lens barrel, and the third magnet 152 may be fixed to the lens 120. In addition to surrounding the third coil 154 around the lens barrel, reference may also be made to the arrangement of the first driving element 133 with respect to the reflection element 132, for example, in some embodiments, the third driving element 150 includes two third magnets 152 and two third coils 154, wherein one third coil 154 and one third magnet 152 are disposed on one side of the lens 120 in the second direction B, the other third coil 154 and the other third magnet 152 are disposed on the other side of the lens 120 opposite to the second direction B, the two third magnets 152 are respectively fixed to the lens 120, the two third coils 154 are respectively fixed to the housing 110, and the third coil 154 and the third magnet 152 disposed on the same side of the lens 120 are mutually matched.

Further, in some embodiments, the north-south pole of the third magnet 152 is oriented perpendicular or nearly perpendicular to the central axis of the third coil 154 in a corresponding set of the third magnet 152 and the third coil 154. In addition, in some embodiments, in each set of corresponding third magnets 152 and third coils 154, the third coils 154 are axially spaced from the third magnets 152 to prevent interference therebetween during relative movement. In addition to providing the second driving member 140 and the third driving member 150 which are operated independently to control the lens 120 to move in the second direction B and the first direction a, respectively, the driving structure can be further simplified. In some embodiments, the housing 110 is provided with a second coil 144 and a third coil 154, and the lens 120 is provided with a fourth magnet, and both the second coil 144 and the third coil 154 can act on the fourth magnet by an electric field generated by energization. When the second coil 144 acts on the fourth magnet, the fourth magnet can drive the lens 120 to move in the second direction B; when the third coil 154 acts on the fourth magnet, the fourth magnet can drive the lens 120 to move in the first direction a.

In some embodiments, the reflective member 132 may be connected to the housing 110 by a sliding connection, an elastic connection, or other common movable connection, so that the reflective member 132 can move relative to the housing 110. For example, in some embodiments, the housing 110 is provided with a slide rail extending along the first direction a, the reflection element 132 is clamped on the slide rail, and the slide rail can guide the movement of the reflection element 132, so that the reflection element 132 can slide along the slide rail under the action of the first driving element 133, that is, the reflection element 132 can move in the first direction a relative to the slide rail. Or in some embodiments, the reflecting member 132 is connected to the housing 110 only by a spring. The movable connection between the lens 120 and the housing 110 can also refer to the connection between the reflector 132 and the housing 110. It should be noted that the connection between the movable structures (such as the reflection element 132 and the lens 120) in the camera module 10 and the housing 110 can be designed in many ways, and common movable connection methods should be considered as being within the scope of the present application, and are not exhaustive here.

Referring back to fig. 3, an embodiment of the present application further provides a camera module 20, where the camera module 20 includes an image sensor 210 and the camera assembly 10 in any of the above embodiments, and the image sensor 210 is disposed at an image side of the camera assembly 10 to receive light converged by the camera assembly 10. The image sensor 210 may be a CCD (Charge Coupled Device) or a CMOS (Complementary Metal Oxide Semiconductor). In some embodiments, the image sensor 210 may be disposed within the receiving cavity 112 of the housing 110. In other embodiments, the image sensor 210 is disposed on the image side of the lens 120 and outside the housing 110, a light exit hole is formed in a region of the housing 110 between the lens 120 and the image sensor 210, and the light adjusted by the lens 120 exits from the housing 110 to the image sensor 210 through the light exit hole. In some embodiments, an infrared filter 220 is further disposed between the lens 120 and the image sensor 210 to filter infrared light. In addition to the above focusing design, in some embodiments, the lens 120 may also be fixedly disposed relative to the image sensor 210, so as to form a fixed-focus camera module.

In the image pickup module 20, the reflective element 132 disposed on the object side of the lens 120 is driven by the first driving element 133 to move along a direction parallel to the optical axis 122 of the lens 120, so as to achieve an anti-shake effect along the optical axis 122. Compared to the rotary optical anti-shake structure, the camera module 20 only needs to reserve a moving space in the direction of the reflective element 132 along the optical axis 122 of the lens 120 to allow the reflective element 132 to move, and does not need to reserve a moving space in the light incident direction of the reflective element 132. Therefore, when the camera module 20 is applied to the electronic device 30 such as a smart phone and a tablet computer, the movement space does not need to be additionally reserved in the light incident direction of the camera module 20 inside the device, thereby being beneficial to reducing the thickness of the device and promoting the miniaturization design of the device. In addition, since the reflective member 132 adopts a movable optical anti-shake design, after the reflective member 132 is moved to compensate for the shake distance, light from each position of the target area can be incident on the lens 120 through an original path before shake, so that the paths before and after the anti-shake adjustment of the incident light beam are overlapped to the maximum extent, thereby improving the imaging consistency in the anti-shake process, maintaining the resolution of the system, and maintaining higher anti-shake compensation accuracy. For the structure using the rotary optical anti-shake function, after the reflection structure rotates by a corresponding angle, the deflection angle of the reflected light reaching the lens 120 is twice as large as the rotation angle, so that the incident light beam has a larger deviation from the path of the incident light to the lens 120 before and after the anti-shake adjustment, which results in the decrease of the resolution of the system.

Referring to fig. 5 and fig. 6, an embodiment of the present application further provides an electronic device 30 applying the camera module 20, where the electronic device 30 includes a fixing member 310, and the camera module 20 is mounted on the fixing member 310. The electronic device 30 may be, but is not limited to, a smart phone, a smart watch, an e-book reader, a vehicle-mounted camera device, a monitoring device, a medical device (such as an endoscope), a tablet computer, a biometric device (such as a fingerprint recognition device or a pupil recognition device), a PDA (Personal Digital Assistant), an unmanned aerial vehicle, and the like. In some embodiments, when the electronic device 30 is a smartphone, the mount 310 of the electronic device 30 may be a bezel. Through adopting above-mentioned module 20 of making a video recording, electronic equipment 30 is when possessing optics anti-shake performance, still is favorable to further reducing the thickness of equipment in the income light direction of subassembly 10 of making a video recording, helps making electronic equipment 30 realize ultra-thin design. Compared with a common optical anti-shake design, the optical anti-shake compensation device has higher anti-shake compensation precision.

In particular, when the lens 120 and the reflector 132 in the camera module 20 can move in mutually perpendicular directions to achieve anti-shake, the electronic device 30 using the camera module 20 can prevent the problem of rotation of the imaging screen during the process of achieving optical anti-shake, thereby improving the imaging sharpness.
