[0002] The present application relates to the technical field of terminal devices, and in particular to a camera module and an electronic device. Background Art

[0003] As users' requirements for shooting on mobile terminal devices become higher and higher, the demand for periscope camera modules is also increasing. However, in existing periscope camera modules, the control accuracy of the anti-shake function is low and the control difficulty is high, which leads to a decrease in the clarity of the camera module shooting, affecting the user experience. Summary of the invention

[0004] The embodiments of the present application provide a camera module and an electronic device for solving the problem that the anti-shake function of a periscope camera module has low control accuracy and high control difficulty, resulting in reduced clarity of the camera module shooting and affecting the user experience.

[0005] To achieve the above objectives, the embodiments of the present application adopt the following technical solutions:

[0006] In a first aspect, a driving motor is provided, which is applied to a periscope camera module, and the driving motor is used to drive a reflective element in the periscope camera module to perform linear motion in one direction. The driving motor includes a housing, a carrier, and a driving component. The carrier is arranged in the housing, the reflective element is fixed on the carrier, and the carrier is used to drive the reflective element to perform linear motion. The driving component is arranged inside the housing, and the driving component is used to drive the carrier to move.

[0007] The driving motor provided in the first aspect of the present application is driven by a driving component to drive the carrier to move, so that the carrier can drive the reflective element to move linearly in one direction, so that the reflective element will not cause displacement in other directions during the movement, thereby helping to improve the accuracy of adjusting the imaging point position of the light on the image sensor, that is, helping to improve the control accuracy of the anti-shake function. In addition, since the displacement is only generated in one direction, the control difficulty can also be reduced. This is conducive to improving the shooting effect of the camera module and improving the user experience.

[0008] In a possible implementation of the first aspect of the present application, the carrier moves along the optical axis of the incident light of the reflective element; or the carrier moves along the optical axis of the outgoing light of the reflective element. In this way, the position of the imaging point of the light on the image sensor along two directions can be adjusted to compensate for the offset of the imaging point.

[0009] In a possible implementation of the first aspect of the present application, the driving motor further includes a movable support member, the movable support member is disposed in the housing, and the carrier is supported on the movable support member. In this structure, the movable support member enables the carrier to move inside the housing, thereby driving the reflective element to move.

[0010] In a possible implementation of the first aspect of the present application, the movable support member includes a spring sheet, and spring sheets are provided at both ends of the carrier in the linear motion direction, the spring sheets are fixed in the shell, and the carrier is supported between the two spring sheets. Under this structure, the carrier is elastically supported inside the shell by the spring sheets, thereby overcoming the deadweight of the carrier and the load (reflective element) to prevent the carrier from tilting inside the shell, which is conducive to improving the reliability of the overall structure.

[0011] In a possible implementation of the first aspect of the present application, the spring sheet includes a first elastic portion, a second elastic portion, and an elastic connection portion, the first elastic portion is fixedly connected to the shell, the second elastic portion is fixedly connected to the carrier, and both ends of the elastic connection portion are fixedly connected to the first elastic portion and the second elastic portion, respectively. Under this structure, when the carrier moves, the elastic connection portion can be stretched, thereby realizing elastic support of the carrier inside the shell.

[0012] In a possible implementation of the first aspect of the present application, the driving component includes a coil and a magnetic part, the coil and the magnetic part are arranged in a shell, one of the coil and the magnetic part is fixed to the outer wall of the carrier, the other of the coil and the magnetic part is fixedly connected to the shell, and the magnetic part is opposite to the coil. In this way, by energizing the coil, an Ampere force can be generated between the coil and the magnetic part, and under the action of the Ampere force, relative movement can occur between the coil and the magnetic part, that is, the carrier can move relative to the shell.

[0013] In a possible implementation of the first aspect of the present application, the driving motor further includes a displacement detection element, which is fixed on the outer wall of the carrier and is opposite to the magnetic member. In this structure, the displacement detection element can detect the displacement stroke of the relative movement between the magnetic member and the carrier, so that the moving distance of the reflective element can be more accurately controlled, which is conducive to further improving the control accuracy of anti-shake.

[0014] In a second aspect, a camera module is provided, which includes a first reflective element, a second reflective element, an image sensor, a first drive motor and a second drive motor. The first reflective element is used to reflect light incident from the outside. The second reflective element is arranged on the light-emitting side of the first reflective element, and the second reflective element is used to reflect the light emitted by the first reflective element. The image sensor has a photosensitive surface, and the photosensitive surface is used to receive the light emitted by the second reflective element. The first drive motor is a drive motor as described in any of the above technical solutions, and the first reflective element is arranged on a carrier of the first drive motor; the first drive motor is used to drive the first reflective element to move in a straight line to compensate for the offset of the imaging point of the light on the photosensitive surface along the first direction. The second drive motor is a drive motor as described in any of the above technical solutions, and the second reflective element is arranged on a carrier of the second drive motor; the second drive motor is used to drive the second reflective element to move in a straight line to compensate for the offset of the imaging point of the light on the photosensitive surface along the second direction. Wherein, the first direction intersects with the second direction, and the first direction and the second direction are both parallel to the photosensitive surface.

[0015] The camera module provided in the second aspect of the present application drives two reflective elements to move respectively through two driving motors, and the two reflective elements can respectively compensate for the offset of the imaging point of the light along the first direction and the second direction. Since the first reflective element and the second reflective element are driven by different driving motors, the movement trajectories of the two are independent of each other, and therefore, they will not interfere with each other, which is conducive to improving the adjustment accuracy. In addition, the first reflective element can compensate for the offset of the imaging point along the first direction, and the second reflective element can compensate for the offset of the imaging point along the second direction. The first direction and the second direction intersect and are parallel to the photosensitive surface. In this way, by controlling and adjusting in two directions separately, the offset in each direction on the upper edge of the photosensitive surface can be covered, which is conducive to improving the control accuracy of anti-shake and reducing the control difficulty, thereby improving the shooting effect of the camera module.

[0016] In a possible implementation of the second aspect of the present application, the camera module further includes an optical lens assembly, the optical lens is arranged on the light-emitting side of the first reflective element, and the optical lens is arranged on the light-entering side of the second reflective element. Under this structure, after the light enters the first reflective element, the offset of the imaging point along the first direction is first adjusted by the first reflective element. Then, the optical lens is used for automatic focusing, and finally, the offset of the imaging point along the second direction is adjusted by the second reflective element, so that shooting can be completed.

[0017] In a possible implementation of the second aspect of the present application, the camera module further includes an optical lens, the optical lens is disposed on the light-emitting side of the second reflective element, and the image sensor is disposed on the light-emitting side of the optical lens. In this structure, after the light enters the first reflective element, the offset of the imaging point along the first direction is first adjusted by the first reflective element, and then the offset of the imaging point along the second direction is adjusted by the second reflective element, and finally the optical lens is used for automatic focusing, so that shooting can be completed.

[0018] In a possible implementation of the second aspect of the present application, the camera module has a light incident surface, the light incident surface is perpendicular to the light sensitive surface, and the first direction is a direction perpendicular to the light incident surface; the second direction is a distribution direction of the first reflecting element and the second reflecting element, and the light sensitive surface and the light incident surface are parallel to the second direction. The first reflecting element has a first reflecting surface, and the second reflecting element has a second reflecting surface. Along the second direction, the first reflecting surface extends in a direction gradually away from the light incident surface, and the second reflecting surface extends in a direction gradually away from the light sensitive surface. That is, the first direction is perpendicular to the second direction, and the light passes through the first reflecting element and the second reflecting element and moves along the direction of its incident light or outgoing light, so that the displacement of the imaging point along the first direction and the second direction can be adjusted respectively.

[0019] In a possible implementation of the second aspect of the present application, the first drive motor is used to drive the first reflective element to perform linear motion along the distribution direction of the first reflective element and the second reflective element. Alternatively, the first drive motor is used to drive the first reflective element to perform linear motion along a direction perpendicular to the light incident surface. Under this structure, when the first reflective element moves along this direction, the light reflected by the first reflective element can be moved along the first direction, so that the final imaging point on the image sensor can be moved along the first direction.

[0020] In a possible implementation of the second aspect of the present application, the second drive motor is used to drive the second reflective element to perform linear motion along the distribution direction of the first reflective element and the second reflective element. Alternatively, the second drive motor is used to drive the second reflective element to perform linear motion along a direction perpendicular to the photosensitive surface. Under this structure, when the second reflective element moves in this direction, the light reflected by the second reflective element can be moved in the second direction, so that the final imaging point on the image sensor can be moved in the second direction.

[0021] In a possible implementation of the second aspect of the present application, the first drive motor includes a first shell, a first carrier, a first coil and a first magnetic member; the first carrier is disposed in the first shell, and the first reflective element is disposed on the first carrier. Along the second direction, first coils are disposed on the outer walls on both sides of the first carrier, and first magnetic members are disposed on the two inner walls of the first shell opposite to the first coil. In this way, by providing two groups of first coils and first magnetic members, it is beneficial to keep the Ampere force on the first carrier balanced, so as to ensure that the first carrier can move in a straight line.

[0022] In a possible implementation of the second aspect of the present application, the first drive motor further includes a first spring sheet, and the first spring sheets are disposed at both ends along the movement direction of the first carrier, the first spring sheets are fixed in the first housing, and the first carrier is supported between the two first spring sheets. The first carrier is elastically supported in the first housing by the two first spring sheets, which is conducive to improving the overall support reliability.

[0023] In a possible implementation of the second aspect of the present application, the second drive motor includes a second shell, a second carrier, a second coil, and a second magnetic member; the second carrier is disposed in the second shell, and the second reflective element is disposed on the second carrier. The second coil and the second magnetic member are disposed on a side of the second carrier away from the first drive motor. In this way, only one set of second coils and second magnetic members are disposed inside the second drive motor, which is conducive to reducing components and reducing costs.

[0024] In a possible implementation of the second aspect of the present application, the second drive motor further includes a second spring sheet, and the second spring sheets are disposed at both ends along the movement direction of the second carrier, the second spring sheets are fixed in the second housing, and the second carrier is supported between the second spring sheets on both sides. The second carrier is elastically supported in the first housing by the second spring sheets on both sides, which is conducive to improving the overall support reliability.

The camera module is the camera module described in any of the above technical solutions, and the camera module is arranged in the housing.

[0026] The electronic device provided in the third aspect of the present application, because it includes the camera module described in any of the above technical solutions, can solve the same technical problems and achieve the same technical effects. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0052] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0053] In the following, the terms "first", "second", etc. are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first", "second", etc. may explicitly or implicitly include one or more of the features.

[0054] In addition, in the present application, directional terms such as "upper" and "lower" are defined relative to the orientation of the components in the drawings. It should be understood that these directional terms are relative concepts. They are used for relative description and clarification, and they can change accordingly according to the changes in the orientation of the components in the drawings.

[0055] In the present application, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0056] The embodiment of the present application provides an electronic device. Specifically, the electronic device may be a portable electronic device or other types of electronic devices. For example, the electronic device may be a mobile phone, a tablet computer, a laptop computer, a personal digital assistant (PDA), a monitor, a camera, a personal computer, a notebook computer, a wearable device, etc. For the convenience of explanation, the following examples are all taken as an example of the electronic device being a mobile phone.

[0057] See also Figure 1 and Figure 2 , Figure 1 This is a structural diagram of an electronic device 01 provided in an embodiment of the present application. Figure 2 The exploded view of the electronic device 01 provided in the embodiment of the present application. As can be seen from the above, in the present embodiment, the electronic device 01 is a mobile phone, and the electronic device 01 can be in an approximately rectangular plate-shaped structure. The electronic device 01 can include a display module 10, a housing 20, a mainboard 30 and a camera module 40.

[0058] For the convenience of the following description, an XYZ coordinate system is established, and the width direction of the single device is defined as the X-axis direction, the length direction of the electronic device 01 is defined as the Y-axis direction, and the thickness direction of the electronic device 01 is defined as the Z-axis direction. It can be understood that the coordinate system of the electronic device 01 can be flexibly set according to actual needs, and this application only gives an example, which cannot be considered as a special limitation of this application. Figure 1 and Figure 2 Only some components of the electronic device 01 are schematically shown, and the actual shapes, sizes, positions and structures of these components are not subject to the present invention. Figure 1 and Figure 2 restrictions.

[0059] The above-mentioned display module 10 is used to display images, videos, etc. The display module 10 may include a transparent cover plate 11 and a display screen 12 (English name: panel 1, also called a display panel), and the transparent cover plate 11 and the display screen 12 are stacked. The material of the transparent cover plate 11 includes but is not limited to glass. For example, the transparent cover plate 11 can adopt an ordinary transparent cover plate 11, which is used to protect the display screen 12 to prevent the display screen 12 from being damaged by external force, and can play a dust-proof role. Alternatively, the transparent cover plate 11 can also adopt a transparent cover plate 11 with a touch function, so that the electronic device 01 has a touch function, which makes it more convenient for users to use. Therefore, the present application does not specifically limit the specific material of the transparent cover plate 11.

[0060] In addition, the display screen 12 may be a flexible display screen 12 or a rigid display screen 12. For example, the display screen 12 may be an organic light-emitting diode (OLED) display screen 12, an active-matrix organic light-emitting diode or an active-matrix organic light-emitting diode (AMOLED) display screen 12, a mini light-emitting diode (MID) display screen 12, a micro organic light-emitting diode (MID) display screen 12, a micro organic light-emitting diode (MID) display screen 12, a quantum dot light-emitting diode (QLED) display screen 12, or a liquid crystal display screen 12 (LCD).

[0061] The housing 20 is used to protect the electronic components inside the electronic device 01. The housing 20 may include a back cover 21 and a frame 22. The back cover 21 is located on the side of the display screen 12 away from the light-transmitting cover plate 11, and is stacked with the light-transmitting cover plate 11 and the display screen 12. The frame 22 is located between the light-transmitting cover plate 11 and the back cover 21. The frame 22 is fixed to the back cover 21. For example, the frame 22 may be fixed to the back cover 21 by bonding, threading, welding, snapping, etc.; or, the frame 22 may also be an integrally formed structure with the back cover 21, that is, the frame 22 and the back cover 21 form a structural component as a whole. The light-transmitting cover plate 11 may be fixed to the frame 22 by gluing, so that the light-transmitting cover plate 11, the back cover 21 and the frame 22 enclose a receiving cavity inside the electronic device 01, and the above-mentioned electronic components are all arranged in the receiving cavity.

[0062] In some embodiments, the housing 20 may further include a middle plate 23, which is disposed in the accommodating cavity, and is located on the side of the display screen 12 away from the light-transmitting cover plate 11. The middle plate 23 is fixedly connected to the frame 22 to form the middle frame of the electronic device 01. For example, the middle plate 23 and the frame 22 may be fixedly connected by gluing, threading, welding, snapping, etc.; or, the middle plate 23 and the frame 22 may also be an integrally formed structure, that is, the middle plate 23 and the frame 22 form a structural component as a whole. The middle plate 23 divides the accommodating cavity into two independent spaces, one of which is located between the light-transmitting cover plate 11 and the middle plate 23, and the display screen 12 is located in the space. The other space is located between the middle plate 23 and the back cover 21, and the main board 30 and the camera module 40 are located in the space.

[0063] The mainboard 30 is used to set the electronic devices inside the electronic device 01 and realize the electrical connection between the electronic devices. The mainboard 30 can be fixed on the middle plate 23 by gluing, threading, welding, clamping, etc. Therefore, the present application does not specifically limit the fixing method of the mainboard 30.

[0064] In addition, the above-mentioned electronic devices may be a control chip (such as a system on chip, SOC), a graphics control chip (graphics processing unit, GPU), a universal storage (universal flash storage, UFS) and the above-mentioned camera module 40, etc.

[0065] The camera module 40 is used to realize the shooting of videos or images. The camera module 40 includes but is not limited to a main camera, a wide-angle camera, and a telephoto camera. Specifically, the camera module 40 may include an optical lens 41 and a flexible connection structure, and the optical lens 41 is electrically connected to the mainboard 30 through the flexible connection structure. For example, the flexible connection structure may include an FPC board 42 (flexible printed circuit) or a structure formed by weaving a wire and a flexible material, which is not particularly limited here.

[0066] Also, see Figure 3 , Figure 3 for Figure 1 and Figure 2The structural diagram of the camera module 40 is provided, and a driving device is also integrated in the camera module 40, and the driving device is used to realize the automatic focusing (Automatic Focusing, AF) function of the optical lens 41. In some embodiments, the driving device can be a driving motor 45, the camera module 40 is arranged on the main board 30, and the axis of the optical lens 41 is perpendicular to the back cover 21 (that is, arranged along the Z axis direction), and the driving device is used to drive the lens in the optical lens 41 to move along its axis (that is, move along the Z axis direction) to realize automatic focusing, that is, the structural form of the camera module 40 is upright.

[0067] For the upright camera module 40, to improve the shooting effect at a longer distance, it is necessary to increase the moving range of the optical lens 41 along its axis to achieve a larger zoom ratio, thereby improving the shooting effect at a longer distance. However, increasing the moving range of the lens means increasing the size of the camera module 40 along the axis of the optical lens 41 (i.e., the size along the Z-axis direction). Therefore, under the premise that the thickness of the electronic device 01 remains unchanged, the volume of the camera module 40 protruding from the back cover 21 will increase, affecting the overall appearance.

[0068] Based on this, in order to improve the aesthetics of the electronic device 01, a periscope camera module 40 has emerged. Figure 4 , Figure 4 Schematic diagram of the optical path propagation of the periscope camera module 40 provided in the embodiment of the present application. The periscope camera module 40 also includes a reflective element 43, such as an optical prism, which is arranged on the light incident side of the optical lens 41, and the axis of the optical lens 41 is arranged in a direction parallel to the back cover 21 (that is, the axis of the optical lens 41 is parallel to the XY plane). The external light first enters the reflective element 43, and then enters the optical lens 41 after being reflected by the reflective surface 431 of the reflective element 43. In this way, since the axis of the optical lens 41 is parallel to the back cover 21, increasing the movement range of the lens of the optical lens 41 along its axis will not cause the volume of the camera module 40 protruding from the back cover 21 to increase, thereby achieving a larger zoom ratio and improving the long-distance shooting effect while maintaining the overall beauty of the electronic device 01.

[0069] For example, the optical lens 41 of the periscope camera module 40 is arranged along the Y-axis direction. The camera module 40 has a light incident surface 40a, and the light incident surface 40a is parallel to the XY plane. The camera module 40 at least includes a reflective element 43, an optical lens 41, and an image sensor 44. The light L( Figure 4The light L is incident on the reflective element 43 from the incident surface 40a along the Z-axis direction, and is reflected by the reflective surface 431 of the reflective element 43. The transmission path of the light L turns and propagates along the Y-axis direction, and is incident on the optical lens 41. After the optical lens 41 is automatically focused, an image is formed on the image sensor 44, and the shooting is completed. It can be seen that the focusing limit distance of the optical lens 41 under the automatic focusing function does not affect the thickness dimension of the electronic device 01 in the Z-axis direction. Therefore, the focusing limit distance can be designed to be larger, that is, the moving range of the lens of the optical lens 41 is increased.

[0070] However, the improvement of shooting effect does not only depend on the above-mentioned zoom ratio. For example, shaking during shooting will also cause the captured image to be blurred. Therefore, the function of optical image stabilization (OIS) is added to the camera module 40. That is, during the shooting process, when the electronic device 01 shakes, the optical components in the camera module 40 are driven by the above-mentioned drive motor 45 to move according to the direction of the shaking to compensate for the offset of the imaging point of the light on the image sensor 44 caused by the shaking, so that the light can be clearly imaged on the image sensor 44, which is conducive to improving the shooting effect.

[0071] Among them, see Figure 5 , Figure 5 Schematic diagram of the photosensitive surface 44a of the image sensor 44 provided in an embodiment of the present application. The offset direction of the imaging point of the light on the image sensor 44 can be divided into two directions, for example, a first direction (i.e., direction a in the figure) and a second direction (i.e., direction b in the figure) perpendicular to each other, and both directions a and b are parallel to the photosensitive surface 44a of the image sensor 44. Therefore, by compensating for the offset in the two directions, clear imaging of the light on the image sensor 44 can be achieved.

[0072] For example, please refer to Figure 4 and Figure 5 The reflective element 43 of the camera module 40 can compensate for the offset of the imaging point of the light on the image sensor 44 along the a direction and the b direction by moving in two directions. In addition, the optical lens 41 can automatically zoom, thereby improving the shooting effect of the camera module 40.

[0073] Alternatively, the anti-shake function of the camera module 40 can also be achieved by the movement of other optical elements. For example, the reflective element 43 can be moved in one direction to compensate for the offset of the imaging point of the light on the image sensor 44 along the above-mentioned direction a, and the optical lens 41 can be moved in another direction to compensate for the offset of the imaging point of the light on the image sensor 44 along the direction b.

[0074] Alternatively, the reflective element 43 is fixed, and the optical lens 41 moves in two directions respectively to compensate for the offset of the imaging point of the light on the image sensor 44 along the above-mentioned directions a and b; and the optical lens 41 can achieve automatic zoom. Alternatively, the reflective element 43 is fixed, and the optical lens 41 achieves automatic zoom, and the image sensor 44 can move in two directions respectively to compensate for the offset of the imaging point of the light on the image sensor 44 along the above-mentioned directions a and b.

[0075] Based on this, the camera module 40 in which the motion of the reflective element 43 is used to realize the anti-shake function is taken as an example. Figure 6 , Figure 6 A schematic diagram of an anti-shake camera module 40 provided in the related art. In the related art, the reflective element 43 is controlled to rotate around the midline of the reflective surface 431 parallel to the X-axis direction (such as the direction A in the figure) to adjust the imaging point of the light on the image sensor 44 along the Figure 5 Furthermore, the reflective element 43 can rotate around the intersection of the reflective surface 431 and the YZ plane (in the direction B in the figure) under the control of the driving motor 45 to adjust the imaging point of the light on the image sensor 44 along the direction of Figure 5 The displacement in the b direction is shown in FIG. 4 , thereby compensating for the offset of the imaging point of the light caused by the jitter.

[0076] However, see Figure 7 , Figure 7 for Figure 6 A schematic diagram of the relative position of the reflective element 43 of the camera module 40 rotating along the A direction is provided. During the rotation of the reflective element 43, for example, when the reflective element 43 rotates around the midline on the reflective surface 431 parallel to the X-axis direction (rotates along the A direction), the reflective element 43 rotates from the position shown by the solid line in the figure to the position shown by the dotted line, and a reflection point located on the reflective surface 431 of the reflective element 43 moves from the C1 position to the C2 position. In this process, the reflection point moves a distance D1 along the Z axis and a distance D2 along the Y axis, that is, the reflection point has two linear displacements during the rotation process.

[0077] In the process of adjusting the anti-shake of the camera module 40, only the reflection point needs to be moved along the Z-axis direction to adjust the imaging point of the light on the image sensor 44 along the a-direction. Therefore, the displacement of the reflection point along the Y-axis direction will reduce the adjustment accuracy of the anti-shake and increase the control difficulty.

[0078] Furthermore, in some anti-shake scenarios, the reflective element 43 is Figure 6 While rotating in the direction A shown, it will also Figure 6The reflective element 43 rotates in two directions (i.e., directions A and B in the figure), which will cause the displacement direction of any reflection point on the reflective surface 431 to further increase, thus further reducing the accuracy of the anti-shake adjustment and further increasing the control difficulty, which is not conducive to improving the shooting effect.

[0079] To solve the above technical problems, please refer to Figure 8 and Fig. 9 , Figure 8 A structural diagram of a camera module 40 provided in an embodiment of the present application, Fig. 9 for Figure 8 A schematic diagram of light path propagation of a camera module 40 is provided. The camera module 40 includes a first reflective element 43a, a second reflective element 43b, a first drive motor 45a, a second drive motor 45b, an optical lens 41 and an image sensor 44.

[0080] The first reflective element 43a is used to reflect the incident light L from the outside, and the first reflective element 43a is arranged on the first driving motor 45a, and the first driving motor 45a is used to drive the first reflective element 43a to move in a straight line to compensate for the offset of the imaging point of the light on the photosensitive surface 44a of the image sensor 44 along the first direction. The second reflective element 43b is arranged on the light-emitting side of the first reflective element 43a, and the second reflective element 43b is used to reflect the light emitted by the first reflective element 43a, and the second reflective element 43b is arranged on the second driving motor 45b, and the second driving motor 45b is used to drive the second reflective element 43b to move in a straight line to compensate for the offset of the imaging point of the light on the photosensitive surface 44a of the image sensor 44 along the second direction. The first direction and the second direction intersect, and the first direction and the second direction are both parallel to the photosensitive surface 44a of the image sensor 44.

[0081] For some examples, see Figure 8 and Fig. 9 The above-mentioned optical lens 41 can be arranged between the light-emitting side of the first reflecting element 43a and the light-incoming side of the second reflecting element 43b, that is, the light is reflected by the first reflecting element 43a, and then, is incident on the optical lens 41. The light emitted by the optical lens 41 is then reflected by the second reflecting element 43b, and finally forms an image on the photosensitive surface 44a of the image sensor 44.

[0082] Alternatively, see Fig.10 and Fig.11 , Fig.10 This is a structural diagram of another camera module 40 provided in an embodiment of the present application. Fig.11 for Fig.10A schematic diagram of the optical path propagation of the camera module 40 is provided. The optical lens 41 can also be arranged between the light-emitting side of the second reflective element 43b and the image sensor 44, that is, the light passes through the first reflective element 43a and the second reflective element 43b in sequence, and then enters the optical lens 41, and finally forms an image on the photosensitive surface 44a of the image sensor 44.

[0083] Furthermore, the optical lens 41 may be a fixed-focus lens or a zoom lens, and therefore, the present application does not specifically limit the specific location and type of the optical lens 41. The following description is based on an example in which the optical lens 41 is disposed between the light-emitting side of the first reflective element 43a and the light-entering side of the second reflective element 43b.

[0084] For example, see Fig.12 , Fig.12 for Figure 8 The structure diagram of the first reflective element 43a, the second reflective element 43b and the image sensor 44 of the camera module 40 is provided. The light incident surface 40a of the camera module 40 can be perpendicular to the light sensitive surface 44a of the image sensor 44. Figure 5 The a direction in the figure is perpendicular to the light incident surface 40a (i.e., the Z-axis direction), and the second direction (b direction in the figure, i.e., Figure 5 The direction b shown in the figure is the distribution direction of the first reflective element 43a and the second reflective element 43b (ie, the Y-axis direction), and the light incident surface 40a and the light sensitive surface 44a are parallel to the second direction. That is, the first direction and the second direction are perpendicular to each other.

[0085] In the camera module 40, the external light L is incident on the first reflective element 43a through the light incident surface 40a along the Z-axis direction. The light L is reflected by the first reflective element 43a, and the propagation path of the light L turns and propagates along the Y-axis direction. Then, the light L is incident on the optical lens 41 along the Y-axis direction, and after the optical lens 41 automatically focuses, it is incident on the second reflective element 43b. The light L is emitted by the second emitting element, and the propagation path of the light L turns here and propagates along the X-axis direction, and forms an image on the photosensitive surface 44a of the image sensor 44, thereby completing the shooting.

[0086] Furthermore, during the optical image stabilization adjustment process, the camera module 40 can achieve optical image stabilization by respectively compensating the offset of the imaging point along the first direction and the second direction. The light L may include three parts, wherein the part propagating along the Z axis is light L1, the part propagating along the Y axis direction after being reflected by the first reflective element 43a is light L2, and the part propagating along the X axis after being reflected by the second reflective element 43b is light L3.

[0087] The first driving motor 45a can drive the first reflecting element 43a to move along the first direction (ie, the Z-axis direction) to compensate for the offset of the imaging point along the first direction. Fig.13 Combined with Fig.12 As shown, Fig.13 Schematic diagram of the first reflective element 43a changing the position of the light L2 during the movement process provided in the embodiment of the present application. When the first reflective element 43a moves along the first direction (such as Fig.13 4 (shown as a first reflecting element 43a in solid line and a first reflecting element 43a in dotted line), the reflection point of the light L1 on the reflecting surface 431 of the first reflecting element 43a can be moved along the first direction, so that the position of the light L2 reflected by the first reflecting element 43a along the first direction can be adjusted (as shown in FIG. Fig.13 Then, after the light L2 is focused by the optical lens 41 and reflected by the second reflective element 43b, it forms an image on the photosensitive surface 44a of the image sensor 44. At this time, the positions of the light L2 and the light L3 along the Z-axis direction are the same, that is, the displacement of the imaging point along the first direction can be adjusted, thereby compensating for the displacement of the imaging point along the first direction (i.e. Fig.12 The offset in the a direction).

[0088] At the same time, since the second reflective element 43b is used to reflect the propagation path of the light L from the Y-axis direction to the X-axis direction, the second reflective element 43b will not affect the displacement of the light L along the Z-axis direction.

[0089] Alternatively, see Fig.14 , Fig.14 A schematic diagram of changing the position of the light L2 when the first reflective element 43a provided in the embodiment of the present application moves in another direction. The first reflective element 43a can also move in the second direction (i.e., the Y-axis direction), and can also make the reflection point of the light L1 on the first reflective surface 431 move in the first direction, that is, it can adjust the position of the light L2 after reflection in the first direction. Its optical propagation path is the same as the above example, so it will not be described repeatedly.

[0090] Also, see Fig.15 Combined with Fig.12 As shown, Fig.15 Schematic diagram of the second reflective element 43b provided in the embodiment of the present application changing the position of the light L3 during movement. The second reflective element 43b can move along the second direction (Y-axis direction) to compensate for the image point moving along the second direction (i.e. Fig.12 Specifically, when the second driving motor 45b drives the second reflecting element 43b to move along the second direction (such as Fig.15The second reflecting element 43b shown in the solid line and the second reflecting element 43b shown in the dotted line can make the reflection point of the light L2 on the second reflecting surface 431 of the second reflecting element 43b move along the second direction, so that the position of the light L3 reflected by the second reflecting element 43b along the second direction can be adjusted (as shown by the solid line L3 and the dotted line L3 in the figure), and then the light is imaged on the image sensor 44, that is, the displacement of the imaging point on the image sensor 44 along the second direction can be adjusted, so as to compensate for the offset of the imaging point along the second direction.

[0091] Alternatively, see Fig.16 , Fig.16 Schematic diagram of changing the position of the light L3 when the second reflecting element 43b provided in the embodiment of the present application moves in another direction. The second reflecting element 43b can also move in the X-axis direction, that is, in a direction perpendicular to the photosensitive surface 44a of the image sensor 44, and can also make the reflection point of the light L2 on the second reflecting surface 431 move in the second direction, that is, can adjust the position of the light L3 after reflection in the second direction. Its optical path propagation path is the same as the above example, so it will not be described repeatedly.

[0092] Based on this, the camera module 40 provided by the present application drives the first reflective element 43a to move in a straight line by the first driving motor 45a to compensate for the offset of the imaging point of the light on the photosensitive surface 44a of the image sensor 44 along the first direction. Then, the second reflective element 43b is driven by the second driving motor 45b to move in a straight line to compensate for the offset of the imaging point of the light on the photosensitive surface 44a of the image sensor 44 along the second direction.

[0093] In this way, the first reflecting element 43a and the second reflecting element 43b both move in a straight line, that is, during the anti-shake adjustment process, any reflection point on the reflecting surface 431 of the first reflecting element 43a and the second reflecting element 43b can only produce a linear displacement in one direction and will not produce displacement in other directions. Therefore, it is helpful to improve the adjustment accuracy.

[0094] Furthermore, the first reflective element 43a and the second reflective element 43b are driven by the first driving motor 45a and the second driving motor 45b respectively, that is, the first reflective element 43a and the second reflective element 43b move relatively independently and do not affect each other, which is conducive to further improving the adjustment accuracy and reducing the control difficulty.

[0095] The specific structures of the camera module 40 and the first drive motor 45a and the second drive motor 45b therein are described in detail below.

[0096] The first drive motor 45a and the second drive motor 45b can be drive motors 45 with the same driving principle, and the difference between the two is that the movement directions of the corresponding reflective elements 43 (i.e., the first reflective element 43a and the second reflective element 43b) are different. The drive motor 45 is applied to the periscope camera module 40 and is used to drive the reflective element 43 in the camera module 40 to move linearly in one direction.

[0097] Specifically, see Fig.17 , Fig.17 Exploded view of the drive motor 45 provided in the embodiment of the present application. The drive motor 45 may include a housing 100, a carrier 200, and a drive assembly. The carrier 200 is disposed inside the housing 100, and the reflective element 43 of the camera module 40 is fixed on the carrier 200, and the carrier 200 is used to drive the reflective element 43 to perform linear motion. The drive assembly is disposed inside the housing, and the drive assembly is used to drive the carrier to move.

[0098] In some possible examples, the above-mentioned driving component may include a coil 300 and a magnetic part 400, both of which are arranged in the shell 100, one of the coil 300 and the magnetic part 400 is fixed on the outer wall of the carrier 200, and the other of the coil 300 and the magnetic part 400 is fixedly connected to the shell 100, and the magnetic part 400 is opposite to the coil 300.

[0099] For example, the coil 300 can be fixed on the outer wall of the carrier, and the magnetic member 400 can be fixed on the inner wall of the housing 100. When the coil 300 in the driving motor 45 is energized, under the action of the magnetic field of the magnetic member 400, a force (Ampere force) can be generated between the coil 300 and the magnetic member 400, thereby driving the carrier 200 and the reflective element 43 disposed on the carrier 200 to move in a certain direction. The reflective element 43 moves in a straight line to achieve the optical image stabilization function of the camera module 40.

[0100] In some other possible examples, the driving assembly may also use shape memory alloy (SMA), that is, use an SMA type driving motor 45. The SMA type driving motor 45 has the advantage of being small in size, and therefore is conducive to reducing the volume of the camera module 40. Its specific working principle is a mature prior art and is not described here.

[0101] It is understandable that the drive components of the drive motor 45 provided in the embodiment of the present application include but are not limited to the above two types, and any other form of drive components can be applied to the drive motor 45 provided in the embodiment of the present application. The embodiment of the present application is described below by taking the drive components as the coil 300 and the magnetic member 400 as an example.

[0102] Furthermore, it can be known from the above that the carrier 200 can move along the optical axis of the incident light of the reflective element 43 disposed on the carrier 200 , or move along the optical axis of the outgoing light of the reflective element 43 .

[0103] In some embodiments, the carrier 200 may be provided with a receiving space 201, and the reflective element 43 may be fixed in the receiving space 201. For example, the reflective element 43 may be fixed in the receiving space 201 by bonding, clamping, etc. In addition, along the light incident direction and the light emitting direction of the reflective element 43, the carrier 200 is provided with an opening structure connected with the receiving space 201, so that light can extend into the receiving space 201 and be emitted out of the receiving space 201 after being reflected by the reflective element 43.

[0104] In addition, the coil 300 and the magnetic member 400 (for example, a magnet, a magnet, etc.) disposed outside the carrier 200 may be symmetrically disposed with two sets of coils 300 and magnetic members 400 on both sides of the carrier 200 along its moving direction, so as to balance the forces generated on both sides of the carrier 200. Alternatively, only one set of coils 300 and magnetic members 400 may be disposed, which is beneficial to reducing the overall cost. Therefore, this application does not make any special limitation on this.

[0105] In addition, in order to support the carrier 200, the driving motor 45 may further include a movable support member, which is disposed inside the housing 100 and on which the carrier 200 is supported. Fig.18 , Fig.18 A structural diagram of a carrier 200 and a movable support member of a driving motor 45 provided in an embodiment of the present application. The movable support member may include a spring sheet 500, which is disposed on both sides of the moving direction of the carrier 200, the spring sheet 500 being fixed inside the housing 100, and the carrier 200 being supported between the spring sheets 500. In this way, the spring sheets 500 can form an effective elastic support for the carrier 200, so that the carrier 200 can move along the distribution direction of the two spring sheets 500.

[0106] The elastic sheet 500 may include a first elastic portion 510, a second elastic portion 520 and an elastic connection portion 530, wherein the first elastic portion 510 is fixedly connected to the housing 100, the second elastic portion 520 is fixedly connected to the carrier 200, and both ends of the elastic connection portion 530 are respectively fixedly connected to the first elastic portion 510 and the second elastic portion 520. In this way, the two elastic sheets 500 can prevent the carrier 200 from tilting relative to the housing 100 under the action of its own weight and load (including the weight of the reflective element 43), thereby improving the support stability of the carrier 200 in the housing 100.

[0107] In some possible embodiments, the movable support member may also be a coil spring or a ball structure, etc. Therefore, the present application does not specifically limit the specific structure of the movable support member.

[0108] In another example, in order to detect the displacement of the carrier 200 and the reflective element 43, the current passing through the coil 300 can be controlled to control the moving distance of the carrier 200 and the reflective element 43. Alternatively, see Fig.19 , Fig.19 This is a structural diagram of another carrier 200 and a magnetic member 400 provided in an embodiment of the present application. A displacement detection element 600 for detecting displacement, such as a Hall sensor, a displacement sensor, etc., may be disposed on the outer wall of the carrier 200 .

[0109] Taking the displacement detection element 600 as a Hall sensor as an example, the displacement detection element 600 is arranged opposite to the magnetic element 400, and the displacement detection element 600 can detect the displacement of the relative movement between the magnetic element 400 and the carrier 200, thereby accurately measuring the moving distance of the carrier 200 and the reflective element 43. This is conducive to further improving the anti-shake adjustment accuracy.

[0110] Since the camera module 40 is provided with two reflective elements 43 and two drive motors 45, namely the first reflective element 43a and the second reflective element 43b, and driven by the first drive motor 45a and the second drive motor 45b respectively. Furthermore, since the first reflective element 43a and the second reflective element 43b are arranged in different positions and reflective directions of light. Therefore, the first reflective element 43a and the second reflective element 43b have different movement directions in optical image stabilization, so that the arrangement positions of the various elements inside the first drive motor 45a and the second drive motor 45b will be different.

[0111] Based on this, the specific configuration structure of the first driving motor 45 a and the second driving motor 45 b in the camera module 40 is described below by way of example.

[0112] In some embodiments, see Fig. 20 , Fig. 20 An exploded view of the first driving motor 45a of the camera module 40 provided in an embodiment of the present application, Fig.21 for Fig. 20An assembly diagram of a first driving motor 45a (the first upper cover 130a is not shown in the figure) is provided. The above-mentioned first driving motor 45a may include a first shell 100a, a first carrier 200a, a first coil 300a, a first magnetic member 400a and a first elastic piece 500a. The first carrier 200a is elastically supported in the first shell 100a by the first elastic piece 500a, and the first reflecting element 43a is arranged in the accommodating space 201 on the first carrier 200a. Along the above-mentioned X-axis direction, the first coil 300a is arranged on both sides of the first carrier 200a, and the first magnetic member 400a is arranged on the two inner walls opposite to the two first coils 300a in the first shell 100a.

[0113] In order to facilitate the light L to be captured by the light incident surface 40a of the camera module 40 and to be emitted after being reflected by the first reflective element 43a, an opening structure connected to the accommodating space 201 is provided on the wall plate of the first carrier 200a perpendicular to the first direction (i.e., the Z-axis direction) and close to the light incident surface 40a, and on the wall plate perpendicular to the second direction (i.e., the Y-axis direction) and close to the optical lens 41, so that the light incident on the first reflective element 43a along the Z-axis direction can be emitted along the Y direction and incident on the optical lens 41 along the Y direction.

[0114] It is understandable that the opening structure provided on the first carrier 200a can provide a gap of appropriate size on the corresponding wall plate so that light can enter and exit normally. Alternatively, the corresponding two wall plates can be eliminated on the first carrier 200a. For example, the accommodation space 201 in the first carrier 200a is a space formed by four inner walls connected and enclosed, and the remaining two adjacent inner walls form an opening structure for light to enter and exit. Therefore, the present application does not make any special limitation on this.

[0115] To facilitate the fixation of the first coil 300a, the first carrier 200a may be provided with a first protrusion 210a on its outer wall, and the first coil 300a may be wound around the corresponding first protrusion 210a, thereby improving the support reliability of the overall structure.

[0116] In addition, the first spring piece 500a may be an annular structure. For example, the first elastic portion 510 of the first spring piece 500a and the second elastic portion 520 of the first spring piece 500a both form an annular structure. In this example, a substantially square ring is used as an example, and the first elastic portion 510 of the first spring piece 500a is sleeved on the second elastic portion 520 of the first spring piece 500a (e.g. Fig.18The first elastic part 510 of the first elastic sheet 500a is fixedly connected to the first shell 100a, and the second elastic part 520 of the first elastic sheet 500a is fixedly connected to the first carrier 200a. The two can be fixedly connected via a plurality of elastic connecting parts 530, so that the first carrier 200a can be elastically supported inside the shell 100.

[0117] To enable the first carrier 200a to move along the first direction, please continue to refer to Fig. 20 and Fig.21 , the first shell 100a may be provided with a first boss 110a on the inner wall corresponding to the two first spring sheets 500a, and the first carrier 200a may be provided with a second boss 220a on the two corresponding outer walls. The first elastic parts 510 of the two first spring sheets 500a are fixed on the corresponding first boss 110a, and the second elastic parts 520 of the two first spring sheets 500a are fixed on the corresponding second boss 220a, so that when the first spring sheets 500a are in a free state, the first elastic parts 510, the second elastic parts 520 and the elastic connection parts 530 of the first spring sheets 500a are in the same plane, and when the first carrier 200a moves, the elastic connection parts 530 of the first spring sheets 500a will be stretched, which is conducive to protecting the first spring sheets 500a intact, thereby extending the service life.

[0118] At the same time, it is also possible to avoid the first carrier 200a from abutting against the inner wall of the first shell 100a along the first direction (i.e., the Z-axis direction), so that the first carrier 200a can move along the first direction. It is understandable that the first driving motor 45a can also drive the first carrier 200a and the first reflecting element 43a to move along the second direction. Therefore, when the first carrier 200a and the first reflecting element 43a move along the second direction, the two first elastic sheets 500a are arranged on both sides of the first carrier 200a along the second direction, and no repeated description is given for this.

[0119] To facilitate the assembly of the first drive motor 45a, please continue to refer to Fig. 20 and Fig.21 , the first shell 100a may include a first base 120a and a first upper cover 130a, the first upper cover 130a is snapped onto the first base 120a, and a cavity for accommodating the above components is formed therebetween, thereby facilitating the assembly of the overall structure. In some examples, one of the two first bosses 110a is disposed on the first upper cover 130a, and the other is disposed on the first base 120a. Furthermore, one first boss 110a may be fixed to the inner wall of the first upper cover 130a by gluing, snapping, or the like, and the other first boss 110a may form an integrally formed structure with the first base 120a. Therefore, the present application does not make any special limitation on this.

[0120] On this basis, see Fig. 22 and Fig.23 , Fig. 22 An exploded view of the second driving motor 45b of the camera module 40 provided in an embodiment of the present application, Fig.23 for Fig. 22 An assembly diagram of a second driving motor 45b (the second upper cover 130b is not shown) is provided.

[0121] The second drive motor 45b may include a second shell 100b, a second carrier 200b, a second coil 300b, a second magnetic member 400b and a second elastic sheet 500b. The second carrier 200b is elastically supported inside the second shell 100b by the second elastic sheet 500b, and the second reflective element 43b is disposed in the accommodating space 201 of the second carrier 200b. Along the second direction (i.e., the Y-axis direction), the second coil 300b and the second magnetic member 400b are disposed on the side of the second carrier 200b away from the first drive motor 45a, i.e., only one second coil 300b and one second magnetic member 400b are disposed in the second drive motor 45b.

[0122] Since the basic structure of the second drive motor 45b is the same as that of the first drive motor 45a, the difference between the two is only in the connection of the various components and some structures. Therefore, the same parts are not described repeatedly. For example, a second protrusion 210b is provided on the outer wall of the second carrier 200b, and the second coil 300b is wound around the second protrusion 210b.

[0123] The light that needs to be reflected by the second reflective element 43b enters the second reflective element 43b from the Y direction, is emitted from the X-axis direction, and finally forms an image on the image sensor 44. Therefore, the opening structure on the second carrier 200b is arranged on the wall plate perpendicular to the Y-axis direction and close to the first driving motor 45a, and on the wall plate perpendicular to the X-axis direction and close to the image sensor 44, so that the light can enter the accommodating space 201 of the second carrier 200b and be reflected by the second reflective element 43b.

[0124] In addition, the second spring piece 500b may be distributed in a different manner and have a different structure than the first spring piece 500a. Fig. 22 and Fig.23 , the second elastic fragments 500b may be provided in two groups, and the two groups of second elastic fragments 500b are provided on both sides of the second carrier 200b along the Y-axis direction. Each group of second elastic fragments 500b includes two second elastic fragments 500b, and the two second elastic fragments 500b in each group of second elastic fragments 500b are distributed on both sides of the second carrier 200b along the X-axis direction. That is, four second elastic fragments 500b are provided between the second carrier 200b and the second shell 100b.

[0125] Furthermore, each second elastic piece 500b includes the above-mentioned first elastic part 510, second elastic part 520 and elastic connecting part 530, and the first elastic part 510 and second elastic part 520 of the second elastic piece 500b can adopt a plate-like structure, and do not need to adopt a ring structure. The first elastic part 510 of each second elastic piece 500b is fixedly connected to the second shell 100b, and the second elastic part 520 of each second elastic piece 500b is fixedly connected to the second carrier 200b, and the two are fixedly connected through a plurality of elastic connecting parts 530, so that the second carrier 200b is elastically supported inside the second shell 100b. Furthermore, the plane where each second elastic piece 500b is located is parallel to the XZ plane, so that the second carrier 200b can move along the Y-axis direction.

[0126] In some embodiments, in the above two groups of second elastic sheets 500b, two second elastic sheets 500b in one group of second elastic sheets 500b may be connected to form an integral structure, and two second elastic sheets 500b in the other group of second elastic sheets 500b may be two independent components. Therefore, this application does not make any special limitation on this.

[0127] To facilitate the movement of the second carrier 200b along the Y-axis direction, please continue to refer to Fig. 22 and Fig.23 The second housing 100b may be provided with a third boss 110b inside, and the second carrier 200b may be provided with a third boss 110b on both sides along the Y-axis direction corresponding to each second elastic sheet 500b, the first elastic portion 510 of each second elastic sheet 500b is fixed to the corresponding third boss 110b, and the second elastic portion 520 of each second elastic sheet 500b is fixedly connected to the second carrier 200b. The specific function is the same as that of the first elastic sheet 500a, so it will not be described again here.

[0128] It can be understood that the second driving motor 45b can also drive the second carrier 200b and the second reflective element 43b to move along the X-axis direction. Therefore, when the second carrier 200b and the second reflective element 43b move along the X-axis direction, the two groups of second elastic sheets 500b are distributed on both sides of the second carrier 200b along the X-axis direction, and the two second elastic sheets 500b in each group of second elastic sheets 500b are distributed on both sides of the second carrier 200b along the Y-axis direction. In addition, the plane formed by each second elastic sheet 500b is parallel to the YZ plane, so that the second carrier 200b can move along the X-axis direction.

[0129] To facilitate the assembly of the second drive motor 45b, please continue to refer to Fig. 22 and Fig.23The second housing 100b may also include a second base 120b and a second upper cover 130b. In addition, in some examples, two of the four third bosses 110b may be fixedly connected to the second upper cover 130b, and the other two of the third bosses 110b may form an integral structure with the second base 120b, and therefore, this application does not specifically limit this.

[0130] In some possible examples, the first shell 100a of the first driving motor 45a and the second shell 100b of the second driving motor 45b can be respectively integrally formed with the shell structure of the optical lens 41 to form an integral structure.

[0131] For example, see Fig.24 , Fig.24 A schematic structural diagram of the first base 120a, the second base 120b and the shell structure of the optical lens 41 of the camera module 40 provided in the embodiment of the present application being integrally formed. Take the above-mentioned optical lens 41 being arranged between the first drive motor 45a and the second drive motor 45b as an example. The first base 120a of the first drive motor 45a and the second base 120b of the second drive motor 45b can form an integrally formed structure with the shell structure of the optical lens 41, that is, the first base 120a, the second base 120b and the shell structure of the optical lens 41 form a structural component as a whole. In addition, the first upper cover 130a and the second upper cover 130b can be buckled on the corresponding first base 120a and the second base 120b respectively. In this way, it is beneficial to improve the reliability of the overall shell structure of the camera module 40.

[0132] In some other possible examples, the first drive motor 45a, the second drive motor 45b and the optical lens 41 may also be independent components, which can be fixedly connected by gluing, clamping, threading, etc. Therefore, this application does not make any special limitation on this.

[0133] Based on this, the first driving motor 45a and the second driving motor 45b of the camera module 40 provided in the embodiment of the present application can respectively drive the first reflecting element 43a and the second reflecting element 43b to move, so as to adjust the offset of the imaging point in the first direction (i.e., the Z-axis direction) and the second direction (i.e., the Y-axis direction), thereby realizing optical image stabilization. Moreover, the two will not interfere with each other, which is conducive to improving the anti-shake control accuracy and reducing the control difficulty, and is conducive to improving the shooting effect of the camera module 40.

[0134] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0135] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
