Description

Technical Field

[0001] The present application relates to the technical field of electronic equipment, and in particular to a camera module and electronic equipment. Background Art

[0002] Currently, camera modules in electronic devices typically utilize voice coil motors (VCMs) for image stabilization, ensuring stable video footage. However, due to the limited stabilization capabilities of VCMs, camera module stabilization can only offset minor shake during handheld, static shooting. This can also hinder the stability of video footage when users experience significant shaking, such as jogging or cycling. Summary of the Invention

[0003] The embodiments of the present application provide a camera module and an electronic device, which can enable the electronic device to display images normally under high-frequency and large-angle jitter, thereby improving the user experience.

[0004] In a first aspect, the present application provides a camera module, comprising a first reflector, a first shaft, a first bracket and a first actuator arm. The first shaft is connected to the middle area of ​​the first reflector. The first bracket is located on the side of the first shaft away from the first reflector, and is spaced apart from the first shaft. The first actuator arm comprises a first fixed end and a first movable end, the first fixed end is connected to the first bracket, and the first movable end is connected to the first shaft. The first actuator arm is used to deform under the action of voltage so that the first movable end moves relative to the first fixed end, so that the first shaft drives the first reflector to rotate, thereby correcting the light position to achieve optical image stabilization.

[0005] In this embodiment, under the action of voltage, the end of the first actuator arm bends. The first actuator arm can be warped in the direction away from the first bracket. When the first movable end moves, the first movable end drives the first shaft to rotate, so that the distance between the side of the first shaft connected to the first movable end and the first bracket increases, and the first shaft rotates. The first shaft drives the first reflector to rotate. Alternatively, the first actuator arm can be warped in the direction close to the first bracket. By adjusting the position of the first reflector, light can be transmitted to the lens after passing through the first reflector. When the electronic device shakes, the position of the light will change. By adjusting the position of the first reflector, the shake of the light can be offset so that the light is directed to the center area of ​​the lens, thereby achieving an anti-shake effect.

[0006] In addition, the first actuator arm is located on one side of the thickness direction of the first reflective plate. The first actuator arm and the first rotating shaft do not occupy the space around the first reflective plate, and will not cause the length and width dimensions of the camera module to increase, thereby reducing the installation space required for the camera module, which is conducive to the miniaturization of electronic equipment.

[0007] Furthermore, when the first actuator arm causes the first rotating shaft to change its angle, the rotation angle of the first rotating shaft is also the rotation angle of the first reflector. The movement of the first movable end of the first actuator arm can be completely transferred to the first reflector without attenuation. When the first actuator arm undergoes a large deformation, the warping angle of the first actuator arm relative to the first bracket is higher, and the distance between the first movable end of the first actuator arm and the first bracket becomes larger, thereby allowing the first reflector to have a larger angle change and a larger position change. When the electronic device experiences a large angle of shake, the first reflector can adaptively change its angle and position, thereby correcting the shake of the captured image and achieving an anti-shake effect.

[0008] In a possible embodiment, the camera module further includes a second actuator arm, the second actuator arm includes a second fixed end and a second movable end, the second fixed end is connected to the first bracket, the second movable end is connected to the first shaft, and is spaced apart from the first movable end.

[0009] In this embodiment, the second actuator arm can be deformed under the action of voltage. When voltage is applied to the second actuator arm and the first actuator arm, the second movable end can drive the second connector of the first shaft to move, and gradually approach the first bracket. The first movable end drives the first connector of the first shaft to move, and gradually moves away from the first bracket, so that the first shaft rotates. The first shaft drives the first reflector to move, so that the first reflector rotates. When the electronic device shakes, the position of the light input from the environment to the electronic device will change relative to the first reflector. By adjusting the angle of the first reflector, the change in the position of the light can be offset so that the light is directed to the middle area of ​​the lens, thereby achieving an anti-shake effect.

[0010] In one possible embodiment, the camera module further includes a second shaft, a second bracket, a third actuator arm, and a fourth actuator arm, wherein the second shaft is connected to a side of the first bracket facing away from the first actuator arm, the second bracket is located on a side of the second shaft facing away from the first bracket, and the second bracket is spaced apart from the second shaft.

[0011] The third actuator arm includes a third fixed end and a third movable end, the third fixed end is connected to the second bracket, and the third movable end is connected to the second shaft. The fourth actuator arm includes a fourth fixed end and a fourth movable end, the fourth fixed end is connected to the second bracket, and the fourth movable end is connected to the second shaft and is spaced apart from the third movable end.

[0012] In a possible implementation, the direction from the first mobile end toward the second mobile end is a first direction, the direction from the third mobile end toward the fourth mobile end is a second direction, and the first direction intersects the second direction.

[0013] In this embodiment, when voltage is applied to the third and fourth actuator arms, the third movable end drives the third connector of the second shaft to move closer to the second bracket. The fourth movable end drives the fourth connector of the second shaft to move away from the second bracket, causing the second shaft to rotate in the other direction. The second shaft drives the first bracket to rotate. When the electronic device shakes, the second shaking component and the first shaking component can work together to adjust the angle of the first reflector, offsetting the change in the position of the light, so that the light from the first reflector is directed to the middle area of ​​the lens, achieving an anti-shake effect.

[0014] In one possible embodiment, the camera module further includes a distance sensor, an identifier, and a circuit structure, wherein the distance sensor is connected to a surface of the first bracket facing the first reflector, the identifier is connected to a surface of the first reflector facing the first bracket, the distance sensor and the identifier are opposite and spaced apart, and the circuit structure is used to electrically connect the distance sensor to an external device;

[0015] When the relative position between the distance sensor and the identification body changes, the distance sensor generates an electrical signal, and the external device can identify the rotation angle of the first reflector through the electrical signal.

[0016] In this embodiment, the distance sensor can transmit the position change of the first reflector to other components of the electronic device through the circuit structure, so that the electronic device can adjust the angle and position of the first reflector according to the signal sent by the distance sensor, so that the first anti-shake component can respond to the jitter of the light more quickly, so that the first reflector can correct the path of the light.

[0017] In one possible embodiment, the camera module also includes a lens and an image sensor. The lens is located on the side of the first reflector away from the first axis. The lens includes a light-incoming surface and a light-outgoing surface. The light-incoming surface faces the first reflector, and the light-outgoing surface is arranged opposite to the light-incoming surface. The image sensor is located on the side of the light-outgoing surface away from the light-incoming surface.

[0018] In this embodiment, the lens can focus the light reflected by the first reflector and direct it to the image sensor. The lens can also adjust the focal length to make the image of the camera module clearer. The image sensor can convert light signals into electrical signals.

[0019] In one possible embodiment, the camera module further includes a second reflector located on a side of the light-emitting surface facing away from the light-incoming surface and disposed opposite the light-emitting surface and the image sensor. The second reflector is configured to receive light emitted from the light-emitting surface and reflect the light toward the image sensor.

[0020] In this embodiment, the second reflective plate is capable of receiving the light emitted from the light emitting surface and reflecting the light to the image sensor.

[0021] In one possible embodiment, the camera module also includes a third axis, a third bracket, a fifth actuator arm and a sixth actuator arm, the third axis is connected to the side of the image sensor away from the lens, the third bracket is located on the side of the third axis away from the image sensor, and is spaced apart from the third axis.

[0022] The fifth actuator arm includes a fifth fixed end and a fifth movable end, the fifth fixed end is connected to the third bracket, and the fifth movable end is connected to the third shaft. The sixth actuator arm includes a sixth fixed end and a sixth movable end, the sixth fixed end is connected to the third bracket, and the sixth movable end is connected to the third shaft and is spaced apart from the fifth movable end.

[0023] In this embodiment, when voltage is applied to the fifth and sixth actuator arms, the fifth movable end causes one side of the third shaft to move, while the sixth movable end causes another side of the third shaft to move, causing the third shaft to rotate. This in turn causes the image sensor to rotate. When the electronic device experiences significant angular vibration, the position of light traveling from the lens' light-emitting surface to the image sensor may change. Adjusting the angle of the image sensor can offset this change in light position, ensuring that the light reaches the same location on the image sensor, thereby achieving an anti-shake effect.

[0024] In one possible embodiment, the camera module further includes a fourth shaft, a fourth bracket, a seventh actuator arm, and an eighth actuator arm, wherein the fourth shaft is connected to a side of the second reflector facing away from the lens, and the fourth bracket is located on a side of the fourth shaft facing away from the second reflector and is spaced apart from the fourth shaft.

[0025] The seventh actuator arm includes a seventh fixed end and a seventh movable end, the seventh fixed end is connected to the fourth bracket, and the seventh movable end is connected to the fourth axis. The eighth actuator arm includes an eighth fixed end and an eighth movable end, the eighth fixed end is connected to the fourth bracket, and the eighth movable end is connected to the fourth axis and is spaced apart from the seventh movable end.

[0026] In this embodiment, when voltage is applied to the seventh and eighth actuator arms, the seventh movable end drives one side of the fourth axis to move, and the eighth movable end drives the other side of the fourth axis to move, causing the fourth axis to rotate. The fourth axis then drives the second reflector to rotate, thereby rotating the second reflector. When the electronic device experiences significant angular vibration, the position of light emitted from the light-emitting surface of the lens toward the second reflector will change. By adjusting the angle of the second reflector, this change in light position can be offset, so that light reflected from the second reflector is directed toward the center area of ​​the image sensor, thereby achieving an anti-shake effect.

[0027] In a second aspect, the present application also provides a camera module, comprising an image sensor, a shaft, a bracket and an actuator arm. The image sensor comprises a light incident surface and a connecting surface arranged opposite to each other, and the light incident surface is used to receive light emitted by the lens. The shaft is connected to the middle area of ​​the connecting surface. The bracket is located on the side of the shaft away from the image sensor and is spaced apart from the shaft. The actuator arm comprises a fixed end and a movable end, the fixed end is connected to the bracket, and the movable end is connected to the shaft. The actuator arm is used to deform under the action of voltage, so that the movable end moves relative to the fixed end, and the movable end drives the shaft to rotate, so that the shaft drives the image sensor to rotate.

[0028] In a third aspect, the present application provides an electronic device comprising a shake sensor and a camera module as described above, wherein the shake sensor is configured to identify shake parameters of the electronic device and transmit a shake signal based on the shake parameters. A first actuator arm is electrically connected to the shake sensor and configured to drive a first reflector to rotate relative to a first bracket based on the shake signal.

[0040] The specific embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can also be implemented in other ways than those described herein, and therefore, the present application is not limited to the following embodiments.

[0041] For ease of understanding, the terms involved in the embodiments of the present application are first explained.

[0042] Multiple: refers to two or more than two.

[0043] Connection: should be understood in a broad sense. For example, A and B are connected, which can be either directly connected or indirectly connected through an intermediary.

[0044] The specific implementation of the present application will be clearly described below with reference to the accompanying drawings.

[0045] See also Figure 1 , Figure 1 1 is a schematic diagram of the structure of an electronic device 100 provided in an embodiment of the present application. The electronic device 100 includes a housing 10, a vibration sensor (not shown), and a camera module 20. The electronic device 100 may be a smart consumer electronic device such as a mobile phone, a tablet computer, or a laptop computer. Alternatively, the electronic device 100 may be a wearable device such as augmented reality (AR), virtual reality (VR), smart glasses, smart goggles, or a smart watch that can be configured with a camera module 20.

[0046] The jitter sensor is used to identify the jitter parameters of the electronic device, such as the frequency and angle of the jitter, etc., and sends a jitter signal to the processor of the electronic device based on the jitter parameters. The processor can control the camera module to perform anti-shake action based on the jitter parameters. Exemplarily, the jitter sensor can be an acceleration sensor (G-sensor) and / or a gyroscope sensor, etc. Among them, the acceleration sensor can detect the acceleration change of the electronic device 100 in three axes, so as to determine whether the electronic device 100 is shaking. The gyroscope sensor can detect the angular velocity change of the electronic device 100 in space, that is, the angular velocity of the rotation of the electronic device 100, so as to determine whether the electronic device 100 is shaking and the direction of the shaking.

[0047] The camera module 20 is installed inside the housing 10. The camera module 20 is electrically connected to the vibration sensor. The camera module 20 can perform anti-shake action according to the vibration signal.

[0048] Currently, when electronic devices are in use, shaking can cause unstable images. Anti-shake technology is generally used in electronic devices to improve the display quality of captured images. Anti-shake technology can correct the shaking of the electronic device, resulting in a more stable and clearer image.

[0049] When an electronic device shakes, both the frequency and angle of the shake affect the stability of the captured image. The frequency of the shake refers to the speed at which the device shakes. If the frequency of the shake is high, the anti-shake system needs to respond more quickly to correct the shaking and maintain a stable image.

[0050] When an electronic device experiences a certain degree of vertical or horizontal deviation, its anti-shake system measures the angle of the shake and corrects it for the captured image. However, if the angle of the shake is too large, it may exceed the angle that the anti-shake system can correct, causing the captured image to lose balance and produce artifacts.

[0051] The camera module 20 provided in the embodiment of the present application is provided with an anti-shake component, which enables the camera module 20 to display images normally under high-frequency and large-angle shaking, thereby improving the user experience.

[0052] For a first possible embodiment, see Figure 2 , Figure 2 yes Figure 1 The camera module 20 includes a lens 21, a first reflector 22, an image sensor 23, a first anti-shake component 24, a distance sensor ( Figure 2 Not shown), Identifier ( Figure 2 Not shown) and circuit structure ( Figure 2(Not shown). The lens 21 includes a light-incoming surface 211 and a light-outgoing surface 212. The lens 21 is configured to converge light entering through the light-incoming surface 211 and emit the light through the light-outgoing surface 212. A first reflector 22 is located on the light-incoming surface 211 of the lens 21 and is configured to reflect light toward the lens 21. An image sensor 23 is located on the light-outgoing surface 212 of the lens 21 and is configured to receive light emitted from the light-outgoing surface 212 of the lens 21. A first anti-shake assembly 24 can be mounted on the side of the first reflector 22 facing away from the lens 21.

[0053] It should be noted that Figure 2 The purpose is only to schematically describe the connection relationship between the lens 21, the first reflector 22, the image sensor 23 and the first anti-shake component 24, and it does not specifically limit the connection position, specific structure and quantity of each device. The structure illustrated in the embodiment of the present application does not constitute a specific limitation on the camera module 20. In other embodiments of the present application, the camera module 20 may include more or fewer components than shown in the figure, or combine certain components, or split certain components, or arrange the components differently. The illustrated components can be implemented in hardware, software, or a combination of software and hardware.

[0054] The lens 21 can converge the light reflected by the first reflector 22 and converge the light onto the image sensor 23. The lens 21 can also adjust the focal length to make the imaging of the camera module 20 clearer. Exemplarily, the lens 21 can be composed of multiple optical lenses. Among them, the optical axes of the multiple optical lenses can coincide. The light input surface 211 and the light output surface 212 of the lens 21 are arranged in opposite directions along the extension direction of the optical axis. The material of the multiple optical lenses can be glass, plastic, etc.

[0055] It should be noted that the lens 21 provided in the present application can be fixedly connected to the housing 10 of the electronic device 100, that is, during the use of the electronic device 100, the relative position of the lens 21 and the housing 10 of the electronic device 100 does not change.

[0056] The first reflector 22 is located on the side of the light-incoming surface 211 of the lens 21 facing away from the light-emitting surface 212. A gap exists between the first reflector 22 and the light-incoming surface 211 of the lens 21. The first reflector 22 is arranged at an angle to the plane of the light-incoming surface 211. The first reflector 22 is configured to receive external light and reflect it toward the light-incoming surface 211 of the lens 21.

[0057] The image sensor 23 is located on the side of the light-emitting surface 212 of the lens 21 facing away from the light-incoming surface 211. The image sensor 23 is spaced apart from and disposed opposite the light-emitting surface 212 of the lens 21. The image sensor 23 is capable of converting optical signals into electrical signals. The electrical signals can be processed by other components in the electronic device 100 to form an image. The image sensor 23 can be directly or indirectly fixedly connected to the housing of the electronic device 100. In other words, the relative position of the image sensor 23 and the housing of the electronic device 100 does not change during use of the electronic device 100.

[0058] When the camera module 20 is in use, external light can be transmitted to the first reflector 22. After being reflected by the first reflector 22, the light is emitted to the light-incoming surface 211 of the lens 21. After being converged by the lens 21, the light is emitted from the light-emitting surface 212 and emitted to the image sensor 23 to form an image.

[0059] However, during current use, users generally hold electronic devices in their hands to take pictures, so the electronic devices will inevitably shake. When the angle and path position of the light reflected by the external object transmitted to the first reflector changes, the light signal received by the image sensor is unstable, resulting in the electronic device being unable to form a stable image through the light signal.

[0060] Based on this, the present application uses the first anti-shake component 24 to buffer the shaking action of the first reflector 22, so that the relative position of the light reflected by the first reflector 22 and the lens 21 does not change as much as possible, thereby making the light signal reaching the image sensor 23 more stable, so that the image sensor 23 display is more stable.

[0061] See also Figure 3 , Figure 3 yes Figure 2 The figure shows an exploded schematic diagram of the first anti-shake assembly 24 and the first reflector 22. When no voltage is applied to the first anti-shake assembly 24, the X direction in the figure is the width direction of the first reflector 22. The Y direction in the figure is the length direction of the first reflector 22. The Z direction in the figure is the axial direction of the first reflector 22.

[0062] The first anti-shake assembly 24 includes a first shaft 241 , a first actuating arm 242 , a second actuating arm 243 , and a first bracket 244 . The first actuating arm 242 and the second actuating arm 243 are connected between the first shaft 241 and the first bracket 244 .

[0063] The first shaft 241 can be cylindrical. The axial direction of the cylinder can be arranged along the Z direction. When no voltage is applied to the first anti-shake assembly, the central axis of the first shaft 241 can intersect the optical axis of the lens 21. In other words, the central axis of the first shaft 241 can be coplanar with the optical axis of the lens 21. The first shaft 241 includes a first subsection 2411 and a second subsection 2412. The first subsection 2411 and the second subsection 2412 are arranged sequentially along the Z direction.

[0064] The second sub-section 2412 includes a first connector 2413 and a second connector 2414. The first connector 2413 and the second connector 2414 may be located on the sides of the second sub-section 2412. The first connector 2413 and the second connector 2414 are disposed opposite each other along the radial direction of the second sub-section 2412. The first connector 2413 and the second connector 2414 are disposed opposite each other in the Y direction.

[0065] The second sub-portion 2412 of the first shaft body 241 faces the first reflector 22. The second sub-portion 2412 of the first shaft body 241 is fixedly connected to the middle area of ​​the first reflector 22 with its bottom surface facing away from the first sub-portion 2411.

[0066] In this embodiment, the first shaft 241 can support the first reflective plate 22 .

[0067] The first bracket 244 includes a bracket body 2441, a first limiting body 2442, a second limiting body 2443 and a buffer body 2444. The bracket body 2441 may be plate-shaped.

[0068] The first position limiting member 2442 is connected to the periphery of the bracket body 2441. The first position limiting member 2442 may include a first plate 2445 and a second plate 2446. The first plate 2445 and the second plate 2446 are connected by a bend. One end of the first plate 2445, which is away from the second plate 2446, is connected to a side edge of the bracket body 2441 in the width direction. The orthographic projection of the second plate 2446 onto the bracket body 2441 covers at least a portion of the bracket body 2441.

[0069] The second limiting member 2443 is connected to the periphery of the bracket body 2441. The second limiting member 2443 may include a third plate 2447 and a fourth plate 2448. The third plate 2447 and the fourth plate 2448 are connected by a bend. The end of the third plate 2447, which is remote from the fourth plate 2448, is connected to a side edge of the bracket body 2441 in the longitudinal direction. The orthographic projection of the fourth plate 2448 onto the bracket body 2441 covers at least a portion of the bracket body 2441.

[0070] The buffer body 2444 may be disposed on one side of the bracket body 2441 facing the second plate 2446 of the first limiting portion and the fourth plate 2448 of the second limiting body 2443. For example, the buffer body 2444 may be a buffer cotton.

[0071] The first bracket 244 is located on a side of the first sub-portion 2411 of the first shaft 241 facing away from the first reflector 22. The first bracket 244 is spaced apart from the first sub-portion 2411 of the first shaft 241. The first bracket 244 is fixedly connected to the housing 10 of the electronic device 100. The first bracket 244 can be directly connected to the housing 10 of the electronic device 100, or the first bracket 244 can be indirectly connected to the housing 10 of the electronic device 100 through other structural members. During use of the electronic device 100, the relative position of the first bracket 244 and the electronic device 100 does not change.

[0072] After the first bracket 244 is assembled with the first reflector 22, the bracket body 2441 of the first bracket 244 is spaced apart from and opposite to the first reflector 22. The second plate 2446 of the first position-limiting body 2442 can be located on a side of the first reflector 22 facing away from the bracket body 2441, with the second plate 2446 spaced apart from the first reflector 22. The fourth plate 2448 of the second position-limiting body 2443 can be located on a side of the first reflector 22 facing away from the bracket body 2441, with the fourth plate 2448 spaced apart from the first reflector 22. The buffer body 2444 is located between the first reflector 22 and the bracket body 2441. The buffer body 2444 can be spaced apart from the first reflector 22.

[0073] In this embodiment, the first reflector 22 can rotate or translate relative to the first bracket 244. The first limiter 2442 and the second limiter 2443 can prevent the first reflector 22 from rotating too much, which could cause the first reflector 22 to fall off the first shaft 241 of the first anti-shake assembly 24. The buffer 2444 can prevent the first reflector 22 from making hard contact with the bracket body 2441, thereby preventing damage to the structure of the first reflector 22, or prevent the first reflector 22 from squeezing the first actuator arm 242 and / or the second actuator arm 243, thereby causing deformation of the actuator arms.

[0074] The first actuator arm 242 includes a first section 2421 and a second section 2422. The first section 2421 includes a first fixed end 2423. The first section 2421 may be in the shape of an elongated strip and may extend along the X-direction. The first fixed end 2423 is connected to the first bracket 244. For example, the first actuator arm 242 may further include a first spacer 2425. The first spacer 2425 may be disposed between the first fixed end 2423 and the first bracket 244. This creates a certain gap between the first section 2421 and the first bracket 244, thereby reserving space for the first actuator arm 242 to move.

[0075] The second section 2422 includes a first movable end 2424. The second section 2422 can be in the shape of an elongated strip. The second section 2422 can extend along the Y direction. The first movable end 2424 of the second section 2422 is connected to the first connector 2413 of the first shaft 241. Specifically, the first movable end 2424 is connected to the surface of the first connector 2413 facing the first subsection 2411. The first movable end 2424 is spaced apart from the periphery of the first subsection 2411. Exemplarily, the first movable end 2424 and the first subsection 2411 can be rotatably connected via a rotating shaft. This allows the first movable end 2424 and the first shaft 241 to rotate relative to each other when the first actuator arm 242 is deformed. Alternatively, the first movable end 2424 can be connected to the first connector 2413 of the first shaft 241 via a flexible structure, wherein the flexible structure can undergo telescopic deformation. This application does not limit the connection method between the first movable end 2424 and the first shaft 241.

[0076] The other end of the second section 2422 away from the first movable end 2424 is bent and connected to the other end of the first section 2421 away from the first fixed end 2423. The second section 2422 and the first section 2421 can be arranged perpendicular to each other.

[0077] In this embodiment, in a first possible usage scenario, under the action of a voltage, the distal end of the first actuator arm 242 bends. The first actuator arm 242 can warp in a direction away from the first bracket 244. Specifically, the end of the first section 2421 of the first actuator arm 242, distal to the first fixed end 2423, can warp in a direction away from the first bracket 244, causing the second section 2422 to move as a whole in a direction away from the first bracket 244. As the second section 2422 gradually moves away from the first bracket 244, the first movable end 2424 of the second section 2422 warps in a direction away from the first bracket 244. The distance between the first movable end 2424 of the second section 2422 and the first bracket 244 is greater than the maximum distance between the first section 2421 and the first bracket 244.

[0078] When the first movable end 2424 moves, it drives one side of the first shaft 241 to move, increasing the distance between the side of the first shaft 241 connected to the first movable end and the first bracket 244. The first shaft 241 drives the first reflector 22 to rotate, causing the relative position of the first reflector 22 and the first bracket 244 to change. By adjusting the position of the first reflector 22, light can be transmitted through the first reflector 22 toward the lens 21. When the electronic device 100 shakes, the position of the light will change. By adjusting the position of the first reflector 22, the light shake can be offset so that the light is directed toward the center area of ​​the lens 21, thereby achieving an anti-shake effect.

[0079] In addition, the first actuator arm 242 is located on one side of the thickness direction of the first reflective plate 22. The first actuator arm 242 and the first rotating shaft do not occupy the space around the first reflective plate 22, and will not cause the length and width dimensions of the camera module 20 to increase, thereby reducing the installation space required for the camera module 20, which is conducive to the miniaturization of the electronic device 100.

[0080] Furthermore, when the first actuating arm 242 causes the first rotating shaft to change its angle, the rotation angle of the first rotating shaft also corresponds to the rotation angle of the first reflector 22. The movement of the first movable end 2424 of the first actuating arm 242 can be fully transferred to the first reflector 22 without attenuation. When the first actuating arm 242 undergoes significant deformation, the warping angle of the first actuating arm 242 relative to the first bracket 244 increases, and the distance between the first movable end 2424 of the first actuating arm 242 and the first bracket 244 increases, thereby allowing the first reflector 22 to experience a greater angular change. When the electronic device 100 experiences significant shaking, the first reflector 22 can adaptively change its angle, thereby correcting the shaking in the captured image and achieving an anti-shake effect.

[0081] In a second possible usage scenario, the first actuator arm 242 can be warped toward the first bracket 244. Specifically, the end of the first section 2421 of the first actuator arm 242, away from the first fixed end 2423, can be moved toward the first bracket 244, causing the second section 2422 as a whole to move farther away from the first bracket 244. As the second section 2422 moves away from the first section 2421, it gradually approaches the first bracket 244. The distance between the first movable end 2424 of the second section 2422 and the first reflector 22 is less than the minimum distance between the first section 2421 and the first reflector 22.

[0082] Please continue reading Figure 3 The second actuator arm 243 includes a third section 2431 and a fourth section 2432. The third section 2431 can extend along the X direction. The third section 2431 includes a second fixed end 2433. The second fixed end 2433 is connected to the first bracket 244.

[0083] The fourth segment 2432 can extend along the Y-direction. The fourth segment 2432 includes a second movable end 2434. The second movable end 2434 is connected to the second connector 2414 of the first axle 241. Specifically, the second movable end 2434 is connected to the surface of the second connector 2414 facing the first sub-section 2411. The second connector end is spaced apart from the periphery of the first sub-section 2411. The other end of the fourth segment 2432, away from the second movable end 2434, is bent and connected to the other end of the third segment 2431, away from the first fixed end 2423.

[0084] The second actuating arm 243 can be centrally symmetrical with the first actuating arm 242 along the axis of the first shaft 241. The specific structure of the third section 2431 of the second actuating arm 243 can be found in the above description of the first section 2421 of the first actuating arm 242. The specific structure of the fourth section 2432 of the second actuating arm 243 can be found in the above description of the second section 2422 of the first actuating arm 242. This application does not further describe the structure of the second actuating arm 243.

[0085] In this embodiment, please refer to Figure 3 and Figure 4 , Figure 4 yes Figure 3 Schematic diagram of the structure of the cooperation of part of the first anti-shake component 24 and the first reflector 22 shown. The second actuator arm 243 can be deformed under the action of voltage. The second actuator arm 243 can be warped in the direction close to the first bracket 244. Specifically, the end of the third section 2431 of the second actuator arm 243 away from the second fixed end 2433 can be moved toward the first bracket 244, so that the fourth section 2432 as a whole moves toward the first bracket 244. In the direction gradually away from the third section 2431, the fourth section 2432 gradually approaches the first bracket 244, and the distance between the second movable end 2434 of the fourth section 2432 and the first bracket 244 is less than the minimum distance between the third section 2431 and the first bracket 244.

[0086] When voltage is applied to the second actuator arm 243 and the first actuator arm 242, the second movable end 2434 drives the second connector 2414 of the first shaft 241 to move, gradually approaching the first bracket 244. The first movable end 2424 drives the first connector 2413 of the first shaft 241 to move, gradually moving away from the first bracket 244. This causes the first shaft 241 to rotate along the X-axis, causing the axis of the first shaft 241 to rotate within the plane of the Y and Z directions. At this point, the axis of the first shaft 241 forms an angle with the Z and Y directions. The first shaft 241 drives the first reflector 22 to rotate, adjusting the angle of the first reflector 22. When the electronic device 100 shakes, the position of the ambient light input to the electronic device 100 changes relative to the first reflector 22. By adjusting the angle of the first reflector 22, this change in the light's position can be offset, allowing the light to be directed toward the center area of ​​the lens 21, thereby achieving an anti-shake effect.

[0087] Please refer to Figure 3 The identification body 245 is connected to the surface of the first reflective plate 22 facing the bracket body 2441. For example, the identification body 245 can be a magnet.

[0088] The distance sensor 246 is connected to the surface of the bracket body 2441 facing the first reflector 22. The identification body 245 is opposite to and spaced apart from the distance sensor 246. For example, the distance sensor 246 can be a Hall sensor.

[0089] In this embodiment, when the relative position of the distance sensor 246 and the identification body 245 changes, the distance sensor 246 can generate an electrical signal. Other components of the electronic device 100 can use this electrical signal to identify the change in the position of the first reflector 22 relative to the bracket body 2441, thereby calculating the rotation angle of the first reflector 22. The rotation angle of the first reflector 22 can be adjusted to accommodate the degree of light jitter relative to the electronic device 100, thereby correcting the jittered light and ensuring a more stable image captured by the electronic device 100.

[0090] The circuit structure 247 is electrically connected to the first fixed end 2423 of the first actuator arm 242, the second fixed end 2433 of the second actuator arm 243, and the distance sensor 246. The circuit structure 247 is used to apply voltage to the first actuator arm 242 and the second actuator arm 243 and electrically connect the distance sensor 246 to external devices.

[0091] In this embodiment, the distance sensor 246 can transmit the position edge of the first reflector 22 to other devices of the electronic device 100 through the circuit structure 247, so that the electronic device 100 can adjust the angle and position of the first reflector 22 according to the signal sent by the distance sensor 246, so that the first anti-shake component 24 can respond to the jitter of the light more quickly, so that the first reflector 22 can correct the path of the light.

[0092] For a second possible embodiment, see Figure 5 , Figure 5 yes Figure 2 FIG2 is a partial structural diagram of a second embodiment of the camera module 20. The structure of the first anti-shake assembly 24 of the second embodiment is different from that of the first anti-shake assembly 24 of the first embodiment in that the first actuator arm 242 and the second actuator arm 243 of the first anti-shake assembly 24 of the second embodiment are curved lever arms.

[0093] In this embodiment, when the first actuator arm 242 and the second actuator arm 243 are arranged in a curved shape, the first actuator arm 242 and the second actuator arm 243 are smaller in size and occupy a smaller installation space, thereby leaving more space between the first bracket 244 and the first reflector 22 for the installation of the circuit structure 247, the distance sensor 246, the identification element, and other required components.

[0094] A third possible embodiment. Figure 6 , Figure 6 yes Figure 2 Schematic diagram of the structure of the third embodiment of the camera module 20. The structure of the camera module 20 of the third embodiment is different from that of the camera module 20 of the first embodiment in that the camera module 20 of the third embodiment further includes a second anti-shake component (not shown) connected to the first bracket 244.

[0095] The second anti-shake assembly includes a second shaft 251 , a second bracket 252 , a third actuating arm 253 and a fourth actuating arm 254 .

[0096] The second shaft body 251 can be a cylinder. The axial direction of the cylinder can be arranged along the Z direction. The second shaft body 251 includes a third sub-section 2511 and a fourth sub-section 2512. The third sub-section 2511 and the fourth sub-section 2512 are arranged in sequence along the Z direction.

[0097] The fourth sub-section 2512 includes a third connector 2513 and a fourth connector 2514. The third connector 2513 and the fourth connector 2514 may be located on the side of the fourth sub-section 2512. The third connector 2513 and the fourth connector 2514 are disposed opposite to each other in the X direction.

[0098] The fourth subsection 2512 of the second shaft 251 faces the first bracket 244. The bottom surface of the fourth subsection 2512 of the second shaft 251, facing away from the third subsection 2511, is fixedly connected to the middle area of ​​the surface of the first bracket 244 facing away from the first actuator arm 242. When no voltage is applied to the second anti-shake assembly, the central axis of the second shaft 251 can intersect with the optical axis of the lens 21. In other words, the central axis of the second shaft 251 can be coplanar with the optical axis of the lens 21.

[0099] In this embodiment, the second shaft 251 can support the first bracket 244. It should be noted that in this embodiment, the first bracket 244 is supported by the second shaft 251, and the relative arrangement of the first bracket 244 and the housing 10 of the electronic device 100 can be adjusted by the second anti-shake component.

[0100] The second bracket 252 is located on the side of the second shaft 251 away from the first bracket 244. The second bracket 252 is spaced apart from the second shaft 251. The second bracket 252 is connected to the housing 10 of the electronic device 100. The second bracket 252 is fixedly connected to the electronic device 100. Exemplarily, the second bracket 252 can be directly connected to the housing 10 of the electronic device 100, or the second bracket 252 can be indirectly connected to the housing 10 of the electronic device 100 through other structural members. During the use of the electronic device 100, the relative position of the second bracket 252 and the electronic device 100 does not change.

[0101] The third actuating arm 253 includes a third fixed end 2531 and a third movable end 2532 . The third fixed end 2531 is connected to the second bracket 252 . The third movable end 2532 is connected to a surface of the third connecting body 2513 of the second shaft body 251 facing the third sub-portion 2511 .

[0102] The fourth actuating arm 254 includes a fourth fixed end 2541 and a fourth movable end 2542. The fourth fixed end 2541 is connected to the second bracket 252, and the fourth movable end 2542 is connected to the surface of the fourth connecting body 2514 of the second shaft body 251 that faces the fourth sub-section 2512. The fourth movable end 2542 is spaced apart from the third movable end 2532. Exemplarily, the fourth actuating arm 254 and the third actuating arm 253 may be centrally symmetrical about the axis of the second shaft body 251.

[0103] The specific structures of the third actuating arm 253 and the fourth actuating arm 254 in this embodiment can be found in the above description of the first actuating arm 242 , and this application does not elaborate on the specific structures of the third actuating arm 253 and the fourth actuating arm 254 .

[0104] When no voltage is applied to the first actuator arm 242, the second actuator arm 243, the third actuator arm 253, and the fourth actuator arm 254, the direction from the first movable end 2424 toward the second movable end 2434 is a first direction (Y direction), and the direction from the third movable end 2532 toward the fourth movable end 2542 is a second direction (X direction). The first direction intersects the second direction. For example, the first direction is perpendicular to the second direction.

[0105] In this embodiment, when voltage is applied to the third actuator arm 253 and the fourth actuator arm 254, the third movable end 2532 drives the third connecting body 2513 of the second shaft body 251 to move closer to the second bracket 252. The fourth movable end 2542 drives the fourth connecting body 2514 of the second shaft body 251 to move away from the second bracket 252. The second shaft body 251 is rotated along the Y-axis, so that the axis of the second shaft body 251 rotates in the plane where the X-direction and the Z-direction are located. The second shaft body 251 drives the first bracket 244 to rotate. When the electronic device 100 shakes, the second shaking component and the first shaking component can work together to adjust the angle of the first reflector 22 and offset the change in the position of the light, so that the light from the first reflector 22 is directed to the middle area of ​​the lens 21, thereby achieving an anti-shake effect.

[0106] A fourth possible embodiment. Figure 7 , Figure 7 yes Figure 2FIG2 is a partial structural diagram of a fourth embodiment of the camera module 20 shown in FIG2. The structure of the camera module 20 of the fourth embodiment is different from that of the camera module 20 of the first embodiment in that the camera module 20 of the fourth embodiment further includes a third anti-shake component (not shown) connected to the image sensor 23.

[0107] The third anti-shake assembly includes a shaft, a bracket, and two actuator arms. For ease of description, the shaft of the third anti-shake assembly is referred to as the third shaft 261. The bracket of the third anti-shake assembly is referred to as the third bracket 262. The two actuator arms of the third anti-shake assembly are the fifth actuator arm 263 and the sixth actuator arm 264.

[0108] The third shaft 261 is connected to the side of the image sensor 23 facing away from the lens 21. The central axis of the third shaft 261 can be perpendicular to the plane of the image sensor 23. When no voltage is applied to the third anti-shake assembly, the central axis of the third shaft 261 can coincide with the optical axis of the lens 21. The specific structure of the third shaft 261 can be found in the above description of the structure of the first shaft 241. This application does not further describe the structure of the third shaft 261.

[0109] The third bracket 262 is located on a side of the third shaft 261 facing away from the image sensor 23, and is spaced apart from the third shaft 261. The specific structure of the third bracket 262 can be found in the above description of the structure of the first bracket 244. This application does not elaborate on the structure of the third bracket 262.

[0110] The fifth actuating arm 263 includes a fifth fixed end 2631 and a fifth movable end 2632. The fifth fixed end 2631 is connected to the third bracket 262, and the fifth movable end 2632 is connected to the third shaft 261. The specific structure of the fifth actuating arm 263 can be found in the description of the first actuating arm 242 above. This application does not further describe the specific structure of the fifth actuating arm 263.

[0111] The sixth actuator arm 264 includes a sixth fixed end 2641 and a sixth movable end 2642. The sixth fixed end 2641 is connected to the third bracket 262, and the sixth movable end 2642 is connected to the third shaft 261. The sixth movable end 2642 is spaced apart from the fifth movable end 2632. The direction from the sixth movable end 2642 toward the fifth movable end 2632 can be the X-direction. The specific structure of the sixth actuator arm 264 can be found in the description of the first actuator arm 242 above. This application does not further describe the specific structure of the sixth actuator arm 264.

[0112] In this embodiment, when voltage is applied to the fifth actuator arm 263 and the sixth actuator arm 264, the fifth movable end 2632 drives one side of the third shaft 261 to move, and the sixth movable end 2642 drives one side of the third shaft 261 to move. The two opposite sides of the third shaft 261 move in opposite directions along the X-axis, causing the third shaft 261 to rotate. At this time, the central axis of the third shaft 261 is arranged at an acute angle to the X-axis. The third shaft 261 drives the image sensor 23 to rotate, thereby rotating the image sensor 23. When the electronic device 100 experiences a large-angle shake, the position of the light emitted from the light-emitting surface 212 of the lens 21 to the image sensor 23 will change. By adjusting the angle of the image sensor 23, the change in the light position can be offset so that the light is emitted to the same position on the image sensor 23, thereby achieving an anti-shake effect.

[0113] In addition, since the third anti-shake component can rotate the image sensor 23 relative to the width direction (X direction) of the image sensor 23, the first anti-shake component 24 can rotate the first reflector 22 relative to the Y direction, so that the camera module 20 can simultaneously adjust the angle of the light in the X direction and the Y direction, thereby achieving an anti-shake effect.

[0114] In the fifth possible embodiment, please refer to Figure 8 and Figure 9 , Figure 8 yes Figure 2 FIG. 1 is a partial structural diagram of a fifth embodiment of the camera module 20 shown in FIG. Figure 9 yes Figure 8 The structure of the camera module 20 of the fifth embodiment is different from that of the camera module 20 of the first embodiment in that the camera module 20 of the fifth embodiment further includes a second reflector 27 and a fourth anti-shake assembly (not shown) connected to the second reflector 27.

[0115] The second reflector 27 is located on the side of the light-emitting surface 212 of the lens 21 that is opposite the light-incoming surface 211. The second reflector 27 is positioned opposite both the light-emitting surface 212 and the image sensor 23. The second reflector 27 receives light emitted from the light-emitting surface 212 and reflects it toward the image sensor 23. When no voltage is applied to either the first anti-shake assembly 24 or the second anti-shake assembly, the second reflector 27 can be positioned parallel to the first reflector 22.

[0116] The image sensor 23 is configured to receive light reflected by the second reflector 27. The light-receiving surface of the image sensor 23 is disposed at an acute angle to the light-reflecting surface of the second reflector 27. For example, the light-receiving surface of the image sensor 23 may be disposed perpendicular to the light-emitting surface 212 of the lens 21.

[0117] The fourth anti-shake assembly is located on the side of the second reflector 27 away from the lens 21. The fourth anti-shake assembly includes a fourth shaft 271, a fourth bracket 272, a seventh actuating arm 273 and an eighth actuating arm 274.

[0118] The fourth shaft 271 is connected to the side of the second reflector 27 facing away from the lens 21. The central axis of the fourth shaft 271 can be perpendicular to the plane where the second reflector 27 is located. When no voltage is applied to the fourth anti-shake assembly. The central axis of the fourth shaft 271 can intersect with the optical axis of the lens 21. That is, the central axis of the fourth shaft 271 can be in the same plane as the optical axis of the lens 21. The specific structure of the fourth shaft 271 can refer to the structural description of the first shaft 241 above. This application does not elaborate on the structure of the fourth shaft 271.

[0119] The fourth bracket 272 is located on the side of the fourth shaft 271 away from the second reflector 27, and is spaced apart from the fourth shaft 271. The specific structure of the fourth bracket 272 can be found in the above description of the structure of the first bracket 244. This application does not elaborate on the structure of the fourth bracket 272.

[0120] The seventh actuating arm 273 includes a seventh fixed end 2731 and a seventh movable end 2732. The seventh fixed end 2731 is connected to the fourth bracket 272, and the seventh movable end 2732 is connected to the fourth shaft 271. The specific structure of the seventh actuating arm 273 can be found in the description of the first actuating arm 242 above. This application does not further describe the specific structure of the seventh actuating arm 273.

[0121] The eighth actuator arm 274 includes an eighth fixed end 2741 and an eighth movable end 2742. The eighth fixed end 2741 is connected to the fourth bracket 272, and the eighth movable end 2742 is connected to the fourth shaft 271. The eighth movable end 2742 is spaced apart from the seventh movable end 2732. The direction from the eighth movable end 2742 toward the seventh movable end 2732 can be the X direction. The specific structure of the eighth actuator arm 274 can be found in the description of the first actuator arm 242 above. This application does not further describe the specific structure of the eighth actuator arm 274.

[0122] In this embodiment, when voltage is applied to the seventh and eighth actuator arms 273 and 274, the seventh movable end 2732 moves one side of the fourth shaft 271, while the eighth movable end 2742 moves the other side of the fourth shaft 271. The two opposing sides of the fourth shaft 271 along the X-direction move in opposite directions, causing the fourth shaft 271 to rotate. At this point, the central axis of the fourth shaft 271 forms an acute angle with the X-axis. The fourth shaft 271 drives the second reflector 27 to rotate.

[0123] When the electronic device 100 shakes at a large angle, the position of the light emitted from the light-emitting surface 212 of the lens 21 to the second reflector 27 will change. By adjusting the angle of the second reflector 27, the change in the position of the light can be offset so that the light reflected from the second reflector 27 is directed to the middle area of ​​the image sensor 23, thereby achieving an anti-shake effect.

[0124] In addition, since the fourth anti-shake component can rotate the image sensor 23 relative to the X direction, the first anti-shake component 24 can rotate the first reflector 22 relative to the Y direction, so that the camera module 20 can simultaneously adjust the angle of the light in the X direction and the Y direction, thereby achieving an anti-shake effect.

[0125] For the sixth possible embodiment, please refer to Figure 10 , Figure 10 yes Figure 2 FIG2 is a partial structural diagram of a sixth embodiment of the camera module 20. Unlike the camera module 20 of the fifth embodiment, the camera module 20 of the sixth embodiment may further include a fifth anti-shake component (not shown), which is located on a side of the fourth anti-shake component away from the second reflector 27.

[0126] The fifth anti-shake assembly includes a fifth shaft 281 , a fifth bracket 282 , a ninth actuating arm 283 and a tenth actuating arm 284 .

[0127] The fifth shaft 281 is connected to the side of the second reflector 27 facing away from the lens 21. The central axis of the fifth shaft 281 can be perpendicular to the plane of the second reflector 27. When no voltage is applied to the fifth anti-shake assembly, the central axis of the fifth shaft 281 can intersect the optical axis of the lens 21. In other words, the central axis of the fifth shaft 281 can be coplanar with the optical axis of the lens 21.

[0128] The specific structure of the fifth shaft 281 can refer to the above description of the structure of the first shaft 241. The present application does not elaborate on the structure of the fifth shaft 281.

[0129] The fifth bracket 282 is located on the side of the fifth shaft 281 away from the second reflector 27, and is spaced apart from the fifth shaft 281. The specific structure of the fifth bracket 282 can be found in the above description of the structure of the first bracket 244. This application does not elaborate on the structure of the fifth bracket 282.

[0131] The specific structure of the ninth actuating arm 283 can be found in the above description of the first actuating arm 242. The specific structure of the ninth actuating arm 283 is not described in detail in this application.

[0132] The tenth actuator arm 284 includes a tenth fixed end 2841 and a tenth movable end 2842. The tenth fixed end 2841 is connected to the fifth bracket 282, and the tenth movable end 2842 is connected to the fifth shaft 281. The tenth movable end 2842 is spaced apart from the ninth movable end 2832. The direction from the tenth movable end 2842 to the ninth movable end 2832 can be the X direction.

[0133] The specific structure of the tenth actuating arm 284 can refer to the above description of the first actuating arm 242. The specific structure of the tenth actuating arm 284 is not described in detail in this application.

[0134] In this embodiment, the ninth movable end 2832 can be warped in a direction away from the fifth bracket 282, and the tenth movable end 2842 can be warped in a direction toward the fifth bracket 282, so that the fifth bracket 282 can rotate along the Y-axis, thereby driving the second anti-shake assembly and the second reflector 27 to rotate along the Y-axis. The fifth anti-shake assembly and the second anti-shake assembly can be such that the second reflector 27 can rotate along the Y-axis and the X-axis, so that the angle of the second reflector 27 relative to the light exit surface 212 of the lens 21 can be adjusted. The position of light emitted from the light exit surface 212 of the lens 21 to the second reflector 27 will change. By adjusting the angle of the second reflector 27, the change in the position of the light can be offset, so that the light reflected from the second reflector 27 is emitted to the same position on the image sensor 23, thereby achieving an anti-shake effect.

[0135] The above is an exemplary embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made thereto without departing from the principles of the present application. These improvements and modifications are also considered to be within the scope of protection of the present application.
