Description

Motors, camera modules and electronic devices

[0001] This application claims priority to Chinese Patent Application No. 202410517718.1, filed with the China National Intellectual Property Administration on April 26, 2024, entitled "Motor, Camera Module and Electronic Device", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of shooting equipment technology, specifically to a motor, camera module and electronic equipment. Background Technology

[0003] With the continuous development of electronic device technology, shooting function has become an important feature of electronic devices (such as mobile phones, tablets, etc.) and an important indicator for evaluating the performance of electronic devices. Existing camera modules usually have optical image stabilization (OIS) to improve image quality. When performing optical image stabilization, it is usually achieved by a motor driving the head-up and head-down movement of a prism or mirror to compensate for shake.

[0004] However, jitter compensation achieved by rotating a prism or mirror can easily lead to image rotation problems, affecting image quality. Summary of the Invention

[0005] This application provides a motor, a camera module, and an electronic device. The motor includes a frame, a first actuating arm, and a second actuating arm. Both the first and second actuating arms are mounted on the frame. The first and second actuating arms drive the image sensor to move, thereby achieving image stabilization, reducing or even eliminating image rotation problems, and improving the imaging quality of the image sensor.

[0006] In a first aspect, this application provides a motor. The motor includes a frame, a first actuating arm, and a second actuating arm, both of which are mounted on the frame. A first end of the first actuating arm is used to connect to an image sensor. The first actuating arm deforms when energized, causing the image sensor to move along a first direction, which is parallel to the photosensitive surface of the image sensor. A first end of the second actuating arm is used to connect to the image sensor. The second actuating arm deforms when energized, causing the image sensor to move along a second direction, which is parallel to the photosensitive surface of the image sensor and intersects with the first direction.

[0007] In this application, the image sensor can be moved along the first and second directions by the deformation of the first and second actuator arms. That is, the image sensor can be translated in the plane where the photosensitive surface is located by the first and second actuator arms, thereby realizing the smooth movement of the image sensor and realizing the image stabilization design of the camera module. This effectively avoids the image rotation problem caused by the rotating prism / reflector to achieve image stabilization and improves the imaging quality.

[0008] In this application, the image sensor is moved by the deformation of the first and second actuator arms to achieve image stabilization of the camera module. This eliminates the need for a drive motor composed of magnets and coils, reducing the overall mass and size of the motor, thus enabling image stabilization within a small space and minimizing electromagnetic interference. Furthermore, since image stabilization does not require a drive motor composed of magnets and coils, the architecture of the image stabilization solution is extremely simple, significantly reducing the number of motor parts and thus lowering motor costs.

[0009] In some possible implementations, the frame includes a first frame and a second frame. The second end of a first actuating arm is fixedly connected to the first frame, and the first actuating arm is used to move the image sensor relative to the first frame along a first direction. The first end of a second actuating arm is fixedly connected to the first frame, and the second end of the second actuating arm is fixedly connected to the second frame, and the second actuating arm is used to move the first frame, the first actuating arm, and the image sensor together relative to the second frame along a second direction.

[0010] In this implementation, by designing a first frame and a second frame, the second actuator arm can drive the first frame, the first actuator arm, and the image sensor as a whole to move together along the second direction, while the first actuator arm can drive the image sensor to move along the first direction. This makes the movement of the image sensor in the first direction and the movement in the second direction relatively independent. That is, the movement of the image sensor by the first actuator arm along the first direction and the movement of the image sensor by the second actuator arm along the second direction do not interfere with each other. This can improve the quality of the translation of the image sensor in the first direction and the translation in the second direction, thereby improving the image stabilization effect.

[0011] In some possible implementations, the first frame includes a first part and a third part, the first part and the third part of the first frame are arranged opposite each other along a first direction, and a first space is formed between the first part and the third part of the first frame. There are two first actuating arms, located in the first space, with the second end of one first actuating arm fixedly connected to the first part of the first frame, and the second end of the other first actuating arm fixedly connected to the third part of the first frame.

[0012] In this implementation, the stability of the image sensor's movement along the first direction can be improved by setting two first actuation arms. Furthermore, the coordinated movement of the two first actuation arms increases the driving force for the image sensor's movement along the first direction, thereby improving the efficiency of driving the image sensor's movement along the first direction.

[0013] In some possible implementations, the first frame further includes a second portion, which is fixedly connected between the first portion and the third portion of the first frame. The second frame includes a first portion, located on the side of the second portion of the first frame facing away from the first space. A second actuating arm is located between the first portion and the second portion of the first frame, with both ends of the second actuating arm fixedly connected to the first portion of the second frame and the second portion of the first frame, respectively.

[0014] In this implementation, the first part, the second part, and the third part of the first frame can form an "I"-shaped structure or a "C"-shaped structure to make the structure of the first frame more stable. Since the second part of the first frame is located in the middle region of the first frame in the first direction, the first end of the second actuating arm can be connected to the middle region of the first frame in the first direction, which helps to improve the stability of the second actuating arm driving the first frame as a whole to move in the second direction, and thus helps to improve the stability of the image sensor moving in the second direction.

[0015] In this implementation, the second actuating arm is disposed between the second part of the first frame and the first part of the second frame, such that the first part of the second frame, the second actuating arm, and the second part of the first frame are arranged sequentially along the second direction. Since the second actuating arm is used to drive the first frame to move along the second direction, the arrangement of the first part of the second frame, the second actuating arm, and the second part of the first frame is beneficial for the second actuating arm to drive the first frame to move along the second direction with the first part of the second frame as support, and also makes the space occupied by the first part of the second frame, the second actuating arm, and the second part of the first frame small, which is beneficial for the overall miniaturization design of the motor.

[0016] The first end of the second actuator arm can be fixedly connected to the center of the second part of the first frame in the first direction to further improve the stability of the second actuator arm driving the first frame to move in the second direction, thereby further improving the stability of the image sensor moving in the second direction.

[0017] In some possible implementations, the first rack further includes a fourth part, which is fixedly connected to the first part and the third part of the first rack and is located on one side of the first and third parts of the first rack. The second rack further includes a second part, which is connected to one side of the first part of the second rack and is located on the side of the fourth part of the first rack facing away from the first space. The second part of the second rack is slidably connected to the fourth part of the first rack.

[0018] In this implementation, the fourth part of the first frame is located on one side of the first part and the third part of the first frame, which can further improve the overall structural stability of the first frame. The second part of the second frame and the fourth part of the first frame can be slidably connected by a sliding structure, so that the second actuator arm deforms after being energized, causing the first frame to slide relative to the second frame in a second direction. Since the second part of the second frame and the fourth part of the first frame are slidably connected by a sliding structure, the second frame can provide structural support for the first frame, which is beneficial to the stability of the movement of the first frame relative to the second frame.

[0019] In some possible implementations, the motor also includes a first transmission component located in a first space, with two first actuating arms fixedly connected to its two ends, and the first transmission component is used to mount an image sensor.

[0020] In this implementation, an image sensor is mounted via a first transmission component, and two first actuating arms are fixedly connected to it. This allows the first actuating arms to move the image sensor along the first direction by driving the first transmission component to move along that direction. The first transmission component improves the connection stability between the first actuating arms and the image sensor, and avoids the structural limitations of a direct connection between the first actuating arms and the image sensor. Furthermore, since the two first actuating arms are fixedly connected to both ends of the first transmission component, the coordination and consistency of the movement of the two first actuating arms after deformation are improved, thereby enhancing the stability of moving the image sensor along the first direction.

[0021] In this embodiment, the first end of the first actuating arm can be embedded in the first transmission component to improve the connection stability between the first actuating arm and the first transmission component. In some other implementations, the first end of the first actuating arm can also be bonded to the first transmission component.

[0022] The first transmission component may include a first part, a second part, and a third part connected in sequence. The first part and the third part of the first transmission component may be arranged opposite to each other along a first direction, and the first part and the third part of the first transmission component are connected to the same side of the second part of the first transmission component. The first part of the first transmission component is fixedly connected to the first end of a first actuating arm, and the third part of the first transmission component is fixedly connected to the first end of another first actuating arm.

[0023] In this implementation, the first part, the second part and the third part of the first transmission member can form a semi-enclosed arrangement for the image sensor, which is beneficial to improving the stability of the image sensor mounted on the first transmission member. Furthermore, the arrangement of the first part and the third part of the first transmission member is beneficial to improving the stability of the first actuating arm driving the first transmission member to move along the first direction.

[0024] In some possible implementations, the motor also includes a third actuator arm, and the frame also includes a third frame. The first end of the third actuator arm is fixedly connected to the second frame, and the second end of the third actuator arm is fixedly connected to the third frame. The third actuator arm is used to deform after being energized, thereby driving the second frame to move relative to the third frame along a third direction. The third direction is perpendicular to the first direction and perpendicular to the second direction.

[0025] In some possible implementations, the third frame, the third actuator arm, and the second frame are arranged sequentially in the third direction.

[0026] In this implementation, the third actuating arm drives the second frame, the second actuating arm, the first frame, the first actuating arm, and the image sensor to move together relative to the third frame along a third direction, thereby achieving focusing of the camera module. Since the third actuating arm can move the second frame, the second actuating arm, the first frame, the first actuating arm, and the image sensor together, the movement of the third actuating arm does not interfere with the movements of the first and second actuating arms. That is, focusing and image stabilization of the camera module do not interfere with each other. For example, image stabilization can be performed during focusing, or focusing can be performed during image stabilization, and the movements of the two will not affect each other's performance.

[0027] The third frame can be part of the inner wall of the camera module housing, or the motor can be without the third frame, with the second end of the third actuator arm fixedly connected to the inner wall of the camera module housing, so that the motor can use the inner wall of the camera module housing as a support structure, which is beneficial to the miniaturization design of the camera module.

[0028] In some possible implementations, the first and second frames can be movably connected to the inner wall of the camera module housing, so that the camera module housing can provide structural support for the first and second frames, thereby improving the stability of the motor-driven translation of the image sensor.

[0029] The first frame can be connected to the inner wall of the camera module housing via a rolling structure, so that during the image stabilization compensation process, the motor can drive the first frame to move relative to the camera module housing in a second direction via the second actuator arm. Since the first frame can be connected to the inner wall of the camera module housing via the rolling structure, the camera module housing can provide structural support for the first frame when it moves in the second direction, and can also reduce the friction between the first frame and the camera module housing.

[0030] Furthermore, when the motor drives the second frame and the first frame to move together along a third direction via the third actuating arm, the first frame can move relative to the housing of the camera module along a third direction via the rolling structure. This allows the housing of the camera module to provide structural support for the first frame as it moves along the third direction, and also reduces the friction between the first frame and the housing of the camera module.

[0031] The second frame can be connected to the inner wall of the camera module housing via a sliding structure, so that the second frame can move relative to the inner wall of the camera module housing in a third direction via the sliding structure. This allows the camera module housing to provide structural support for the second frame when it moves in the third direction, and also reduces the friction between the second frame and the camera module housing.

[0032] In some possible implementations, the motor may not include a third actuator arm and a third frame; in other words, the motor has image stabilization but not focusing capabilities.

[0033] In this implementation, the motor can drive the image sensor to move in the first and second directions through the first and second actuating arms to achieve image stabilization compensation for the camera module.

[0034] The second frame can be part of the housing of the camera module.

[0035] In this implementation, since the motor only needs the first frame to move along with the image sensor during the image stabilization compensation process, and the second frame does not need to move, a portion of the camera module housing can be reused as the second frame to further simplify the motor structure and reduce the size of the motor, thereby facilitating the miniaturization design of the camera module.

[0036] The bottom wall of the camera module housing can be a second part of the second frame, and one side wall of the camera module housing can be a first part of the second frame. Specifically, the bottom wall of the camera module housing near the image sensor and the side wall that is bent and connected to the bottom wall are reused as the second and first parts of the second frame, respectively, to simplify the motor structure.

[0037] In some possible implementations, the motor further includes a first transmission member, a first rolling member, and a second rolling member. The first transmission member is used to fixably connect the image sensor. The first rolling member is connected between a first end of the first actuating arm and the first transmission member, and the second end of the first actuating arm is fixedly connected to the frame. The second rolling member is connected between a first end of the second actuating arm and the first transmission member, and the second end of the second actuating arm is fixedly connected to the frame. The second actuating arm is used to drive the image sensor to move relative to the frame in a second direction.

[0038] In this implementation, when the first actuating arm is energized and deforms, it drives the first rolling element, the first transmission element, and the image sensor to move together along the first direction. Since the first end of the second actuating arm is connected to the first transmission element through the second rolling element, the first transmission element can move relative to the second actuating arm through the rolling of the second rolling element. Similarly, when the second actuating arm is energized and deforms, it drives the second rolling element, the first transmission element, and the image sensor to move together along the second direction. Since the first end of the first actuating arm is connected to the first transmission element through the first rolling element, the first transmission element can move relative to the first actuating arm through the rolling of the first rolling element. Therefore, the design of the first and second rolling elements can reduce or even eliminate motion interference between the first and second actuating arms. In addition, the first and second actuating arms can share the same frame, eliminating the need for two nested frames, which helps reduce the size of the motor and thus facilitates the miniaturization design of the camera module.

[0039] In some possible implementations, the frame includes a first part and a second part connected together, the first part of the frame extending along a second direction and the second part of the frame extending along a first direction. The second end of a first actuating arm is fixedly connected to the first part of the frame, and the second end of a second actuating arm is fixedly connected to the second part of the frame.

[0040] In this implementation, the first part of the frame extends along the second direction, which helps reduce structural interference of the first part of the frame on the process of the second actuation arm driving the image sensor to move along the second direction. This helps to reduce the distance between the image sensor and the first part of the frame in the first direction, and thus facilitates the small-size design of the motor. The second part of the frame extends along the first direction, which helps to reduce structural interference of the second part of the frame on the process of the first actuation arm driving the image sensor to move along the first direction. This helps to reduce the distance between the image sensor and the second part of the frame in the second direction, and thus facilitates the small-size design of the motor.

[0041] In some possible implementations, the frame further includes a third part. The first part and the third part of the frame are arranged opposite each other along a first direction, and a second space is formed between the first part, the second part, and the third part of the frame. The second space accommodates a first actuating arm, a second actuating arm, a first transmission member, a first rolling member, and a second rolling member. There are two first actuating arms, one of which has its second end fixedly connected to the first part of the frame, and the other has its second end fixedly connected to the third part of the frame.

[0042] In this implementation, the first actuating arm, the second actuating arm, the first transmission component, the first rolling component, and the second rolling component are all disposed in the second space, which is beneficial for the frame to protect the first actuating arm, the second actuating arm, the first transmission component, the first rolling component, the second rolling component, and the image sensor.

[0043] In this implementation, the stability of the image sensor's movement along the first direction can be improved by setting two first actuation arms. Furthermore, the coordinated movement of the two first actuation arms increases the driving force for the image sensor's movement along the first direction, thereby improving the efficiency of driving the image sensor's movement along the first direction.

[0044] Specifically, a first preload can be present between the first actuating arm and the first transmission component. The direction of the first preload is parallel to a first direction, which can prevent the first actuating arm from detaching from the first transmission component during the movement of the image sensor, thereby improving the connection stability between the first actuating arm and the first transmission component. For example, the first preload can be achieved through magnetic attraction or elastic force.

[0045] Specifically, a second preload can be present between the second actuator arm and the first transmission member. This preload is parallel to a second direction, preventing the second actuator arm from detaching from the first transmission member during the movement of the image sensor, thereby improving the connection stability between them. For example, the second preload can be achieved through magnetic attraction or elasticity.

[0046] In some possible implementations, the first transmission member includes a first part, a second part, and a third part connected sequentially, with the first part and the third part of the first transmission member arranged opposite to each other along a first direction. The first end of one of the two first actuating arms is connected to the first part of the first transmission member via a first rolling element, and the first end of the other first actuating arm is connected to the third part of the first transmission member via another first rolling element. The first end of the second actuating arm is connected to the second part of the first transmission member via a second rolling element.

[0047] In this implementation, since the first transmission component is an integral structure, the layout of the first and second actuating arms is optimized by connecting the two first actuating arms and the second actuating arm to different parts of the first transmission component, thereby reducing motion interference between the first and second actuating arms. Furthermore, the first, second, and third parts of the first transmission component form a semi-enclosed arrangement for the image sensor, which improves the stability of mounting the image sensor on the first transmission component. The arrangement of the first and third parts of the first transmission component also improves the stability of the first actuating arm driving the first transmission component to move along the first direction.

[0048] In some possible implementations, the motor further includes a third actuating arm and a third rolling element, which are located in the second space. The first end of the third actuating arm is connected to the first transmission element via the third rolling element, and the second end of the third actuating arm is fixedly connected to the frame. The third actuating arm is used to deform when energized, driving the first transmission element and the image sensor to move relative to the frame along a third direction, which is perpendicular to the first direction and perpendicular to the second direction.

[0049] In this implementation, the third actuating arm drives the first transmission component and the image sensor to move together relative to the first frame along a third direction, thereby achieving focusing of the camera module. The first end of the first actuating arm is connected to the first transmission component via a first rolling element, and the first end of the second actuating arm is connected to the first transmission component via a second rolling element. This allows the first transmission component to move relative to the first actuating arm via the rolling of the first rolling element, and vice versa. Therefore, the design of the first and second rolling elements reduces or even eliminates motion interference between the third actuating arm and the first and second actuating arms. Thus, focusing and image stabilization of the camera module do not interfere with each other; for example, image stabilization can be performed during focusing, or focusing can be performed during image stabilization, and the movement of both will not affect each other's performance. Furthermore, the first, second, and third actuating arms can share the same frame, eliminating the need for multiple nested frames, which helps reduce the size of the motor and thus facilitates the miniaturization of the camera module.

[0050] In some possible implementations, the frame further includes a fourth part, which is fixedly connected to the first part and the third part of the frame and is located on one side of the first part and the third part of the frame. A third actuating arm is located between the fourth part of the frame and the third rolling element, and both ends of the third actuating arm are respectively connected to the fourth part of the frame and the third rolling element.

[0051] In this implementation, the third actuating arm is located between the fourth part of the frame and the third rolling member, so that the fourth part of the frame, the third actuating arm, the third rolling member and the first transmission member can be arranged in the third direction in sequence. This is beneficial for the third actuating arm to bend and deform along the third direction to drive the first transmission member to move the image sensor relative to the frame along the third direction, and it is also beneficial to improve the space utilization of the motor.

[0052] The number of third actuating arms and third rolling elements can be two. One third actuating arm is connected to the first part of the first transmission element through a third rolling element, and the other third actuating arm is connected to the third part of the first transmission element through another third rolling element.

[0053] In this implementation, by setting the two third actuator arms and the third rolling element to correspond to the first part and the third part of the first transmission element respectively, it is beneficial to balance the movement of the first transmission element driven by the third actuator arm along the third direction, thereby improving the balance of the image sensor's movement along the third direction.

[0054] Specifically, a third preload can be present between the third actuating arm and the first transmission component. This third preload is parallel to a third direction, preventing the image sensor from detaching from the third actuating arm and the first transmission component during movement, thereby improving the connection stability between them. For example, the third preload can be achieved through magnetic attraction or elasticity.

[0055] The first transmission component may further include a fourth part and a fifth part. The fourth part of the first transmission component may have a plate structure perpendicular to a third direction, and the fifth part of the first transmission component may also have a plate structure perpendicular to a third direction. The fourth part of the first transmission component is fixedly connected to the first part of the first transmission component, and is located on the side of the first part of the first transmission component closer to the fourth part of the frame. The fifth part of the first transmission component is fixedly connected to the third part of the first transmission component, and is located on the side of the third part of the first transmission component closer to the fourth part of the frame.

[0056] In this implementation, by setting the fourth and fifth parts of the first transmission member, it is beneficial to increase the contact surface between the third rolling member and the first transmission member, thereby improving the stability of the third actuating arm driving the first transmission member to move in the third direction, and thus improving the stability of the third actuating arm driving the image sensor to move in the third direction.

[0057] In some possible implementations, the frame includes a first frame, with the second end of a first actuating arm fixedly connected to the first frame, and the second end of a second actuating arm fixedly connected to the first frame. The motor also includes a second transmission member and a third transmission member spaced apart. The second transmission member is fixedly connected to the first end of the first actuating arm and has a first sliding structure extending along a second direction for connecting an image sensor. The third transmission member is fixedly connected to the first end of the second actuating arm and has a second sliding structure extending along a first direction for connecting an image sensor.

[0058] In this implementation, by setting a second sliding structure on the third transmission component, the image sensor can slide relative to the third transmission component via the second sliding structure while the first actuating arm drives the second transmission component and the image sensor to move along the first direction. This prevents the image sensor from driving the third transmission component and the second actuating arm during its movement along the first direction. Similarly, by setting a first sliding structure on the second transmission component, the image sensor can slide relative to the second transmission component via the first sliding structure while the second actuating arm drives the third transmission component and the image sensor to move along the second direction. This prevents the image sensor from driving the second transmission component and the first actuating arm during its movement along the second direction. Therefore, by setting the first and second sliding structures, movement interference between the image sensor in the first and second directions can be avoided, effectively reducing or even eliminating the hysteresis of the image sensor's movement in the first and second directions, thereby improving the smoothness of image sensor image stabilization compensation. Furthermore, the first and second actuating arms can be interchangeable with the first frame, eliminating the need for two nested frames, which helps reduce the size of the motor and thus facilitates the miniaturization design of the camera module.

[0059] The first actuating arm can be connected between the first part of the first frame and the second transmission component, and the second actuating arm can be connected between the second part of the first frame and the third transmission component.

[0060] In this implementation, the first actuating arm allows the first part of the first frame and the second transmission component to be arranged in a first direction, which facilitates the first actuating arm driving the second transmission component to move the image sensor along the first direction. Similarly, the second actuating arm allows the second part of the first frame and the third transmission component to be arranged in a second direction, which facilitates the second actuating arm driving the third transmission component to move the image sensor along the second direction.

[0061] In some possible implementations, the motor also includes a third actuator arm, and the frame also includes a third frame. The first end of the third actuator arm is fixedly connected to the first frame, and the second end of the third actuator arm is fixedly connected to the third frame. The third actuator arm is used to deform after being energized, thereby driving the first frame to move relative to the third frame along a third direction. The third direction is perpendicular to the first direction and perpendicular to the second direction.

[0062] In this implementation, the third actuator arm drives the second actuator arm, the first frame, the first actuator arm, and the image sensor to move together relative to the third frame along a third direction, thereby achieving focusing of the camera module. Since the third actuator arm can move the second actuator arm, the first frame, the first actuator arm, and the image sensor together, the movement of the third actuator arm does not interfere with the movements of the first and second actuator arms. That is, focusing and image stabilization of the camera module do not interfere with each other. For example, image stabilization can be performed during focusing, or focusing can be performed during image stabilization, and the movements of the two will not affect each other's performance.

[0063] The third actuator arm can be connected between the third frame and the fourth part of the first frame. The third frame, the third actuator arm and the fourth part of the first frame are arranged in the third direction in sequence.

[0064] In this implementation, since the third actuating arm drives the first frame to move in a third direction, the arrangement direction of the third frame, the third actuating arm, and the fourth part of the first frame is the same as the direction of movement of the first frame relative to the third frame driven by the third actuating arm. This allows the third actuating arm to deform along the third direction, thereby driving the first frame to move relative to the third frame in the third direction, which is beneficial to improving the efficiency of the third actuating arm driving the first frame.

[0065] In some possible implementations, the second frame has a third sliding structure that extends along the second direction and is connected to the first frame.

[0066] In this implementation, a third sliding structure is provided so that the second actuating arm deforms when energized, driving the first frame to move relative to the second frame along the third sliding structure. This, in turn, causes the image sensor and the first actuating arm to move together relative to the second frame in a second direction. Furthermore, when the first actuating arm deforms when energized, it drives the image sensor to move relative to the first frame in a first direction, while the first and second frames remain relatively stationary. Therefore, the design of the third sliding structure reduces or even eliminates motion interference between the first and second actuating arms.

[0067] The second rack can be connected to the first part of the first rack and the third part of the first rack, and is located on one side of the first part of the first rack and the third part of the first rack.

[0068] In this implementation, by setting the second frame to be slidably connected to both the first part of the first frame and the third part of the first frame, it is beneficial to reduce the size of the frame, thereby facilitating the miniaturization of the motor design.

[0069] In some possible implementations, the motor also includes a third actuator arm, and the frame also includes a third frame. The first end of the third actuator arm is fixedly connected to the second frame, and the second end of the third actuator arm is fixedly connected to the third frame. The third actuator arm is used to deform after being energized, thereby driving the second frame to move relative to the third frame along a third direction. The third direction is perpendicular to the first direction and perpendicular to the second direction.

[0070] In this implementation, by setting up a third frame and a third actuating arm, the third actuating arm can deform after being energized, thereby moving the second frame, the second actuating arm, the first frame, the first actuating arm, and the image sensor together along a third direction, thus achieving focusing of the camera module. Since the third actuating arm can move the second frame, the second actuating arm, the first frame, the first actuating arm, and the image sensor together, the movement of the third actuating arm does not interfere with the movements of the first and second actuating arms. That is, focusing and image stabilization of the camera module do not interfere with each other; for example, image stabilization can be performed during focusing, or focusing can be performed during image stabilization, and the movements of the two will not affect each other's performance.

[0071] In some possible implementations, the third frame, the third actuator arm, and the second frame are arranged sequentially in the third direction.

[0072] In this implementation, since the third actuating arm drives the second frame to move in a third direction, the arrangement of the third frame, the third actuating arm, and the second frame is the same as the direction in which the third actuating arm drives the second frame to move relative to the third frame. This allows the third actuating arm to deform along the third direction, thereby enabling the second frame to move relative to the third frame in the third direction, which is beneficial to improving the efficiency of the third actuating arm driving the second frame.

[0073] In some possible implementations, both the first and second actuating arms include piezoelectric materials.

[0074] In this implementation, both the first and second actuating arms can include piezoelectric materials. This allows the first and second actuating arms to deform at their ends using the piezoelectric effect after being energized. This results in greater displacement and thrust from the first and second actuating arms, and enables higher-frequency deformation, which is beneficial for achieving large-angle and high-frequency image stabilization in the camera module. Furthermore, since using piezoelectric materials allows for the design of both the first and second actuating arms, there is no need for a drive motor composed of magnets and wound coils. This reduces the overall mass and size of the motor, enabling image stabilization within a smaller space and reducing electromagnetic interference. Moreover, because image stabilization does not require a drive motor composed of magnets and coils, the image stabilization architecture is extremely simple, significantly reducing the number of motor parts and thus lowering motor costs.

[0075] The third actuation arm can include piezoelectric materials, allowing it to deform at its end using the piezoelectric effect when energized. This results in a larger displacement and thrust, and enables higher frequency deformation, which is beneficial for rapid focusing of the camera module. Furthermore, since the third actuation arm can be designed using piezoelectric materials, there is no need for a drive motor composed of magnets and wound coils. This reduces the overall mass and size of the motor, allowing focusing to be achieved in a smaller space and minimizing electromagnetic interference.

[0076] In some possible implementations, the first actuating arm has a plate-like structure, and the plate surface of the first actuating arm is perpendicular to the first direction.

[0077] In this implementation, the first actuating arm can be a plate-like structure, with its plate surface perpendicular to the first direction. This allows the end of the first actuating arm connected to the image sensor to warp along the first direction, thereby enabling the image sensor to move along the first direction and improving the efficiency of this movement. Furthermore, the plate-like structure of the first actuating arm reduces the space it occupies in the first direction, improving the space utilization of the motor and reducing its size. Additionally, the plate-like structure of the first actuating arm increases the contact area between the first actuating arm and the image sensor, thus improving the motion stability of the image sensor.

[0078] The first actuator arm can have a bent or curved structure, which is beneficial to increase the total length of the first actuator arm in the same space. This allows the first end of the first actuator arm to undergo greater deformation after being powered on, thereby driving the image sensor to achieve greater displacement and improving the image stabilization capability of the camera module.

[0079] In some possible implementations, the second actuator arm has a plate-like structure, with the plate surface of the second actuator arm perpendicular to the second direction.

[0080] In this implementation, the second actuating arm can be a plate-like structure, with its plate surface perpendicular to the second direction. This allows the end of the second actuating arm connected to the image sensor to warp along the second direction, thereby enabling the image sensor to move along the second direction and improving the efficiency of this movement. Furthermore, the plate-like structure of the second actuating arm reduces the space it occupies in the second direction, improving the space utilization of the motor and reducing its size. Additionally, the plate-like structure of the second actuating arm increases the contact area between the second actuating arm and the image sensor, thus improving the motion stability of the image sensor.

[0081] The second actuator arm can have a bent or curved structure, which helps to increase the total length of the second actuator arm in the same space. This allows the first end of the second actuator arm to undergo greater deformation after being powered on, thereby driving the image sensor to achieve greater displacement and improving the image stabilization capability of the camera module.

[0082] In some possible implementations, the third actuating arm may be a plate-like structure, and the plate surface of the third actuating arm may be perpendicular to the third direction.

[0083] In this implementation, the third actuating arm can be a plate-like structure, with its plate surface perpendicular to a third direction. This allows the end of the third actuating arm connecting to the second frame to warp along the third direction, thereby enabling the second frame to move along that direction and improving the efficiency of this movement. Furthermore, the plate-like structure of the third actuating arm reduces the space it occupies in the third direction, improving the space utilization of the motor and reducing its size. Additionally, the plate-like structure of the third actuating arm increases the contact area between the third actuating arm and the second frame, thus improving the motion stability of the image sensor.

[0084] The third actuator arm can have a bent or curved structure, which is beneficial to increase the total length of the third actuator arm in the same space. This allows the first end of the third actuator arm to undergo greater deformation after being powered on, thereby driving the image sensor to achieve greater displacement and improving the image stabilization capability of the camera module.

[0085] In some possible implementations, the motor also includes a position detection component for detecting the position of the image sensor.

[0086] In this implementation, by setting a position detection component, the position of the image sensor can be detected, so that during the image stabilization process, the position detection component can provide real-time feedback on the position of the image sensor, which helps to improve the motion accuracy of the image sensor and thus improve the image stabilization effect.

[0087] The position detection component may include a magnet and a magnetic sensor. The magnet may be fixedly mounted on a first part and / or a third part of the first transmission member. The magnetic sensor may be fixedly mounted on a first part and / or a third part of the first frame and electrically connected to a conductive wire. The magnet and the magnetic sensor are positioned opposite each other.

[0088] In this implementation, the change in the magnetic field between the magnet and the magnetic sensor can be detected by the relative position between the magnet and the magnetic sensor, thereby detecting the position information of the image sensor.

[0089] The magnet can be embedded in the first transmission component to improve the installation stability of the magnet and save installation space.

[0090] In some possible implementations, the magnet and the magnetic sensor can be positioned opposite each other along a direction perpendicular to the first direction. In this case, the position of the image sensor relative to the first frame can be determined based on the area of ​​the region where the magnet and the magnetic sensor face each other. The stronger the magnetic field between the magnet and the magnetic sensor, the larger the area of ​​the region where they face each other.

[0091] In some other possible implementations, the magnet and the magnetic sensor can be positioned relative to each other along a first direction. In this case, the position of the image sensor relative to the first frame can be determined based on the relative distance between the magnet and the magnetic sensor. The stronger the magnetic field between the magnet and the magnetic sensor, the smaller the distance between them.

[0092] In some possible implementations, the position detection component can be a single unit. The position of the image sensor relative to the frame can be detected by the relative position of the magnet and the magnetic sensor within the position detection component. Specifically, the magnetic sensor can be mounted on the frame, and the magnet can be mounted on the first transmission component, with the magnetic sensor and magnet facing each other. During movement, the image sensor changes the size, area, and spacing of the parts of the magnet and magnetic sensor facing each other, causing a change in the magnetic field between them. The position of the image sensor is then determined based on this change in the magnetic field.

[0093] In some other possible implementations, the number of position detection components can be set to multiple to improve the position detection accuracy of the image sensor.

[0094] Secondly, this application provides a camera module. The camera module includes a housing, a lens, an image sensor, and a motor as implemented in any of the foregoing embodiments, wherein the lens, image sensor, and motor are mounted on the housing.

[0095] In this application, a motor drives the image sensor to translate along a first and a second direction, i.e., along the X and Y directions, to compensate for camera module shake. This avoids rotation of the first optical element and the image sensor during image stabilization, thereby reducing or even eliminating image rotation problems and improving the image quality of the image sensor. The motor also drives the image sensor to translate along a third direction, i.e., along the Z direction, to change the focal length of the lens, thus achieving focusing of the camera module. Since focusing can be achieved simply by driving the image sensor to translate with a motor, the focusing structure at the lens group can be reduced or even eliminated, simplifying the focusing structure of the camera module. Furthermore, since driving the image sensor to translate with a motor achieves both image stabilization and focusing, the image stabilization and focusing structures are integrated into a single design, simplifying the structural design of the camera module and facilitating miniaturization.

[0096] In some possible implementations, the motor can be arranged around the periphery of the lens portion to reduce the space occupied by the motor in the camera module.

[0097] In some possible implementations, the lens may include a first optical element, a lens group, and a second optical element. The first optical element, the lens group, and the second optical element are arranged sequentially at intervals along the optical path of the camera module. An image sensor is disposed on the image side of the second optical element, and the photosensitive surface of the image sensor is parallel to the optical axis of the lens group. A motor may be arranged around the periphery of the second optical element.

[0098] In this implementation, the motor can be arranged in a semi-enclosed structure around the second optical element, so that the motor can be designed to mimic the shape and structure of the second optical element. By utilizing the space gap around the second optical element, the extra space occupied by the motor in the camera module can be reduced, thereby improving the space utilization of the camera module and facilitating the miniaturization of the camera module.

[0099] In some other possible implementations, the lens may not include a second optical element, the image sensor may be located on the image side of the lens group, and the photosensitive surface of the image sensor may be perpendicular to the optical axis of the lens group. The motor may be arranged around the periphery of a portion of the lens group to reduce the space occupied by the motor in the camera module.

[0100] In this implementation, the motor can utilize the peripheral space of the lens group, which can save space. Furthermore, the frame structure in the motor can reuse the lens barrel structure of the lens group, further reducing the space occupied by the motor and facilitating the miniaturization of the camera module.

[0101] Furthermore, the motor can utilize the camera module's housing as part of its frame, thus reusing the camera module's housing structure and further reducing the space occupied by the motor. For example, the motor can use part of the camera module's housing structure as its own housing or base.

[0102] Thirdly, this application provides an electronic device. The electronic device includes a housing and a camera module as implemented in any of the foregoing embodiments, the camera module being mounted on the housing.

[0103] In this application, both image stabilization and focusing can be achieved by driving the image sensor to translate using a motor. This integrates the image stabilization and focusing structures, simplifies the structural design of the camera module, and facilitates the miniaturization of the camera module, thereby enabling the thinner and lighter design of electronic devices.

[0127] The embodiments of this application are described below with reference to the accompanying drawings.

[0128] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. "Multiple" refers to at least two.

[0129] The directional terms mentioned in the embodiments of this application, such as "upper", "lower", "inner", "outer", "top", "bottom", "side", etc., are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this application, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application.

[0130] In the embodiments of this application, the relative positional relationships mentioned, such as parallel, perpendicular, and aligned, are defined in relation to the current technological level, rather than being absolutely strict. Slight deviations are permissible; approximations of parallelism, perpendicularity, or alignment are all acceptable. For example, "A and B are parallel" means that A and B are parallel or approximately parallel, and the angle between A and B can be between 0 and 10 degrees. Similarly, "A and B are perpendicular" means that A and B are perpendicular or approximately perpendicular, and the angle between A and B can be between 80 and 100 degrees.

[0131] In the embodiments of this application, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," "third," and "fourth" may explicitly or implicitly include one or more of that feature.

[0132] Please refer to Figures 1A and 1B. Figure 1A is a schematic diagram of the structure of the electronic device 1000 provided in some embodiments of this application; Figure 1B is a partially exploded schematic diagram of the electronic device 1000 shown in Figure 1A.

[0133] In some embodiments, the electronic device 1000 can be a mobile phone, tablet personal computer, laptop computer, smart screen, personal digital assistant (PDA), camera, personal computer, laptop computer, in-vehicle equipment, wearable device, augmented reality (AR) glasses, AR headset, virtual reality (VR) glasses, or VR headset, or other devices with camera functionality. In the embodiment shown in Figure 1A, the electronic device 1000 is described as a mobile phone; however, other types of electronic devices 1000 can also adopt similar structures, which will not be elaborated upon further below.

[0134] It is understood that Figures 1A and 1B only schematically show some of the components included in the electronic device 1000. The actual shape, size, location and construction of these components are not limited by Figures 1A and 1B. The electronic device 1000 may also include more or fewer components than those in Figures 1A and 1B.

[0135] In some embodiments, the electronic device 1000 may include a camera module 100, a screen 200, and a housing 300. The screen 200 is used to display images, videos, etc. The screen 200 may include a light-transmitting panel 2001 and a display screen 2002. The light-transmitting panel 2001 and the display screen 2002 are stacked and fixedly connected. The light-transmitting panel 2001 mainly serves to protect the display screen 2002 from dust. The material of the light-transmitting panel 2001 includes, but is not limited to, glass. The display screen 2002 may be a flexible display screen or a rigid display screen. For example, the display screen 2002 can be an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode (AMOLED) display screen, a mini organic light-emitting diode (MLED) display screen, a micro organic light-emitting diode (MOLED) display screen, a quantum dot light-emitting diode (QLED) display screen, a liquid crystal display (LCD), etc.

[0136] For example, the housing 300 is used to protect the internal electronic components of the electronic device 1000. The housing 300 may include a cover plate 3001, a frame 3002, and a camera trim 3003. The cover plate 3001 is located on the side of the display screen 2002 away from the light-transmitting panel 2001, and is stacked with the light-transmitting panel 2001 and the display screen 2002. The frame 3002 is fixed to the cover plate 3001. For example, the frame 3002 can be fixedly connected to the cover plate 3001 by adhesive. The frame 3002 may also be integrally formed with the cover plate 3001, that is, the frame 3002 and the cover plate 3001 are a single structure. The frame 3002 is located between the cover plate 3001 and the light-transmitting panel 2001. The light-transmitting panel 2001 can be fixed to the frame 3002 by adhesive. The light-transmitting panel 2001, the cover plate 3001, and the frame 3002 form an internal accommodating space for the electronic device 1000. The internal space houses the display screen 2002. The cover plate 3001 can be made of materials such as metal, plastic, or glass. The cover plate 3001 can be a single-material panel or a panel structure composed of multiple materials and panels. The cover plate 3001 has a mounting opening, and the camera decorative piece 3003 covers and is fixed to the mounting opening.

[0137] For example, camera module 100 is used to capture photos / videos. For example, camera module 100 is mounted within housing 300, located within the internal accommodating space of electronic device 1000. Camera module 100 can be used as a rear-facing camera. For example, the light-incident surface of camera module 100 faces camera trim 3003. Camera trim 3003 is used to protect camera module 100.

[0138] In some embodiments, the camera trim 3003 protrudes from the side of the cover plate 3001 away from the light-transmitting panel 2001. This increases the mounting space for the camera module 100 in the thickness direction of the electronic device 1000. In other embodiments, the camera trim 3003 may be flush with the cover plate 3001 or recessed into the internal accommodating space of the electronic device 1000.

[0139] The camera decorative element 3003 has a through hole 3004. The through hole 3004 allows light from objects to enter the light-receiving surface of the camera module 100. In some other embodiments, the electronic device 1000 may not include the camera decorative element 3003. In this case, the cover plate 3001 no longer has a mounting opening, but the through hole 3004 is provided on the cover plate 3001, allowing light from objects to enter the light-receiving surface of the camera module 100.

[0140] In some embodiments, the camera module 100 can also be used as a front-facing camera. For example, the light-incident surface of the camera module 100 faces the light-transmitting panel 2001. The display screen 2002 is provided with a light-path obstruction hole. This light-path obstruction hole allows light from the scene to pass through the light-transmitting panel 2001 and then enter the light-incident surface of the camera module 100. In some embodiments, the electronic device 1000 may also include one or more other camera modules (not shown in the figures), which are not strictly limited in this application.

[0141] In some embodiments, as shown in FIG1B, the electronic device 1000 may further include a circuit board 400 and an image processor 500. The circuit board 400 and the image processor 500 are located within the internal accommodating space of the electronic device 1000. The image processor 500 is fixed to the circuit board and electrically connected to the circuit board 400. The image processor 500 is communicatively connected to the camera module 100. The image processor 500 is used to acquire image data from the camera module 100 and process the image data. The communication connection between the camera module 100 and the image processor 500 may include data transmission via electrical connections such as wiring, or data transmission may be achieved through coupling or other methods. It is understood that the camera module 100 and the image processor 500 may also achieve a communication connection through other methods capable of data transmission.

[0142] In some embodiments, the electronic device 1000 may further include an analog-to-digital converter (also known as an A / D converter, not shown in the figure). The analog-to-digital converter is connected between the camera module 100 and the image processor 500. The analog-to-digital converter is used to convert the signal generated by the camera module 100 into a digital image signal and transmit it to the image processor 500, whereby the image processor 500 processes the digital image signal and finally displays the image or video on the screen 200.

[0143] In some embodiments, the electronic device 1000 may further include a memory (not shown in the figure), which is communicatively connected to the image processor 500. The image processor 500 processes the digital image signal and then transmits the image to the memory, so that the image can be retrieved from the memory and displayed on the screen 200 at any time when it is needed to view the image later. In some embodiments, the image processor 500 may also compress the processed digital image signal before storing it in the memory to save memory space.

[0144] In some other embodiments, the electronic device 1000 may also not include the screen 200.

[0145] It is understood that the mounting position of the camera module 100 in the electronic device 1000 of the embodiments shown in Figures 1A and 1B is merely illustrative, and this application does not strictly limit the mounting position of the camera module 100. In some other embodiments, the camera module 100 may also be mounted in other locations on the electronic device 1000, for example, the camera module 100 may be mounted in the upper middle or upper right corner of the back of the electronic device 1000. In some other embodiments, the electronic device 1000 may include a terminal body and an auxiliary component that can rotate, move, or be detached relative to the terminal body, and the camera module 100 may also be disposed on the auxiliary component.

[0146] Please refer to Figures 2A and 2B. Figure 2A is a schematic diagram of the structure of the camera module 100 provided in this application in some embodiments; Figure 2B is a schematic diagram of the structure of the camera module 100 provided in this application in other embodiments.

[0147] In some embodiments, the camera module 100 may include a motor 10, a lens 20, an image sensor 30, and a housing (not shown in the figure). The housing may house the motor 10, the lens 20, and the image sensor 30. The image sensor 30 is located on the optical axis of the lens 20, that is, the image sensor 30 is located in the optical path of the camera module 100, and the image sensor 30 is mounted on the motor 10. It should be noted that the optical path direction of the camera module 100 is such that light enters from the outside, passes through the lens 20, and then enters the image sensor 30, which is illustrated by a dashed line with an arrow in Figure 2A.

[0148] In some examples, referring to Figure 2A, the lens 20 may include a first optical element 201, a lens group 202, and a second optical element 203. The first optical element 201, lens group 202, and second optical element 203 are sequentially arranged at intervals along the optical path of the camera module 100. An image sensor 30 is disposed on the image side of the second optical element 203, and the photosensitive surface of the image sensor 30 is parallel to the optical axis of the lens group 202.

[0149] The first optical element 201 is used to receive external light and change the transmission direction of the external light so that the light can pass through the lens group 202. The second optical element 203 is used to receive the light passing through the lens group 202 and change the transmission direction of the light passing through the lens group 202 so that the light can be incident on the image sensor 30.

[0150] For example, the first optical element 201 is used to receive external light and fold the optical path of the received light before transmitting it to the lens group 202, thus realizing optical path folding, also known as optical path reversal, which refers to changing the transmission path of light. For example, the first optical element 201 can be a prism (e.g., a right-angle prism or a triangular prism) or a reflective element such as a mirror. In some other embodiments, the first optical element 201 may also be referred to as an optical folding element.

[0151] For example, the second optical element 203 is used to fold the light path of the light transmitted through the lens group 202 and transmit it to the image sensor 30, realizing optical path folding, also known as optical path reversal, which refers to changing the transmission path of light. For example, the second optical element 203 can be a prism (e.g., a right-angle prism or a triangular prism) or a reflective element such as a mirror. In some other embodiments, the second optical element 203 may also be referred to as an optical folding element.

[0152] For example, the lens group 202 is used to transmit the light reflected by the first optical element 201 to the second optical element 203, and refract the light to the image sensor 30 through the second optical element 203, thereby imaging the scene on the object side onto the photosensitive surface on the image side. Here, the object side refers to the side where the subject is located, and the image side is the side where the image of the subject is located. The lens group 202 can also perform certain processing on the light reflected by the first optical element 201, such as aberration correction and chromatic aberration reduction.

[0153] The lens group 202 may include at least one lens (or lens element), which may be different or the same. In this embodiment, the number of lenses and lens materials included in the lens group 202 are not specifically limited. The number of lenses can be set according to actual needs, or a combination of solid lenses (with fixed lens parameters) and / or liquid lenses (with dynamically adjustable lens parameters) can be used. Further details are omitted here.

[0154] The lens group 202 may further include a lens barrel for accommodating at least one lens. To achieve zoom, the lens barrel may be a single unit, with at least one lens housed within it, but the relative positions of the lenses can be adjusted using other structures. Alternatively, the lens barrel may comprise multiple lens barrel sections, with at least one lens grouped within each section, and the relative positions of the multiple lens barrel sections can be adjusted to achieve adjustment of the relative positions of the lenses.

[0155] For example, the image sensor 30 is disposed on the image side of the second optical element 203 and is mainly used for imaging. Specifically, the image sensor 30 has an image acquisition area (also called a photosensitive area or photosensitive surface), through which the image sensor 30 acquires the received light. The image sensor 30 is a device with photoelectric conversion function, capable of converting the light signal acquired on the image acquisition area into an electrical signal proportional to the light signal. The image sensor 30 can be a CCD image sensor composed of a charge-coupled device (CCD) or a CMOS image sensor composed of a complementary metal oxide semiconductor (CMOS).

[0156] The first optical element 201, lens group 202, second optical element 203, and image sensor 30 are arranged sequentially along the optical path. The imaging principle of the camera module 100 is as follows: light entering the camera module 100 from the object side is refracted by the first optical element 201, the refracted light is projected onto the second optical element 203 through the lens group 202, and the second optical element 203 refracts the received light onto the image sensor 30 to achieve imaging of the object.

[0157] In some embodiments, the camera module 100 may also include a filter (e.g., an infrared cut-off filter (IRCF) or a filter that filters out other light bands) disposed between the lens group 202 and the image sensor 30. For example, when the filter is an IRCF, unwanted light projected onto the image sensor 30 can be eliminated, preventing problems such as ghosting, stray light, and color cast from occurring during image formation.

[0158] In some embodiments, the first optical element 201 can be made of a material with near-infrared absorption characteristics, such as blue glass or resin-based absorbing materials, or colorless glass coated with absorbing materials, to achieve near-infrared cutoff capability of the camera module 100. Alternatively, the first optical element 201 can be made of white glass, and at least one surface used for light transmission can be covered with a near-infrared cutoff film to achieve near-infrared cutoff capability of the camera module 100.

[0159] In other embodiments, the camera module 100 may also include connectors, circuit boards, and peripheral electronic components, which will not be described in detail here.

[0160] In some other examples, see Figure 2B, the lens 20 may not include the second optical element 203, the image sensor 30 may be located on the image side of the lens group 202, and the photosensitive surface of the image sensor 30 may be perpendicular to the optical axis of the lens group 202.

[0161] For ease of description, the direction perpendicular to the photosensitive surface of the image sensor 30 is defined as the Z direction (e.g., the vertical direction of the paper shown in Figure 2A, or the horizontal direction of the paper shown in Figure 2B, also referred to as the Z-axis direction). The direction parallel to the photosensitive surface of the image sensor 30, and in the embodiment of Figure 2A, parallel to the optical axis of the lens group 202, is defined as the X direction (in the embodiment of Figure 2B, the X direction is parallel to the direction in which light rays are incident on the first optical element 201, also referred to as the X-axis direction). The direction perpendicular to both the X and Z directions is defined as the Y direction (e.g., the direction perpendicular to the paper shown in Figure 2A, also referred to as the Y-axis direction). More specifically, the direction of the Z-axis toward the image side is defined as the positive direction of the Z-axis, and the direction of the Z-axis away from the image side is defined as the negative direction of the Z-axis. In the XZ plane, the positive direction of the X-axis is the direction of counterclockwise rotation of the positive direction of the Z-axis, and the negative direction of the X-axis is the direction of clockwise rotation of the positive direction of the Z-axis. In the YZ plane, the positive direction of the Y-axis is the direction of clockwise rotation of the positive direction of the Z-axis, and the negative direction of the Y-axis is the direction of counterclockwise rotation of the positive direction of the Z-axis. Similarly, the definitions of the X, Y, and Z directions also apply to the figures described below. It should be noted that the above definitions of the X, Y, and Z directions are merely for the convenience of describing the positional and connection relationships between the components in the embodiments of this application and should not be construed as limiting the embodiments of this application.

[0162] It should be noted that, for ease of description, the Y direction can also be called the first direction D1, the X direction can also be called the second direction D2, and the Z direction can also be called the third direction D3.

[0163] Please refer to Figures 2B and 3. Figure 3 is a schematic diagram of the camera module shown in Figure 2B implementing image stabilization and focusing in some embodiments.

[0164] To reduce image blur caused by camera shake during shooting and improve image quality, the camera module 100 generally has optical image stabilization. For the camera module 100, the first optical element 201 is usually rotated by a motor to compensate for shake. However, the rotation of the first optical element 201 can easily cause image rotation problems in the image sensor 30.

[0165] To address the image rotation problem of the camera module 100 during image stabilization, this application provides a novel motor design.

[0166] In some embodiments, the image sensor 30 can be mounted on the motor 10, which can drive the image sensor 30 to translate along a first direction D1 and a second direction D2, thereby achieving image stabilization of the camera module 100. The first direction D1 and the second direction D2 are both parallel to the photosensitive surface of the image sensor 30, and the first direction D1 and the second direction D2 intersect. It should be noted that the first direction D1 can be perpendicular to the second direction D2.

[0167] In this embodiment, the image sensor 30 is translated along the first direction D1 and the second direction D2 by the motor 10, that is, the image sensor 30 is translated along the X and Y directions to achieve shake compensation of the camera module 100, avoid the rotation of the first optical element 201 and the image sensor 30 during the image stabilization process, thereby reducing or even avoiding image rotation problem and improving the imaging quality of the image sensor 30.

[0168] In some embodiments, the motor 10 can also drive the image sensor 30 to translate along a third direction D3 to achieve focusing of the camera module 100.

[0169] In this embodiment, the image sensor 30 is translated along the third direction D3 by the motor 10, that is, the image sensor 30 is translated along the Z direction, thereby changing the focal length of the lens 20 and achieving focusing of the camera module 100. Since focusing can be achieved by driving the image sensor 30 to translate by the motor 10, the focusing structure at the lens group 202 can be reduced or even eliminated, thus simplifying the focusing structure of the camera module 100. In addition, since driving the image sensor 30 to translate by the motor 10 can achieve both image stabilization and focusing, the image stabilization structure and the focusing structure are integrated into a single design, simplifying the structural design of the camera module 100 and facilitating the miniaturization of the camera module 100, thereby achieving a thinner and lighter design of the electronic device 1000.

[0170] The following is a detailed description of the camera module 100 shown in Figure 2A.

[0171] Please refer to Figures 4A and 4B. Figure 4A is a three-dimensional structural schematic diagram of the camera module 100 shown in Figure 2A in some embodiments; Figure 4B is a partial structural exploded schematic diagram of the camera module 100 shown in Figure 4A in some embodiments.

[0172] In some embodiments, the motor 10 may be arranged around a portion of the lens 20 to reduce the space occupied by the motor 10 in the camera module 100.

[0173] For example, the motor 10 can be arranged around the periphery of the second optical element 203. Specifically, the motor 10 can be arranged in a semi-enclosed structure around the second optical element 203, so that the motor 10 can be designed to conform to the shape and structure of the second optical element 203, and the space gap around the second optical element 203 can be used to reduce the extra space occupied by the motor 10 in the camera module 100, thereby improving the space utilization of the camera module 100 and facilitating the miniaturization design of the camera module 100.

[0174] Furthermore, the motor 10 can utilize the housing of the camera module 100 to reuse the housing structure of the camera module 100, thereby further reducing the space occupied by the motor 10. For example, the motor 10 can use part of the housing structure of the camera module 100 as its own housing or base.

[0175] It should be noted that during the process of driving the image sensor 30 to translate, the motor 10 does not drive the second optical element 203 to move, that is, there is no motion connection between the motor 10 and the second optical element 203.

[0176] Please refer to Figures 5A to 5C. Figure 5A is a structural schematic diagram of the motor 10 in the camera module 100 shown in Figure 4A in some embodiments; Figure 5B is a partially exploded structural schematic diagram of the motor 10 shown in Figure 5A in some embodiments; Figure 5C is a structural schematic diagram of the motor 10 shown in Figure 5A from another perspective. It should be noted that, for ease of description, the second actuating arm 3 and the third actuating arm 8 in Figure 5C are marked with a grid. The grid is only used to highlight the second actuating arm 3 and the third actuating arm 8 and is not a cross-sectional structure.

[0177] In some embodiments, the motor 10 may include a frame 1, a first actuating arm 2, and a second actuating arm 3, both of which are mounted on the frame 1. Both the first actuating arm 2 and the second actuating arm 3 are connected to an image sensor 30. The first actuating arm 2 deforms upon being energized, causing the image sensor 30 to move along a first direction D1. The second actuating arm 3 deforms upon being energized, causing the image sensor 30 to move along a second direction D2.

[0178] It should be noted that the connection between the first actuator arm 2 and the second actuator arm 3 and the image sensor 30 can be direct or indirect, and no limitation is made here.

[0179] In this embodiment, the image sensor 30 can be moved along the first direction D1 and the second direction D2 by the deformation of the first actuator arm 2 and the second actuator arm 3. That is, the image sensor 30 can be translated in the plane where the photosensitive surface is located by the first actuator arm 2 and the second actuator arm 3, thereby realizing the smooth movement of the image sensor 30 and realizing the image stabilization design of the camera module 100. This effectively avoids the image rotation problem caused by the rotating prism / reflector to achieve image stabilization and improves the imaging quality.

[0180] Both the first actuating arm 2 and the second actuating arm 3 can include piezoelectric materials, allowing them to deform at their ends using the piezoelectric effect after being energized. This results in greater displacement and thrust from the first and second actuating arms 2 and 3, and enables higher frequency deformation, which is beneficial for the camera module 100 to achieve large-angle and high-frequency image stabilization. Furthermore, since the first and second actuating arms 2 and 3 can be designed using piezoelectric materials, there is no need for a drive motor composed of magnets and wound coils. This reduces the overall weight and size of the motor 10, allowing for image stabilization within a smaller space and reducing electromagnetic interference. Moreover, because image stabilization does not require a drive motor composed of magnets and coils, the image stabilization architecture is extremely simple, significantly reducing the number of parts in the motor 10 and thus lowering its cost.

[0181] The first actuating arm 2 can be plate-shaped, with its plate surface perpendicular to the first direction D1. This allows the end of the first actuating arm 2 connected to the image sensor 30 to warp along the first direction D1, thereby enabling the image sensor 30 to move along the first direction D1 and improving the efficiency of this movement. Furthermore, the plate-shaped structure of the first actuating arm 2 reduces the space occupied by it along the first direction D1, improving the space utilization of the motor 10 and reducing its overall size. Additionally, the plate-shaped structure of the first actuating arm 2 increases the contact area between it and the image sensor 30, thus improving the motion stability of the image sensor 30.

[0182] The second actuating arm 3 can be plate-shaped, with its plate surface perpendicular to the second direction D2. This allows the end of the second actuating arm 3 connected to the image sensor 30 to warp along the second direction D2, thereby enabling the image sensor 30 to move along the second direction D2 and improving the efficiency of this movement. Furthermore, the plate-shaped structure of the second actuating arm 3 reduces the space it occupies in the second direction D2, improving the space utilization of the motor 10 and reducing its overall size. Additionally, the plate-shaped structure of the second actuating arm 3 increases the contact area between the second actuating arm 3 and the image sensor 30, thus improving the motion stability of the image sensor 30.

[0183] The shape of the plate surface of the first actuator arm 2 and the second actuator arm 3 can be rectangular, "L" shaped, "I" shaped, or "C" shaped, etc., and there are no restrictions here.

[0184] The first actuator arm 2 may have a bent or curved structure, which is beneficial to increase the total length of the first actuator arm 2 in the same space. This allows the first end 21 of the first actuator arm 2 to undergo greater deformation after being powered on, thereby driving the image sensor 30 to achieve greater displacement and improving the image stabilization capability of the camera module 100.

[0185] The second actuator arm 3 may have a bent or curved structure, which is beneficial to increase the total length of the second actuator arm 3 in the same space. This allows the first end 31 of the second actuator arm 3 to undergo greater deformation after being powered on, thereby driving the image sensor 30 to achieve greater displacement and improving the image stabilization capability of the camera module 100.

[0186] The number of first actuator arms 2 can be one or more, and there is no limit to this.

[0187] The number of second actuator arms 3 can be one or more, and there is no limitation on this.

[0188] It should be noted that the first actuator arm 2 and the second actuator arm 3 can also be other shapes, such as strip, column, block, etc., which are not limited here.

[0189] In some embodiments, the frame 1 may include a first frame 101 and a second frame 102. The first actuating arm 2 may include a first end 21 and a second end 22. The first end 21 of the first actuating arm 2 may be connected to the image sensor 30, and the second end 22 of the first actuating arm 2 may be fixedly connected to the first frame 101. The second actuating arm 3 may include a first end 31 and a second end 32. The first end 31 of the second actuating arm 3 may be connected to the first frame 101, and the second end 32 of the second actuating arm 3 may be fixedly connected to the second frame 102. The second actuating arm 3 is used to drive the first frame 101, the first actuating arm 2, and the image sensor 30 to move together relative to the second frame 102 along a second direction D2.

[0190] In this embodiment, by designing a first frame 101 and a second frame 102, and by enabling the second actuator arm 3 to drive the first frame 101, the first actuator arm 2, and the image sensor 30 to move together along the second direction D2, the movement of the image sensor 30 in the first direction D1 and the movement in the second direction D2 are relatively independent. That is, the movement of the image sensor 30 driven by the first actuator arm 2 along the first direction D1 and the movement of the image sensor 30 driven by the second actuator arm 3 along the second direction D2 do not interfere with each other. This can improve the quality of the translation of the image sensor 30 in the first direction D1 and the translation in the second direction D2, thereby improving the image stabilization effect.

[0191] For example, the first rack 101 may include a first portion 101a, a second portion 101b, a third portion 101c, and a fourth portion 101d. The first portion 101a and the third portion 101c of the first rack 101 are disposed opposite to each other along a first direction D1, forming a first space 1011 between them. The second portion 101b of the first rack 101 may be fixedly connected between the first portion 101a and the third portion 101c. The fourth portion 101d of the first rack 101 may be fixedly connected to the first portion 101a and the third portion 101c of the first rack 101, and is located on one side of the first portion 101a and the third portion 101c.

[0192] In this embodiment, the first portion 101a, the second portion 101b, and the third portion 101c of the first frame 101 can form an "I"-shaped structure or a "C"-shaped structure to make the structure of the first frame 101 more stable. Furthermore, the fourth portion 101d of the first frame 101 is located on one side of the first portion 101a and the third portion 101c of the first frame 101, which can further improve the overall structural stability of the first frame 101.

[0193] In addition, the fourth part 101d of the first frame 101 can also be fixedly connected to the second part 101b of the first frame 101 to further improve the structural stability of the first frame 101.

[0194] There can be two first actuating arms 2, which are located in the first space 1011. The second end 22 of one of the first actuating arms 2 is fixedly connected to the first part 101a of the first frame 101, and the second end 22 of the other first actuating arm 2 is fixedly connected to the third part 101c of the first frame 101.

[0195] In this embodiment, the stability of the image sensor 30 moving along the first direction D1 can be improved by setting two first actuation arms 2. In addition, the coordinated movement of the two first actuation arms 2 can increase the driving force for driving the image sensor 30 to move along the first direction D1, thereby improving the efficiency of driving the image sensor 30 to move along the first direction D1.

[0196] The first end 31 of the second actuator arm 3 can be fixedly connected to the second part 101b of the first frame 101.

[0197] In this embodiment, since the second part 101b of the first frame 101 is located in the middle region of the first frame 101 in the first direction D1, the first end 31 of the second actuating arm 3 can be connected to the middle region of the first frame 101 in the first direction D1, which helps to improve the stability of the second actuating arm 3 driving the first frame 101 as a whole to move along the second direction D2, and further helps to improve the stability of the image sensor 30 moving along the second direction D2.

[0198] The first end 31 of the second actuator arm 3 can be fixedly connected to the center of the second part 101b of the first frame 101 in the first direction D1, so as to further improve the stability of the second actuator arm 3 driving the first frame 101 to move along the second direction D2, thereby further improving the stability of the image sensor 30 moving along the second direction D2.

[0199] It should be noted that the first end 31 of the second actuating arm 3 can also be fixedly connected to other positions of the first frame 101. For example, the first end 31 of the second actuating arm 3 can also be fixedly connected to the first part 101a, the third part 101c, or the fourth part 101d of the first frame 101, etc., as long as the first end 31 of the second actuating arm 3 can drive the first frame 101 to move along the second direction D2 through deformation.

[0200] It should be noted that the shape of the first frame 101 shown in the embodiments of Figures 5A to 5C is only schematic. In some other embodiments, the first frame 101 may be other structures. For example, the first frame 101 may be flat, "L"-shaped, or irregular in shape, etc. There are no restrictions here. The design is based on the number of first actuating arms 2, their setting position, actual needs, etc.

[0201] For example, the motor 10 may also include a first transmission member 4. The first transmission member 4 may be located in the first space 1011, and two first actuating arms 2 are fixedly connected to both ends of the first transmission member 4. The first transmission member 4 is used to mount the image sensor 30.

[0202] In this embodiment, the image sensor 30 is mounted via the first transmission member 4, and two first actuating arms 2 are fixedly connected. This allows the first actuating arms 2 to move along the first direction D1 by driving the first transmission member 4 to move, thereby moving the image sensor 30 along the first direction D1. The first transmission member 4 helps improve the connection stability between the first actuating arms 2 and the image sensor 30, and avoids the structural limitations of a direct connection between the first actuating arms 2 and the image sensor 30. Furthermore, since the two ends of the first transmission member 4 are fixedly connected to the two first actuating arms 2, the coordination and consistency of the movement of the two first actuating arms 2 after deformation can be improved, thereby improving the stability of moving the image sensor 30 along the first direction D1.

[0203] In this embodiment, the first end 21 of the first actuating arm 2 can be embedded in the first transmission member 4 to improve the connection stability between the first actuating arm 2 and the first transmission member 4. In other embodiments, the first end 21 of the first actuating arm 2 can also be bonded to the first transmission member 4.

[0204] The first transmission member 4 may include a first part 4a, a second part 4b, and a third part 4c connected in sequence. The first part 4a and the third part 4c of the first transmission member 4 may be arranged opposite to each other along a first direction D1, and the first part 4a and the third part 4c of the first transmission member 4 are connected to the same side of the second part 4b of the first transmission member 4. The first part 4a of the first transmission member 4 is fixedly connected to the first end 21 of a first actuating arm 2, and the third part 4c of the first transmission member 4 is fixedly connected to the first end 21 of another first actuating arm 2.

[0205] In this embodiment, the first part 4a, the second part 4b, and the third part 4c of the first transmission member 4 can form a semi-enclosed arrangement of the image sensor 30, which is beneficial to improving the stability of the image sensor 30 mounted on the first transmission member 4. Furthermore, the arrangement of the first part 4a and the third part 4c of the first transmission member 4 is beneficial to improving the stability of the first actuating arm 2 driving the first transmission member 4 to move along the first direction D1.

[0206] For example, the motor 10 may further include an electrode 5 and a conductive wire 6, which are located in the first space 1011. The electrode 5 may be fixedly mounted on the first part 101a and the third part 101c of the first frame 101 and fixedly connected to the second end 22 of the first actuating arm 2. The conductive wire 6 may be electrically connected to the electrode 5 and wired along the first frame 101.

[0207] In this embodiment, the first actuator arm 2 can be connected to an external power source through the electrode 5 and the conductive wire 6 to receive the drive signal, so that the first actuator arm 2 can drive the image sensor 30 to move along the first direction D1.

[0208] For example, the motor 10 may also include a position detection component 7 for detecting the position of the image sensor 30.

[0209] In this embodiment, by setting the position detection component 7, the position of the image sensor 30 can be detected, so that during the image stabilization process, the position detection component 7 can provide real-time feedback on the position of the image sensor 30, which helps to improve the motion accuracy of the image sensor 30 and thus improve the image stabilization effect.

[0210] The position detection component 7 may include a magnet 71 and a magnetic sensor 72. The magnet 71 may be fixedly mounted on the first portion 4a and / or the third portion 4c of the first transmission member 4. The magnetic sensor 72 may be fixedly mounted on the first portion 101a and / or the third portion 101c of the first frame 101 and electrically connected to the conductive wire 6. The magnet 71 and the magnetic sensor 72 are arranged opposite to each other.

[0211] In this embodiment, by measuring the relative position between the magnet 71 and the magnetic sensor 72, the change in the magnetic field between the magnet 71 and the magnetic sensor 72 can be detected, thereby detecting the position information of the image sensor 30.

[0212] The magnet 71 can be embedded in the first transmission component 4 to improve the installation stability of the magnet 71 and save installation space.

[0213] In some examples, the magnet 71 and the magnetic sensor 72 can be positioned opposite each other along a direction perpendicular to the first direction D1. In this case, the position of the image sensor 30 relative to the first frame 101 can be determined based on the area of ​​the region where the magnet 71 and the magnetic sensor 72 face each other. The stronger the magnetic field between the magnet 71 and the magnetic sensor 72, the larger the area of ​​the region where the magnet 71 and the magnetic sensor 72 face each other.

[0214] In other examples, the magnet 71 and the magnetic sensor 72 can be positioned opposite each other along the first direction D1, and the position of the image sensor 30 relative to the first frame 101 can be determined based on the relative distance between the magnet 71 and the magnetic sensor 72. The stronger the magnetic field between the magnet 71 and the magnetic sensor 72, the smaller the distance between them.

[0215] In some embodiments, the second frame 102 may include a first portion 102a and a second portion 102b. The first portion 102a of the second frame 102 may be located on the side of the second portion 101b of the first frame 101 facing away from the first space 1011. The second portion 102b of the second frame 102 may be connected to one side of the first portion 102a of the second frame 102. The second portion 102b of the second frame 102 is located on the side of the fourth portion 101d of the first frame 101 facing away from the first space 1011. The second actuating arm 3 may be located between the first portion 102a of the second frame 102 and the second portion 101b of the first frame 101, and both ends of the second actuating arm 3 are respectively fixedly connected to the first portion 102a of the second frame 102 and the second portion 101b of the first frame 101.

[0216] In this embodiment, the second actuating arm 3 is disposed between the second part 101b of the first frame 101 and the first part 102a of the second frame 102, so that the first part 102a of the second frame 102, the second actuating arm 3 and the second part 101b of the first frame 101 are arranged sequentially along the second direction D2. Since the second actuating arm 3 is used to drive the first frame 101 to move along the second direction D2, the arrangement of the first part 102a of the second frame 102, the second actuating arm 3 and the second part 101b of the first frame 101 is beneficial to the second actuating arm 3 using the first part 102a of the second frame 102 as support to drive the first frame 101 to move along the second direction D2, and makes the space occupied by the first part 102a of the second frame 102, the second actuating arm 3 and the second part 101b of the first frame 101 small, which is beneficial to the overall miniaturization design of the motor 10.

[0217] For example, the second portion 102b of the second rack 102 can be slidably connected to the fourth portion 101d of the first rack 101.

[0218] In this embodiment, the second part 102b of the second frame 102 and the fourth part 101d of the first frame 101 can be slidably connected by a sliding structure, so that the second actuator arm 3 deforms after being energized, causing the first frame 101 to slide relative to the second frame 102 along the second direction D2. Since the second part 102b of the second frame 102 and the fourth part 101d of the first frame 101 are slidably connected by a sliding structure, the second frame 102 can provide structural support for the first frame 101, which is beneficial to the stability of the movement of the first frame 101 relative to the second frame 102.

[0219] The sliding structure can be a groove structure, a roller structure, or a ball structure, as long as it can achieve a sliding connection between the fourth part 101d of the first frame 101 and the second part 102b of the second frame 102, and the first frame 101 can slide relative to the second frame 102 along the second direction D2.

[0220] It should be noted that the second actuator arm 3 can also be equipped with electrodes 5 and conductive wires 6 to provide an external power source for the second actuator arm 3. For example, the electrodes 5 and conductive wires 6 connected to the second actuator arm 3 can be installed on the first part 102a of the second frame 102.

[0221] It should be noted that in some embodiments, the second actuating arm 3 may also be provided with a position detection component 7 to detect the position change of the image sensor 30 relative to the second frame 102. For example, the magnet 71 in the position detection component 7 provided for the second actuating arm 3 may be installed on the first frame 101, and the magnetic sensor 72 may be installed on the second frame 102, with the magnet 71 and the magnetic sensor 72 facing each other.

[0222] In some examples, magnet 71 and magnetic sensor 72 can be arranged opposite each other along a direction perpendicular to the second direction D2. In this case, the position of image sensor 30 relative to the second frame 102 can be determined based on the area of ​​the region where magnet 71 and magnetic sensor 72 are directly opposite each other. The stronger the magnetic field between magnet 71 and magnetic sensor 72, the larger the area of ​​the region where magnet 71 and magnetic sensor 72 are directly opposite each other.

[0223] In other examples, the magnet 71 and the magnetic sensor 72 can be positioned relative to each other along the second direction D2. In this case, the position of the image sensor 30 relative to the second frame 102 can be determined based on the relative distance between the magnet 71 and the magnetic sensor 72. The stronger the magnetic field between the magnet 71 and the magnetic sensor 72, the smaller the distance between them.

[0224] Please refer to Figures 5A to 5C for the following description of the focusing design of motor 10.

[0225] In some embodiments, the motor 10 may further include a third actuating arm 8, and the frame 1 may further include a third frame 103. The third actuating arm 8 may include a first end 81 and a second end 82. The first end 81 of the third actuating arm 8 is fixedly connected to the second frame 102, and the second end 82 of the third actuating arm 8 is fixedly connected to the third frame 103. The third actuating arm 8 is used to deform upon being energized, thereby moving the second frame 102 relative to the third frame 103 along a third direction D3.

[0226] In this embodiment, the third actuator arm 8 can drive the second frame 102, the second actuator arm 3, the first frame 101, the first actuator arm 2, and the image sensor 30 to move together relative to the third frame 103 along a third direction D3, thereby achieving focusing of the camera module 100. Since the third actuator arm 8 can drive the second frame 102, the second actuator arm 3, the first frame 101, the first actuator arm 2, and the image sensor 30 to move together, the movement of the third actuator arm 8 does not interfere with the movement of the first actuator arm 2 and the second actuator arm 3. That is, the focusing and image stabilization of the camera module 100 do not interfere with each other. For example, image stabilization can be performed during focusing, or focusing can be performed during image stabilization, and the movement between the two will not affect each other's effect.

[0227] For example, the third frame 103, the third actuator arm 8 and the second frame 102 are arranged sequentially in the third direction D3.

[0228] In this embodiment, since the movement direction of the third actuating arm 8 driving the second frame 102 is the third direction D3, the arrangement direction of the third frame 103, the third actuating arm 8 and the second frame 102 is the same as the movement direction of the second frame 102 relative to the third frame 103 driven by the third actuating arm 8. This allows the third actuating arm 8 to deform along the third direction D3, thereby driving the second frame 102 to move relative to the third frame 103 along the third direction D3, which is beneficial to improving the efficiency of the third actuating arm 8 driving the second frame 102.

[0229] The first end 81 of the third actuating arm 8 can be connected to the middle region of the second frame 102 to improve the stability of the movement of the second frame 102 driven by the third actuating arm 8. It should be noted that the first end 81 of the third actuating arm 8 can be connected to the middle region of the second frame 102 along the first direction D1, the middle region of the second frame 102 along the second direction D2, or the center region of the second frame 102.

[0230] The third actuating arm 8 can include a piezoelectric material, allowing it to deform at its end using the piezoelectric effect after being energized. This results in a larger displacement and thrust, and enables higher frequency deformation, which is beneficial for the camera module 100 to achieve rapid focusing. Furthermore, since the third actuating arm 8 can be designed using piezoelectric materials, there is no need for a drive motor composed of magnets and wound coils. This reduces the overall mass and size of the motor 10, enabling focusing within a smaller space and reducing electromagnetic interference.

[0231] The third actuating arm 8 can be plate-shaped, with its plate surface perpendicular to the third direction D3. This allows the end of the third actuating arm 8 connecting to the second frame 102 to warp along the third direction D3, thereby enabling the second frame 102 to move along the third direction D3 and improving the efficiency of this movement. Furthermore, the plate-shaped structure of the third actuating arm 8 reduces the space it occupies in the third direction D3, improving the space utilization of the motor 10 and reducing its size. Additionally, the plate-shaped structure of the third actuating arm 8 increases the contact area between the third actuating arm 8 and the second frame 102, thus improving the motion stability of the image sensor 30.

[0232] The third actuator arm 8 can have a bent or curved structure, which is beneficial to increase the total length of the third actuator arm 8 in the same space. This allows the first end 81 of the third actuator arm 8 to undergo greater deformation after being powered on, thereby driving the image sensor 30 to achieve greater displacement and improving the image stabilization capability of the camera module 100.

[0233] The number of third actuators 8 can be one or more, and there is no limit to the number of them.

[0234] The third frame 103 can be part of the inner wall of the housing of the camera module 100, or the motor 10 can be without the third frame 103, with the second end 82 of the third actuating arm 8 fixedly connected to the inner wall of the housing of the camera module 100, so that the motor 10 can use the inner wall of the housing of the camera module 100 as a support structure, which is beneficial to the miniaturization design of the camera module 100.

[0235] It should be noted that the third actuator arm 8 can also be equipped with electrodes 5 and conductive wires 6 to provide an external power source for the third actuator arm 8. For example, the electrodes 5 and conductive wires 6 connected to the third actuator arm 8 can be installed on the third frame 103.

[0236] It should be noted that the third actuator arm 8 may also be provided with a position detection component 7 to detect the position change of the image sensor 30 relative to the third frame 103, thereby obtaining the focal length change of the lens 20. For example, the magnet 71 in the position detection component 7 provided for the third actuator arm 8 can be installed on the second frame 102, and the magnetic sensor 72 can be installed on the third frame 103, with the magnet 71 and the magnetic sensor 72 facing each other.

[0237] In some embodiments, the first frame 101 and the second frame 102 can be movably connected to the inner wall of the housing of the camera module 100, so that the housing of the camera module 100 can provide structural support for the first frame 101 and the second frame 102, thereby improving the stability of the translation of the image sensor 30 driven by the motor 10.

[0238] For example, the first frame 101 can be connected to the inner wall of the housing of the camera module 100 via a rolling structure, so that during the image stabilization compensation process, the motor 10 can drive the first frame 101 to move relative to the housing of the camera module 100 along the second direction D2 via the second actuator arm 3. Since the first frame 101 can be connected to the inner wall of the housing of the camera module 100 via a rolling structure, the housing of the camera module 100 can provide structural support for the first frame 101 to move along the second direction D2, and can also reduce the friction between the first frame 101 and the housing of the camera module 100.

[0239] Furthermore, when the motor drives the second frame 102 and the first frame 101 to move together along the third direction D3 via the third actuating arm 8, the first frame 101 can move relative to the housing of the camera module 100 along the third direction D3 via the rolling structure, so that the housing of the camera module 100 can provide structural support for the first frame 101 when it moves along the third direction D3, and can also reduce the friction between the first frame 101 and the housing of the camera module 100.

[0240] For example, the second frame 102 can be connected to the inner wall of the housing of the camera module 100 via a sliding structure, so that the second frame 102 can move relative to the inner wall of the housing of the camera module 100 along a third direction D3 via the sliding structure, so that the housing of the camera module 100 can provide structural support for the second frame 102 when it moves along the third direction D3, and can also reduce the friction between the second frame 102 and the housing of the camera module 100.

[0241] It should be noted that the second frame 102 can also be connected to the inner wall of the housing of the camera module 100 through a rolling structure, so as to further reduce the friction between the second frame 102 and the housing of the camera module 100 when the second frame 102 moves relative to the housing of the camera module 100.

[0242] It is understood that Figures 5A to 5C only schematically show some of the components included in the motor 10. The actual shape, size, location and construction of these components are not limited by Figures 5A to 5C, and the motor 10 may include more or fewer components than those in Figures 5A to 5C.

[0243] Please refer to Figures 5A to 5C for the following description of the structure of motor 10 when it only has a vibration stabilization design.

[0244] In some embodiments, the motor 10 may not include the third actuation arm 8 and the third frame 103; in other words, the motor 10 has image stabilization but no focusing function. In this embodiment, the motor 10 can drive the image sensor 30 to move in the first direction D1 and the second direction D2 through the first actuation arm 2 and the second actuation arm 3 to achieve image stabilization compensation of the camera module 100.

[0245] For example, the second frame 102 may be part of the housing of the camera module 100.

[0246] In this embodiment, since the motor 10 only needs the first frame 101 to move together with the image sensor 30 during the image stabilization compensation process, and the second frame 102 does not need to move, a part of the housing of the camera module 100 can be reused as the second frame 102 to further simplify the structure of the motor 10 and reduce the size of the motor 10, thereby facilitating the miniaturization design of the camera module.

[0247] Specifically, the bottom wall of the housing of the camera module 100 can be the second part 102b of the second frame 102, and one side wall of the housing of the camera module 100 can be the first part 102a of the second frame 102. In particular, the bottom wall of the housing of the camera module 100 near the image sensor and the side wall bent and connected to the bottom wall are reused as the second part 102b and the first part 102a of the second frame 102, respectively, to simplify the structure of the motor 10.

[0248] Please refer to Figures 6A to 6C. Figure 6A is a structural schematic diagram of the motor 10 in the camera module 100 shown in Figure 4A in some other embodiments; Figure 6B is a partially exploded structural schematic diagram of the motor 10 shown in Figure 6A in some embodiments; Figure 6C is a structural schematic diagram of the motor 10 shown in Figure 6A from another perspective. It should be noted that the motor 10 shown in Figures 6A to 6C may include some structural features of the motor 10 shown in Figures 5A to 5C. Technical features identical to those of the motor 10 shown in Figures 6A to 6C will not be repeated. It should also be noted that, for ease of description, the first actuating arm 2 and the second actuating arm 3 in Figure 6C are marked with a grid. The grid is only used to highlight the first actuating arm 2 and the second actuating arm 3 and is not a cross-sectional structure.

[0249] In some embodiments, the motor 10 may further include a first rolling element 9 and a second rolling element 11. The first rolling element 9 may be connected between the first end 21 of the first actuating arm 2 and the first transmission member 4, and the second end 32 of the second actuating arm 3 may be fixedly connected to the frame 1. The second rolling element 11 may be connected between the first end 31 of the second actuating arm 3 and the first transmission member 4, and the second end 32 of the second actuating arm 3 may be fixedly connected to the frame 1. The second actuating arm 3 is used to drive the image sensor 30 to move relative to the frame 1 along a second direction D2.

[0250] In this embodiment, when the first actuating arm 2 is energized and deforms, it can drive the first rolling element 9, the first transmission element 4, and the image sensor 30 to move together along the first direction D1. Since the first end 31 of the second actuating arm 3 is connected to the first transmission element 4 through the second rolling element 11, the first transmission element 4 can move relative to the second actuating arm 3 through the rolling of the second rolling element 11. Similarly, when the second actuating arm 3 is energized and deforms, it can drive the second rolling element 11, the first transmission element 4, and the image sensor 30 to move together along the second direction D2. Since the first end 21 of the first actuating arm 2 is connected to the first transmission element 4 through the first rolling element 9, the first transmission element 4 can move relative to the first actuating arm 2 through the rolling of the first rolling element 9. Therefore, through the design of the first rolling element 9 and the second rolling element 11, the motion interference between the first actuating arm 2 and the second actuating arm 3 can be reduced or even eliminated. Furthermore, the first actuating arm 2 and the second actuating arm 3 can share the same frame 1, eliminating the need for two nested frames, which helps reduce the size of the motor 10 and thus facilitates the miniaturization design of the camera module 100.

[0251] For example, the frame 1 may include a first part 1a, a second part 1b, and a third part 1c connected sequentially. The first part 1a and the third part 1c of the frame 1 may be arranged opposite each other along a first direction D1, and the second part 1b of the frame 1 is connected between the first part 1a and the third part 1c of the frame 1. The first part 1a, the second part 1b, and the third part 1c of the frame 1 may enclose a second space 104, which is used to accommodate the first actuating arm 2, the second actuating arm 3, the first transmission member 4, the first rolling member 9, and the second rolling member 11.

[0252] In this embodiment, the first actuating arm 2, the second actuating arm 3, the first transmission member 4, the first rolling member 9, and the second rolling member 11 are all disposed in the second space 104, which is beneficial for the frame 1 to protect the first actuating arm 2, the second actuating arm 3, the first transmission member 4, the first rolling member 9, the second rolling member 11, and the image sensor 30.

[0253] It should be noted that the motor 10 shown in Figures 6A to 6C may include only one frame structure, and the frame 1 in the motor 10 shown in Figures 6A to 6C may have the same or similar structure as the first frame 101 in Figures 5A to 5C.

[0254] The first part 1a of the frame 1 can extend along the second direction D2, and the second part 1b of the frame 1 can extend along the first direction D1. The second end 22 of the first actuating arm 2 can be fixedly connected to the first part 1a of the frame 1, and the second end 32 of the second actuating arm 3 can be fixedly connected to the second part 1b of the frame 1.

[0255] In this embodiment, the first portion 1a of the frame 1 extends along the second direction D2, which helps to reduce the structural interference of the first portion 1a of the frame 1 on the movement of the image sensor 30 by the second actuating arm 3 along the second direction D2. This helps to reduce the distance between the image sensor 30 and the first portion 1a of the frame 1 in the first direction D1, and thus facilitates the small-size design of the motor 10. The second portion 1b of the frame 1 extends along the first direction D1, which helps to reduce the structural interference of the second portion 1b of the frame 1 on the movement of the image sensor 30 by the first actuating arm 2 along the first direction D1. This helps to reduce the distance between the image sensor 30 and the second portion 1b of the frame 1 in the second direction D2, and thus facilitates the small-size design of the motor 10.

[0256] The number of first actuating arms 2 can be two, with the second end 22 of one first actuating arm 2 fixedly connected to the first part 1a of the frame 1, and the second end 22 of the other first actuating arm 2 fixedly connected to the third part 1c of the frame 1.

[0257] In this embodiment, the stability of the image sensor 30 moving along the first direction D1 can be improved by setting two first actuation arms 2. In addition, the coordinated movement of the two first actuation arms 2 can increase the driving force for driving the image sensor 30 to move along the first direction D1, thereby improving the efficiency of driving the image sensor 30 to move along the first direction D1.

[0258] In this configuration, one of the two first actuating arms 2 can be connected to the first part 4a of the first transmission member 4 via a first rolling element 9, and the other first actuating arm 2 can be connected to the third part 4c of the first transmission member 4 via another rolling element. The first end 31 of the second actuating arm 3 can be connected to the second part 4b of the first transmission member 4 via a second rolling element 11.

[0259] In this embodiment, since the first transmission member 4 is an integral structure, by connecting the two first actuating arms 2 and the second actuating arm 3 to different parts of the first transmission member 4 respectively, the layout of the first actuating arm 2 and the second actuating arm 3 is optimized, which can reduce motion interference between the first actuating arm 2 and the second actuating arm 3. In addition, the first part 4a, the second part 4b and the third part 4c of the first transmission member 4 can form a semi-enclosed arrangement of the image sensor 30, which is beneficial to improving the stability of the image sensor 30 mounted on the first transmission member 4. Moreover, the arrangement of the first part 4a and the third part 4c of the first transmission member 4 is beneficial to improving the stability of the first actuating arm 2 driving the first transmission member 4 to move along the first direction D1.

[0260] The first rolling element 9 may include multiple balls, and the second rolling element 11 may include multiple balls. The number of balls in the first rolling element 9 and the second rolling element 11 is not limited here.

[0261] Specifically, a first preload can be present between the first actuating arm 2 and the first transmission member 4. The direction of the first preload is parallel to the first direction D1, which can prevent the first actuating arm 2 and the first transmission member 4 from detaching during the movement of the image sensor 30, thereby improving the connection stability between the first actuating arm 2 and the first transmission member 4. For example, the first preload can be achieved by magnetic attraction or elastic force.

[0262] Specifically, a second preload can be present between the second actuating arm 3 and the first transmission member 4. The direction of the second preload is parallel to the second direction D2, which can prevent the second actuating arm 3 from detaching from the first transmission member 4 during the movement of the image sensor 30, thereby improving the connection stability between the second actuating arm 3 and the first transmission member 4. For example, the second preload can be achieved through magnetic attraction or elastic force.

[0263] Please refer to Figures 6A, 6C, and 6D. Figure 6D is a structural schematic diagram of the motor 10 shown in Figure 6A from another perspective. It should be noted that, for ease of description, the third actuating arm 8 in Figure 6D is marked with a grid. The grid is only used to highlight the third actuating arm 8 and is not a cross-sectional structure.

[0264] In some embodiments, the motor 10 may further include a third rolling element 12. The third actuating arm 8 and the third rolling element 12 may be located in the second space 104. The first end 81 of the third actuating arm 8 may be connected to the first transmission member 4 via the third rolling element 12, and the second end 82 of the third actuating arm 8 may be fixedly connected to the frame 1. The third actuating arm 8 is used to deform after being energized, thereby driving the first transmission member 4 and the image sensor 30 to move relative to the frame 1 along a third direction D3.

[0265] In this embodiment, the third actuating arm 8 drives the first transmission member 4 and the image sensor 30 to move together relative to the first frame 101 along a third direction D3, thereby achieving focusing of the camera module 100. The first end 21 of the first actuating arm 2 is connected to the first transmission member 4 via the first rolling member 9, and the first end 31 of the second actuating arm 3 is connected to the first transmission member 4 via the second rolling member 11. This allows the first transmission member 4 to move relative to the first actuating arm 2 via the rolling of the first rolling member 9, and the first transmission member 4 to move relative to the second actuating arm 3 via the rolling of the second rolling member 11. Therefore, the design of the first rolling member 9 and the second rolling member 11 can reduce or even eliminate motion interference between the third actuating arm 8 and the first actuating arm 2 and the second actuating arm 3. Thus, focusing and image stabilization of the camera module 100 do not interfere with each other. For example, image stabilization can be performed during focusing, or focusing can be performed during image stabilization, and the movement between the two will not affect each other's effect. In addition, the first actuator arm 2, the second actuator arm 3 and the third actuator arm 8 can share the same frame 1, eliminating the need for multiple frames with nested structures, which helps to reduce the size of the motor 10, thereby facilitating the miniaturization design of the camera module 100.

[0266] For example, the frame 1 may further include a fourth part 1d, which can be fixedly connected to the first part 1a and the third part 1c of the frame 1, and is located on one side of the first part 1a and the third part 1c of the frame 1. The third actuating arm 8 is located between the fourth part 1d of the frame 1 and the third rolling element 12, and both ends of the third actuating arm 8 are respectively connected to the fourth part 1d of the frame 1 and the third rolling element 12.

[0267] In this embodiment, the third actuating arm 8 is located between the fourth part 1d of the frame 1 and the third rolling member 12, so that the fourth part 1d of the frame 1, the third actuating arm 8, the third rolling member 12 and the first transmission member 4 can be arranged sequentially in the third direction D3. This is beneficial for the third actuating arm 8 to bend and deform along the third direction D3 to drive the first transmission member 4 to move the image sensor 30 relative to the frame 1 along the third direction D3, and also helps to improve the space utilization of the motor 10.

[0268] The number of third actuating arms 8 and third rolling elements 12 can be two. One third actuating arm 8 is connected to the first part 4a of the first transmission member 4 through a third rolling element 12, and the other third actuating arm 8 is connected to the third part 4c of the first transmission member 4 through another third rolling element 12.

[0269] In this embodiment, by setting the two third actuating arms 8 and the third rolling element 12 to correspond to the first part 4a and the third part 4c of the first transmission element 4 respectively, it is beneficial to balance the movement of the third actuating arm 8 driving the first transmission element 4 along the third direction D3, thereby improving the balance of the image sensor 30 moving along the third direction D3.

[0270] The third rolling element 12 may include a plurality of balls, and the number of balls in the third rolling element 12 is not limited here.

[0271] Specifically, a third preload can be present between the third actuating arm 8 and the first transmission member 4. The direction of the third preload is parallel to the third direction D3, which can prevent the image sensor 30 from detaching from the third actuating arm 8 and the first transmission member 4 during movement, thereby improving the connection stability between the third actuating arm 8 and the first transmission member 4. For example, the third preload can be achieved through magnetic attraction or elastic force.

[0272] The first transmission member 4 may further include a fourth part 4d and a fifth part 4e. The fourth part 4d of the first transmission member 4 may have a plate structure perpendicular to the third direction D3, and the fifth part 4e of the first transmission member 4 may also have a plate structure perpendicular to the third direction D3. The fourth part 4d of the first transmission member 4 is fixedly connected to the first part 4a of the first transmission member 4, and is located on the side of the first part 4a of the first transmission member 4 closer to the fourth part 1d of the frame 1. The fifth part 4e of the first transmission member 4 is fixedly connected to the third part 4c of the first transmission member 4, and is located on the side of the third part 4c of the first transmission member 4 closer to the fourth part 1d of the frame 1.

[0273] In this embodiment, by setting the fourth part 4d and the fifth part 4e of the first transmission member 4, it is beneficial to increase the contact surface between the third rolling member 12 and the first transmission member 4, thereby improving the stability of the third actuating arm 8 driving the first transmission member 4 to move along the third direction D3, and thus improving the stability of the third actuating arm 8 driving the image sensor 30 to move along the third direction D3.

[0274] In some other embodiments, one of the two third rolling elements 12 can be directly connected to the first part 4a of the first transmission element 4, and the other third rolling element 12 can be directly connected to the third part 4c of the first transmission element 4.

[0275] In some embodiments, the position detection component 7 may be a single unit. The position of the image sensor 30 relative to the frame 1 can be detected by the relative position of the magnet 71 and the magnetic sensor 72 within the position detection component 7. Specifically, the magnetic sensor 72 may be mounted on the frame 1, and the magnet 71 may be mounted on the first transmission member 4, with the magnetic sensor 72 and the magnet 71 facing each other. During movement, the image sensor 30 changes the size, area, and spacing of the parts of the magnet 71 and the magnetic sensor 72 facing each other, thereby changing the magnetic field between them. The position of the image sensor 30 is then determined based on this change in the magnetic field.

[0276] The magnetic sensor 72 can be installed in any one of the first part 1a, the second part 1b, the third part 1c, and the fourth part 1d of the frame 1, as long as the magnet 71 can be positioned directly opposite the magnetic sensor 72.

[0277] The number of position detection components 7 can be set to multiple to improve the position detection accuracy of the image sensor 30.

[0278] Please refer to Figures 7A to 7C. Figure 7A is a structural schematic diagram of the motor 10 in the camera module 100 shown in Figure 4A in some embodiments; Figure 7B is a partially exploded structural schematic diagram of the motor 10 shown in Figure 7A in some embodiments; Figure 7C is a structural schematic diagram of the motor 10 shown in Figure 7A from another perspective. It should be noted that the motor 10 shown in Figures 7A to 7C may include some structural features of the motor 10 shown in Figures 5A to 5C. Technical features identical to those of the motor 10 shown in Figures 7A to 7C will not be repeated. It should also be noted that, for ease of description, the first actuating arm 2 and the second actuating arm 3 in Figure 7C are marked with a grid. The grid is only used to highlight the first actuating arm 2 and the second actuating arm 3 and is not a cross-sectional structure.

[0279] In some embodiments, the second end 22 of the first actuating arm 2 and the second end 32 of the second actuating arm 3 can both be fixedly connected to the first frame 101. The motor 10 may also include a second transmission member 13 and a third transmission member 14 spaced apart. The second transmission member 13 is fixedly connected to the first end 21 of the first actuating arm 2, and has a first sliding structure 131 extending along a second direction D2. The first sliding structure 131 is used to connect to the image sensor 30. The third transmission member 14 is fixedly connected to the first end 31 of the second actuating arm 3, and has a second sliding structure 141 extending along a first direction D1. The second sliding structure 141 is used to connect to the image sensor 30.

[0280] In this embodiment, by providing a second sliding structure 141 on the third transmission member 14, the image sensor 30 can slide relative to the third transmission member 14 via the second sliding structure 141 during the movement of the first actuating arm 2, which drives the second transmission member 13 and the image sensor 30 along the first direction D1. This prevents the image sensor 30 from driving the third transmission member 14 and the second actuating arm 3 during the movement along the first direction D1. Similarly, by providing a first sliding structure 131 on the second transmission member 13, the image sensor 30 can slide relative to the second transmission member 13 via the first sliding structure 131 during the movement of the second actuating arm 3, which drives the third transmission member 14 and the image sensor 30 along the second direction D2. This prevents the image sensor 30 from driving the second transmission member 13 and the first actuating arm 2 during the movement along the second direction D2. Therefore, by setting the first sliding structure 131 and the second sliding structure 141, the movement interference of the image sensor 30 in the two directions D1 and D2 can be avoided, effectively reducing or even eliminating the hysteresis of the image sensor 30 in the first direction D1 and the second direction D2, thereby improving the smoothness of the image sensor 30's image stabilization compensation. In addition, the first actuator arm 2 and the second actuator arm 3 can be interchangeable with the first frame 101, eliminating the need for two nested frames 1, which helps to reduce the size of the motor 10, thus facilitating the miniaturization design of the camera module 100.

[0281] For example, the first actuating arm 2 can be connected between the first part 101a of the first frame 101 and the second transmission member 13, and the second actuating arm 3 can be connected between the second part 101b of the first frame 101 and the third transmission member 14.

[0282] In this embodiment, the arrangement of the first actuating arm 2 allows the first portion 101a of the first frame 101 and the second transmission member 13 to be arranged in the first direction D1, which facilitates the first actuating arm 2 driving the second transmission member 13 to move the image sensor 30 along the first direction D1. Similarly, the arrangement of the second actuating arm 3 allows the second portion 101b of the first frame 101 and the third transmission member 14 to be arranged in the second direction D2, which facilitates the second actuating arm 3 driving the third transmission member 14 to move the image sensor 30 along the second direction D2.

[0283] There can be two first actuating arms 2, and correspondingly, there can be two second transmission members 13. One first actuating arm 2 can be connected between the first part 101a of the first frame 101 and one second transmission member 13, and the other first actuating arm 2 can be connected between the third part 101c of the first frame 101 and another second transmission member 13.

[0284] The first sliding structure 131 can be a groove structure, a roller structure, or a ball structure, as long as it can achieve a sliding connection between the second transmission member 13 and the image sensor 30, and the image sensor 30 can slide relative to the second transmission member 13 along the second direction D2.

[0285] A first limiting structure can be provided between the first sliding structure 131 and the image sensor 30. The first limiting structure is used to provide a limit parallel to the first direction D1, which can prevent the image sensor 30 from falling off the first sliding structure 131 when the first actuating arm 2 drives the image sensor 30 to move along the first direction D1.

[0286] The second sliding structure 141 can be a groove structure, a roller structure, or a ball structure, as long as it can achieve a sliding connection between the third transmission member 14 and the image sensor 30, and the image sensor 30 can slide relative to the third transmission member 14 along the first direction D1.

[0287] A second limiting structure can be provided between the second sliding structure 141 and the image sensor 30. The second limiting structure is used to provide a limit parallel to the second direction D2, which can prevent the image sensor 30 from falling off the second sliding structure 141 when the second actuating arm 3 drives the image sensor 30 to move along the second direction D2.

[0288] It should be noted that in the embodiments of Figures 7A and 7B, the first sliding structure 131 and the second sliding structure 141 are both illustrated using a sliding groove. It can be understood that the embodiments of Figures 7A and 7B do not limit the specific structure of the first sliding structure 131 and the second sliding structure 141.

[0289] Please refer to Figures 7A, 7C, and 7D. Figure 7D is a structural schematic diagram of the motor 10 shown in Figure 7A from another perspective. It should be noted that, for ease of description, the third actuating arm 8 in Figure 7D is marked with a grid. The grid is only used to highlight the third actuating arm 8 and is not a cross-sectional structure.

[0290] In some embodiments, the motor 10 may further include a third actuating arm 8, and the frame 1 may further include a third frame 103. The first end 81 of the third actuating arm 8 is fixedly connected to the first frame 101, and the second end 82 of the third actuating arm 8 is fixedly connected to the third frame 103. The third actuating arm 8 is used to deform after being energized, thereby driving the first frame 101 to move relative to the third frame 103 along a third direction D3.

[0291] In this embodiment, the third actuator arm 8 can drive the second actuator arm 3, the first frame 101, the first actuator arm 2, and the image sensor 30 to move together relative to the third frame 103 along a third direction D3, thereby achieving focusing of the camera module 100. Since the third actuator arm 8 can drive the second actuator arm 3, the first frame 101, the first actuator arm 2, and the image sensor 30 to move together, the movement of the third actuator arm 8 does not interfere with the movement of the first actuator arm 2 and the second actuator arm 3. That is, focusing and image stabilization of the camera module 100 do not interfere with each other. For example, image stabilization can be performed during focusing, or focusing can be performed during image stabilization, and the movement between the two will not affect each other's effect.

[0292] For example, the third actuator arm 8 can be connected between the third frame 103 and the fourth part 101d of the first frame 101, with the third frame 103, the third actuator arm 8 and the fourth part 101d of the first frame 101 arranged sequentially in the third direction D3.

[0293] In this embodiment, since the third actuating arm 8 drives the first frame 101 to move in the third direction D3, the arrangement direction of the third frame 103, the third actuating arm 8, and the fourth part 101d of the first frame 101 is the same as the direction of movement of the first frame 101 relative to the third frame 103 driven by the third actuating arm 8. This allows the third actuating arm 8 to deform along the third direction D3, thereby enabling the first frame 101 to move relative to the third frame 103 along the third direction D3, which is beneficial to improving the efficiency of the third actuating arm 8 in driving the first frame 101.

[0294] Please refer to Figures 8A to 8C. Figure 8A is a structural schematic diagram of the motor 10 in the camera module 100 shown in Figure 4A in some embodiments; Figure 8B is a partially exploded structural schematic diagram of the motor 10 shown in Figure 8A in some embodiments; Figure 8C is a structural schematic diagram of the motor 10 shown in Figure 8A from another perspective. It should be noted that the motor 10 shown in Figures 8A to 8C may include some structural features of the motor 10 shown in Figures 5A to 5C. Technical features identical to those of the motor 10 shown in Figures 8A to 8C will not be repeated. It should also be noted that, for ease of description, the first actuating arm 2 and the second actuating arm 3 in Figure 8C are marked with a grid. The grid is only used to highlight the first actuating arm 2 and the second actuating arm 3 and is not a cross-sectional structure.

[0295] In some embodiments, the second frame 102 may have a third sliding structure 1021, which may extend along a second direction D2 and is connected to the first frame 101.

[0296] In this embodiment, by setting a third sliding structure 1021, the second actuating arm 3 deforms when energized, driving the first frame 101 to move relative to the second frame 102 along the third sliding structure 1021. This causes the image sensor 30 and the first actuating arm 2 to move together relative to the second frame 102 along the second direction D2. Furthermore, when the first actuating arm 2 deforms when energized, it drives the image sensor 30 to move relative to the first frame 101 along the first direction D1. Since the first frame 101 and the second frame 102 are relatively stationary, the design of the third sliding structure 1021 can reduce or even eliminate motion interference between the first actuating arm 2 and the second actuating arm 3.

[0297] For example, the second frame 102 can be connected to the first portion 101a and the third portion 101c of the first frame 101, and is located on one side of the first portion 101a and the third portion 101c of the first frame 101. In other words, compared to the first frame 101 in the motor 10 shown in Figures 5A to 5C, the first frame 101 in this embodiment may not include the fourth portion, and the second frame 102 can be directly slidably connected to the first portion 101a and the third portion 101c of the first frame 101.

[0298] In this embodiment, by setting the second frame 102 to be slidably connected to both the first part 101a and the third part 101c of the first frame 101, it is beneficial to reduce the size of the frame 1, thereby facilitating the miniaturization design of the motor 10.

[0299] The third sliding structure 1021 can be a groove structure, a roller structure, or a ball structure, as long as it can achieve a sliding connection between the first frame 101 and the second frame 102, and the first frame 101 can slide relative to the second frame 102 along the second direction D2.

[0300] The first end 21 of the first actuating arm 2 can be directly connected to the image sensor 30, or it can be connected to the image sensor 30 through the first transmission component 4.

[0301] The first end 31 of the second actuating arm 3 can be directly connected to the image sensor 30, or it can be connected to the image sensor 30 through the first transmission component 4.

[0302] Please refer to Figures 8A, 8C, and 8D. Figure 8D is a structural schematic diagram of the motor 10 shown in Figure 8A from another perspective. It should be noted that, for ease of description, the second actuating arm 3 and the third actuating arm 8 in Figure 8D are marked with a grid. The grid is only used to highlight the second actuating arm 3 and the third actuating arm 8, and is not a cross-sectional structure.

[0303] In some embodiments, the motor 10 may further include a third actuating arm 8, and the frame 1 may further include a third frame 103. The first end 81 of the third actuating arm 8 is fixedly connected to the second frame 102, and the second end 82 of the third actuating arm 8 is fixedly connected to the third frame 103. The third actuating arm 8 is used to deform after being energized, thereby driving the second frame 102 to move relative to the third frame 103 along a third direction D3.

[0304] In this embodiment, by setting a third frame 103 and a third actuator arm 8, the third actuator arm 8 can deform after being powered on, thereby moving the second frame 102, the second actuator arm 3, the first frame 101, the first actuator arm 2, and the image sensor 30 together along a third direction D3, thereby achieving focusing of the camera module 100. Since the third actuator arm 8 can move the second frame 102, the second actuator arm 3, the first frame 101, the first actuator arm 2, and the image sensor 30 together, the movement of the third actuator arm 8 does not interfere with the movement of the first actuator arm 2 and the second actuator arm 3. That is, the focusing and image stabilization of the camera module 100 do not interfere with each other. For example, image stabilization can be performed during focusing, or focusing can be performed during image stabilization, and the movement between the two will not affect each other's effect.

[0305] For example, the third frame 103, the third actuator arm 8 and the second frame 102 are arranged sequentially in the third direction D3.

[0306] In this embodiment, since the movement direction of the third actuating arm 8 driving the second frame 102 is the third direction D3, the arrangement direction of the third frame 103, the third actuating arm 8 and the second frame 102 is the same as the movement direction of the second frame 102 relative to the third frame 103 driven by the third actuating arm 8. This allows the third actuating arm 8 to deform along the third direction D3, thereby driving the second frame 102 to move relative to the third frame 103 along the third direction D3, which is beneficial to improving the efficiency of the third actuating arm 8 driving the second frame 102.

[0307] Please refer to Figures 2B and 9 in conjunction with each other. Figure 9 is a three-dimensional structural schematic diagram of the camera module 100 shown in Figure 2B in some embodiments. It should be noted that the camera module 100 shown in Figure 9 may include most of the technical features of the camera module 100 shown in Figure 4A. The technical features that are the same in the camera module 100 shown in Figure 9 and the camera module 100 shown in Figure 4A will not be repeated.

[0308] In some embodiments, the motor 10 may be arranged around a portion of the lens assembly 202 to reduce the space occupied by the motor 10 in the camera module 100.

[0309] In this embodiment, the motor 10 can utilize the peripheral space of the lens group 202, which can save space. Furthermore, the frame 1 structure in the motor 10 can reuse the lens barrel structure of the lens group 202, further reducing the space occupied by the motor 10 and facilitating the miniaturization design of the camera module 100.

[0310] It should be noted that the above embodiments are only illustrative. Other components such as the frame 1, actuator arm, and transmission components in the motor 10 can also adopt other matching structures to enable the image sensor 30 to achieve image stabilization and zoom under the drive of the motor 10.

[0311] It should be noted that the motor 10 provided in this application embodiment can also be applied to other application scenarios that require multi-directional translation, and is not limited here.

[0312] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other, and any combination of features in different embodiments is also within the protection scope of this application. That is to say, the multiple embodiments described above can also be arbitrarily combined according to actual needs.

[0313] It should be noted that all the above figures are exemplary illustrations of this application and do not represent the actual size of the product. Furthermore, the dimensional proportions between the components in the figures are not intended to limit the actual product of this application.

[0314] The above are merely some embodiments and implementation methods of this application. The scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
