Description

Technical Field

[0001] This application relates to the field of optical technology, specifically to a camera image stabilization drive motor, camera module, and electronic device. Background Technology

[0002] In the field of optics, motors are widely used in smartphone cameras, typically employing image stabilization drive structures to achieve image stabilization and improve image stability and clarity. When power is off, the springs inside the motor deform to move the moving object and lens, thereby returning them to their original positions. However, the arrangement of these springs is structurally complex and results in a relatively large camera stabilization drive motor, which is detrimental to the miniaturization of the camera module. Utility Model Content

[0003] In view of the above, it is necessary to propose a camera image stabilization drive motor, a camera module, and electronic equipment to reduce the size of the camera image stabilization drive motor, thereby facilitating the miniaturization of the camera module.

[0004] A first aspect of this application provides a camera image stabilization drive motor, comprising: a base; a movable body disposed on the base and movable along a preset direction; a rolling element disposed between the base and the movable body, a portion of the rolling element being rotatably accommodated within the base, and another portion of the rolling element being rotatably accommodated within the movable body; and an image stabilization drive structure, comprising an image stabilization coil, an image stabilization magnet, and a return magnetic guide, wherein the image stabilization coil and the image stabilization magnet are disposed opposite to each other, one of the image stabilization coil and the image stabilization magnet is disposed on the base, the other of the image stabilization coil and the image stabilization magnet is disposed on the movable body, and the other of the return magnetic guide and the image stabilization magnet is disposed on the base, wherein the return magnetic guide is used to have an attractive force with the image stabilization magnet in the preset direction when power is off, so that the movable body moves to an initial position along the preset direction.

[0005] In the solution provided in this application embodiment, the image stabilization coil and image stabilization magnet in the image stabilization drive structure are respectively disposed on the base and the moving body and arranged opposite to each other. This design allows the image stabilization function to be achieved through the interaction between the image stabilization coil and the image stabilization magnet during normal operation, ensuring the stability and clarity of the image and meeting the high requirements of users for image stabilization performance during shooting. When the power is off, the return magnetic guide and the image stabilization magnet have an attraction force in a preset direction, which can accurately drive the moving body to move to the initial position along the preset direction, avoiding the moving body from deviating from the preset direction when the power is off, and ensuring that the motor can return to the ideal position close to the center when not driven, effectively improving the stability and reliability of the motor operation. Furthermore, by abandoning the traditional complex spring setting method, the internal structure is simplified and the size of the camera image stabilization drive motor is reduced, which is conducive to the miniaturization of the camera module.

[0006] In one possible implementation, the preset direction includes a first direction and a second direction that are perpendicular to each other. The number of the anti-shake drive structures is two sets, namely a first set of anti-shake drive structures and a second set of anti-shake drive structures. The aligning magnetic conductor of the first set of anti-shake drive structures is used to have an attractive force in the first direction with the corresponding anti-shake magnet when the power is off, so that the moving body moves along the first direction. The aligning magnetic conductor of the second set of anti-shake drive structures is used to have an attractive force in the second direction with the corresponding anti-shake magnet when the power is off, so that the moving body moves along the second direction.

[0007] In the solution provided in this application embodiment, by setting a first set of anti-shake driving structures and a second set of anti-shake driving structures, the moving body can be driven to move to the initial position along the first direction and the second direction, so as to avoid the moving body from deviating in the first direction and the second direction when the power is off.

[0008] In one possible implementation, the number of the aligning magnetic elements in the first group of anti-shake drive structures is two and they are spaced apart along the first direction. The number of the aligning magnetic elements in the second group of anti-shake drive structures is two and they are spaced apart along the second direction. The projections of the two aligning magnetic elements in the first group of anti-shake drive structures and the second group of anti-shake drive structures onto the corresponding anti-shake magnets are both centrally symmetrical with respect to the three-dimensional geometric center of the anti-shake magnets.

[0009] In the solution provided in this application embodiment, the symmetrically distributed structure enables the attraction of the two returning magnetic components to the anti-shake magnet to form a balanced force system, avoiding the eccentric torque caused by the concentration of attraction of a single magnetic component, ensuring that the moving body is stably subjected to force in the preset direction during the power-off return process, effectively reducing the tilting or offset trend that may occur during the return, and greatly improving the accuracy of the return position.

[0010] In one possible implementation, the number of the aligning magnetic conductors in both the first group of anti-shake drive structures and the second group of anti-shake drive structures is one. The projections of the two ends of the aligning magnetic conductor in the first group of anti-shake drive structures onto the corresponding anti-shake magnets along the first direction are centrally symmetrical with respect to the three-dimensional geometric center of the anti-shake magnets. The projections of the two ends of the aligning magnetic conductor in the second group of anti-shake drive structures onto the corresponding anti-shake magnets along the second direction are centrally symmetrical with respect to the three-dimensional geometric center of the anti-shake magnets.

[0011] In the solution provided in this application embodiment, the design of a single returning magnetic conductor simplifies the structural layout, reduces the number of parts, and facilitates further compression of the motor's internal space, better meeting the requirements of miniaturization. Simultaneously, its symmetrical distribution at both ends enables the attraction force on the anti-vibration magnet to form a balanced torque in a preset direction, avoiding return deviation caused by force point offset, ensuring that the moving body smoothly returns to center along the symmetrical axis when power is off, effectively guaranteeing return accuracy.

[0012] In one possible implementation, the base or the movable body has a receiving groove corresponding to the position of the aligning magnetic conductor, and the aligning magnetic conductor is disposed in the receiving groove; or the aligning magnetic conductor is integrally formed in the base or the movable body.

[0013] In the solution provided by this application embodiment, the receiving slot provides a precise installation and positioning space for the return magnetic guide component, ensuring that its relative position with the image stabilization coil and image stabilization magnet meets design requirements. Simultaneously, embedding the return magnetic guide component within the receiving slot further reduces the overall structural size, enhancing its miniaturization advantage. The integral molding of the return magnetic guide component into the base or moving body reduces the size of the base or moving body, which is beneficial for the miniaturization of the camera image stabilization drive motor.

[0014] In one possible implementation, the moving body has a receiving cavity, and the camera stabilization drive motor further includes a carrier and a focusing drive structure. The carrier is disposed in the receiving cavity and can move along a third direction perpendicular to the preset direction. The lens is mounted on the carrier, and the focusing drive structure is disposed on the moving body and the carrier respectively, for driving the carrier to move relative to the moving body.

[0015] In the solution provided in this application embodiment, the receiving cavity of the moving body provides a stable installation space for the carrier. The carrier can move along a third direction perpendicular to the preset direction, and the lens is installed on the carrier. This design enables the lens to achieve image stabilization (along the preset direction) while independently focusing (along the third direction), realizing the separation and coordination of image stabilization and focusing functions.

[0016] In one possible implementation, the focusing drive structure includes a focusing coil and a focusing magnet disposed opposite to each other, one of the focusing coil and the focusing magnet being disposed on the moving body, and the other of the focusing coil and the focusing magnet being disposed on the carrier.

[0017] In the solution provided in this application embodiment, the focusing coil and the focusing magnet are arranged opposite to each other, so that the electromagnetic force between the two can act directly on the carrier, reduce the loss in the driving force transmission process, ensure that the focusing driving force acts on the carrier efficiently, and realize the carrier's rapid and accurate movement in a third direction.

[0018] In one possible implementation, the base is provided with a plurality of protrusions, and the movable body is provided with a relief groove corresponding to the position of the protrusions, with the protrusions disposed in the relief groove.

[0019] In the solution provided in this application embodiment, multiple protrusions on the base are correspondingly disposed in the clearance groove of the moving body, forming a precise limiting structure, which can effectively constrain the movement range of the moving body along the preset direction, avoid the moving body from colliding or interfering with other components due to excessive displacement, and ensure the stability and safety of the internal structure of the motor.

[0020] A second aspect of this application provides a camera module, including a camera stabilization drive motor and a lens as described above, wherein the lens is mounted on the carrier.

[0021] The camera module provided in this application includes the aforementioned camera image stabilization drive motor. In the image stabilization drive structure, the image stabilization coil and the image stabilization magnet are respectively disposed on the base and the moving body and arranged opposite to each other. This design allows the image stabilization function to be achieved through the interaction of the image stabilization coil and the image stabilization magnet during normal operation, ensuring the stability and clarity of the image and meeting the high requirements of users for image stabilization performance during shooting. When power is off, the return magnetic guide and the image stabilization magnet have an attractive force in a preset direction, which can accurately drive the moving body to move to the initial position along the preset direction, preventing the moving body from deviating from the preset direction when power is off. This ensures that the motor can return to the ideal position close to the center when not driven, effectively improving the stability and reliability of the motor operation. Furthermore, by abandoning the traditional complex spring-loaded setting method, the internal structure is simplified, and the size of the camera image stabilization drive motor is reduced, which is beneficial to the miniaturization of the camera module.

[0022] A third aspect of this application provides an electronic device, including a housing; and a camera module as described above, the camera module being disposed in the housing.

[0023] The electronic device provided in this application includes the aforementioned camera image stabilization drive motor. In the image stabilization drive structure, the image stabilization coil and the image stabilization magnet are respectively disposed on the base and the moving body and arranged opposite to each other. This design allows the image stabilization function to be achieved through the interaction of the image stabilization coil and the image stabilization magnet during normal operation, ensuring the stability and clarity of the image and meeting the high requirements of users for image stabilization performance during shooting. When power is off, the return magnetic guide and the image stabilization magnet have an attractive force in a preset direction, which can accurately drive the moving body to move to the initial position along the preset direction, preventing the moving body from deviating from the preset direction when power is off. This ensures that the motor can return to the ideal position close to the center when not driven, effectively improving the stability and reliability of the motor operation. Furthermore, by abandoning the traditional complex spring-loaded setting method, the internal structure is simplified, and the size of the camera image stabilization drive motor is reduced, which is beneficial for the miniaturization of the camera module.

[0033] The following will describe some embodiments of this application in detail with reference to the accompanying drawings.

[0034] Please also see Figure 1 and Figure 2 The first aspect of this application provides a camera image stabilization drive motor 100, including a base 10, a movable body 20, a rolling element 30, and an image stabilization drive structure 40.

[0035] The base 10 is generally square in shape. The movable body 20 is disposed on the base 10 and can move in a preset direction. The rolling element 30 is disposed between the base 10 and the movable body 20. A portion of the rolling element 30 is rotatably accommodated within the base 10, and another portion of the rolling element 30 is rotatably accommodated within the movable body 20. In this embodiment, there are three rolling elements 30 arranged in a triangle between the base 10 and the movable body 20. Specifically, the rolling element 30 is a ball bearing. The image stabilization drive structure 40 includes an image stabilization coil 41, an image stabilization magnet 42, and a return magnetic guide 43. The image stabilization coil 41 and the image stabilization magnet 42 are arranged opposite to each other. One of the image stabilization coil 41 and the image stabilization magnet 42 is located on the base 10, and the other of the image stabilization coil 41 and the image stabilization magnet 42 is located on the moving body 20. The return magnetic guide 43 is arranged opposite to the image stabilization magnet 42. One of the return magnetic guide 43 and the image stabilization magnet 42 is located on the moving body 20, and the other of the return magnetic guide 43 and the image stabilization magnet 42 is located on the base 10. The return magnetic guide 43 is used to have an attractive force with the image stabilization magnet 42 in a preset direction when the power is off, so that the moving body 20 moves to the initial position in the preset direction. The initial position is the position of the moving body 20 when the camera image stabilization drive motor 100 is not working. In this embodiment, the anti-shake coil 41 is disposed on the base 10, the anti-shake magnet 42 is disposed on the moving body 20, and the return magnetic conductor 43 is disposed on the base 10. The anti-shake coil 41 and the return magnetic conductor 43 can be disposed on the base 10 simultaneously. It is understood that the anti-shake magnet 42 can be disposed on the base 10, and the anti-shake coil 41 and the return magnetic conductor 43 can be disposed on the moving body 20 simultaneously. However, it is not limited to this.

[0036] In the solution provided in this application embodiment, the anti-shake coil 41 and anti-shake magnet 42 in the anti-shake drive structure 40 are respectively disposed on the base 10 and the moving body 20, with the anti-shake coil 41 arranged opposite to each other. This design allows the anti-shake coil 41 and the anti-shake magnet 42 to interact and achieve the anti-shake function during normal operation, ensuring the stability and clarity of the image and meeting the user's high requirements for anti-shake performance during shooting. When the power is off, the return magnetic conductor 43 and the anti-shake magnet 42 have an attraction force in a preset direction, which can accurately drive the moving body 20 to move to the initial position along the preset direction, preventing the moving body 20 from deviating from the preset direction when the power is off, and ensuring that the motor can return to the ideal position close to the middle when not driven, effectively improving the stability and reliability of the motor operation. Furthermore, by abandoning the traditional complex spring setting method, the internal structure is simplified, and the size of the camera anti-shake drive motor 100 is reduced, which is conducive to the miniaturization of the camera module 300.

[0037] In one possible implementation, the preset direction includes a first direction and a second direction that are perpendicular to each other. In this embodiment, the first direction is the X-axis direction, and the second direction is the Y-axis direction. There are two sets of anti-shake drive structures 40, namely a first set and a second set. The return magnetic conductor 43 of the first set of anti-shake drive structures 40 is used to have an attractive force in the first direction with the corresponding anti-shake magnet 42 when power is off, so that the moving body 20 moves along the first direction. The return magnetic conductor 43 of the second set of anti-shake drive structures 40 is used to have an attractive force in the second direction with the corresponding anti-shake magnet 42 when power is off, so that the moving body 20 moves along the second direction.

[0038] In the solution provided in this application embodiment, by setting a first set of anti-shake driving structure 40 and a second set of anti-shake driving structure 40, the moving body 20 can be driven to move to the initial position along the first direction and the second direction, so as to avoid the moving body 20 from deviating in the first direction and the second direction when the power is off.

[0039] In one possible implementation, the first group of anti-shake drive structures 40 has two aligning magnetic conductors 43 spaced apart along a first direction, and the second group of anti-shake drive structures 40 also has two aligning magnetic conductors 43 spaced apart along a second direction. The projections of the two aligning magnetic conductors 43 in both the first and second groups of anti-shake drive structures 40 onto their respective anti-shake magnets 42 are both centrally symmetrical with respect to the geometric center of the anti-shake magnets 42. In this embodiment, each aligning magnetic conductor 43 is a long strip structure.

[0040] In the solution provided in this application embodiment, the symmetrically distributed structure enables the attraction between the two returning magnetic conductors 43 and the anti-shake magnet 42 to form a balanced force system, avoiding the eccentric torque caused by the concentration of attraction of a single magnetic conductor, ensuring that the moving body 20 is stably subjected to force in the preset direction during the power-off return process, effectively reducing the tilting or offset trend that may occur during the return, and greatly improving the accuracy of the return position.

[0041] Please see also Figure 3 In one possible implementation, the number of return magnetic conductors 43 in both the first and second sets of anti-shake drive structures 40 is one. The projections of the two ends of the return magnetic conductor 43 along the first direction onto the corresponding anti-shake magnet 42 are centrally symmetrical with respect to the geometric center of the anti-shake magnet 42. Similarly, the projections of the two ends of the return magnetic conductor 43 along the second direction onto the corresponding anti-shake magnet 42 are centrally symmetrical with respect to the geometric center of the anti-shake magnet 42. In this embodiment, the return magnetic conductor 43 is a long strip structure.

[0042] In the solution provided in this application embodiment, the design of a single returning magnetic conductor 43 simplifies the structural layout, reduces the number of parts, and facilitates further compression of the motor's internal space, better meeting the requirements of miniaturization. Simultaneously, its symmetrical distribution at both ends enables the attraction force on the anti-vibration magnet 42 to form a balanced torque in a preset direction, avoiding return deviation caused by force point offset, ensuring that the moving body 20 smoothly returns to center along the symmetrical axis when power is off, effectively guaranteeing return accuracy.

[0043] Please continue reading Figure 2 In one possible implementation, the base 10 or the movable body 20 has a receiving groove 12 corresponding to the position of the return magnetic conductor 43, and the return magnetic conductor 43 is disposed in the receiving groove 12; or the return magnetic conductor 43 is integrally formed in the base 10 or the movable body 20. In this embodiment, the receiving groove 12 is formed on the side of the base 10 near the movable body 20. It can be understood that the receiving groove 12 can be formed in the movable body 20. In some embodiments, the return magnetic conductor 43 can be injection molded in the base 10 or the movable body 20.

[0044] In the solution provided in this application embodiment, the receiving groove 12 provides a precise installation and positioning space for the return magnetic guide 43, ensuring that its relative position with the image stabilization coil 41 and the image stabilization magnet 42 meets the design requirements. Simultaneously, embedding the return magnetic guide 43 within the receiving groove 12 further compresses the overall structural size, enhancing its miniaturization advantage. The integral molding of the return magnetic guide 43 within the base 10 or the moving body 20 can compress the size of the base 10 or the moving body 20, which is beneficial for the miniaturization of the camera image stabilization drive motor 100.

[0045] In one possible implementation, the moving body 20 has a receiving cavity 21, and the camera stabilization drive motor 100 further includes a carrier 50 and a focusing drive structure 60. The carrier 50 is disposed in the receiving cavity 21 and can move along a third direction perpendicular to a preset direction. The lens 200 is mounted on the carrier 50, and the focusing drive structure 60 is disposed on both the moving body 20 and the carrier 50, for driving the carrier 50 to move relative to the moving body 20. In this embodiment, the third direction is the Z-axis direction.

[0046] In the solution provided in this application embodiment, the receiving cavity 21 of the moving body 20 provides a stable installation space for the carrier 50. The carrier 50 can move along a third direction perpendicular to the preset direction, and the lens 200 is installed on the carrier 50. This design enables the lens 200 to achieve image stabilization (along the preset direction) while independently focusing (along the third direction), realizing the separation and coordination of image stabilization and focusing functions.

[0047] In one possible implementation, the focusing drive structure 60 includes a focusing coil 61 and a focusing magnet 62 disposed opposite to each other. One of the focusing coil 61 and the focusing magnet 62 is disposed on the movable body 20, and the other of the focusing coil 61 and the focusing magnet 62 is disposed on the carrier 50. In this embodiment, the focusing coil 61 is disposed on the movable body 20, and the focusing magnet 62 is disposed within the carrier 50. It can be understood that the focusing magnet 62 can be disposed on the movable body 20, and the focusing coil 61 can be disposed on the carrier 50.

[0048] In the solution provided in this application embodiment, the focusing coil 61 and the focusing magnet 62 are arranged opposite to each other, so that the electromagnetic force between the two can act directly on the carrier 50, reduce the loss in the driving force transmission process, ensure that the focusing driving force acts efficiently on the carrier 50, and realize the rapid and accurate movement of the carrier 50 in a third direction.

[0049] In one possible implementation, the base 10 is provided with a plurality of protrusions 11, and the movable body 20 is provided with a relief groove 22 corresponding to the position of the protrusions 11, with the protrusions 11 disposed in the relief groove 22. In this embodiment, there are four protrusions 11, which are respectively disposed at the four corners of the base 10, and correspondingly, there are also four relief grooves 22.

[0050] In the solution provided in this application embodiment, multiple protrusions 11 on the base 10 are correspondingly disposed in the clearance groove 22 of the moving body 20, forming a precise limiting structure, which can effectively constrain the movement range of the moving body 20 along the preset direction, avoid the moving body 20 from colliding or interfering with other components due to excessive displacement, and ensure the stability and safety of the internal structure of the motor.

[0051] In one possible implementation, the camera stabilization drive motor 100 further includes a guide member 70, which is disposed between the moving body 20 and the carrier 50. The guide member 70 is fixedly connected to the moving body 20 and slidably connected to the carrier 50. In this embodiment, the guide member 70 has a columnar structure, and there are two guide members 70, which are disposed in the focusing direction of the moving body 20.

[0052] In one possible implementation, the camera stabilization drive motor 100 further includes a cover 80, which is disposed on the base 10 and covers the outer periphery of the movable body 20 and the carrier 50.

The image stabilization coil 41 and image stabilization magnet 42 in the image stabilization drive structure 40 of the camera image stabilization drive motor 100 are respectively disposed on the base 10 and the moving body 20, with the image stabilization coil 41 facing each other. This design allows the image stabilization function to be achieved through the interaction of the image stabilization coil 41 and the image stabilization magnet 42 during normal operation, ensuring the stability and clarity of the image and meeting the high requirements of users for image stabilization performance during shooting. When power is off, the return magnetic conductor 43 and the image stabilization magnet 42 have an attractive force in a preset direction, which can accurately drive the moving body 20 to move to the initial position along the preset direction, preventing the moving body 20 from deviating from the preset direction when power is off. This ensures that the motor can return to the ideal position close to the center when not driven, effectively improving the stability and reliability of the motor operation. Furthermore, by abandoning the traditional complex spring setting method, the internal structure is simplified, and the size of the camera image stabilization drive motor 100 is reduced, which is beneficial to the miniaturization of the camera module 300.
