Description

Technical Field

[0001] This application relates to the field of camera technology, and more particularly to a stabilization motor and electronic device. Background Technology

[0002] The image stabilization motor in a camera is a key component of the lens system. Its core function is to effectively compensate for deviations caused by camera shake during shooting, thereby achieving stable and clear imaging results. Image stabilization motors typically operate based on electromagnetic or optical principles. Taking an electromagnetic image stabilization motor as an example, its working principle is to drive the image stabilization components to make corresponding displacements by precisely controlling the magnitude and direction of the current in the coils within the motor in a stable magnetic field environment.

[0003] When the device detects shaking, the system quickly calculates the direction and magnitude of the shaking and immediately sends a command to the motor. By changing the coil current, an electromagnetic force of specific direction and magnitude is generated. This electromagnetic force pushes image stabilization components, such as optical lens groups, to move or tilt within a certain range, thereby counteracting the effects of shaking and ensuring that light is accurately focused on the image sensor. This ultimately achieves image stabilization, providing a solid technical guarantee for capturing high-quality, stable images.

[0004] In existing technologies, the movement and positioning of the image stabilization component within the housing primarily rely on multiple sets of ball bearings and guide rails to support and control its movement. However, the guide rails require extremely high precision, making it difficult to achieve high precision standards not only during manufacturing but also during assembly. This results in inconsistent alignment between the guide rails, causing the image stabilization component to jam, shift, or fail to accurately reset during movement. These problems severely impact the lens's stabilization performance and final image quality, leading to blurry images and ghosting. Utility Model Content

[0013] In one possible implementation, the sixth groove is a rectangular groove, with its long side extending along the second direction and its wide side extending along the first direction.

[0014] In one possible implementation, the third groove is a square groove, the first side of the third groove extends along the first direction, the second side of the third groove extends along the second direction, and the length of the first side of the third groove is greater than the length of the wide side of the sixth groove.

[0023] Compared with the prior art, the beneficial effects of this application are as follows:

[0024] In the anti-shake motor and electronic device provided in this application, the movable part and the fixed part are movably connected. The first groove and the second groove are perpendicular to each other and arranged opposite to each other. The first groove extends along a first direction, and the second groove extends along a second direction, with the first direction perpendicular to the second direction. A portion of the first rolling member is placed in the first groove, and the other portion is placed in the second groove, allowing the first rolling member to move along the first direction under the constraint of the first groove and along the second direction under the constraint of the second groove. This achieves guiding movement of the movable part in two perpendicular directions, providing a precise movement path for the anti-shake adjustment of the anti-shake motor. The third groove and the fourth groove are arranged opposite to each other, with a portion of the second rolling member located in the third groove and the other portion located in the fourth groove. The dimensions of the third groove and the fourth groove in both the first and second directions are larger than the diameter of the second rolling member, giving the second rolling member a certain amount of room to move within the third groove and the fourth groove. This allows it to support the movable part while accommodating small movements of the movable part in different directions, playing a role in buffering and stabilizing support.

[0025] The first guide structure, through the cooperation of the mutually perpendicular first and second grooves and the first rolling element, provides high-precision guidance for the movable part. During the anti-shake process, the movable part can move precisely along two perpendicular directions, thereby more accurately compensating for deviations caused by vibration and improving the anti-shake accuracy of the anti-shake motor. The design of the third and fourth grooves and the second rolling element in the first support structure provides stable support for the movable part, ensuring its stability during movement, while also allowing for minute movements within a certain range. This avoids limitations in movement, jamming, or offset caused by manufacturing precision errors, helping to extend the service life of the anti-shake motor and improve its reliability.

[0045] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0046] In this application, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0047] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0048] The image stabilization motor in a camera is a key component of the lens system. Its core function is to effectively compensate for deviations caused by camera shake during shooting, thereby achieving stable and clear imaging results. Image stabilization motors typically operate based on electromagnetic or optical principles. Taking an electromagnetic image stabilization motor as an example, its working principle is to drive the image stabilization components to make corresponding displacements by precisely controlling the magnitude and direction of the current in the coils within the motor in a stable magnetic field environment.

[0049] When the device detects shaking, the system quickly calculates the direction and magnitude of the shaking and immediately sends a command to the motor. By changing the coil current, an electromagnetic force of specific direction and magnitude is generated. This electromagnetic force pushes image stabilization components, such as optical lens groups, to move or tilt within a certain range, thereby counteracting the effects of shaking and ensuring that light is accurately focused on the image sensor. This ultimately achieves image stabilization, providing a solid technical guarantee for capturing high-quality, stable images.

[0050] In existing technologies, the movement and positioning of the image stabilization component within the housing primarily rely on multiple sets of ball bearings and guide rails to support and control its movement. However, the guide rails require extremely high precision, making it difficult to achieve high precision standards not only during manufacturing but also during assembly. This results in inconsistent alignment between the guide rails, causing the image stabilization component to jam, shift, or fail to accurately reset during movement. These problems severely impact the lens's stabilization performance and final image quality, leading to blurry images and ghosting.

[0051] In view of this, some embodiments of this application provide a stabilization motor and electronic device that can provide high-precision guidance for the movable part, improve the stabilization accuracy of the stabilization motor, and avoid motion restriction, jamming, or offset caused by manufacturing precision errors, thereby helping to extend the service life of the stabilization motor and improve its reliability.

[0052] The present application will be described in detail below through specific embodiments:

[0053] The anti-shake motor in the embodiments of this application, such as Figures 1-12 As shown, the image stabilization motor includes:

[0054] The fixing part 10 has a first surface 11;

[0055] The movable part 20 is movably connected to the fixed part 10. The movable part 20 has a second surface 21, which is disposed opposite to the first surface 11.

[0056] The first guide structure 30 includes a first rolling element 31, a first groove 32, and a second groove 33. The first groove 32 and the second groove 33 are perpendicular to each other and arranged opposite to each other. The first groove 32 is disposed on the first surface 11, and the second groove 33 is disposed on the second surface 21. The first groove 32 extends along a first direction, and the second groove 33 extends along a second direction. A portion of the first rolling element 31 is disposed in the first groove 32, which guides the first rolling element 31 along the first direction. The other portion of the first rolling element 31 is disposed in the second groove 33, which guides the first rolling element 31 along the second direction. The first direction is perpendicular to the second direction.

[0057] The first support structure 40 includes a second rolling element 41, a third groove 42, and a fourth groove 43. The third groove 42 and the fourth groove 43 are disposed opposite to each other. The third groove 42 is disposed on the first surface 11, and the fourth groove 43 is disposed on the second surface 21. A portion of the second rolling element 41 is located in the third groove 42. The dimensions of the third groove 42 in both the first and second directions are larger than the diameter of the second rolling element 41. The other portion of the second rolling element 41 is located in the fourth groove 43. The dimensions of the fourth groove 43 in both the first and second directions are larger than the diameter of the second rolling element 41.

[0058] The anti-shake motor provided in this application embodiment has a movable part 20 movably connected to a fixed part 10. The first groove 32 and the second groove 33 are perpendicular to each other and arranged opposite to each other. The first groove 32 extends along a first direction, and the second groove 33 extends along a second direction. The first direction is perpendicular to the second direction. A portion of the first rolling member 31 is placed in the first groove 32, and the other portion is placed in the second groove 33. This allows the first rolling member 31 to move along the first direction under the constraint of the first groove 32 and along the second direction under the constraint of the second groove 33. This enables the movable part 20 to guide movement in two perpendicular directions, providing a precise movement path for the anti-shake adjustment of the anti-shake motor. The third groove 42 and the fourth groove 43 are arranged opposite to each other. Part of the second rolling element 41 is located in the third groove 42 and the other part is located in the fourth groove 43. The dimensions of the third groove 42 and the fourth groove 43 in the first and second directions are both larger than the diameter of the second rolling element 41, so that the second rolling element 41 has a certain amount of room to move in the third groove 42 and the fourth groove 43. It can support the movable part 20 while adapting to the slight movement of the movable part 20 in different directions, and play a role in buffering and stabilizing support.

[0059] The first guide structure 30, through the cooperation of the mutually perpendicular first groove 32 and second groove 33 and the first rolling element 31, provides high-precision guidance for the movable part 20. During the anti-shake process, the movable part 20 can move precisely along two perpendicular directions, thereby more accurately compensating for deviations caused by shaking and improving the anti-shake accuracy of the anti-shake motor. The design of the third groove 42 and fourth groove 43 and the second rolling element 41 in the first support structure 40 can provide stable support for the movable part 20, ensuring the stability of the movable part 20 during movement, and also allow the movable part 20 to make small movements within a certain range. This avoids movement restrictions, jamming, or offset caused by manufacturing precision errors, which helps to extend the service life of the anti-shake motor and improve its reliability.

[0060] It should be explained that the image stabilization motor of this application is used in a camera module. The fixed part 10 is the housing of the image stabilization motor, and the movable part 20 is the lens mount of the image stabilization motor. The lens mount is movably connected to the housing. The first surface 11 is the bottom shell surface of the housing facing the lens mount, and the second surface 21 is the lens mount surface facing the bottom shell of the housing. The second surface 21 and the first surface 11 are arranged opposite each other along the optical axis of the lens. The first groove 32 and the second groove 33 are arranged opposite each other along the optical axis of the lens, and the third groove 42 and the fourth groove 43 are arranged opposite each other along the optical axis of the lens. The first rolling element 31 and the second rolling element 41 are both ball bearings.

[0061] In the diagram, the X direction is the optical axis of the lens, the Y direction is the first direction, and the Z direction is the second direction.

[0062] It's important to explain that the optical axis is a crucial reference line in an optical system. It's a virtual straight line passing through the center of the optical system (such as a lens). In an ideal optical system, light rays propagate and refract along the optical axis or about the optical axis as an axis of symmetry. During imaging, the distribution and propagation path of light rays around the optical axis determine key factors such as the position, size, and quality of the image. The direction of the optical axis refers to the direction it points to. In practical applications, the optical axis direction is usually from the object side (the side of the object being observed or photographed) to the image side (the side of the image formed). For example, in a camera lens, the optical axis direction is from the object being photographed to the imaging sensor inside the camera.

[0063] Furthermore, such as Figure 2As shown, the image stabilization motor also includes a second guide structure 50, which includes a third rolling element 51, a fifth groove 52, and a sixth groove 53. The fifth groove 52 and the sixth groove 53 are arranged opposite to each other along the optical axis of the lens. The fifth groove 52 is disposed on the first surface 11, and the sixth groove 53 is disposed on the second surface 21. The fifth groove 52 extends along the first direction. A portion of the third rolling element 51 is disposed in the fifth groove 52. The fifth groove 52 is used to guide the third rolling element 51 along the first direction, and another portion of the third rolling element 51 is disposed in the sixth groove 53. The dimensions of the sixth groove 53 in both the first and second directions are larger than the diameter of the third rolling element 51.

[0064] The fifth groove 52 of the second guide structure 50 guides the third rolling element 51 along the first direction, further improving the accuracy of the movable part 20's movement in the first direction. During lens stabilization, more precise guidance allows the movable part 20 to more accurately compensate for deviations in the first direction caused by shaking, thereby improving the clarity and stability of the captured image. The sixth groove 53 is larger than the diameter of the third rolling element 51 in both the first and second directions, allowing the third rolling element 51 some room to move and permitting a slight offset of the movable part 20 in both directions, thus adapting to different stabilization adjustment needs. The second guide structure 50, the first guide structure 30, and the first support structure 40 work together to make the movable part 20 more stable during movement, dispersing the forces acting on the movable part 20 during movement, reducing instability caused by uneven force on individual structures, and lowering the possibility of the movable part 20 shaking or getting stuck.

[0065] In other embodiments, the image stabilization motor may also include a second guide structure 50, which includes a third rolling element 51, a fifth groove 52, and a sixth groove 53. The fifth groove 52 and the sixth groove 53 are arranged opposite to each other along the optical axis of the lens. The fifth groove 52 is disposed on the first surface 11, and the sixth groove 53 is disposed on the second surface 21. The fifth groove 52 extends along the second direction. A portion of the third rolling element 51 is disposed in the fifth groove 52, which guides the third rolling element 51 along the second direction. Another portion of the third rolling element 51 is disposed in the sixth groove 53. The dimensions of the sixth groove 53 in both the first and second directions are larger than the diameter of the third rolling element 51.

[0066] Alternatively, in other embodiments, the second guide structure 50 may also include a fifth groove 52 and a fourth guide groove that are perpendicular to each other, the fifth groove 52 being used to guide the third rolling element 51 along a first direction, and the fourth guide groove being used to guide the third rolling element 51 along a second direction.

[0067] In this application, the third rolling element 51 is also a ball bearing.

[0068] Specifically, in some embodiments, such as Figure 12 As shown, the sixth groove 53 is a rectangular groove, with its long side extending along the second direction and its wide side extending along the first direction.

[0069] Because the fifth groove 52 guides the third rolling element 51 along the first direction, and extends the wide side of the sixth groove 53 along the first direction and the long side of the sixth groove 53 along the second direction, the sixth groove 53 allows the third rolling element 51 to have a certain amount of slight movement in the first direction, while preventing the movable part 20 from moving too freely in that direction and losing control, thus ensuring a balance between the flexibility and controllability of the movable part 20's movement in the first direction. This makes the movement of the third rolling element 51 more precise in the first direction, while its movement in the second direction is more flexible, providing auxiliary guidance to the first guide structure 30. The cooperation between the first guide structure 30 and the second guide structure 50 not only accurately compensates for lens deviations caused by camera shake, but also prevents the movement process from becoming too choppy, improving the stability and clarity of the captured image.

[0070] Furthermore, in one possible implementation, the third groove 42 is a square groove, the first side of the third groove 42 extends along a first direction, the second side of the third groove 42 extends along a second direction, and the length of the first side of the third groove 42 is greater than the length of the wide side of the sixth groove 53.

[0071] For example, such as Figure 11 and Figure 12 As shown, the fourth groove 43 is a square groove, the third side of the fourth groove 43 extends along the first direction, the fourth side of the fourth groove 43 extends along the second direction, and the length of the third side L1 of the fourth groove 43 is greater than the length of the wide side L3 of the sixth groove 53.

[0072] The square third groove 42 and fourth groove 43 provide the second rolling element 41 with a relatively balanced range of motion in the first and second directions, allowing the movable part 20 to move more significantly in both directions. Since the side lengths of the third groove 42 and fourth groove 43 are greater than the width of the sixth groove 53, the movable part 20 can have a greater displacement within the range defined by these two receiving grooves. This allows the first support structure 40 to work in conjunction with the first guide structure 30 and the second guide structure 50. The first guide structure 30 provides precise guidance, the second guide structure 50 provides auxiliary guidance, and the third groove 42 and fourth groove 43 of the first support structure 40 provide flexible support and movement space. This allows the movable part 20 to make appropriate adjustments based on vibration while providing precise guidance, avoiding jamming and achieving a more efficient and precise anti-vibration effect.

[0073] In other possible implementations, the sixth groove 53 can also be set as a square groove, or the third groove 42 and the fourth groove 43 can also be set as rectangular grooves.

[0074] In this embodiment, as Figure 4 and Figure 8 As shown, the first groove 32 includes a first groove wall 321 and a second groove wall 322 extending along a first direction. The first groove wall 321 and the second groove wall 322 are inclined relative to the first groove bottom 323 of the first groove 32. The angle between the first groove wall 321 and the first groove bottom 323 is α, and the angle between the second groove wall 322 and the first groove bottom 323 is β. Both α and β are obtuse angles. The first rolling element 31 rolls in cooperation with the first groove bottom 323, the first groove wall 321 and the second groove wall 322 along the first direction.

[0075] Similarly, as Figure 10 As shown, the second groove 33 includes a third groove wall 331 and a fourth groove wall 332 extending along the second direction. The third groove wall 331 and the fourth groove wall 332 are inclined relative to the second groove bottom 333 of the second groove 33. The included angles between the third groove wall 331 and the fourth groove wall 332 and the second groove wall 322 are both obtuse angles. The first rolling member 31 rolls in cooperation with the second groove bottom 333, the third groove wall 331 and the fourth groove wall 332 along the second direction.

[0076] The inclined first groove wall 321 and second groove wall 322 give the cross-section of the first groove 32 a shape that is wider at the top and narrower at the bottom. This guide groove structure, which is wider at the top and narrower at the bottom, makes it easier for the first rolling element 31 to be placed into the groove during assembly. At the same time, the first rolling element 31 rolls in cooperation with the first groove bottom 323, the first groove wall 321 and the second groove wall 322 in the first direction. The first groove wall 321 and the second groove wall 322 can constrain the first rolling element 31, ensuring that the first rolling element 31 will not easily detach from the first groove 32 when sliding in the first direction. The contact method between the inclined groove wall and the first rolling element 31 makes the friction force distribution more uniform, ensuring the stability and reliability of the entire anti-shake structure.

[0077] Similarly, the first rolling element 31 rolls in cooperation with the second groove bottom 333, the third groove wall 331 and the fourth groove wall 332 in the second direction. The third groove wall 331 and the fourth groove wall 332 can constrain the first rolling element 31 to ensure that the first rolling element 31 will not easily disengage from the second groove 33 when sliding in the second direction. During the movement of the movable part 20, the first rolling element 31 may experience different motion states such as acceleration and deceleration. The inclined groove wall can better adapt to these changes, provide stable support and guidance for the first rolling element 31, and ensure that the movable part 20 achieves effective anti-shaking.

[0078] Furthermore, such as Figure 6 As shown, the fifth groove 52 includes a fifth groove wall 521 and a sixth groove wall 522 extending along the first direction. The fifth groove wall 521 and the sixth groove wall 522 are inclined relative to the third groove bottom 523 of the fifth groove 52. The included angles between the fifth groove wall 521 and the sixth groove wall 522 and the third groove bottom 523 are both obtuse angles. The third rolling member 51 rolls in cooperation with the third groove bottom 523, the fifth groove wall 521 and the sixth groove wall 522 along the first direction.

[0079] The third rolling element 51 contacts the third groove bottom 523, the fifth groove wall 521, and the sixth groove wall 522, which can constrain the third rolling element 51 from multiple directions, making the movement of the third rolling element 51 more precise in the first direction. The inclined groove wall can provide a certain buffer and support when the third rolling element 51 slides, making the movable part 20 more stable during movement. At the same time, this inclined groove wall has higher processing precision and is easier to achieve consistency with other guide grooves, ensuring a good guiding effect and reducing jamming during movement.

[0080] In other embodiments, the first groove 32, the second groove 33 and the fifth groove 52 may also be arc-shaped grooves, which fit with the corresponding rolling elements to achieve guiding sliding.

[0081] In one possible implementation, such as Figure 4 As shown, the first surface 11 is a square plane, and the first groove 32, the third groove 42 and the fifth groove 52 are respectively located at the three vertices of the first surface 11.

[0082] The three components are located at the three vertices of the square plane. The distribution of the vertices can make the support and guidance of each structure on the movable part 20 more balanced. During the movement of the movable part 20, the components at the three vertices can provide stable forces from different directions, reducing the possibility of the movable part 20 tilting or twisting during the movement. This allows for more comprehensive control of the movement of the movable part 20 in the plane and achieves efficient anti-shake function.

[0083] In other possible implementations, the first groove 32, the third groove 42, and the fifth groove 52 can also be located at the middle of each side of the square plane, so that the components are more balanced and the stability of the movement of the movable part 20 is guaranteed.

[0084] In some embodiments, such as Figure 4 As shown, the first groove 32 and the fifth groove 52 are arranged along the diagonal of the first surface 11.

[0085] Both the first groove 32 and the fifth groove 52 are responsible for guiding the movable part 20 in the first direction. The diagonal arrangement allows them to apply guiding force to the movable part 20 from two different diagonal directions. This distribution can more comprehensively constrain the movement of the movable part 20 in the first direction. The symmetrical layout of the two guide grooves makes the movable part 20 more balanced when subjected to force, avoiding the movable part 20 from deviating or shaking.

[0086] In one possible implementation, the dimensions of the first groove 32, the third groove 42, and the fifth groove 52 are the same along the first direction, for example, as shown below. Figure 10 -like Figure 12 As shown, along the second direction, the dimensions L5 of the second groove 33, L2 of the fourth groove 43, and L4 of the sixth groove 53 are the same, and the diameters D3 of the first rolling element 31, D1 of the second rolling element 41, and D2 of the third rolling element 51 are the same.

[0087] In the first direction, the first groove 32, the third groove 42, and the fifth groove 52 are spatially consistent, enabling them to apply a more stable and balanced force to the movable part 20. In the second direction, the second groove 33, the fourth groove 43, and the sixth groove 53 are the same size. The second groove 33, in conjunction with the first groove 32, guides the movable part 20 in the second direction. The fourth groove 43, together with the third groove 42, provides support for the movable part 20. The sixth groove 53, in cooperation with the fifth groove 52, ensures a relatively uniform distribution of the force and range of action of each component on the movable part 20 in the second direction, which is beneficial for the smooth movement of the movable part 20 in the second direction. When the movable part 20 is adjusted for anti-shake, the first groove 32, the third groove 42, and the fifth groove 52 simultaneously apply force to the movable part 20 in the first direction, while the second groove 33, the fourth groove 43, and the sixth groove 53 work together in the second direction, enabling the movable part 20 to move accurately along a predetermined trajectory, thus improving the response speed and accuracy of the anti-shake system.

[0088] This application also discloses an electronic device including a stabilization motor. The stabilization motor in this electronic device is the stabilization motor described above. Therefore, the electronic device in this embodiment has roughly the same technical effect as the stabilization motor described above. Since the technical effect of the stabilization motor has been fully explained, it will not be repeated here.

[0089] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
