Description

Technical Field

[0001] This utility model relates to the field of cameras, and more specifically, to an optical image stabilization component, a motor, a camera, and an electronic device. Background Technology

[0002] Traditional periscope camera optical image stabilization components suffer from several unresolved issues. The most prominent is that their rotation center does not coincide with the optical center. This design flaw prevents optimal lens adjustment during stabilization, thus impacting final image quality. Furthermore, traditional components often use ball bearings as suspension structures. While this allows for rotation, the friction between the ball bearings and the plastic material over time easily leads to wear and tear. This not only reduces the component's durability but may also cause a decrease in precision, further affecting stabilization effectiveness and image quality. Utility Model Content

[0003] In view of this, the present invention provides an optical image stabilization component with two rotating parts, the rotation centers of which are aligned with the optical center. This effectively enhances the image stabilization effect of the motor, reduces blurring, and improves image quality. Furthermore, the suspension design of the second rotating part ensures frictionless rotation, resulting in smooth and precise movement, guaranteeing lens stability and accuracy, and providing an excellent shooting experience.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] An optical image stabilization component, mounted on a base and used to support a lens, includes a first rotating part, a second rotating part, a Y-axis power unit, and a Z-axis power unit. The first rotating part has cylinders on both sides and can rotate relative to the base around the Y-axis with the cylinders as its rotation center under the action of the Y-axis power unit. The second rotating part is suspended from the first rotating part by a wire or elastic element and can rotate relative to the first rotating part around the Z-axis under the action of the Z-axis power unit. The rotation centers of both the first and second rotating parts are aligned with the optical center of the lens.

[0006] The two sides of the first rotating part are provided with cylinders, which provide support for the rotation of the first rotating part and serve as the rotation center of the first rotating part. Through fine adjustment of the position of the cylinder, the rotation center of the first rotating part can be accurately aligned with the optical center of the lens. As for the second rotating part, it adopts a suspended design and is supported by a wire or elastic element suspension scheme. This suspension scheme gives the second rotating part relative independence in space, and its rotation center can be easily adjusted to be consistent with the optical center of the lens when performing Rolling rotation, i.e., rotation along the Z-axis. The cylinder can be made of metal, and the friction experienced by the first rotating part during rotation can be reduced by polishing the metal surface or by adding dry lubricating oil.

[0007] The rotation center of the first rotating part and the rotation center of the second rotating part are highly consistent with the optical center of the lens, which can maximize the anti-shake effect of the motor. During actual shooting, when the camera or other imaging devices shake, this component can quickly and accurately adjust the position of the lens to ensure that light always enters the lens along the ideal path, effectively reducing the blur caused by shaking and significantly improving the imaging quality, providing users with a clear and sharp visual experience.

[0008] In addition, the wire or elastic element suspension scheme used in this scheme is a major breakthrough over traditional designs. Through this unique suspension method, the second rotating part does not generate additional friction when rotating along the Z-axis. This feature makes the movement of the second rotating part smoother and more accurate during rotation, effectively reducing control errors. Whether shooting static objects or capturing dynamic moments, the stability and accuracy of the lens can be ensured, providing users with an outstanding shooting experience.

[0009] Preferably, the second rotating part is suspended from the first rotating part by four wires or elastic elements.

[0010] The suspension layout of the four wires or elastic elements can provide uniform and stable support force for the second rotating part. During the rotation of the second rotating part around the Z-axis, this uniform support force distribution can effectively prevent shaking or deviation caused by uneven force, ensuring high-precision execution of the rotation action. Compared with traditional suspension methods, this design greatly improves the rotation stability of the second rotating part, enabling the lens to adjust the angle more smoothly during Rolling rotation, thereby further improving the clarity and stability of the image. By adjusting the positions of the four wires or elastic elements so that their center lines are consistent with the optical center of the lens, the rotation center of the second rotating part can be kept consistent with the optical center of the lens.

[0011] Preferably, the second rotating part is provided with connecting pieces on both sides, and the middle section of the wire or elastic member is connected to the connecting pieces, and both ends of the wire or elastic member are connected to the first rotating part.

[0012] The connecting pieces provide a stable connection point between the wire or elastic member and the second rotating part, and when the second rotating part rotates around the Z-axis under the action of the Z-axis power unit, the connecting pieces can make the force exerted by the wire or elastic member on the second rotating part more evenly and reasonably distributed. The middle section of the wire or elastic member is connected to the connecting pieces, and both ends are connected to the first rotating part, forming a stable mechanical structure. During rotation, the force can be evenly transmitted to the first rotating part along the wire or elastic member through the connecting pieces, avoiding deformation or damage caused by excessive local stress. This optimized force transmission and distribution mechanism not only helps to improve the rotation accuracy of the second rotating part, but also prolongs the service life of the wire or elastic member and the entire optical anti-shake assembly, ensuring that it always maintains good performance during long-term use. The presence of the connecting pieces also makes the installation of the wire or elastic member more convenient and accurate.

[0013] Preferably, the second rotating part is suspended from the first rotating part by four wires, and the wires are welded or glued to the embedded metal of the first and second rotating parts.

[0014] The welding or gluing method can form a firm connection between the wire and the embedded metal of the first and second rotating parts. During welding, the metal materials are fused together at high temperature to form a whole structure. This connection method has very high strength and stability and can withstand a large external force without loosening or falling off. Gluing fixation is to tightly combine the wire and the embedded metal through the viscosity of the glue. The glue fills the small gap between them, not only increasing the contact area, but also effectively preventing external factors from interfering with the connection part, ensuring that the connection between the wire and the rotating part is still stable and reliable in various complex working environments, such as vibration, impact or large temperature changes. This provides a solid guarantee for the stable suspension of the second rotating part.

[0015] Preferably, the second rotating part is suspended from the first rotating part by four elastic members, and the elastic members are riveted to the first and second rotating parts by rivets.

[0016] The elastic piece can increase the toughness during falling and improve the anti-falling capability. The riveting mode provides a very stable connection between the elastic piece and the first rotating part and the second rotating part. During the riveting process, the rivet column passes through the corresponding parts of the elastic piece and the rotating part, and then a firm combination is formed through riveting deformation. Even in the long-term use process, in the face of frequent vibration, impact and complex working environment, the riveting structure can still maintain a close connection state, ensuring that the elastic piece and the rotating part will not be loose, fall off and other problems, thereby providing reliable protection for the stable suspension of the second rotating part, and greatly prolonging the service life of the optical anti-shake assembly.

[0017] Preferably, the Y-axis power unit comprises a Y-axis coil and a Y-axis magnet, the Y-axis coil is arranged on the base, and the Y-axis magnet is arranged on the first rotating part; the Z-axis power unit comprises a Z-axis coil and a Z-axis magnet, the Z-axis coil is arranged on the base, and the Z-axis magnet is arranged on the second rotating part.

[0018] The Y-axis power unit and the Z-axis power unit adopt the combination mode of coils and magnets, realizing efficient conversion of electric energy into mechanical energy. When the current passes through the Y-axis coil, a magnetic field is generated, which interacts with the magnetic field of the Y-axis magnet, thereby generating a Lorentz force to drive the first rotating part to rotate around the Y-axis. Similarly, the interaction between the Z-axis coil and the Z-axis magnet can drive the second rotating part to rotate around the Z-axis. This power transmission mode based on the principle of electromagnetic induction has high energy conversion efficiency, can rapidly and effectively convert electric energy into mechanical energy required for rotary motion, so that the optical anti-shake assembly can quickly respond to the shaking of the device and timely adjust the position of the lens, ensuring the clarity and stability of imaging.

[0019] Another implementation mode of the utility model is a motor comprising the optical anti-shake assembly as described above.

[0020] Preferably, the base is provided with a supporting groove matched with the cylinder.

[0021] The supporting groove is in V shape, used for supporting the cylinder, so that the frictional resistance received by the first rotating part during rotation is smaller.

[0022] Another implementation mode of the utility model is a camera comprising the motor as described above.

[0023] Another implementation mode of the utility model is an electronic device comprising the camera as described above.

[0024] The utility model has the beneficial effects compared with the prior art:

[0025] The optical anti-shake assembly of the utility model, the two sides of the first rotating part are provided with a cylinder, which provides support for the rotation of the first rotating part and serves as the rotation center of the first rotating part, and through fine adjustment of the position of the cylinder, the rotation center of the first rotating part can be accurately made to coincide with the optical center of the lens. As for the second rotating part, because it adopts a suspended design and is supported through a wire or elastic piece suspension scheme, the suspension scheme gives the second rotating part relative independence in space, and when rolling rotation, that is, rotation along the Z axis, is performed, the rotation center can also be very easily adjusted to be consistent with the optical center of the lens. The cylinder can be made of metal, and the friction force experienced by the first rotating part during rotation can be reduced through polishing of the metal surface, or the friction force can also be reduced by adding dry lubricating oil.

[0026] The rotation center of the first rotating part and the rotation center of the second rotating part are both highly consistent with the optical center of the lens, and the anti-shake effect of the motor can be maximally exerted. In actual shooting, when the camera or other imaging equipment shakes, the assembly can quickly and accurately adjust the position of the lens, ensure that light always enters the lens along an ideal path, effectively reduce the blur phenomenon caused by shaking, and significantly improve the imaging quality, providing the user with a clear and sharp visual experience.

[0027] In addition, the wire or elastic piece suspension scheme adopted in the scheme is a major breakthrough over the traditional design. Through this unique suspension method, the second rotating part does not generate additional friction force when rotating along the Z axis. This feature makes the movement of the second rotating part more smooth and accurate during rotation, effectively reducing control errors. Whether shooting static objects or capturing dynamic moments, the stability and accuracy of the lens can be ensured, providing the user with an even better shooting experience.

[0039] The technical solutions in the present application will be described below in connection with the drawings. Embodiment 1

[0040] The embodiment provides a periscopic lens motor, which comprises a base 100, an upper cover 110, an automatic focusing module 200, an optical anti-shake assembly 300 and a prism 400. The optical anti-shake assembly 300 is arranged on the base 100 and is used for bearing the prism 400, and comprises a first rotating part 310, a second rotating part 320, a Y-axis power unit 330 and a Z-axis power unit 340. The two sides of the first rotating part 310 are provided with a cylinder 311. The first rotating part 310 can rotate around the Y axis relative to the base 100 with the cylinder 311 as the rotation center under the action of the Y-axis power unit 330. The second rotating part 320 is suspended on the first rotating part 310 through a wire 321. The second rotating part 320 can rotate around the Z axis relative to the first rotating part 310 under the action of the Z-axis power unit 340. The rotation center of the first rotating part 310 and the rotation center of the second rotating part 320 are consistent with the optical center of the prism 400. The base 100 is provided with a supporting groove 101 matched with the cylinder 311. The supporting groove 101 is in a V shape and is used for supporting the cylinder 311, so that the frictional resistance of the first rotating part 310 during rotation is smaller.

[0041] The two sides of the first rotating part 310 are provided with the cylinder 311, which provides support for the rotation of the first rotating part 310 and serves as the rotation center of the first rotating part 310. Through fine adjustment of the position of the cylinder 311, the rotation center of the first rotating part 310 can be accurately realized to be completely coincident with the optical center of the prism 400. As for the second rotating part 320, the second rotating part 320 is suspended and supported through the suspension scheme of the wire 321. The suspension scheme gives the second rotating part 320 relative independence in space. When the second rotating part 320 rotates along the Z axis, that is, when the second rotating part 320 rotates in the Rolling mode, the rotation center of the second rotating part 320 can also be very easily adjusted to be consistent with the optical center of the prism 400. The cylinder 311 can be made of metal. The friction of the first rotating part 310 during rotation can be reduced through polishing of the metal surface, and the friction can also be reduced through addition of dry lubricating oil.

[0042] The rotation center of the first rotating part 310 and the rotation center of the second rotating part 320 are highly consistent with the optical center of the prism 400, and can maximize the anti-shake effect of the motor. In actual shooting, when the camera or other imaging equipment shakes, the assembly can quickly and accurately adjust the position of the prism 400, ensure that the light always enters the prism 400 along the ideal path, effectively reduce the blur phenomenon caused by shaking, and significantly improve the imaging quality, so as to bring clear and sharp visual experience to the user.

[0043] In addition, the suspension scheme of the wire 321 adopted in this solution is a major breakthrough over traditional designs. Through this unique suspension method, the second rotating part 320 will not generate additional friction when rotating along the Z-axis. This feature makes the movement of the second rotating part 320 more smooth and accurate during rotation, effectively reducing control errors. Whether shooting static objects or capturing dynamic moments, it can ensure the stability and accuracy of the prism 400, providing users with a better shooting experience.

[0044] In this embodiment, the second rotating part 320 is suspended from the first rotating part 310 by four wires 321.

[0045] The suspension layout of the four wires 321 can provide uniform and stable support force for the second rotating part 320. During the rotation of the second rotating part 320 around the Z-axis, this uniform support force distribution can effectively avoid shaking or deviation caused by uneven force, ensuring high-precision execution of the rotating action. Compared with traditional suspension methods, this design greatly improves the rotation stability of the second rotating part 320, enabling the prism 400 to adjust the angle more smoothly during Rolling rotation, thereby further improving the clarity and stability of the image. By adjusting the positions of the four wires 321 so that their center lines coincide with the optical center position of the prism 400, the rotation center of the second rotating part 320 can be ensured to coincide with the optical center of the prism 400.

[0046] In this embodiment, the second rotating part 320 is provided with connecting pieces 323 on both sides, and the middle sections of the wires 321 are connected to the connecting pieces 323, and the both ends of the wires 321 are connected to the first rotating part 310.

[0047] The connecting pieces 323 provide a stable connection point between the wires 321 and the second rotating part 320. When the second rotating part 320 rotates around the Z-axis under the action of the Z-axis power unit 340, the connecting pieces 323 can make the force exerted by the wires 321 on the second rotating part 320 more evenly and reasonably distributed. The middle sections of the wires 321 are connected to the connecting pieces 323, and the both ends are connected to the first rotating part 310, forming a stable mechanical structure. During rotation, force can be evenly transmitted to the first rotating part 310 along the wires 321 through the connecting pieces 323, avoiding deformation or damage caused by excessive local force. This optimized force transmission and distribution mechanism not only helps to improve the rotation accuracy of the second rotating part 320, but also prolongs the service life of the wires 321 and the entire optical anti-shake assembly 300, ensuring that it always maintains good performance during long-term use. The presence of the connecting pieces 323 also makes the installation of the wires 321 more convenient and accurate.

[0048] In the embodiment, the second rotating part 320 is suspended on the first rotating part 310 by four wires 321, which are welded or glued with the embedded metals of the first rotating part 310 and the second rotating part 320.

[0049] The welding or gluing method can make the wires 321 and the embedded metals of the first rotating part 310 and the second rotating part 320 form a firm connection. During the welding process, the metal materials are fused together at high temperature to form a whole structure. This connection method has very high strength and stability and can withstand a large external force without loosening or falling off. The gluing method tightly combines the wires 321 and the embedded metals through the viscosity of the glue. The glue fills the small gap between them, not only increases the contact area, but also effectively prevents external factors from interfering with the connection part, ensuring that the connection between the wires 321 and the rotating part is still stable and reliable in various complex working environments, such as vibration, impact or large temperature changes. This provides a solid guarantee for the stable suspension of the second rotating part 320.

[0050] In the embodiment, the Y-axis power unit 330 includes a Y-axis coil 331 and a Y-axis magnet 332. The Y-axis coil 331 is arranged on the base 100, and the Y-axis magnet 332 is arranged on the first rotating part 310. The Z-axis power unit 340 includes a Z-axis coil 341 and a Z-axis magnet 342. The Z-axis coil 341 is arranged on the base 100, and the Z-axis magnet 342 is arranged on the second rotating part 320.

[0051] The Y-axis power unit 330 and the Z-axis power unit 340 use the combination of coils and magnets to achieve efficient conversion of electrical energy to mechanical energy. When an electric current passes through the Y-axis coil 331, a magnetic field is generated, which interacts with the magnetic field of the Y-axis magnet 332, thereby generating a Lorentz force to drive the first rotating part 310 to rotate around the Y-axis. Similarly, the interaction between the Z-axis coil 341 and the Z-axis magnet 342 can drive the second rotating part 320 to rotate around the Z-axis. This power transmission method based on electromagnetic induction principle has very high energy conversion efficiency, which can quickly and effectively convert electrical energy into mechanical energy required for rotational motion, so that the optical anti-shake assembly 300 can quickly respond to the shaking of the device and timely adjust the position of the prism 400 to ensure clear and stable imaging. Embodiment 2

[0052] Compared with embodiment 1, the difference of the embodiment is that the wires are replaced by elastic members 322. The second rotating part 320 is provided with connecting members 323 on both sides, the middle section of the elastic member 322 is connected to the connecting member 323, and the both ends of the elastic member 322 are connected to the first rotating part 310. The second rotating part 320 is suspended on the first rotating part 310 by four elastic members 322, and the elastic members 322 and the first rotating part 310 and the second rotating part 320 are riveted by rivets 324.

[0053] The elastic member 322 is specifically a spring sheet, which can increase the toughness during falling and improve the anti-falling capability. The riveting mode of the rivet column 324 provides a very stable connection between the elastic member 322 and the first rotating part 310 and the second rotating part 320. In the riveting process, after the rivet column 324 passes through the corresponding parts of the elastic member 322 and the rotating part, a firm combination is formed through riveting deformation. Even in the long-term use process, in the face of frequent vibration, impact and complex working environment, the riveting structure can still maintain a close connection state, ensuring that the elastic member 322 and the rotating part will not appear loose, fall off and other problems, thereby providing a reliable guarantee for the stable suspension of the second rotating part 320, greatly prolonging the service life of the optical anti-shake assembly 300.

[0054] Although the embodiments of the present application have been shown and described, it should be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
