[0001] The present application belongs to the field of communication technology, and specifically relates to an optical image stabilization motor, a camera module and an electronic device. Background Art

[0002] As users pursue the ultimate user experience, their performance requirements for electronic devices such as mobile phones and tablets are getting higher and higher. For example, in mobile phones, camera modules with optical image stabilization functions are becoming more and more common. Suspended wire optical image stabilization motors are a common type of optical image stabilization motor. They are widely used in camera modules because of their simple structure and good anti-shake effect.

[0003] In the existing technology, the suspension wire optical image stabilization motor can generally include a base, a frame, and a suspension wire connected between the base and the frame, and the two ends of the suspension wire are welded to the base and the frame respectively. The suspension wire can generally be used to suspend and support the frame, provide elastic support to the frame and limit the movement of the frame to achieve precise displacement of the frame, thereby achieving the anti-shake function.

[0004] However, since the suspension wire is prone to breakage during elastic deformation, especially at the welding connection between the suspension wire and the base or frame, the suspension wire and the pad are easily separated, which will affect the anti-shake effect of the optical anti-shake motor, thereby affecting the shooting effect and the user's shooting experience. Summary of the invention

[0027] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] The embodiment of the present application provides an optical image stabilization motor, which can be used in a camera module. Specifically, the camera module can also include a lens assembly, and the optical image stabilization motor can be connected to the lens assembly to achieve image stabilization of the lens assembly.

[0029] Reference Figure 1 , showing one of the structural schematic diagrams of the optical image stabilization motor described in the embodiment of the present application, referring to Figure 2, shows the second structural schematic diagram of the optical image stabilization motor described in the embodiment of the present application. Figure 2 As shown, the optical image stabilization motor may specifically include: a base 10; a frame 11, which may be used to support a lens assembly; and a plurality of suspension wires 12, which are spaced apart between the base 10 and the frame 11, one end of the suspension wire 12 being connected to the base 10, and the other end of the suspension wire 12 being connected to the frame 11, and the suspension wire 12 being made of a self-healing material.

[0030] In the embodiment of the present application, the suspension wire 12 of the optical image stabilization motor can be made of a self-healing material. In the case where the suspension wire 12 is damaged, the suspension wire 12 made of a self-healing material can identify the damage and perform self-repair, thereby avoiding the risk of the suspension wire 12 breaking and increasing the service life of the suspension wire 12. Thus, the impact of the suspension wire 12 breaking on the anti-shake effect of the optical image stabilization motor can be avoided, thereby improving the shooting effect of the camera module using the optical image stabilization motor and the user experience.

[0031] In practical applications, the base 10 can be used to support the suspension wire 12 and the frame 11, and the frame 11 can be used to carry the lens assembly in the camera module. Figure 1 The movement of the suspension wire 12 in the horizontal plane is perpendicular to the horizontal plane, so as to drive the lens assembly to adjust its position accordingly in the horizontal direction to achieve the anti-shake function.

[0032] like Figure 1 As shown, when the electronic device is in a stationary state, the suspension wire 12 is vertically connected between the base 10 and the frame 11. When the frame 11 moves relative to the base 10 to Figure 2 After the state shown, the suspension wire 12 will change position accordingly and deform into Figure 2 That is, in the process of achieving anti-shake, the suspension wire 12 may be in the tilted state shown. Figure 1 The status and Figure 2 The states shown are switched repeatedly, causing damage to the suspension wire 12 .

[0033] In the embodiment of the present application, since the suspension wire 12 is made of a self-healing material, when the suspension wire 12 is damaged, the suspension wire 12 made of the self-healing material can identify the damage and perform self-repair, thereby avoiding the risk of the suspension wire 12 breaking and increasing the service life of the suspension wire 12.

[0034] In practical applications, self-healing new materials are new materials that can self-repair after being damaged. This property mimics the self-healing ability of organisms after being damaged. The research and application of self-healing new materials are gradually changing the way materials are used and maintenance strategies, bringing innovative solutions to many fields. Its self-healing mechanism is: self-healing new materials usually achieve self-healing through built-in or external healing agents. When these materials suffer mechanical damage, they can release or activate healing agents to repair cracks or damage.

[0035] Specifically, the self-healing material may include: at least one of copper-coordinated diacetyl oxime amine and polyborosiloxane. The embodiment of the present application may not limit the specific type of the self-healing material.

[0036] In practical applications, in addition to being used to elastically support the frame 11, part of the suspension wire 12 is usually also used for electrical connection between the frame 11 and the base 10 to power the lens assembly on the frame 11. Therefore, correspondingly, the self-healing material can also include at least one of a conductive self-healing material and a non-conductive self-healing material to set the material of the suspension wire 12 as needed.

[0037] For example, a person skilled in the art may make the wires 12 that need to be conductive among the multiple wires 12 be made of conductive healing materials, and the other wires 12 that do not need to be conductive be made of non-conductive self-healing materials, so as to reduce the material cost of the wires 12. For another example, in order to reduce the types of wires 12 and facilitate material management, all wires 12 may be made of conductive self-healing materials or non-conductive self-healing materials. The present application embodiment does not specifically limit the material of the wires 12.

[0038] For example, the basic components of the conductive self-healing material are usually based on conductive polymers, such as poly 3,4-ethylenedioxythiophene (PEDOT), polypyrrole (PPy) and polyaniline (PANI). These polymers not only have good conductivity, but also exhibit excellent mechanical properties and stability. The non-conductive self-healing material may include polyborosiloxane, etc. The embodiment of the present application does not specifically limit the types of the conductive self-healing material and the non-conductive self-healing material.

[0039] like Figure 1 , Figure 2As shown, the end of the suspension wire 12 is also provided with an elastic connection part 121, and the suspension wire 12 is connected to the base 10 or the frame 11 through the elastic connection part 121. The elastic connection part 121 can be used to realize the elastic connection between the suspension wire 12 and the base 10 and the suspension wire 12 and the frame 11. When the suspension wire 12 is deformed or the position changes, the elastic connection part 121 can be deformed to absorb more stress, so as to avoid the suspension wire 12 from breaking at the connection with the base 10 or the frame 11.

[0040] In actual applications, when the suspension wire 12 is deformed or changes position, the place with the greatest stress appears at the connection between the suspension wire 12 and the base 10 and the frame 11, that is, the position where the suspension wire 12 is connected to the frame 11 or the base 10 is most likely to break. Figure 3 The status shown switches to Figure 4 When the status shown is Figure 4 As shown, the elastic connection portion 121 can absorb more stress through elastic deformation, thereby preventing the suspension wire 12 from breaking at the connection with the base 10 or the frame 11. Thus, the service life of the suspension wire 12 can be extended.

[0041] Optionally, the elastic connection part 121 and the suspension wire 12 are an integrally formed structure, so that the connection between the elastic connection part 121 and the suspension wire 12 is more reliable. That is, the elastic connection part 121 can be made of the same self-healing material as the suspension wire 12, and the elastic connection part 121 and the suspension wire 12 can be formed at one time by injection molding or other molding methods to improve the connection reliability between the two. Thus, the suspension wire 12 is not prone to breakage at the end.

[0042] Alternatively, the elastic connection part 121 and the suspension wire 12 are separate structures, that is, the suspension wire 12 and the elastic connection part 121 can be processed separately, and then the suspension wire 12 and the elastic connection part 121 are connected together, so that the structures of the suspension wire 12 and the elastic connection part 121 are relatively simple and easy to process.

[0043] In practical applications, when the suspension wire 12 and the elastic connection part 121 are separate structures, the elastic connection part 121 can be made of self-healing material or other materials that can be deformed, and the embodiment of the present application does not specifically limit the material of the elastic connection part 121. Moreover, the connection method between the suspension wire 12 and the elastic connection part 121 can be welding, bonding, etc., and the embodiment of the present application does not specifically limit the connection method between the suspension wire 12 and the elastic connection part 121.

[0044] like Figure 5As shown, when the shape of the frame 11 is rectangular, the number of the suspension wires 12 can be 4, and these 4 suspension wires 12 can be respectively set close to the top corners of the frame 11 to limit the position of the frame 11 from the top corner position of the frame 11, thereby optimizing the anti-shake effect of the frame 11.

[0045] like Figure 5 , Figure 6 As shown, the elastic connecting part 121 may specifically include: an elastic part 1211 and a plurality of fixed parts 1212 connected around the elastic part 1211; wherein the elastic part 1211 is connected to the end of the suspension wire 12, the elastic part 1211 may undergo elastic deformation to absorb more stress, and the fixed part 1212 is connected to the base 10 or the frame 11.

[0046] In a specific application, by providing a plurality of fixing portions 1212 surrounding the elastic portion 1211 around the elastic portion 1211, and connecting the plurality of fixing portions 1212 to the base 10 or the frame 11, the connection reliability between the fixing portions 1212 and the base 10 or the frame 11 can be greatly improved, further avoiding the possibility of the suspension wire 12 breaking at the end, and extending the service life of the suspension wire 12.

[0047] In the embodiment of the present application, the connection method between the fixing part 1212 and the frame 11 and the base 10 includes: at least one of a welding connection and an adhesive connection. The embodiment of the present application does not specifically limit the connection method between the fixing part 1212 and the base 10 or the frame 11.

[0048] In practical applications, when the suspension wire 12 needs to be conductive, the fixing portion 1212 and the frame 11 or the base 10 can be connected by welding or conductive adhesive bonding. When the suspension wire 12 does not need to be conductive, the fixing portion 1212 and the frame 11 or the base 10 can be connected by a common adhesive medium. The embodiment of the present application does not specifically limit the connection method between the fixing portion 1212 and the base 10 or the frame 11.

[0049] Optionally, the elastic portion 1211 at least partially protrudes toward the suspension wire 12 to further increase the elastic deformation of the elastic portion 1211 so that the elastic portion 1211 can absorb as much stress as possible, thereby avoiding breakage of the suspension wire 12 at the connection with the base 10 or the frame 11 to the greatest extent and extending the service life of the suspension wire 12.

[0050] For example, the protrusion of the elastic portion 1211 may be in the shape of an arc-shaped protrusion or a wing-shaped protrusion. The embodiment of the present application does not specifically limit the protrusion shape of the elastic portion 1211.

[0051] In summary, the optical image stabilization motor described in the embodiment of the present application can at least include the following advantages:

[0052] In the embodiment of the present application, the suspension wire of the optical image stabilization motor is made of a self-healing material. In the event that the suspension wire is damaged, the suspension wire made of the self-healing material can identify the damage and perform self-repair, thereby avoiding the risk of the suspension wire breaking and increasing the service life of the suspension wire. Thus, the impact of the suspension wire breaking on the anti-shake effect of the optical image stabilization motor can be avoided, thereby improving the shooting effect of the camera module using the optical image stabilization motor and the user experience.
