Description

Technical Field

[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 a more refined user experience, they are placing increasingly higher demands on the performance of electronic devices such as mobile phones and tablets. For example, camera modules with optical image stabilization (OIS) are becoming increasingly common in mobile phones. Suspended-wire OIS motors, a common type of OIS motor, are widely used in camera modules due to their simple structure and excellent OIS performance.

[0003] In existing technology, a suspension-wire optical image stabilization motor typically consists of a base, a frame, and a suspension wire connected between the base and frame. The ends of the suspension wire are welded to the base and frame, respectively. The suspension wire is typically used to suspend and support the frame, providing elastic support and limiting its movement, achieving precise displacement and thus achieving the image stabilization function.

[0004] However, since the suspension wires are prone to breakage during elastic deformation, especially at the soldered joints between the suspension wires and the base or frame, separation from the soldering pads is very likely to occur. This can affect the optical image stabilization motor's stabilization effect, thereby affecting the shooting quality and the user's shooting experience. Summary of the Invention

[0005] The present application aims to provide an optical image stabilization motor, a camera module, and an electronic device to solve the problem that existing optical image stabilization motors are prone to failure.

[0027] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0028] The present invention 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 , shows one of the structural diagrams of the optical image stabilization motor according to an embodiment of the present application, referring to Figure 2, shows the structure schematic diagram two of the optical anti-shake motor. As shown in the figure and Figure 2 The optical anti-shake motor can specifically include: a base 10; a frame 11, which can be used to carry a lens assembly; and a plurality of suspension wires 12, which are arranged at intervals between the base 10 and the frame 11, one end of each of the suspension wires 12 being connected to the base 10 and the other end being connected to the frame 11, and the suspension wires 12 being made of a self-healing material.

[0030] In the embodiment, the suspension wires 12 of the optical anti-shake motor are made of a self-healing material. In the case of damage to the suspension wires 12, the suspension wires 12 made of a self-healing material can identify the damage and repair themselves, avoiding the risk of breakage of the suspension wires 12 and increasing the service life of the suspension wires 12. Thus, the influence of breakage of the suspension wires 12 on the anti-shake effect of the optical anti-shake motor can be avoided, and the shooting effect of the camera module to which the optical anti-shake motor is applied and the user's experience can be improved.

[0031] In actual application, the base 10 can be used to support the suspension wires 12 and the frame 11, and the frame 11 can be used to carry the lens assembly in the camera module. The frame 11 can move relative to the base 10 in the horizontal direction (a horizontal plane perpendicular to the suspension wires 12 in the base 10) to drive the lens assembly to make corresponding position adjustment in the horizontal direction, thereby realizing the anti-shake function. Figure 1

[0032] As shown in the figure and Figure 1 In the case that the electronic device is in a stationary state, the suspension wires 12 are vertically connected between the base 10 and the frame 11. After the frame 11 moves relative to the base 10 to the state shown in the figure and Figure 2 The suspension wires 12 will change position accordingly and be deformed into the inclined state shown in the figure and Figure 2 That is, in the process of realizing anti-shake, the suspension wires 12 can repeatedly switch between the state shown in the figure and Figure 1 and the state shown in the figure and Figure 2 This can cause damage to the suspension wires 12.

[0033] In the embodiment, the suspension wires 12 are made of a self-healing material. In the case of damage to the suspension wires 12, the suspension wires 12 made of a self-healing material can identify the damage and repair themselves, avoiding the risk of breakage of the suspension wires 12 and increasing the service life of the suspension wires 12.

[0034] ​In practical applications, self-healing materials are novel materials capable of self-repair after damage, a property that mimics the self-healing ability of organisms. The research and application of self-healing materials are gradually changing how materials are used and maintained, bringing innovative solutions to a wide range of fields. Their self-healing mechanism is as follows: Self-healing materials typically achieve self-repair through internal or external healing agents. When mechanically damaged, these materials can release or activate these healing agents, repairing cracks or damage.

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

[0036] In practical applications, in addition to elastically supporting the frame 11, the suspension wires 12 are also typically used for electrical connection between the frame 11 and the base 10 to power the lens assembly on the frame 11. Accordingly, the self-healing material may further include at least one of a conductive self-healing material and a non-conductive self-healing material, so that the material of the suspension wires 12 can be adjusted as needed.

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

[0038] For example, the basic components of the conductive self-healing material are generally based on conductive polymers such as poly 3,4-ethylenedioxythiophene (PEDOT), polypyrrole (PPy) and polyaniline (PANI). These polymers not only have good electrical conductivity, but also exhibit excellent mechanical properties and stability. The non-conductive self-healing material may include polyborosiloxane and the like. 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 further provided with an elastic connection portion 121, and the suspension wire 12 is connected to the base 10 or the frame 11 via the elastic connection portion 121. The elastic connection portion 121 can be used to achieve an elastic connection between the suspension wire 12 and the base 10, and between the suspension wire 12 and the frame 11. When the suspension wire 12 is deformed or its position changes, the elastic connection portion 121 can deform to absorb more stress, thereby preventing the suspension wire 12 from breaking at the connection with the base 10 or the frame 11.

[0040] In actual application, when the suspension wire 12 is deformed or changes position, the maximum stress occurs at the connection between the suspension wire 12 and the base 10 and the frame 11, that is, the connection between the suspension wire 12 and 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 portion 121 and the suspension wire 12 are integrally formed to provide a more reliable connection between them. Specifically, the elastic connection portion 121 can be made of the same self-healing material as the suspension wire 12, and the elastic connection portion 121 and the suspension wire 12 can be molded in one piece, such as by injection molding, to improve the reliability of the connection between them. This makes it less likely that the suspension wire 12 will break at its end.

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

[0043] In actual applications, when the suspension wire 12 and the elastic connection portion 121 are separate structures, the elastic connection portion 121 can be made of a self-healing material or other deformable material. The embodiment of the present application does not specifically limit the material of the elastic connection portion 121. Moreover, the connection between the suspension wire 12 and the elastic connection portion 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 portion 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 can 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 can 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 to the base 10 or the frame 11 through these plurality of fixing portions 1212, the connection reliability between the fixing portion 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 welding connection and 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, if the suspension wire 12 needs to be conductive, the fixing portion 1212 can be connected to the frame 11 or base 10 by welding or bonding with a conductive adhesive. If the suspension wire 12 does not need to be conductive, the fixing portion 1212 can be connected to the frame 11 or base 10 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 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 to the greatest extent the breakage of the suspension wire 12 at the connection with the base 10 or the frame 11 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 embodiments of the present application can at least include the following advantages:

[0052] In an embodiment of the present application, the suspension wires of the optical image stabilization motor are made of a self-healing material. If the wires are damaged, they can detect the damage and repair themselves, preventing the risk of wire breakage and increasing their service life. This prevents the impact of wire breakage on the optical image stabilization motor's image stabilization effect, improving the shooting quality and user experience of camera modules equipped with these optical image stabilization motors.
