[0030] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0032] The embodiments of the present application are described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0033] refer to Figure 1 , some camera modules disclosed in the related art include components such as a base 02 and a suspension wire 01. The base 02 is provided with a through hole, one end of the suspension wire 01 is inserted into the through hole, and one end of the suspension wire 01 is fixed to the base 02 by welding. In the initial state, the suspension wire 01 is in a vertical state, that is, the suspension wire 01 forms an angle of 90° with the upper surface of the base 02; after the anti-shake displacement, the suspension wire 01 is in an inclined state, so that the suspension wire 01 forms an acute angle with the upper surface of the base 02, such as an angle of 85°.

[0034] However, since one end of the suspension wire 01 is welded and fixed to the base 02, when the suspension wire 01 is tilted, the stress at the weld is concentrated, making the weld prone to breakage. In addition, during the anti-shake process, since one end of the suspension wire 01 is welded and fixed to the base 02, the suspension wire 01 is prone to bending and stress concentration when subjected to force. Over time, it is easy to cause fatigue or overload fracture of the suspension wire 01. Therefore, when the weld between the suspension wire 01 and the base 02 or the suspension wire 01 breaks, the camera anti-shake will fail, seriously affecting the camera effect and user experience.

[0035] refer to Figures 2 to 12 , the embodiment of the present application discloses a camera module, which can be applied to electronic devices to realize an anti-shake function. The disclosed camera module includes a lens (not shown in the figure), a housing 10, a base 20, a carrier 30 and a plurality of suspension wires 50. Of course, in addition to the above-mentioned components, the camera module may also include other components, such as a spring 40, a fixed frame, a focus power coil, a magnet group, an anti-shake power coil, etc., which are arranged on the carrier 30; wherein the spring 40 may include an upper spring leaf and a lower spring leaf.

[0036] The base 20 is disposed at one end of the housing 10, and the base 20 and the housing 10 form a chamber, the carrier 30 is disposed in the chamber, and connected to the base 20 through a plurality of suspension wires 50. Of course, the suspension wires 50 can also play the role of electrical connection to achieve power transmission.

[0037] In some embodiments, the fixed frame can be arranged in the chamber and serve as a basic installation component; the supporting member 30 is used to support the lens, which can be suspended in the space surrounded by the fixed frame through the upper spring leaf and the lower spring leaf, and the magnet group is clamped on the inner side of the fixed frame; in addition, one end of each suspension wire 50 is connected to the base 20, and the other end of each suspension wire 50 (that is, the end away from the first connecting structure) is fixedly connected to the spring sheet 40, so that the fixed frame and the upper spring leaf, the lower spring leaf, the supporting member 30, the lens, the magnet group and other components can all be suspended above the base 20 by relying on the suspension wire 50.

[0038] When the focus power coil is energized, under the action of the focus power coil, the carrier 30 and the lens it carries can move along the axial direction of the lens to achieve focus; when the anti-shake power coil is energized, the force generated by the anti-shake power coil can be transmitted to the carrier 30 through the suspension wire 50, so that the carrier 30 and the lens it carries can move for anti-shake. It should be noted here that the connection relationship between the components involved in the focus and anti-shake of the lens and the specific principles can refer to the existing technology and will not be elaborated here.

[0039] In order to effectively alleviate the breakage of the connection between the suspension wire 50 and the base 20 or the suspension wire 50 itself, in the embodiment of the present application, one end of the suspension wire 50 is movably connected to the base 20, so that during the anti-shake adjustment process, one end of the suspension wire 50 can move relative to the base 20, so as to alleviate the stress concentration problem at the connection between the suspension wire 50 and the base 20 and on the suspension wire 50 itself.

[0040] Specifically, one end of each suspension wire 50 may be provided with a first connection structure, and correspondingly, the base 20 may be provided with a plurality of second connection structures, and each second connection structure is movably connected to a corresponding first connection structure. Based on this, during the anti-shake adjustment process, the first connection structure at one end of each suspension wire 50 may be made to move relative to the corresponding second connection structure to alleviate the problem of stress concentration.

[0041] Based on the above settings, the embodiment of the present application can achieve an active connection between the suspension wire 50 and the base 20 through the cooperation of the first connecting structure and the second connecting structure, so that one end of the suspension wire 50 can move freely relative to the base 20. In this way, during the operation of the camera module, the stress at the connection between the suspension wire 50 and the base 20 and the stress borne by the suspension wire 50 itself can be reduced through the relative movement of the suspension wire 50 and the base 20, thereby effectively alleviating the problem of breakage at the connection between the suspension wire 50 and the base 20 or breakage of the suspension wire 50 itself, thereby extending the service life of the suspension wire 50, ensuring the service life of the entire camera module, and effectively preventing the connection between the suspension wire 50 and the base 20 or the suspension wire 50 itself from breaking, resulting in failure of camera anti-shake, thereby ensuring the camera effect and user experience.

[0042] refer to Figure 3 In some embodiments, the first connection structure may be provided with an arc-shaped convex surface 511, wherein the arc-shaped convex surface 511 may be a spherical convex surface, an ellipsoidal convex surface, a cylindrical convex surface, etc. Of course, it may also be in other forms, which are not specifically limited here.

[0043] Accordingly, if Figure 4 As shown, the second connection structure may be provided with an arc-shaped concave surface 211, wherein the arc-shaped concave surface 211 may be a spherical concave surface, an ellipsoidal concave surface, a cylindrical concave surface, etc. Of course, it may also be in other forms, which are not specifically limited here.

[0044] When mating, the arcuate concave surface 211 is wrapped around the outer side of the arcuate convex surface 511, and the arcuate convex surface 511 is movably connected to the arcuate concave surface 211. Based on this kind of mating, the first connection structure and the second connection structure can be freely moved, so as to adaptively adjust the angle between the suspension wire 50 and the base 20, so as to alleviate the problem of the connection between the suspension wire 50 and the base 20 and the suspension wire 50 itself being subjected to greater stress.

[0045] It should be noted here that the above-mentioned relative movement forms may include: relative rotation around a first axis, the first axis is not parallel to the suspension wire 50; relative rotation around a second axis, the second axis is parallel to the suspension wire 50; relative movement along the extension direction of the suspension wire 50; relative movement along a first direction, the first direction is not parallel to the extension direction of the suspension wire 50. Of course, the relative movement forms include not only the above-mentioned multiple single movement forms, but also a combination of at least two movement forms, as long as the suspension wire 50 and the base 20 can be relatively moved to unload the stress, and the specific relative movement forms are not limited.

[0046] To form the arc-shaped concave surface 211, the side of the base 20 facing the housing 10 may be provided with a plurality of grooves 21, such as Figure 4 As shown, the groove 21 can be used as the second connection structure, and the inner wall surface of each groove 21 is an arc-shaped concave surface 211. Considering that the arc-shaped concave surface 211 has various forms, the groove 21 can also have various forms, including: the groove 21 can be a spherical groove, an ellipsoidal groove, a cylindrical groove, etc. Of course, it can also be a groove of other irregular shapes, such as a pear-shaped groove, etc. The shape of the groove 21 is not specifically limited here.

[0047] Each suspension wire 50 may be provided with a terminal 51 at one end. Figure 3 As shown, the end 51 can be used as the first connection structure, and the outer surface of the end 51 is the arc-shaped convex surface 511. Considering that the arc-shaped convex surface 511 has various forms, the end 51 can also have various forms, including: the end 51 can be a spherical end, an ellipsoidal end, a cylindrical end, etc., and of course, it can also be a groove of other irregular shapes, such as a pear-shaped end, etc. The shape of the end 51 is not specifically limited here.

[0048] When mating, the end head 51 is movably connected to the groove 21, that is, the end head 51 and the groove 21 are combined by nested riveting. In this way, the free movement between the suspension wire 50 and the base 20 can be guaranteed through the movable cooperation between the end head 51 and the groove 21, thereby effectively alleviating the problem of stress concentration at the connection between the suspension wire 50 and the base 20 and the suspension wire 50 itself, and further alleviating the occurrence of breakage at the connection or the suspension wire 50 itself.

[0049] To prevent the suspension wire 50 from being separated from the base 20, in the embodiment of the present application, in a plane perpendicular to the axis direction of the lens, the projection area of ​​the notch of the groove 21 is smaller than the projection area of ​​the end 51. Based on this arrangement, the edge of the notch of the groove 21 can limit the end 51, so as to prevent the end 51 from being separated from the groove 21 when the suspension wire 50 is subjected to traction, thereby causing the anti-shake failure.

[0050] It should be noted that, considering the installation problem of the end head 51 and the groove 21, the projection area of ​​the notch can be slightly smaller than the projection area of ​​the end head 51 to avoid the situation where the end head 51 cannot be assembled. In this case, the groove 21 can be heated up or the end head 51 can be cooled down for installation, that is, the principle of thermal expansion and contraction can be used to install the end head 51 into the groove 21.

[0051] Of course, a hole may be opened at the bottom of the groove 21 , with the hole diameter being slightly larger than the above-mentioned projection area of ​​the end head 51 , so that the end head 51 can be installed in the groove 21 .

[0052] In a more specific embodiment, the end 51 can be spherical, the groove 21 can be a spherical groove, and at least part of the end is located in the spherical groove. In this way, the free and smooth rotation between the suspension wire 50 and the base 20 can be ensured, and the problem of the spherical end detaching from the spherical groove can be effectively alleviated.

[0053] In the embodiment of the present application, the first connection structure is rotatably connected to the corresponding second connection structure so that the two can rotate relative to each other, so that during the anti-shake process, the suspension wire 50 can be rotated relative to the base 20, which can help alleviate the problem of the suspension wire 50 and the base 20 being broken or the suspension wire 50 itself being broken, thereby extending the service life of the suspension wire 50 and the service life of the entire camera module. It should be noted here that the above-mentioned rotation can be achieved through a ball joint connection or an axis connection. Of course, other methods can also be used, which are not specifically limited here.

[0054] Considering that the suspension wire 50 can be made of a material with relatively poor rigidity and ductility, such as metal, its deformation in its own length direction is relatively small. When the suspension wire 50 deviates from the base 20 at a large angle during the anti-shake process, it is easy for the deformation of the suspension wire 50 to be unable to adapt to the deviation angle, resulting in the deformation of the suspension wire 50 being unable to offset the pulling force on the suspension wire 50 during the anti-shake process, thereby causing the suspension wire 50 to break itself.

[0055] Based on the above situation, in the extension direction of the suspension wire 50, there is a floating gap between the first connecting structure and the corresponding second connecting structure, so that the two can move relative to each other in the extension direction of the suspension wire 50. In this way, during the anti-shake process, the pulling force on the suspension wire 50 can be reduced by the relative movement between the first connecting structure and the second connecting structure, and the stress at the connection between the suspension wire 50 and the base 20 can also be reduced, thereby effectively reducing the risk of breakage of the suspension wire 50 or the breakage of the connection between the suspension wire 50 and the base 20.

[0056] To achieve relative movement, a certain gap may be provided between the arcuate concave surface 211 and the arcuate convex surface 511 in the extension direction of the suspension wire 50, so that the arcuate convex surface 511 can move in the arcuate concave surface 211 along the extension direction of the suspension wire 50 to achieve fine adjustment. Of course, it is not limited to the extension direction of the suspension wire 50, but may also be a direction that forms a certain angle with the extension direction of the suspension wire 50.

[0057] Based on the above arrangement, the first connecting structure and the second connecting structure in the embodiment of the present application can both rotate relative to each other and move relative to each other in the extension direction of the suspension wire 50. Moreover, during the anti-shake process, the suspension wire 50 is equivalent to a lever, and the arcuate concave surface 211 is equivalent to a fulcrum. The arcuate convex surface 511 of the suspension wire 50 can both rotate freely and slide freely within the arcuate concave surface 211, thereby reducing or even eliminating the force acting on the suspension wire 50 in the length direction, avoiding the transmission of tensile force and stress caused by the fixed connection method, greatly reducing the risk of breakage of the suspension wire 50 or breakage of the connection between the suspension wire 50 and the base 20 during the anti-shake process, and ensuring the service life of the suspension wire 50 and the entire camera module.

[0058] Of course, the suspension wire 50 can be appropriately lengthened to alleviate the problem of the suspension wire 50 being subjected to greater stress during the anti-shake process. The length of the suspension wire 50 can be calculated based on the maximum displacement of the camera module during the anti-shake process and the Pythagorean theorem.

[0059] In other embodiments, the material of the suspension wire 50 may also be a metal elastic material. In this way, during the anti-shake process, the breakage can be alleviated by the movement of the suspension wire 50 relative to the base 20, and the breakage can be alleviated by the deformation of the suspension wire 50 itself, thereby ensuring the service life of the suspension wire 50 and even the entire camera module.

[0060] Exemplarily, the suspension wire 50 may be a metal spring suspension wire made of a metal elastic material, and of course, may also be in other forms.

[0061] refer to Fig.10 To ensure stable suspension, the camera module may include four suspension wires 50. Accordingly, the four corners of the base 20 are provided with second connection structures, and the four suspension wires 50 are respectively movably connected to the second connection structures at the four corners of the base 20 through the first connection structures at one end of each of the four suspension wires 50. Based on this arrangement, the four suspension wires 50 can work together to ensure the stable suspension of the components inside the housing 10 and prevent random shaking.

[0062] The embodiment of the present application also discloses an electronic device, and the disclosed electronic device includes the above-mentioned camera module. The electronic device may include a mobile phone, a tablet computer, a smart wearable device, etc., and of course it may also be other devices, which are not specifically limited here.

[0063] To sum up, compared with the method of welding and fixing the suspension wire 50 and the base 20, the embodiment of the present application adopts a movable connection between the first connecting structure and the second connecting structure, which can not only solve the electrical connection problem, but also allow the suspension wire 50 to move freely relative to the base 20, thereby reducing the stress on the suspension wire 50 and the connection between the suspension wire 50 and the base 20, thereby extending the service life of the camera module.

[0064] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
