Description

Technical Field

[0001] This application belongs to the technical field of electronic devices, and particularly relates to a camera module and an electronic device. Background Art

[0002] Electronic devices achieve the shooting function by setting a camera module. However, due to the limited internal space of the electronic device, the shooting effect of the camera module is restricted.

[0003] In related technologies, to improve the shooting effect of electronic devices, some movable components are set on the camera module. When the user uses the electronic device to shoot videos or pictures, according to the shooting needs of the camera module, these movable components are moved to corresponding positions to improve the shooting effect of the camera module. When the camera module is not working, these movable components are moved to another position, thereby reducing the volume of the camera module. However, when the movable components are moving, the power is transmitted from the driving component to the movable component through the transmission component, and the power will be stuck during the transmission process, resulting in the movable component being unable to move accurately to the corresponding position, thereby affecting the shooting effect of the camera module. Summary of the Invention

[0004] This application aims to provide a camera module and an electronic device, at least solving one of the problems that the power will be stuck during the transmission process, resulting in the movable component being unable to move accurately to the corresponding position, thereby affecting the shooting effect of the camera module.

[0005] To solve the above technical problems, this application is implemented as follows:

[0006] In a first aspect, an embodiment of this application provides a camera module, including a circuit board, a lens assembly, movable vanes, a first decorative ring, a second decorative ring, a first coil, and a second coil; the lens assembly is arranged on the circuit board; a plurality of movable vanes surround the circumferential direction of the light incident side of the lens assembly; the first decorative ring covers the lens assembly and the movable vanes; the second decorative ring is arranged in the first decorative ring and is used to move relative to the first decorative ring in a direction perpendicular to the circuit board; the first coil is arranged on the circuit board; when the first coil is energized, the first coil drives the movable vanes to move radially away from the lens assembly; when the second coil is energized, the second coil drives the second decorative ring to move away from the circuit board.

[0007] In an embodiment of the present application, the camera module includes a first coil. The first coil is electrically connected to a circuit board, and the circuit board supplies power to the first coil. When the first coil is energized, the first coil drives the movable blade to move radially away from the lens assembly, achieving the control of the movable blade, so that the movable blade can change its position according to the working needs of the camera module, and improving the flexibility of the movable blade during the operation of the camera module. The electronic device supplies power to the first coil through the circuit board. After the first coil is energized, it can generate a magnetic field, and the magnetic field can drive the movable blade to move. There is no need for a mechanical structure to transmit power between the first coil and the movable blade, thereby reducing the probability of jamming during the power transmission process and improving the accuracy of the position of the movable blade during movement. Since the accuracy of the position of the movable blade during movement is improved, that is, the position where the movable blade is located is closer to the position specified by the theoretical design. When the movable blade moves to a position away from the lens assembly, the probability of the movable blade interfering with the telescopic movement of the lens assembly is reduced, making the telescopic movement of the lens assembly smoother, improving the accuracy of the zoom range and zoom ratio of the lens assembly, and thus improving the shooting effect of the camera module. When the movable blade moves to a position close to the lens assembly, the movable blade can fix the lens assembly more stably, improving the stability of the lens assembly, reducing the probability of damage to the lens assembly caused by external impact on the electronic device, and extending the service life of the camera module.

[0008] The camera module includes a second coil. When the second coil is energized, the second coil drives the second decorative ring to move away from the circuit board, achieving the control of the second decorative ring, so that the decorative ring can change its position according to the working needs of the camera module, and improving the flexibility of the second decorative ring during the operation of the camera module. The electronic device supplies power to the second coil. After the second coil is energized, it can generate a magnetic field, and the magnetic field can drive the second decorative ring to move. By driving the second decorative ring to move through the magnetic field generated by the second coil, there is no need for a mechanical structure to transmit power between the second coil and the second decorative ring, thereby reducing the probability of jamming during the power transmission process and improving the accuracy of the movement position of the second decorative ring. Since the accuracy of the movement position of the second decorative ring is improved, that is, the position where the second decorative ring is located is closer to the position specified by the theoretical design, the second decorative ring can reserve more sufficient space inside the camera module, enabling the lens assembly to have more sufficient space for telescopic movement, improving the accuracy of the zoom range and zoom ratio of the lens assembly, and thus improving the shooting effect of the camera module.

[0009] In a second aspect, an embodiment of the present application provides an electronic device, including the camera module according to any of the above technical solutions. Therefore, this electronic device has all the beneficial effects of the camera module according to any of the above technical solutions.

[0025] The following will be combined with Figures 1 to 7 Describe a camera module and an electronic device according to an embodiment of the present application.

[0026] As Figure 1 、 Figure 2 And Figure 3As shown, a camera module according to some embodiments of the present application includes a circuit board 100, a lens assembly 200, movable vanes 610, a first decorative ring 300, a second decorative ring 400, a first coil 700, and a second coil 510; the lens assembly 200 is disposed on the circuit board 100; a plurality of movable vanes 610 are disposed around the circumferential direction of the light incident side of the lens assembly 200; the first decorative ring 300 covers the lens assembly 200 and the movable vanes 610; the second decorative ring 400 is disposed within the first decorative ring 300 and is used to move relative to the first decorative ring 300 in a direction perpendicular to the circuit board 100 ( Figure 2 in the direction indicated by arrow F in the figure); the first coil 700 is disposed on the circuit board 100; when the first coil 700 is energized, the first coil 700 drives the movable vanes 610 in the radial direction ( Figure 2 in the direction indicated by arrow G in the figure), in a direction away from the lens assembly 200 ( Figure 2 in the direction indicated by arrow B in the figure); when the second coil 510 is energized, the second coil 510 drives the second decorative ring 400 in a direction away from the circuit board 100 ( Figure 2 in the direction indicated by arrow A in the figure).

[0027] In an embodiment of the present application, the camera module includes a first coil 700, the first coil 700 is electrically connected to the circuit board 100, and the circuit board 100 supplies power to the first coil 700; when the first coil 700 is energized, the first coil 700 drives the movable vanes 610 in the radial direction, in a direction away from the lens assembly 200, realizing the control of the movable vanes 610, so that the movable vanes 610 can change their positions according to the working needs of the camera module, improving the flexibility of the movable vanes 610 during the working process of the camera module. The electronic device supplies power to the first coil 700 through the circuit board 100. After the first coil 700 is energized, it can generate a magnetic field, and the magnetic field can drive the movable vanes 610 to move. There is no need for a mechanical structure to transmit power between the first coil 700 and the movable vanes 610, thereby reducing the probability of jamming during the power transmission process and improving the accuracy of the position of the movable vanes 610 when moving. Since the accuracy of the position of the movable vanes 610 when moving is improved, that is, the position where the movable vanes 610 are located is closer to the position specified by the theoretical design. When the movable vanes 610 move to a position away from the lens assembly 200, the probability of the movable vanes 610 interfering with the telescopic movement of the lens assembly 200 is reduced, making the telescopic movement of the lens assembly 200 smoother, improving the accuracy of the zoom range and zoom ratio of the lens assembly 200, and further improving the shooting effect of the camera module; when the movable vanes 610 move to a position close to the lens assembly 200, the movable vanes 610 can more stably fix the lens assembly 200, improving the stability of the lens assembly 200, reducing the probability of damage to the lens assembly 200 caused by external impact on the electronic device, and extending the service life of the camera module.

[0028] The camera module includes a circuit board 100 and a lens assembly 200. The lens assembly 200 is disposed on the circuit board 100, and the control of the lens assembly 200 is achieved through the circuit board 100, thereby realizing the shooting function of the camera module. The camera module further includes a first decorative ring 300 and a second decorative ring 400. The first decorative ring 300 covers the outside of the lens assembly 200, which realizes the protection of the internal components of the camera module, improves the stability of the internal components of the camera module during operation, and extends the service life of the internal components of the camera module. The second decorative ring 400 is disposed within the first decorative ring 300 and is capable of moving relative to the first decorative ring 300. The first decorative ring 300 provides support for the second decorative ring 400, improving the stability of the second decorative ring 400 during movement.

[0029] The camera module further includes a second coil 510. When the second coil 510 is energized, the second coil 510 drives the second decorative ring 400 to move away from the circuit board 100, realizing the control of the second decorative ring 400, so that the decorative ring can change its position according to the working needs of the camera module, improving the flexibility of the second decorative ring 400 during the operation of the camera module. The electronic device supplies power to the second coil 510. After the second coil 510 is energized, it can generate a magnetic field, and the magnetic field can drive the second decorative ring 400 to move; by driving the second decorative ring 400 to move through the magnetic field generated by the second coil 510, there is no need for a mechanical structure to transmit power between the second coil 510 and the second decorative ring 400, thereby reducing the probability of jamming during the power transmission process and improving the accuracy of the movement position of the second decorative ring 400. Since the accuracy of the movement position of the second decorative ring 400 is improved, that is, the position where the second decorative ring 400 is located is closer to the position specified by the theoretical design, the second decorative ring 400 can reserve more sufficient space for the inside of the camera module, enabling the lens assembly 200 to have more sufficient space for telescoping, improving the accuracy of the zoom range and zoom ratio of the lens assembly 200, and thus improving the shooting effect of the camera module.

[0030] By driving the second decorative ring 400 to move through the magnetic field generated by the second coil 510, the driving structure of the second decorative ring 400 is simplified, the volume of the driving structure of the second decorative ring 400 is reduced, and thus the occupation of the internal space of the camera module by the driving structure of the second decorative ring 400 is reduced, which is beneficial to the miniaturization of the camera module.

[0031] By driving the second decorative ring 400 to move through the magnetic field generated by the second coil 510, the response speed of the driving structure of the second decorative ring 400 is faster, the delay caused by controlling the driving structure of the second decorative ring 400 is reduced, and the user experience of the electronic device is improved.

[0032] The movement of the second decorative ring 400 is driven by the magnetic field generated by the second coil 510. There is less contact between the second coil 510 and the second decorative ring 400, and even no contact between them. Compared with driving the second decorative ring 400 through a mechanical structure, there is no mechanical wear during the process of driving the second decorative ring 400, which further improves the smoothness of driving the second decorative ring 400; and because there is no mechanical wear during the process of driving the second decorative ring 400, the service life of the driving structure of the second decorative ring 400 is extended, the reliability of the driving structure of the second decorative ring 400 is improved, and the quality of the camera module is further improved.

[0033] Specifically, the second coil 510 is electrically connected to the circuit board 100, and the circuit board 100 supplies power to the second coil 510. The second decorative ring 400 is disposed within the first decorative ring 300 and is capable of moving relative to the first decorative ring 300 between a first position ( Figure 2 the position of the second decorative ring 400 shown in ) and a second position ( Figure 3 the position of the second decorative ring 400 shown in ). The second position is a position farther from the circuit board 100 relative to the first position; the second coil 510 is electrically connected to the circuit board 100; wherein, when the second coil 510 is energized, the second coil 510 can drive the second decorative ring 400 to move from the first position to the second position.

[0034] The second decorative ring 400 can move relative to the first decorative ring 300 between the first position and the second position, and the second position is a position farther from the circuit board 100 relative to the first position. When the user takes pictures or videos through the camera module, the second decorative ring 400 can move to the second position, increasing the internal space of the camera module, enabling the lens assembly 200 to have a greater stroke, thereby improving the zoom range of the lens assembly 200 and the shooting effect of the camera module; when the camera module is not working, the second decorative ring 400 moves to the first position. When the second decorative ring 400 is in the first position, the protruding height of the second decorative ring 400 is lower, so that the overall volume of the camera module is smaller, which is beneficial to the thin and light of the electronic device.

[0035] Specifically, the movable blade 610 can move relative to the lens assembly 200 between a third position ( Figure 2 the position where the movable blade 610 is located shown in ) and a fourth position ( Figure 3It moves between the positions where the movable blade 610 is shown in [Figure X] (not shown). When the movable blade 610 is in the third position, the movable blade 610 presses on the side of the lens module 200 away from the circuit board 100. When the movable blade 610 is in the fourth position, the movable blade 610 is separated from the lens module 200. The first coil 700 is electrically connected to the circuit board 100. When the first coil 700 is energized, the first coil 700 can drive the movable blade 610 to move from the third position to the fourth position.

[0036] When the first coil 700 is energized, the first coil 700 can drive the movable blade 610 to move from the third position to the fourth position, realizing the control of the movable blade 610, so that the movable blade 610 can change its position according to the working needs of the camera module, improving the flexibility of the movable blade 610 during the working process of the camera module. The electronic device supplies power to the first coil 700 through the circuit board 100. After the first coil 700 is energized, it can generate a magnetic field, and the magnetic field can drive the movable blade 610 to move. The movable blade 610 is driven to move between the third position and the fourth position by the magnetic field generated by the first coil 700. There is no need for a mechanical structure to transmit power between the first coil 700 and the movable blade 610, thereby reducing the probability of jamming during the power transmission process and improving the accuracy of the position of the movable blade 610 when it moves to the third position and the fourth position. When the movable blade 610 moves to the fourth position, due to the higher accuracy of the position where the movable blade 610 is located, that is, the position where the movable blade 610 is located is closer to the fourth position specified by the theoretical design, the probability that the movable blade 610 still interferes with the telescoping of the lens module 200 is reduced, making the telescoping of the lens module 200 smoother, improving the accuracy of the zoom range and zoom ratio of the lens module 200, and thus improving the shooting effect of the camera module.

[0037] The movable blade 610 is driven to move between the third position and the fourth position by the magnetic field generated by the first coil 700, simplifying the driving structure of the movable blade 610, reducing the volume of the driving structure of the movable blade 610, and thus reducing the occupation of the internal space of the camera module by the driving structure of the movable blade 610, which is beneficial to the miniaturization of the camera module.

[0038] The movable blade 610 is driven to move between the third position and the fourth position by the magnetic field generated by the first coil 700, making the response speed of the driving structure of the movable blade 610 faster, reducing the delay caused by controlling the driving structure of the movable blade 610, and improving the user experience of the electronic device.

[0039] The magnetic field generated by the first coil 700 drives the movable blade 610 to move between the third position and the fourth position. There is less contact between the first coil 700 and the movable blade 610, and even no contact between the first coil 700 and the movable blade 610. Compared with driving the movable blade 610 through a mechanical structure, there is no mechanical wear during the process of driving the movable blade 610, which further improves the smoothness of driving the movable blade 610; and because there is no mechanical wear during the process of driving the movable blade 610, the reliability of the driving structure of the second decorative ring 400 is improved, the service life of the driving structure of the movable blade 610 is extended, and the quality of the camera module is further improved.

[0040] Further, the first coil 700 is wound along the vertical direction, and the magnetic induction lines of the magnetic field generated by the first coil 700 extend along the horizontal direction.

The camera module further includes a lens 800, and the lens 800 is arranged inside the second decorative ring 400 and on the side of the second decorative ring 400 away from the circuit board 100.

[0046] Further, the second coil 510 is wound along the horizontal direction, and the magnetic induction lines of the magnetic field generated by the second coil 510 extend along the vertical direction.

[0047] The second coil 510 is a longitudinal electromagnetic coil group.

[0048] The number of the second coils 510 is multiple, and the multiple second coils 510 are evenly distributed in the circumferential direction ( Figure 1 the direction indicated by the arrow E in the figure) of the second decorative ring 400. The number of the second coils 510 can be three, four or six.

[0049] Further, the first decorative ring 300 is a fixed decorative ring.

[0050] The electronic device further includes a housing, a battery cover, and a bracket. The battery cover is disposed on the housing, and the bracket is disposed on the housing. The bracket is used to support the circuit board 100.

[0051] The first decorative ring 300 is fixed to the battery cover or the first decorative ring 300 is fixed to the bracket.

[0052] According to some embodiments of the present application, as Figure 2 and Figure 3 shown, a top plate 330 is circumferentially provided on a side of the first decorative ring 300 away from the circuit board 100. The first decorative ring 300 is further provided with a first through hole 340. The top plate 330 is arranged around the first through hole 340. A bottom plate 320 is circumferentially provided on a side of the first decorative ring 300 close to the circuit board 100. The bottom plate 320 is arranged around the first through hole 340. The second decorative ring 400 includes a body 410 and a positioning portion 420. The positioning portion 420 and the body 410 are sequentially arranged in a direction away from the circuit board 100. The body 410 and the positioning portion 420 are disposed inside the first decorative ring 300. The diameter D4 of the positioning portion 420 is greater than the diameter D3 of the body 410. The diameter of the body 410 is less than the diameter of the first through hole 340. The diameter of the positioning portion 420 is greater than the diameter of the first through hole 340. The axis lines L3 of the body 410, the positioning portion 420, and the first through hole 340 coincide.

[0053] In this embodiment, a top plate 330 is circumferentially provided on a side of the first decorative ring 300 away from the circuit board 100. The first decorative ring 300 is further provided with a first through hole 340. The top plate 330 is arranged around the first through hole 340. A bottom plate 320 is circumferentially provided on a side of the first decorative ring 300 close to the circuit board 100. The bottom plate 320 is arranged around the first through hole 340. The top plate 330 and the bottom plate 320 cooperate to form an installation space inside the first decorative ring 300.

[0054] The second decorative ring 400 includes a body 410 and a positioning portion 420. The diameter D4 of the positioning portion 420 is greater than the diameter D3 of the body 410. The positioning portion 420 is located between the top plate 330 and the bottom plate 320. The diameter of the body 410 is less than the diameter of the first through hole 340. The diameter of the positioning portion 420 is greater than the diameter of the first through hole 340. The displacement of the positioning portion 420 is restricted by the top plate 330 and the bottom plate 320, thereby restricting the displacement of the second decorative ring 400 and improving the stability of the second decorative ring 400 during movement.

[0055] Further, the bottom plate 320 is a platform disposed at the bottom of the first decorative ring 300 and extending into the first decorative ring 300. The bottom plate 320 is arranged in a ring shape.

[0056] Specifically, the second coil 510 is disposed inside the first decorative ring 300.

[0057] According to some embodiments of the present application, as Figure 2 and Figure 3 shown, the top plate 330 is provided with a first mounting groove 310 extending towards the bottom plate 320. The camera module further includes a first elastic member 520. The first elastic member 520 is disposed in the first mounting groove 310. One end of the first elastic member 520 is connected to the top plate 330, and the other end of the first elastic member 520 is connected to the positioning portion 420. Wherein, when the second coil 510 is powered off, the first elastic member 520 is used to drive the second decorative ring 400 to move in the direction ( Figure 3 indicated by the arrow C in

[0058] ). In this embodiment, one end of the first elastic member 520 is connected to the top plate 330, and the other end of the first elastic member 520 is connected to the positioning portion 420, so that the movement of the second decorative ring 400 can drive the first elastic member 520 to deform, and the resilience generated after the first elastic member 520 deforms can also be applied to the second decorative ring 400. When the second coil 510 is powered off, the resilience generated by the first elastic member 520 can be transmitted to the second decorative ring 400, so that the first elastic member 520 can drive the second decorative ring 400 to move through the resilience, realizing the reset of the second decorative ring 400. The reset of the second decorative ring 400 is realized through the first elastic member 520, which simplifies the reset structure of the second decorative ring 400, reduces the probability of jamming of the second decorative ring 400 during the reset process, and improves the smoothness of the movement of the second decorative ring 400.

[0059] The first decorative ring 300 is provided with a first mounting groove 310 extending towards the bottom plate 320. The first elastic member 520 is disposed in the first mounting groove 310. The first elastic member 520 is guided and limited through the first mounting groove 310, so that the first elastic member 520 is compressed during the movement of the second decorative ring 400, and can stably release the resilience to the second decorative ring 400, avoiding the bending of the first elastic member 520 during the movement of the second decorative ring 400, and improving the stability of the first elastic member 520 during the movement of the second decorative ring 400.

[0060] Further, the first elastic member 520 can be a spring, or a rubber member or a resin member with certain elasticity.

[0083] Furthermore, the second sealing member 540 is a dust-proof foam. During the movement of the second decorative ring 400, the dust-proof foam can continuously participate in the sealing. The thickness of the dust-proof foam depends on the stroke of the second decorative ring 400. It is necessary to ensure that the preloading requirements are met when the second decorative ring 400 is in the first position and the second position.

[0086] Specifically, the second coil 510 is disposed below the first decorative ring 300 and the second decorative ring 400.

[0087] According to some embodiments of the present application, as Figure 2 and Figure 7As shown, the movable blade 610 is sequentially provided with a shielding portion 619, a connecting portion 618, and a first mounting portion 616 along the radial direction away from the lens module 200; the shielding portion 619 is parallel to the circuit board 100 and is disposed circumferentially on the light incident side of the lens module 200; the connecting portion 618 is perpendicular to the circuit board 100, one end is connected to the shielding portion 619, and the other end is connected to the first mounting portion 616; the first mounting portion 616 is parallel to the circuit board 100, and the first mounting portion 616 has a through groove 614 penetrating in a direction perpendicular to the circuit board 100.

[0088] In this embodiment, the shielding portion 619 is parallel to the circuit board 100 and is disposed circumferentially on the light incident side of the lens module 200. Thus, the protection of the lens module 200 is achieved through the shielding portion 619. While improving the stability of the lens module 200, the dustproof effect of the lens module 200 is also enhanced. The connecting portion 618 is perpendicular to the circuit board 100, one end is connected to the shielding portion 619, and the other end is connected to the first mounting portion 616, improving the smoothness during the movement of the movable blade 610.

The second elastic member 630 is used to drive the movable blade 610 to move in a direction close to the lens module 200, and the first coil 700 is used to drive the first mounting portion 616 to move into the second mounting groove 622.

[0090] In this embodiment, one end of the second elastic member 630 is connected to the groove seat 620, and the other end is connected to the movable blade 610, so that the movement of the movable blade 610 can drive the deformation of the second elastic member 630, and the resilience generated after the deformation of the second elastic member 630 can also be applied to the movable blade 610. The second elastic member 630 is in a compressed state, so that the second elastic member 630 has a certain resilience. When the first coil 700 is powered off, the resilience generated by the second elastic member 630 can be transmitted to the movable blade 610, and then the second elastic member 630 can drive the movement of the movable blade 610 through the resilience, realizing the reset of the movable blade 610. The reset of the movable blade 610 is realized through the second elastic member 630, which simplifies the reset structure of the movable blade 610, reduces the probability of jamming of the movable blade 610 during the reset process, and improves the smoothness of the movement of the movable blade 610. The second elastic member 630 is arranged in the second installation groove 622, and the second elastic member 630 is guided and limited through the second installation groove 622, so that the second elastic member 630 can be compressed or stretched during the movement of the movable blade 610 from the third position to the fourth position, and during the movement of the second elastic member 630 from the fourth position to the third position, the second elastic member 630 can stably release the resilience to the movable blade 610, avoiding bending of the second elastic member 630 during the movement of the movable blade 610, and improving the stability of the second elastic member 630 during the movement of the movable blade 610.

[0091] Further, the second elastic member 630 can be a spring, or a rubber member or a resin member with certain elasticity.

[0092] Further, when the movable blade 610 is in the fourth position, the second elastic member 630 is in a compressed state or a stretched state; when the first coil 700 is powered off, the second elastic member 630 can drive the movable blade 610 to move from the fourth position to the third position.

[0096] Furthermore, the groove seat 620 is fixed to the circuit board 100 or the bracket.

[0097] According to some embodiments of the present application, as Figure 2 and Figure 7 shown, a protrusion 612 is provided on the side of the first mounting portion 616 facing the groove seat 620. One end of the second elastic member 630 is connected to the protrusion 612, and the diameter D1 of the protrusion 612 is smaller than the diameter D2 of the notch of the second mounting groove 622.

[0098] In this embodiment, the diameter D1 of the protrusion 612 is smaller than the diameter D2 of the notch of the second mounting groove 622. At least a part of the protrusion 612 can be embedded in the second mounting groove 622 and is connected to the second elastic member 630. The protrusion 612 and the second mounting groove 622 cooperate to guide the movable blade 610, improving the stability of the movable blade 610 during movement.

[0099] According to some embodiments of the present application, as Figure 2 shown, the distance L1 between the first mounting portion 616 and the circuit board 100 is smaller than the distance L2 between the shielding portion 619 and the circuit board 100.

[0100] In this embodiment, the distance L1 between the first mounting portion 616 and the circuit board 100 is smaller than the distance L2 between the shielding portion 619 and the circuit board 100, making the movement of the movable blade 610 smoother.

[0101] According to some embodiments of the present application, as Figure 2 and Figure 6 shown, the bottom plate 320 is disposed on the side of the first mounting portion 616 facing away from the circuit board 100 and covers the through groove 614. The through groove 614, the bottom plate 320 and the circuit board 100 enclose a second mounting cavity 615, and at least a part of the first coil 700 is located in the second mounting cavity 615.

While realizing the installation of the first coil 700, the magnetic field generated by the first coil 700 can drive the movable blade 610 to move, thereby realizing the driving of the movable blade 610 by the first coil 700.

[0103] According to some embodiments of the present application, as Figure 2 and Figure 6 shown, the connecting portion 618 is disposed between the bottom plate 320 and the lens assembly 200.

[0104] In this embodiment, the connecting portion 618 is disposed between the bottom plate 320 and the lens assembly 200, and the bottom plate 320 and the lens assembly 200 cooperate to limit the connecting portion 618, so that the movable blade 610 moves more stably within a certain area.

[0105] According to some embodiments of the present application, as Figure 2 shown, at least a part of the first mounting portion 616 is the second magnetic member 650, or the first mounting portion 616 is provided with the second magnetic member 650; in the moving direction of the movable blade 610 ( Figure 2 the direction indicated by the arrow G in

[0106] ), the second magnetic member 650 is located on the side of the first coil 700 away from the lens assembly 200.

[0107] Specifically, the movable blade 610 is a metal part.

[0108] The movable blade 610 can be locally magnetized, so that a part of the movable blade 610 becomes the second magnetic member 650.

[0109] The movable blade 610 can also be magnetized as a whole, so that the whole movable blade 610 becomes the second magnetic member 650.

[0110] According to some embodiments of the present application, as Figure 1 , Figure 2 , Figure 3 and Figure 7 shown, the number of movable blades 610 is multiple, and the multiple movable blades 610 are arranged along the circumferential direction of the lens assembly 200 ( Figure 1 the direction indicated by the arrow E in

[0111] ). In this embodiment, the multiple movable blades 610 are arranged along the circumferential direction of the lens assembly 200, so that the pressure exerted by the movable blades 610 on the lens assembly 200 is more evenly distributed on the lens assembly 200, thereby improving the stability of the lens assembly 200.

[0112] Furthermore, the number of the second elastic members 630 is plural, and the plural second elastic members 630 are respectively connected to the plural movable vanes 610.

[0113] The number of the slot bases 620 is plural, and the plural slot bases 620 are arranged opposite to the plural movable vanes 610. When the electronic device is collided or impacted, the movable vanes 610 can effectively fix the lens module 200, reduce the probability of the lens module 200 being damaged due to the collision or impact of the electronic device, and improve the reliability of the electronic device.

[0114] The number of the first coils 700 is also plural, and the plural first coils 700 are respectively opposite to the plural movable vanes 610. The number of the first coils 700 is three, four or six, and the number of the slot bases 620, the number of the first coils 700 and the number of the second elastic members 630 are the same.

[0115] When the first coils 700 are electrified, the plural movable vanes 610 move away from the lens module 200 simultaneously, and the plural movable vanes 610 are unfolded.

[0116] When the first coils 700 are powered off, the plural elastic members respectively drive the plural movable vanes 610 to close.

[0117] The electronic device according to some embodiments of the present application includes the camera module as described in any one of the above embodiments, so that the electronic device has all the beneficial effects of the camera module as described in any one of the above embodiments.

[0118] Furthermore, the electronic device includes a mobile phone, a tablet computer, an e-book, a smart wearable device or a notebook computer.

[0119] Furthermore, when the user uses the electronic device to take pictures through the camera module, when the camera module is started, the circuit board 100 synchronously triggers the second coil 510 to push the second decorative ring 400 to extend out and the first coil 700 to push the movable vanes 610 to unfold.

[0120] When the user stops using the electronic device to take pictures through the camera module, when the camera module is turned off, the second coil 510 and the first coil 700 are powered off, the first elastic member 520 drives the second decorative ring 400 to retract, and the second elastic member 630 drives the movable vanes 610 to close.

[0121] Since the camera module drives the second decorative ring 400 through the second coil 510 and drives the movable vanes 610 through the second coil 510, the volume of the camera module can be reduced, so that the occupation of the internal space of the electronic device by the camera module can also be reduced, and further the thickness of the electronic device can be reduced.

[0122] Specifically, as Figure 2 and Figure 3As shown, when the camera module is activated: the lens assembly 200 extends, and the circuit board 100 synchronously sends a signal to energize the second coil 510 and the first coil 700. Among them, when the second coil 510 is energized, it generates a magnetic force to push the second decorative ring 400 to move in the direction of the arrow A shown in Figure 2 against the resistance of the first elastic member 520 and extend out of the first decorative ring 300; the first coil 700 is synchronously energized to generate an electromagnetic force to push the movable vane 610 to move in the direction of the arrow B shown in Figure 2 against the resistance of the second elastic member 630, and the multiple movable vanes 610 are unfolded. This process ensures that during the telescopic process of the camera module, the second decorative ring 400 and the movable vanes 610 do not interfere with the lens assembly 200.

[0123] When the camera module is deactivated: the lens assembly 200 retracts, the circuit board 100 synchronously turns off the signal, the second coil 510 and the first coil 700 are de-energized, and the second decorative ring 400 and the movable vanes 610 lose the repulsive force of the electromagnetic coil. Under the extrusion force of the first elastic member 520 and the second elastic member 630, the second decorative ring 400 moves in the direction of the arrow C shown in Figure 3 , and the movable vanes 610 move in the direction of the arrow D shown in Figure 3 . The second decorative ring 400 and the movable vanes 610 are pulled back along their respective movement trajectories. This process reduces the overall thickness of the electronic device and realizes the protection of the camera module.

[0124] During the entire movement process, the second sealing member 540 is always involved in sealing. However, it should be noted that the thickness of the second sealing member 540 is determined according to the stroke of the movable second decorative ring 400, and it is necessary to ensure that the preloading requirements are met before and after the movement. At the same time, a high-rebound material should be selected to avoid the deterioration of the resilience after multiple extrusions and the inability to seal.
