[0002] At present, the thickness of mobile devices is getting thinner and thinner. When the camera is integrated with other devices (such as mobile phones and tablets), the size of the camera needs to be as small as possible to fit in thinner mobile devices. The autofocus function of the lens is generally realized by the voice coil motor. The voice coil motor includes a mover part and a stator part. The mover part is fixed with the lens, and the mover part can move relative to the stator part in the direction of the optical axis. Due to the size of the camera, the internal space of the voice coil motor is limited, which puts forward high requirements for the miniaturization design of the internal drive components.

[0003] The existing sliding shaft voice coil motor has a stator part of a coil and a mover part of a magnet. In order to adapt to more demanding application scenarios, such as effectively improving the imaging quality of the camera module in different shooting environments, a variable aperture device is added to the front of the lens to adjust the amount of light entering the lens. This not only makes the assembly of the voice coil motor more and more difficult, but also makes the mover part heavier and the voice coil motor driving force insufficient. There is also the problem of unstable electrical connection between the variable aperture device and the lens drive motor.

[0004] Therefore, there is a problem of poor performance of the lens motor in the prior art. Utility Model Content

The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0030] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0031] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0032] In order to solve the problem of poor performance of lens motors in the prior art, the present application provides a lens driving device, a camera module and an electronic device.

[0033] Furthermore, the electronic device in the present application is generally a mobile terminal such as a mobile phone or a laptop computer having a camera module. The camera module in the present application has the following lens driving device.

[0034] like Figures 1 to 7As shown, the lens driving device in the present application includes a base assembly 10, a lens support body 20, an aperture adjustment part 200, a driving assembly, an FPC board 50 and a metal connector 80. The base assembly 10 has a containing space; at least a part of the lens support body 20 is movably arranged in the containing space; the aperture adjustment part 200 is arranged on the top of the lens support body 20 and can move with the lens support body 20; at least a part of the driving assembly is arranged on the lens support body 20, at least another part of the driving assembly is arranged on the base assembly 10 and drives the lens support body 20 to move relative to the base assembly 10; at least a part of the FPC board 50 is arranged on the lens support body 20 and is electrically connected to the part of the driving assembly located on the lens support body 20, and at least another part of the FPC board 50 is arranged on the base assembly 10; the metal connector 80 is arranged on the lens support body 20, and the metal connector 80 is electrically connected to the aperture adjustment part 200 and the FPC board 50 respectively.

[0035] When the lens driving device in the present application is used, the metal connector 80 is provided, so that the electrical connection between the aperture adjustment part 200 and the FPC board 50 can be achieved through the metal connector 80, thereby effectively ensuring the stable electrical connection of the aperture adjustment part 200. Therefore, compared with the traditional lens motor, the lens driving device in the present application has a more stable electrical connection of the aperture adjustment part 200. Therefore, the lens driving device in the present application effectively solves the problem of poor performance of the lens motor in the prior art.

[0036] Furthermore, it should be noted that in the present application, the metal connector 80 is electrically connected to a portion of the FPC board 50 disposed on the lens support body 20 , thereby achieving electrical connection with the FPC board 50 .

[0037] Optionally, at least a portion of the metal connector 80 is embedded in the lens support 20, and both ends of the metal connector 80 are respectively exposed outside the lens support 20 and electrically connected to the aperture adjustment part 200. This arrangement can effectively prevent the metal connector 80 from falling off the lens support 20, and can reduce the internal space of the lens driving device occupied by the metal connector 80.

[0038] Preferably, the two ends of the metal connector 80 are arranged along a diagonal line of the lens support 20. In addition, the aperture adjustment part 200 is respectively provided with at least two connection end pins at the two ends corresponding to the metal connector 80, and the connection end pins are welded to the two ends of the metal connector 80. Of course, according to the actual use situation, the position of the connection end pin of the aperture adjustment part 200 and the position of the two ends of the corresponding metal connector 80 can be adjusted, as long as the stability of the connection between the connection end pin and the metal connector 80 is guaranteed.

[0039] Optionally, the driving assembly includes a plurality of driving coils 30 and a plurality of driving magnets 40, the plurality of driving coils 30 are arranged on the lens support 20 and electrically connected to the FPC board 50, and the plurality of driving magnets 40 are arranged on the base assembly 10. In a specific embodiment of the present application, there are two driving coils 30, and the two driving coils 30 are arranged on a group of two adjacent side walls of the lens support 20; there are two driving magnets 40, and the two driving magnets 40 are arranged on the base assembly 10 corresponding to the two driving coils 30. When the lens driving device in the present application is used, since the weight of the driving coil 30 is relatively low relative to the weight of the driving magnet 40, after the positions of the driving magnet 40 and the driving coil 30 are exchanged compared with the traditional lens driving device, it can be more conducive to the driving of the lens support 20. At the same time, since the driving magnet 40 in the present application is arranged on the base assembly 10 instead of the lens support 20, the size of the driving magnet 40 can be enlarged as much as possible within a limited space, and the effect of the driving magnet 40 and the driving coil 30 can be effectively improved, and the driving force of the lens driving device can be improved. Therefore, the lens driving device in the present application has a greater driving force than the transmission lens driving device. In addition, since at least a portion of the FPC in the present application is disposed on the lens support body 20 and another portion is disposed on the base assembly 10, the lens support body 20 can effectively ensure a stable electrical connection of the driving coil 30 during movement.

[0040] Specifically, the lens driving device further includes a guide assembly 60, one of the lens support 20 and the base assembly 10 is provided with the guide assembly 60, and the other is provided with a guide groove 61 corresponding to the guide assembly 60. By providing the guide assembly 60, it is ensured that the lens support 20 can move along a preset direction under the interaction of the driving magnet 40 and the driving coil 30 without deflection during the movement, thereby effectively ensuring the performance of the lens driving device.

[0041] In a specific embodiment of the present application, the guide assembly 60 includes at least two guide slide shafts 62, the two guide slide shafts 62 are arranged on a set of diagonals of the base assembly 10, and the lens support body 20 is provided with two guide grooves 61 corresponding to the two guide slide shafts 62. In addition, the two corners of the base assembly 10 corresponding to the ends of the side walls of the two lens support bodies 20 corresponding to the two drive coils 30 that are away from each other are respectively provided with guide slide shafts 62. That is to say, in the present application, the ends of the two adjacent side walls of the lens support body 20 where the two drive coils 30 are located that are away from each other are respectively provided with guide grooves 61, and the two guide grooves 61 correspond to different guide slide shafts 62. At the same time, the two guide slide shafts 62 are located on the same side of a diagonal line of the base assembly 10. That is to say, although the guide slide shafts 62 are arranged corresponding to a set of diagonals of the base assembly 10 in this embodiment, the two guide slide shafts 62 are not located on the diagonals of this set of diagonals, but are both located on the side of the diagonal line close to the drive coil 30 or the drive magnet 40. The purpose of such arrangement is to ensure that the lens support body 20 can be closer to the base assembly 10 and the angle between the two side walls of the driving magnet 40 under the action of the magnetic suction sheet 70 and the driving magnet 40, thereby ensuring that the force on the lens support body 20 can be more stable through the cooperation of the guide slide shaft 62 and the guide groove 61, and ensuring that the lens support body 20 will not translate in the direction perpendicular to the optical axis during use.

[0042] Preferably, the guide slide shaft 62 is made of ceramic material. This arrangement can effectively reduce the friction between the lens support body 20 and the guide slide shaft 62, thereby ensuring that the movement of the lens support body 20 is smoother.

[0043] Optionally, the lens driving device further includes at least two magnetic sheets 70, and at least one magnetic sheet 70 is respectively provided on the side of each driving coil 30 away from the driving magnet 40. By such a configuration, it can be ensured that the lens support body 20 can be more fully in contact with the guide slide shaft 62 under the interaction of the magnetic sheet 70 and the driving magnet 40, thereby ensuring that the guide slide shaft 62 can better guide the lens support body 20. In other words, in the present application, the magnetic sheet 70 and the driving magnet 40 are mutually attracted.

[0044] In a specific embodiment of the present application, the driving coil 30 and its corresponding magnetic sheet 70 are respectively arranged on both sides of the FPC board 50. This arrangement can effectively prevent the magnetic sheet 70 from affecting the electrical connection between the driving coil 30 and the FPC board 50. In addition, this arrangement can also provide a mounting groove corresponding to the magnetic sheet 70 on the lens support body 20, thereby effectively preventing the driving coil 30 from protruding outward, so as to ensure that the internal structure of the lens driving device is more compact, and is conducive to the miniaturization design of the lens driving device.

[0045] Specifically, the FPC board 50 includes a fixed portion 51, a connecting portion 52 and a movable portion 53 connected in sequence, the fixed portion 51 is arranged on the base assembly 10, and the movable portion 53 is arranged on the lens support body 20. When the lens support body 20 moves relative to the base assembly 10, at least a portion of the connecting portion 52 is deformed. In the present application, since the driving coil 30 will generate induction with the driving magnet 40 after being energized, the lens support body 20 will move along the optical axis under the interaction between the driving coil 30 and the driving magnet 40, thereby realizing the focusing of the lens. Therefore, by providing a deformable portion on the FPC board 50, the resistance of the lens support body 20 when it moves relative to the base assembly 10 can be reduced, thereby ensuring that the movement of the lens support body 20 is smoother.

[0046] In a specific embodiment of the present application, the connecting portion 52 includes a first section 521, a second section 522 and a third section 523 connected in sequence, the end of the first section 521 away from the second section 522 is connected to the fixed portion 51, the end of the third section 523 away from the second section 522 is connected to the movable portion 53, at least a portion of the third section 523 is arranged on the lens support body 20, and at least the first section 521 and the second section 522 have a bending structure. By arranging the bending structure on the first section 521 and the second section 522, it can be ensured that when the lens support body 20 moves relative to the base assembly 10 for focusing, at least a portion of the bending structure of the first section 521 and the second section 522 can be deformed, thereby ensuring that the movable portion 53 of the FPC board 50 will not be separated from the lens support body 20, thereby ensuring the stable electrical connection between the FPC board 50 and the driving coil 30 and the performance of the lens driving device. Moreover, the deformation of the bending structure can also reduce the influence of the FPC board 50 on the lens support body 20 during the movement of the lens support body 20, further release the stress of the FPC board 50, and reduce the interference of the stress concentration of the FPC board 50 on the focusing movement of the lens support body 20, so as to ensure that the movement of the lens support body 20 is smoother.

[0047] Preferably, the third section 523 is arranged on the top surface of the lens support body 20 and is electrically connected to the metal connector 80 and the aperture adjustment part 200. In addition, one end of the first section 521 away from the second section 522 is arranged on the outer side wall of the base assembly 10, and one end of the first section 521 connected to the second section 522 is arranged in the accommodation space; one end of the second section 522 connected to the first section 521 is arranged corresponding to the bottom surface of the lens support body 20, and one end of the second section 522 connected to the third section 523 bypasses the outer side wall of the lens support body 20 and is connected to the third section 523. By such arrangement, when the lens support body 20 moves relative to the base assembly 10, since the third section 523 is arranged on the top surface of the lens support body 20 and is connected to the movable part 53, when the connecting part 52 of the FPC board 50 is deformed, it will not affect the movable part 53, thereby ensuring the stable connection between the movable part 53 and the lens support body 20.

[0048] Optionally, the portion of the lens support body 20 corresponding to the second section 522 on the bottom surface thereof is provided with an avoidance groove 21. This arrangement not only ensures that the internal structure of the lens driving device is more compact, but also ensures that the FPC board 50 does not affect the height of the lens support body 20 in the optical axis direction, thereby effectively ensuring the performance of the lens driving device.

[0049] In a specific embodiment of the present application, one end of the metal connector 80 is connected to the portion of the third section 523 located on the top surface of the lens support body 20. Figure 1 As shown, in the present application, an aperture adjustment part 200 is arranged on the top of the lens support body 20, and the aperture adjustment part 200 is used to adjust the aperture size of the lens. At the same time, the aperture adjustment part 200 is fixedly arranged on the top of the lens support body 20 and can move with the lens support body 20.

[0050] Preferably, the lens driving device further comprises: at least two magnetic shielding sheets 90, at least one magnetic shielding sheet 90 is respectively arranged on the side of each driving magnet 40 away from the driving coil 30; and a housing 100, the housing 100 is covered on the base assembly 10, and the housing 100 is provided with an escape opening 110 corresponding to the aperture adjustment part 200. Such an arrangement can not only prevent the lens driving device from magnetic leakage, but also effectively improve the magnetic field strength.

[0051] Of course, in the present application, the fixing portion 51 of the FPC board 50 may also be arranged around the outside of the shell, so as to facilitate the electrical connection between the FPC board 50 and other parts of the camera module.
