[0028] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. The present invention will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0029] It should be pointed out that, unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present application belongs.

[0030] In the present invention, unless otherwise stated, the orientation terms such as "upper, lower, top, bottom" are usually in the directions shown in the drawings, or in the vertical, perpendicular or gravitational directions of the components themselves; similarly, for the convenience of understanding and description, "inner, outer" refer to the inner and outer of the contours of the components themselves, but the above orientation terms do not limit the present invention.

[0031] In order to solve the problems of small displacement amount, difficult jitter precision control and poor use performance of the jitter correction mechanism in the prior art, the present application provides a jitter correction mechanism, a camera device and an electronic device.

[0032] Moreover, the camera device in the present application has the following jitter correction mechanism, and the electronic device in the present application may be a mobile phone, a tablet computer, a notebook computer, etc. having the camera device of the present application.

[0033] Such as Figures 1 to 6As shown in the figure, the jitter correction mechanism in the present application includes a base assembly 10, a moving seat 20, a lens support 30, a first limiting and guiding assembly 40, a second limiting and guiding assembly 50, and a driving assembly 60. The lens support 30 is movably arranged between the moving seat 20 and the base assembly 10; the moving seat 20 is connected to the base assembly 10 through the first limiting and guiding assembly 40; the moving seat 20 is connected to the lens support 30 through the second limiting and guiding assembly 50; at least a part of the driving assembly 60 is arranged on the base assembly 10, and at least another part of the driving assembly 60 is correspondingly arranged on the moving seat 20 and / or the lens support 30; when the driving assembly 60 is powered on, the lens support 30 can move relative to the moving seat 20 and / or the lens support 30 can move relative to the base assembly 10 together with the moving seat 20.

[0034] When using the jitter correction mechanism in the present application, since when the driving assembly 60 is powered on, the lens support 30 and the moving seat 20 can move relative to the base assembly 10 together under the action of the driving assembly 60 or the lens support 30 can move relative to the moving seat 20 and the base assembly 10 alone, the anti-shake adjustment of the imaging device can be realized. At the same time, since the jitter correction mechanism in the present application further includes a first limiting and guiding assembly 40 and a second limiting and guiding assembly 50, the first limiting and guiding assembly 40 and the second limiting and guiding assembly 50 can play a role in guiding and limiting the movement of the moving seat 20 and the lens support 30, thereby improving the jitter accuracy. Therefore, the jitter correction mechanism in the present application effectively solves the problems of small displacement, difficult jitter accuracy control, and poor use performance of the jitter correction mechanism in the prior art.

[0035] Specifically, when the lens support 30 moves relative to the base assembly 10 together with the moving seat 20, the moving seat 20 drives the lens support 30 to move along the first limiting and guiding assembly 40; when the lens support 30 moves relative to the moving seat 20, the lens support 30 moves relative to the moving seat 20 along the second limiting and guiding assembly 50. And, the first limiting and guiding assembly 40 includes at least one first guiding rod 41, the second limiting and guiding assembly 50 includes at least one second guiding rod 51, and there is an angle greater than 0 degrees between the first guiding rod 41 and the second guiding rod 51. That is to say, in the present application, the movement direction when the moving seat 20 and the lens support 30 move relative to the base assembly 10 together is different from the movement direction when the lens support 30 moves relative to the moving seat 20 and the base assembly 10 alone. By such a setting, it can be ensured that the jitter correction mechanism in the present application can realize jitter correction in different directions. And, it should also be noted that in the present application, although the lens support 30 has two movement modes, one is to move with the moving seat 20, and the other is to move relative to the moving seat 20, in the actual use process, these two movement modes of the lens support 30 can be carried out simultaneously.

[0036] Meanwhile, in the present application, by providing the first guide rod 41 and the second guide rod 51, the displacement of the jitter correction mechanism can also be effectively increased, so that large-distance anti-shake of the lens support 30 can be achieved.

[0037] Specifically, the first guide rod 41 extends along the X-axis direction; the second guide rod 51 extends along the Y-axis direction. That is to say, when the moving seat 20 and the lens support 30 move, the lens support 30 and the moving seat 20 move together along the X-axis direction. When the lens support 30 moves relative to the moving seat 20, the lens support 30 moves along the Y-axis direction. By such an arrangement, jitter correction of the jitter correction mechanism in the XY plane can be effectively achieved.

[0038] In a specific embodiment of the present application, both the first guide rod 41 and the second guide rod 51 are two, and the two first guide rods 41 are symmetrically arranged relative to the moving seat 20; and / or the two second guide rods 51 are symmetrically arranged relative to the moving seat 20. By such an arrangement, it can be ensured that the forces on the moving seat 20 and the lens support 30 are more stable, and the stability of the lens support 30 and the moving seat 20 during movement is ensured. At the same time, by such an arrangement, it can also effectively prevent the moving seat 20 and the lens support 30 from being skewed during movement.

[0039] Moreover, in this embodiment, the two first guide rods 41 and the two second guide rods 51 are respectively located on four different sides of a quadrilateral. Or rather, the extension lines of the two first guide rods 41 and the extension lines of the two second guides can enclose a quadrilateral.

[0040] Optionally, the moving seat 20 is respectively provided with at least one U-shaped groove and at least one V-shaped groove 71 corresponding to the two first guide rods 41, and one of the first guide rods 41 cooperates with the U-shaped groove, and the other first guide rod 41 cooperates with the V-shaped groove 71. Or, the moving seat 20 is respectively provided with at least one sliding platform 72 and at least one V-shaped groove 71 corresponding to the two first guide rods 41, and one of the first guide rods 41 cooperates with the sliding platform 72, and the other first guide rod 41 cooperates with the V-shaped groove 71.

[0041] Optionally, the lens support 30 is respectively provided with at least one U-shaped groove and at least one V-shaped groove 71 corresponding to the two second guide rods 51, and one of the second guide rods 51 cooperates with the U-shaped groove, and the other second guide rod 51 cooperates with the V-shaped groove 71. Or the lens support 30 is respectively provided with at least one sliding platform 72 and at least one V-shaped groove 71 corresponding to the two second guide rods 51, and one of the second guide rods 51 cooperates with the sliding platform 72, and the other second guide rod 51 cooperates with the V-shaped groove 71.

[0042] In this application, the purpose of setting the V-shaped groove 71 that cooperates with the first guide rod 41 and the second guide rod 51 is to use the V-shaped groove 71 to play a role in installing and positioning the first guide rod 41 and the second guide rod 51, so as to ensure that when the moving seat 20 moves along the first guide rod 41 or the lens support 30 moves along the second guide rod 51, the second guide rod 51 will not displace, and thus the guiding effect on the moving seat 20 and the lens support 30 can be ensured. For the other first guide rod 41 and the second guide rod 51, if both the two first guide rods 41 and the two second guide rods 51 are within the V-shaped groove 71, it is easy to occur the phenomenon of jamming or being stuck, which will cause excessive frictional resistance and interference to the guiding movement, thus affecting the jitter correction effect of the jitter correction mechanism. By setting the U-shaped groove that cooperates with it, the occurrence of jamming or being stuck can be reduced. Of course, in this application, the sliding platform 72 can also be set to replace the U-shaped groove, and by setting the sliding platform 72, the contact area between the first guide rod 41 and the moving seat 20 and the contact area between the second guide rod 51 and the lens support 30 can be effectively reduced. By setting the high-precision sliding platform 72, the assembly flatness / parallelism of the first guide rod 41 and the second guide rod 51 can be further improved, so that the movement of the moving seat 20 and the movement of the lens support 30 can be more smooth and the driving accuracy can be higher.

[0043] In a specific embodiment of this application, each guide rod corresponds to two V-shaped grooves or two U-shaped grooves or one sliding platform.

[0044] Specifically, the base assembly 10 has a plurality of mounting protrusions 11, and there is a mounting space 12 between two adjacent mounting protrusions 11. At least a part of the driving assembly 60 is accommodated in the mounting space 12. The two ends of different first guide rods 41 are respectively connected to two different and adjacent mounting protrusions 11. In a specific embodiment of this application, the base assembly 10 has four mounting protrusions 11, two of the mounting protrusions 11 are respectively connected to the two ends of a first guide rod 41, and the other two mounting protrusions 11 are connected to the two ends of another first guide rod 41. At the same time, the mounting protrusion 11 is provided with a mounting hole corresponding to the first guide rod 41. It should also be noted that in this application, the connection between the first guide rod 41 and the mounting protrusion 11 is a fixed connection, so as to ensure that the moving seat 20 will only move along the first guide rod 41 and will not rotate with the first guide rod 41.

[0045] Moreover, the U-shaped groove, V-shaped groove 71 or sliding platform 72 on the moving seat 20 is arranged on the side of the moving seat 20 away from the lens support 30. Since the first guide rod 41 is fixedly arranged on the base assembly 10 in this application, such an arrangement can also limit the moving seat 20 in the Z-axis direction to a certain extent through the cooperation between the first guide rod 41 and the U-shaped groove or V-shaped groove 71 on the moving seat 20, thereby preventing the separation between the moving seat 20 and the lens support 30, further ensuring that the second guide rod 51 can guide and limit the lens support 30, and avoiding the disengagement of the second guide rod 51 from the lens support 30.

[0046] Specifically, the driving assembly 60 includes a plurality of driving coils 61 arranged on the base assembly 10 and a plurality of driving magnets 62 arranged on the lens support 30 corresponding to the plurality of driving coils 61.

[0047] In a specific embodiment of this application, the first guide rod 41 is made of ceramic material, and the second guide rod 51 is made of metal material.

[0048] As an alternative to the above embodiment, in another specific embodiment of this application, both the first guide rod 41 and the second guide rod 51 are made of ceramic material, and the jitter correction mechanism further includes a metal sheet, which is arranged on the side of the moving seat 20 away from the lens support 30.

[0049] Specifically, the base assembly 10 includes: a base body 13, the base body 13 has a mounting protrusion 11, and the driving coil 61 is arranged on the base body 13; an upper cover 14, the upper cover 14 covers the base body 13 and forms an accommodation cavity with the base body 13, the moving seat 20 and the lens support 30 are arranged inside the accommodation cavity, the moving seat 20 is closer to the upper cover 14 relative to the lens support 30, and the metal sheet is embedded inside the upper cover 14.

[0050] In this application, such an arrangement can make the second guide rod 51 or the metal sheet adsorb the driving magnet 62, thereby ensuring the stable abutment between the moving seat 20 and the first guide rod 41, and at the same time ensuring the stable abutment between the lens support 30 and the second guide rod 51. Moreover, by making the first guide rod 41 and the second guide rod 51 made of ceramic material, the friction force received by the moving seat 20 and the lens support 30 can be effectively reduced. And embedding the metal sheet in the upper cover 14 can thin the thickness of the upper cover 14 and enhance the strength of the upper cover 14.

[0051] It should be noted that in the present application, a part of the second guide rod 51 can be embedded in the moving seat 20. Moreover, at the position where the driving coil 61 is arranged on the base body 13, an impact projection 15 is also provided, and one end of the impact projection 15 facing the driving magnet 62 has a magnet impact surface, so as to play a role in impact buffering and noise reduction. Further, a silica gel gasket 80 can be added on the side of the driving coil 61 facing the driving magnet 62, and an avoidance opening for avoiding the impact projection 15 can be provided at the position of the silica gel gasket 80 corresponding to the impact projection 15. Preferably, the surface of one end of the silica gel gasket 80 facing the driving magnet 62 is higher than the magnet impact surface.

[0052] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:
