Detailed ways

It should be noted that the embodiments in the present application and the features of the embodiments may be combined with each other in the case of no conflict. The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

In the present invention, unless otherwise stated, the directional words used such as "upper, lower, top, bottom" are usually for the directions shown in the drawings, or for the components themselves in vertical, In terms of vertical or gravitational direction; similarly, for the convenience of understanding and description, "inner and outer" refers to the inner and outer relative to the contour of each component itself, but the above-mentioned orientation words are not used to limit the present invention.

In order to solve the problem of poor use performance of the camera device in the prior art, the present application provides an anti-shake structure, an anti-shake system and a camera device.

Wherein, the camera device includes an anti-shake system, and the anti-shake system includes an anti-shake structure. By using the anti-shake system in the present application, the anti-shake performance of the camera device can be effectively improved, and the occurrence of blurred and unclear images taken by the camera device can be avoided.

As shown in FIG. 1 to FIG. 12 , the anti-shake structure in the present application includes a casing 10 and a base 20 , the casing 10 is covered on the base 20 and forms an accommodating space with the base 20 , and the anti-shake structure also includes an anti-shake structure arranged in the casing 20 . The lens support 30, the frame 40, the lateral magnet 50, the lateral coil 60, the magnetic attraction plate 70 and the plurality of balls 80 in the space, wherein the lateral magnet 50 is arranged on one side of the lens support 30; The coil 60 is disposed on the frame 40 corresponding to the lateral magnet 50, so that the lens support 30 is movably disposed on the frame 40 along the Z direction; a plurality of balls 80 are disposed between the frame 40 and the lens support 30, so that the lens The support body 30 slides smoothly relative to the frame 40 ; the magnetic attraction plate 70 is disposed on the side of the lateral coil 60 away from the lateral magnet 50 .

When using the anti-shake structure of the above structure, since the mounting wall and the outer side walls of the two lens supports 30 adjacent to the mounting wall are provided with at least one ball 80, when the lens support 30 moves relative to the frame 40 in the Z direction , the balls 80 on different side walls can ensure that the lens support 30 can move more flexibly, and can also reduce the friction force between the lens support 30 and the frame 40 . In addition, because the anti-shake structure also has a magnetic absorption plate 70, and the magnetic absorption plate 70 can generate a spatial adsorption effect with the opposite lateral magnet 50. That is, a certain pulling and adsorption function is generated for the AF drive module. Therefore, the lens support body 30 will always be attracted to the side of the frame 40 with the lateral coils 60 when moving relative to the frame 40 . The advantage of this is that, while the balls 80 are used as the force bearing point, it is not necessary to install the balls 80 at other positions except the side where the lateral magnet 50 is located, and only the lens support 30 at the corners of the other positions is required. It is sufficient to keep a certain clearance margin with the frame 40 .
