For convenience of explanation, a mobile phone may be described as a specific example of the mobile terminal 10000 according to the embodiment of the present application. It is understood that the mobile terminal 10000 can be other devices which are provided with the camera 1000 and the camera 1000 is equipped with the anti-shake mechanism 100, such as a tablet computer, an e-book reader, an MP3 player, an MP4 player, a vehicle-mounted computer, a desktop computer, a smart television, or a wearable device, besides a mobile phone.

It should be noted that the camera 1000 is used as a component commonly used by the mobile terminal 10000 such as a mobile phone, and the camera 1000 enables the mobile terminal 10000 to have a shooting function. Generally, the height direction of the camera 1000 coincides with the thickness direction of the mobile terminal 10000, and the height of the camera 1000 affects the thickness of the mobile terminal 10000. Therefore, how to reduce the height of the camera 1000 and further reduce the thickness of the mobile terminal 10000 has been a subject of research and development by researchers, and especially, the researchers pay more attention to the camera 1000 having the anti-shake function.

Specifically, the anti-shake mechanism 100 in the present application includes a first movable member 11, a first rolling element 12, and a second rolling element 13. In particular, the anti-shake mechanism 100 in the present application may be an OIS (optical Image stabilization) optical anti-shake mechanism 100, where the mobile terminal 10000 to which the anti-shake mechanism 100 is applied is not prone to capturing a blurred Image when the mobile terminal 10000 shakes, and the anti-shake mechanism 100 offsets handheld shake by moving the lens 200 or the chip in a targeted manner, so that the Image is maintained stable, and the OIS optical anti-shake is implemented. It can be understood that, in order to drive the lens 200 to move, the anti-shake mechanism 100 further includes a motor, which may be a ball-type optical anti-shake motor in this application, that is, the first rolling element 12 and the second rolling element 13 may be balls.

The anti-shake mechanism 100 is provided with a light-passing hole 10 so that light is incident from the light-passing hole 10, and the lens 200 mounted on the anti-shake mechanism 100 can be imaged. The anti-shake mechanism 100 includes a first movable member 11, the light-passing hole 10 can penetrate through the first movable member 11, and the first movable member 11 can be a plastic member, so that the anti-shake mechanism 100 is light in weight, simple to manufacture, and low in cost.

The first movable member 11 may include a first side 110 and a second side 111 opposite to each other, where the first side 110 of the first movable member 11 may be a side of the light incident surface, and the second side 111 corresponds to a side away from the first side 110. The first side 110 and the second side 111 are both arranged along the central axis L1 of the light passing hole 10.

The first rolling elements 12, i.e. balls, may be movably arranged on the first side 110 and correspondingly the second rolling elements 13 may be balls of the same size, which may be movably arranged on the second side 111. In some conventional embodiments, the first movable element 11, the first rolling element 12, and the second rolling element 13 are often stacked in a vertically stacked structure, and the overall height of the anti-shake mechanism 100 is difficult to reduce due to the component size and the height of the first rolling element 12 and the second rolling element 13. Therefore, in this application, along the center axis L1 direction of perpendicular to logical unthreaded hole 10, set up first rolling element 12 and second rolling element 13 into at least partial overlapping, make the overall structure of staggering from top to bottom of three promptly to can reduce the overall height of anti-shake mechanism 100, and then reduce camera 1000's height and mobile terminal 10000's thickness, promote the frivolous competitiveness of mobile terminal 10000 product in step.
