Magnetic mini anti-shake head

Abstract

The present invention relates to the field of anti-shake platform, in particular to a magnetic suction miniature anti-shake platform, comprising an outer base body, an inner base body, an elastic support and a camera module; the outer base body is provided with a magnetically conductive part and at least The three balls are rotatably connected to the outer base body, and the magnetic conductive parts are arranged adjacent to the balls; the inner base body is provided with a positioning magnet and a spherical limit surface, the first magnet and the magnetic conductive part are arranged oppositely, and the positioning magnet attracts the guide The magnetic part makes the ball abut against the limit surface; the elastic bracket includes a fixed part, an elastic component and a movable part connected in sequence, the fixed part is arranged on the outer base body, the elastic component has elasticity, the movable part is arranged on the inner base body, and the camera The module is connected to the moving parts; the attraction of the positioning magnet to the magnetically conductive parts can not only ensure that the outer base and the inner base are connected by ball rotation, but also this design is less sensitive to the manufacturing error of the anti-shake head The impact of anti-shake performance is low.

Description

technical field [0001] The invention relates to the field of anti-shake cloud platforms, in particular to a magnetic suction miniature anti-shake platform. Background technique [0002] In recent years, small mobile devices with camera functions have become very popular, and their application scope has been expanding, including aerial photography, action cameras, and driving recorders. The device includes at least one compact camera module. Therefore, the market for said modules is large and the growth is steadily increasing. [0003] When taking photos and videos, the photos and videos taken by the device are likely to be blurred or shaken by external vibrations, affecting the quality of the photos and videos. This problem is exacerbated when the vibrations are intense, or in low light situations. [0004] In order to solve the above problems, many small anti-shake technologies have appeared on the market. Among them, the effect of improving image quality by mechanicall...

Problems solved by technology

In addition, the components and assembly precision required by the mechanical structure of the technology are extremely high

Especially when the accuracy is insufficient and the error is too large, the friction of the contact structure will be too large, which will affect the anti-shake performance and power consumption

Therefore, the mechanical structure of the described technology is complex, requires more space, the manufacturing process is difficult, and the cost is higher
