Description
Technical Field
The invention relates to the field of anti-shake cloud platforms, in particular to a magnetic type miniature anti-shake cloud platform.
Background
In recent years, small-sized mobile devices with shooting functions are quite popular, and the application range is also continuously expanded, including aerial photography, motion cameras and automobile data recorders. The device comprises at least one Compact camera module (Compact camera module). Therefore, the market of the module is huge, and the growth is steadily promoted.
When taking pictures and films, the pictures and films taken by the device are likely to be blurred or shaken by external vibration, which affects the quality of the pictures and films. This problem is exacerbated when the vibrations are relatively intense, or in low light conditions.
In order to solve the above problems, many small-sized anti-shake technologies have appeared on the market. Among them, the effect of improving the picture quality is most excellent by mechanically compensating for the blurring and shaking of the image due to the vibration. The mechanical method may be to translate a set of lenses by an anti-shake actuator (refer to patents CN104204934A, US20140333784a1), or to rotate a set of lenses and an image sensor simultaneously (refer to patents CN102934021B, US9229244B2), to achieve an anti-shake effect. The second anti-shake effect using the rotary mechanical method is generally better than that of the first translational mechanical method, so the magnetic ball bearing structure of the multi-axis micro pan-tilt is mainly directed to the rotary method.
The rotary anti-shake actuator needs to have a multi-axis Rotational-Freedom (Rotational) mechanical structure, so as to achieve the movable effect of the lens, the image sensor and the like. Meanwhile, in order to alleviate the influence of external forces caused by acceleration in different directions or earth-core attraction on the movable structure in the actuator, the mechanical structure generally needs to be close to having no displacement Freedom (Translational dimensions-of-Freedom). In addition, a mechanical structure is required to have good fall resistance, and the mechanical structure must be able to withstand the fall risks that may occur when a small mobile device is normally used.
For the rotation type anti-shake camera module, the existing mechanical structure can be divided into two types. The first category (refer to patents: CN107450251A, CN208399865U) employs a plurality of inclined spring plates on a plurality of different planes, which achieve multi-axis rotational freedom and lower displacement freedom (higher displacement spring coefficient). The technology has the advantages of simple production process and low cost.
The second category (refer to patents: CN106353950B, CN108693677A, CN108881697A and CN103513492A) achieves the required multi-axis rotational freedom degree through a multi-group contact structure. Each of said sets of contact structures generally comprises a plurality of movable balls (refer to patent: CN103513492A) or at least two immobile balls (refer to patent: CN106353950B) and is responsible for the rotational freedom of a shaft. The advantage of this technique is that the displacement spring coefficient is very high, so different attitude differences and the change in the direction of the earth's core suction cause less influence on the anti-shake performance.
Although the first type of prior art can provide multi-axis rotational freedom, the rotational spring coefficient is generally large, so that power consumption is large, and battery life is reduced. In addition, the displacement spring coefficient of the first prior art is lower than that of the second prior art, so that the influence on the anti-shake performance caused by different attitude differences and the change of the earth core suction direction is larger.
In the second prior art (refer to patent nos.: CN106338873B, CN109752863A), when the number of anti-shake shafts is plural, this kind of technology requires plural sets of contact structures and connection structures for connecting the plural sets of structures. In addition, the mechanical structure of the technology requires extremely high precision of parts and assembly. Especially, when the precision is insufficient and the error is too large, the friction force of the contact structure is too large, and the anti-shake performance and the power consumption are affected. Therefore, the mechanical structure of the technology is complex, more space is needed, the manufacturing process is difficult, and the cost is higher.
