Abstract

The invention belongs to the technical field of camera brake devices, in particular to a split-type low-power-consumption small automatic focusing brake device. The split-type low-power-consumption small automatic focusing brake device includes a shell, a spring, a picture sensor carrier, at least one magnet, at least one independent coil and an elastic circuit board; the spring, the picture sensor carrier and the elastic circuit board form a spring vibrator system which has uniaxial displacement freedom degrees, the magnets are arranged on the inner wall of the shell, the independent coils are arranged on the picture sensor carrier and correspond to the magnets, and after being powered on, the independent coils are affected by ampere force in magnetic fields of the magnets. The structureof the split-type low-power-consumption small automatic focusing brake device cannot generate non-linear friction and has the advantages of being good in dust-prevention and heat-dissipation effect.

Description

technical field [0001] The invention belongs to the technical field of camera brakes, and in particular relates to a split-type low-power consumption small auto-focus brake. Background technique [0002] In recent years, portable photographic devices with autofocus functions have become very popular, and have basically become standard functions of photographic devices. When the subject is at different distances during the shooting process, the auto focus function can effectively improve the resolution of the closer subject in the image and improve the photo quality of the close-up. On the other hand, the auto focus function can blur the image of objects at other distances, making the subject stand out more in the photo. [0003] The traditional auto focus system achieves the effect of changing the optimal object distance (Optimal Object Distance) by moving the position of the entire lens or some lenses in the lens. In recent years, traditional mainstream actuators can prec...
