Abstract

The invention belongs to the technical field of camera brakes, and specifically relates to a split-type low-power small autofocus brake, which includes a housing, a spring, an image sensor carrier, at least one magnet, at least one independent coil, and an elastic circuit board, a spring, and an image sensor carrier . The elastic circuit board forms a spring vibrator system with one axis displacement degree of freedom. At least one magnet is arranged on the inner wall of the housing, and the independent coil is arranged on the image sensor carrier and correspondingly arranged with the magnet. Ampere's force acts on the magnetic field. The braking structure of the present invention does not generate nonlinear friction force, and has the characteristics of good dustproof and heat dissipation effects.

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 camera devices with an autofocus function have become very popular and have basically become a standard function of the camera 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 autofocus function can blur the image of objects at other distances, making the subject stand out more in the photo. [0003] The traditional autofocus 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 precisely ch...
