Embodiment Construction

[0019] The present invention will be further described below in conjunction with specific embodiments.

[0020] Such as figure 1 figure 2 image 3 As shown, a closed-loop dual-drive autofocus device for dual cameras, including:

[0021] The base 1, as the main body, is used to carry other components;

[0022] The double-lens supporting body 2 has double receiving cavities and one side is a driving surface 3. The double-lens supporting body 2 is nested in the base 1, and is used to carry two lens units and carry the lens unit to move;

[0023] The Hall sensing magnet 4 is arranged at the center of one side of the driving surface 3 of the double-lens support body, and is used for sensing the Hall signal;

[0024] The driving magnet 5 is provided with two groups, symmetrically distributed on the double-lens support driving surface 3 on both sides of the Hall sensing magnet 4 with the center line of the double-lens support 2 as the center, and is used to drive the double-lens...

Abstract

The invention discloses a closed-loop dual-drive autofocus device for dual cameras, which includes an iron shell, a dual-lens support body, a Hall sensor magnet, a drive magnet, a Hall sensor, a drive coil, a flexible circuit board, and a circuit board reinforcement board and base. The beneficial effects of the present invention are: gradually realize the triangular vision photography method of personnel, can realize more accurate photo framing, and obtain better photographic quality; The camera uses an autofocus device, which can more effectively realize the development and application of such technologies. The closed-loop single-drive autofocus device can realize accurate dual-lens drive, making the focus clearer, achieving a better viewfinder range, and taking better photos.

Description

technical field [0001] The invention relates to a closed-loop dual-drive autofocus device used by dual cameras, especially used on a camera device similar to eyes. Background technique [0002] The voice coil motor is a device that uses the interaction between the magnetic field from the permanent magnet steel and the magnetic poles in the magnetic field generated by the energized coil conductor to generate regular motion, and is widely used in mobile phone cameras. However, in the various photographic devices used at present, all adopt the structure of a camera, and a single camera can only take a certain range of photos at a time, which cannot be completely consistent with what the eyes see; in the future, the high-tech requirements of photos Driven by and future 3D technology, the camera method that simulates the human eye is gradually entering the application. Through the use of two cameras and the simulation of a more advanced triangulation algorithm, the framing and fo...
