Abstract

The invention provides a rapid automatic zooming device for adjusting the position of a lens, and the device comprises a fixed seat which is provided with a pedestal at the lower part and a step seatat the upper part; a moving seat which is arranged in the step seat and is detachably connected with the lens; a large gear the middle of which is provided with a focusing cylinder, wherein the outerside of the focusing cylinder is in threaded connection with the step seat, the step seat is provided with an axially-arranged guide groove, and the movable base is fixedly provided with a guide nailcapable of being matched with the guide groove; the transmission mechanism is used for providing power for the rotation of the gearwheel; and the bottom cover is arranged at the joint of the base andthe step seat. According to the quick automatic zooming device, under the condition that the power and the rotating speed of the motor are not changed, the focusing speed of the mechanism is increasedthrough a gear and thread pair combined mechanism.

Description

technical field [0001] The invention belongs to the technical field of automatic focusing, in particular to a fast automatic zooming device. Background technique [0002] In order to realize the camera and video functions of the electronic device, it is usually necessary to install a lens module in the electronic device, and the lens module generally includes a lens and a photosensitive element. When assembling the lens module, it is necessary to focus on the lens module first, that is, use the focusing device to fine-tune the distance between the lens of the lens module and the photosensitive element, so that the focusing surface of the lens is aligned with the sensing surface of the photosensitive element. To whom to achieve the best image quality. [0003] At present, the commonly used focusing mechanisms are mostly screw drive zoom and cam curve drive zoom. Due to the limitation of lead and pressure angle, the focus speed is low. In order to increase the focus speed, it...
