Problems solved by technology

[0002] Most of the existing periscope motors with multiple groups of lenses are controlled in a single way. For example, if there are two moving lens groups, they are all controlled by the same driving method, such as electromagnetic drive or piezoelectric drive. It is difficult to control when cooperating with focusing, and it is impossible to achieve fast focusing
In addition, the existing periscope motors are too bulky and costly to produce

Abstract

The invention discloses a lens driving structure, which comprises a frame, and a first carrier, a second carrier, a first driving device and a second driving device which are arranged in the frame. The two ends of the front side of the first carrier are movably arranged in the frame through sliding rails respectively, a first driving device is installed at one end of the front side of the first carrier, and the first driving device is connected with and drives the first carrier to move in the frame along the sliding rails. A second carrier and a second driving device are arranged on the rear side of the first carrier, and the second driving device is connected with and drives the second carrier to move on the rear side of the first carrier. The first driving device drives the first carrierand the second carrier to achieve synchronous movement of a second lens installation body and a third lens installation body so as to realize a zooming function, and while the second lens installation body and the third lens installation body move synchronously, the third lens installation body is driven by the second driving device to achieve higher-precision focusing.

Description

technical field [0001] The invention relates to the field of motors, in particular to a lens driving structure, a photographic device, and electronic products. Background technique [0002] Most of the existing periscope motors with multiple groups of lenses are controlled in a single way. For example, if there are two moving lens groups, they are all controlled by the same driving method, such as electromagnetic drive or piezoelectric drive. It is difficult to control when cooperating with focusing, and fast focusing cannot be achieved. In addition, the existing periscope motors are too bulky and costly to produce. Contents of the invention [0003] The purpose of the present invention is to provide a lens driving structure, a photographic device, and an electronic product to solve the problems in the prior art. [0004] The technical problem solved by the present invention can adopt following technical scheme to realize: [0005] A lens driving structure, including a ...
