Abstract

The invention discloses a driving structure which comprises a frame, and a carrier assembly and a driving assembly are arranged in the frame. The carrier assembly comprises a first carrier and a second carrier arranged on the first carrier. The driving assembly comprises a first driving device and a second driving device, the first driving device is installed in the frame, the output end of the first driving device is connected with and drives the first carrier, the second driving device is installed on the first carrier, and the second driving device is connected with and drives the second carrier. The combination of a first driving motor and a second driving motor of different types is adopted to replace a traditional continuous zooming motor driving structure, and the focusing precisionis higher.

Description

technical field [0001] The invention relates to the field of periscope motors, in particular to a driving structure, a driving device and electronic equipment. Background technique [0002] Most of the existing continuous zoom driving mechanisms are a combined structure of two lenses, or a combined structure containing three lenses, wherein at least two lenses in such a driving mechanism are movable, and the driving methods between them are all They are driven separately; in the existing driving mechanism for realizing the continuous zoom function, two driving mechanisms are respectively used for the driving, generally the same type of driving method. [0003] The defect of the above-mentioned driving structure is that: the driving modes of the two groups of lenses each cause a positional deviation in the direction of the optical axis, which affects the imaging effect, cannot meet higher requirements for precision, and has a relatively slow focusing speed. Contents of the ...
