Problems solved by technology

However, there is still a lot of room for improvement in accuracy. In addition, the anti-shake structure of the traditional optical lens needs to be powered on for a long time to keep it in the center. In the energized state, thereby increasing the load of the anti-shake structure and shortening the service life of the anti-shake mechanism

Abstract

The invention discloses a lens anti-shake apparatus with a self-locking structure. The lens anti-shake apparatus comprises a base, wherein the base is connected with a supporting frame; a lens assembly is arranged between the supporting frame and the base; the lens assembly comprises a lens supporting base; a transverse driving assembly and a longitudinal driving assembly are arranged between the base and the lens supporting base; the transverse driving assembly comprises a transverse driving magnet assembly and a transverse driving coil; the longitudinal driving assembly comprises a longitudinal driving magnet assembly and a longitudinal driving coil; a transverse induction assembly and a longitudinal induction assembly are also arranged between the supporting frame and the base; the transverse induction assembly comprises a transverse induction magnet and a transverse induction hall element; the longitudinal induction assembly comprises a longitudinal induction magnet and a longitudinal induction hall element; and the self-locking structure which is capable of switching the working state and non-working state of the anti-shake apparatus and capable of being separated from or clamped with the lens assembly is also arranged on the base. The lens anti-shake apparatus is simple in structure, high in anti-shake precision and long in service life.

Description

【Technical Field】 [0001] The invention relates to a lens anti-shake device with a self-locking structure. 【Background technique】 [0002] In the field of optical lenses, anti-shake technology is more and more widely used in environments with relatively large vibrations, such as in cars, sports cameras and some road monitoring. There are many ways of anti-shake, just change the light transmission path or the light projection path. The main products in the industry are lens anti-shake, CCD anti-shake, electronic anti-shake, and whole machine anti-shake. [0003] The realization of anti-shake is basically achieved by compensation, which compensates for the deviation of light caused by jitter. There is a gyroscope on the anti-shake structure. The device senses the change of external jitter and feeds it back to the chip, so that the anti-shake mechanism moves the corresponding change to compensate. The movement of the anti-shake mechanism depends on the Hall element feedback, and its ...
