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

Embodiment Construction

[0030] The present invention will be further described below in conjunction with accompanying drawing:

[0031] Such as Figure 1 to Figure 3As shown, a lens anti-shake device with a self-locking structure includes a base 1, and the base 1 is connected with a support frame 2 that can move in the lateral direction relative to it. The support frame 2 and the base 1 There is a lens assembly 3 that can move in the longitudinal direction relative to the support frame 2 and can move in the transverse direction with the support frame 2 relative to the base 1. The lens assembly 3 includes a lens support seat 31 for installing the lens 100, Between the base 1 and the lens support seat 31 are provided a transverse drive assembly 32 and a longitudinal drive assembly 33 which respectively drive the lens assembly 3 to move laterally and longitudinally. The transverse drive magnet assembly 321 and the transverse drive coil 322 opposite to the transverse drive magnet assembly 321 on the bas...

There is a horizontal drive assembly and a longitudinal drive assembly between them, the horizontal drive assembly includes a horizontal drive magnet assembly and a horizontal drive coil, the longitudinal drive assembly includes a longitudinal drive magnet assembly and a longitudinal drive coil, and a horizontal induction assembly and The longitudinal sensing component, the transverse sensing component includes a transverse sensing magnet and the transverse sensing Hall element, the longitudinal sensing component includes a longitudinal sensing magnet and a longitudinal sensing Hall element, and the base is also provided with a switch for switching anti- The self-locking structure of the working state and non-working state of the shaking device. The invention has the advantages of simple structure, high anti-shake precision and long 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 inside cars, sports cameras and some road monitoring. There are many ways of anti-shake, just change the transmission path of light or the path of light projection. The main products in the industry include lens anti-shake, CCD anti-shake, electronic anti-shake, and whole machine anti-shake. [0003] The implementation of anti-shake is basically achieved by compensation, which compensates for the deviation of light caused by shaking. 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 is fed back by the Ha...
