Abstract

The invention discloses a mobile phone lens zooming mechanism of a multilayer cymbal type piezoelectric driving assembly, and relates to the field of mobile phone shooting. A plurality of layers of cymbal type piezoelectric driving units are overlapped to form a driving assembly, and the driving assembly, a lens group, a lens support and a supporting base form a mobile phone lens zooming mechanism. The driving assembly is connected with the lens support and the supporting base, displacement deformation generated when the cymbal type piezoelectric driving unit is excited by external voltage isamplified through multi-layer superposition, the lens support is driven to move in the optical axis direction, and therefore zoom of the lens is achieved. The number of the driving assemblies is larger than two. Compared with an existing zoom system based on an electromagnetic voice coil motor, the zoom system based on the electromagnetic voice coil motor is more compact in structure, electromagnetic interference is not generated, displacement and angle adjustability of a lens optical device are achieved, and more convenience is brought to image shooting.

Description

technical field [0001] The invention relates to a mobile phone lens zoom mechanism driven by a multi-layer cymbal piezoelectric drive with an active zoom function, belonging to the field of electronic equipment. Background technique [0002] Taking pictures is one of the most commonly used functions of smartphones in daily life. People's requirements for image quality are constantly improving. In order to obtain clear and accurate images, zoom plays an important role. Every upgrade of mobile phone zoom technology can greatly improve the quality of mobile phones. The shooting level can adapt to the different focal length requirements of complex scenes. In mobile phone cameras, the focal length changes from the initial focal length to optical zoom. In optical zoom mobile phones, the optical zoom components of mobile phones are driven by voice coil motors at this stage. The voice coil motors use the electromagnetic force generated by the electric coil and the permanent magnet. ...
