Problems solved by technology

However, the design of the threaded part will increase the overall volume of the lens assembly and the complexity of assembly
In addition, the lens components on the market today commonly use a voice coil motor (VCM) as the lens driving device for lens autofocus. Requirements, in the assembly process of the lens drive device and the lens itself, multiple alignment and calibration steps are required to accurately assemble the multiple parts one by one, thus limiting the production efficiency and manufacturing yield of the lens drive device

Abstract

The invention provides a lens driving module and an electronic device. The lens driving module includes a base, a shielding cover, a driving mechanism, a space maintaining element and a damping element. The base has an opening.The shielding cover is coupled with the base, and the shielding cover has central openings corresponding to openings. The driving mechanism is arranged in the shielding cover to drive the lens unit to move along the direction parallel to the optical axis.The space maintaining element is in physical contact with the shielding cover. The space maintaining element includes a plastic frame part and a metal structure part. The metal structure part has a plurality of pins extending toward the base, and the space maintaining element is made by inserting and injecting the plastic frame part and the metal structure part. The damping element is connected to the pin and the lens unit. The pins are closer to the optical axis than the metal structures other than the pins.

Description

technical field [0001] The invention relates to a lens driving module, in particular to a lens driving module suitable for electronic devices. Background technique [0002] With the improvement of semiconductor process technology, the performance of electronic photosensitive elements has been improved, and the pixel size can reach a smaller size. Therefore, optical lenses with high imaging quality have become an indispensable part. In addition, with the rapid development of technology, the application range of mobile phone devices equipped with optical lenses is wider, and the requirements for optical lenses are also more diverse. [0003] Existing lens components generally include a lens barrel and a lens base, which are assembled with each other through threaded parts. Through the rotation of the lens barrel, the position of the lens barrel relative to the lens base can be adjusted, so as to focus and project the image onto the imaging surface of the photosensitive elemen...
