Imaging lens driving module and electronic device

Abstract

The invention discloses an imaging lens driving module and an electronic device. The imaging lens driving module comprises a base, a shell, a driving mechanism and a damping element, the base is provided with an open hole, the shell is provided with a central open hole, and the central open hole of the shell corresponds to the open hole of the base. The shell comprises a plastic frame part and a metal structure part, the plastic frame part is coupled with the base, and the metal structure part is provided with a plurality of pins extending towards the base. The driving mechanism is arranged in the shell and used for driving the lens unit to move in the direction parallel to the optical axis. The damping element is connected to the pins and the lens unit. Wherein the shell is formed by embedding and injecting the plastic frame part and the metal structure part, and the pins are closer to the optical axis than the metal structure parts except the pins. The electronic device is provided with the imaging lens driving module.

Description

technical field [0001] The invention relates to an imaging lens driving module, in particular to an imaging 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 pixels 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 photose...

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
