Embodiment Construction

[0054] Hereinafter, exemplary embodiments according to the present application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application, and it should be understood that the present application is not limited by the example embodiments described herein.

[0055] Application overview

[0056] As mentioned above, the existing driving elements used to drive various components in the camera module, such as optical lenses and zoom components, are electromagnetic motors, such as voice coil motors (Voice Coil Motor: VCM), shape memory alloy drivers ( Shape of Memory Alloy Actuator: SMA), etc. Since traditionally, the camera module is arranged along the thickness direction of electronic devices, such as mobile phones, so the various components in the camera module tend to be thin and miniaturized. In this case...

Abstract

The periscopic camera module comprises a light turning element, a light emitting element and a light receiving element, a zoom lens group including a fixed portion, a zoom portion, and a focusing portion; a photosensitive assembly corresponding to the zoom lens group; and the driving assembly comprises a driving shell, a first driving element and a second driving element, the first driving element and the second driving element are located in the driving shell, the first driving element and the second driving element are arranged on the first side of the zoom lens group, and the first driving element and the second driving element are oppositely arranged. Particularly, the periscopic camera module adopts a piezoelectric actuator as a driving element to provide enough driving force. And moreover, the piezoelectric actuators are arranged in the periscopic camera module by adopting a reasonable arrangement scheme, so that the structure and size requirements of the periscopic camera module are met.

Description

technical field [0001] The present application relates to the field of camera modules, and in particular, to a periscope camera module, wherein the periscope camera module adopts a piezoelectric actuator as a driving element to provide a sufficiently large driving force. In addition, a reasonable arrangement scheme is adopted to arrange the piezoelectric actuator in the periscope camera module, so as to meet the structure and size requirements of the periscope camera module. Background technique [0002] With the popularization of mobile electronic devices, the related technologies of camera modules used in mobile electronic devices to help users acquire images (eg, videos or images) have been rapidly developed and advanced, and in recent years, camera modules Modules have been widely used in many fields such as medical treatment, security, industrial production and so on. [0003] In order to meet more and more extensive market demands, high pixel, large chip, and small si...
