Publication number: 20210208363Abstract: This application provides a lens actuating apparatus, a periscope lens module including the lens actuating apparatus, and a photographing device including the periscope lens module. Light enters a lens group after being reflected, so that a direction of an optical axis of the lens group is different from a thickness direction of the photographing device, to eliminate a limitation of a length of the direction of the optical axis of the lens group on a thickness of the photographing device, and implement thinness of the photographing device. A translation motor and an axis-moving motor are disposed on a holder of the lens actuating apparatus, to implement focusing and anti-shake of the periscope lens module including an optical component and the lens actuating apparatus. In this application, the translation motor and the axis-moving motor are independent of each other. In this way, control efficiency is higher.Type: ApplicationFiled: March 19, 2021Publication date: July 8, 2021Inventors: Li-Te KUO, Yushun WU, Kuni LEE

Publication number: 20210088745Abstract: A lens module is provided, which includes one or more first lenses arranged along an optical axis and one or more second lenses arranged along the optical axis. A radial size of the second lens is larger than that of the first lens. A circumferential surface of the second lens with a larger radial size is formed through enclosing by one or more sections of cylindrical surface and a connection surface connected to the cylindrical surface. Compared with setting the circumferential surface to a complete cylindrical surface, the connection surface is formed in a radial direction of the second lens by cutting off a part, so that a vertical distance from an optical axis of the second lens to the connection surface decreases, and an optical axis of the photographing module is closer to a side frame of a mobile terminal, thereby reducing a width of a non-display area.Type: ApplicationFiled: December 3, 2020Publication date: March 25, 2021Inventors: Can LI, Li-Te KUO
