Patent number: 11874521Abstract: Provided is a camera module, including: a shell; a lens assembly movable relative to the shell; a focusing and driving assembly; an image stabilization and driving assembly; and a supporting and guiding assembly for supporting the lens assembly and guide a movement of the lens assembly. The supporting and guiding assembly comprises a first magnetic portion fixed to the lens assembly, a second magnetic portion fixed to the shell and spaced from and opposite to the first magnetic portion, and a ball provided between the first magnetic portion and the second magnetic portion. The lens assembly is connected to the shell through the supporting and guiding assembly in a rollable way. According to the present invention, the ball is arranged between the first magnetic portion and the second magnetic portion to guide the lens assembly to achieve restoration, thereby saving an inner space and facilitating assembling thereof.Type: GrantFiled: July 29, 2020Date of Patent: January 16, 2024Assignee: AAC Optics Solutions Pte. Ltd.Inventors: Linzhen Li, Zhuming Chu, Tongming Xu, Houwei Zhao, Kai Chen

Patent number: 11803041Abstract: The invention provides a prism module and a folded lens. The prism module includes a housing having an accommodation cavity, a prism assembly, a rotation shaft for rotationally connecting the prism assembly and the housing, a driving assembly for driving the prism assembly to rotate around the rotation shaft and a restoring assembly for resetting the prism assembly. The restoring assembly includes a first magnet and a second magnet. The first magnet is fixed on the prism assembly, and the second magnet is fixed on the housing and is set opposite to the first magnet with distance. The prism module of the invention can realize the resetting of the prism assembly, with small space occupation and convenient for assembly.Type: GrantFiled: September 11, 2020Date of Patent: October 31, 2023Assignee: AAC Optics Solutions Pte. Ltd.Inventors: Linzhen Li, Zhuming Chu, Tongming Xu, Houwei Zhao, Kai Chen

Patent number: 11635630Abstract: The invention provides a camera lens module, which include a housing, a first bracket, a lens assembly, a focus driving assembly and a stabilization detection mechanism. The stabilization detection mechanism is provided on the lens assembly and the housing for driving the lens assembly to move in a direction perpendicular to the optical axis direction of the lens assembly. The focus driving assembly of the present invention drives the first bracket to drive the lens assembly to move along the optical axis of the lens assembly to realize its automatic focus adjustment. The stabilization detection mechanism drives the lens assembly to move in the direction perpendicular to the optical axis of the lens assembly to achieve its anti-shake compensation.Type: GrantFiled: September 11, 2020Date of Patent: April 25, 2023Assignee: AAC Optics Solutions Pte. Ltd.Inventors: Tongming Xu, Houwei Zhao

Patent number: 11372195Abstract: A lens module is provided. The lens module includes: a fixing frame; a lens assembly arranged in the fixing frame; an elastic suspending assembly connected between the fixing frame and the lens assembly to suspend the lens assembly within the fixing frame; a first magnet arranged on the lens assembly; a focusing coil arranged on the fixing frame and configured to cooperate with the first magnet to drive the lens assembly to move along an optical axis direction; a second magnet arranged on the lens assembly; and an anti-shake coil arranged on the fixing frame and configured to cooperate with the second magnet to drive the lens assembly to move along a second direction perpendicular to the optical axis to compensate for shaking of the lens assembly in a direction perpendicular to the optical axis. With the invention, the shaking of the lens assembly in the fixing frame is compensated.Type: GrantFiled: August 4, 2020Date of Patent: June 28, 2022Assignee: AAC Optics Solutions Pte. Ltd.Inventors: Tongming Xu, Houwei Zhao

Patent number: 11309780Abstract: The vibration motor provided by the present disclosure includes an elastic assembly having an elastic frame, a first elastic supporting member, and a second elastic supporting member. The first and second elastic supporting members connects to the housing by the elastic frame. By virtue of the bended structure of the elastic frame, the first and the second elastic supporting members are arranged interlaced along the vibration direction, which greatly reduces the height of the vibration motor.Type: GrantFiled: November 11, 2019Date of Patent: April 19, 2022Assignee: AAC Acoustic Technologies (Shenzhen) Co., Ltd.Inventors: Tongming Xu, Houwei Zhao
