Patent number: 12354766Abstract: A large-tonnage disc-shaped suspension ceramic insulator includes a ceramic insulator body, and a metal pin and a metal cap coaxially assembled with the ceramic insulator body through adhesive material, assembly interfaces of the ceramic insulator body, the metal cap, and the metal pin are coated with a primer; the adhesive material includes an expansion agent; and the expansion agent is configured to make the adhesive material expand after hardening so as to create a prestress between the ceramic insulator body and the metal pin as well as the metal cap. The present disclosure achieves overall compressive prestress distribution of the ceramic insulator product, mitigating thermal stress caused by temperature changes and improving the tensile strength of the large-tonnage disc-shaped suspension ceramic insulator assembly. By treating the assembly interfaces with the primer, the present disclosure significantly improves the assembly strength of the ceramic insulator/metal assembly.Type: GrantFiled: January 12, 2025Date of Patent: July 8, 2025Assignees: CHAOHU UNIVERSITY, PINGXIANG BEST INSULATOR GROUP CO., LTDInventors: Xiaoyong Xu, Jiasheng Liu, Hui Wei, Fenping Chen, Lin Xu, Linmin Xu, Zhiying Zhou, Jianguo Deng, Minghua Liu

Patent number: 12155933Abstract: A zoom method and an apparatus to improve zoom accuracy of a camera module are disclosed. The zoom method includes: controlling, based on a target focal length, the lens to move in different subregions when the lens moves in an operation region, and determining position information of the lens based on a position detection relationship of a subregion in which the lens is currently located. The lens is controlled to move based on a position of the lens detected when the lens moves, so that the lens can more accurately stop at a position corresponding to the target focal length. This helps improve focusing accuracy of the camera module.Type: GrantFiled: January 27, 2023Date of Patent: November 26, 2024Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Xiaoyong Xu, Jia Hu, Lei Lu
