Document Type and Number:
WIPO Patent Application WO/2023/000486
Kind Code:
A1
Abstract:
A three-axis auto-focusing and anti-shake periscope motor, comprising: a base (20), a frame (30) provided on the base, a carrier (40) provided inside the base, and a housing (10) fitted with the base. A Z-axis closed-loop circuit component is attached to a Z-axis driving component (60), and a Y-axis closed-loop circuit component (80) is attached to the carrier. The Z-axis closed-loop circuit component comprises a Z-axis circuit board, and a Z-axis Hall chip and an X-axis Hall chip provided on the Z-axis circuit board. The Y-axis closed-loop circuit component comprises a Y-axis circuit board and a Y-axis Hall chip provided on the Y-axis circuit board. The motor has a high overall integration level, which facilitates centralized detection, avoids technical vignetting, meets the requirement of a high-quality camera, and meanwhile, the difficulty of tooling and processing is reduced, and the costs are reduced.
