Title:
AUTOFOCUS ANTI-SHAKE PERISCOPE MOTOR HAVING LASER ETCHING CONDUCTIVE CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2023/000487
Kind Code:
A1
Abstract:
An autofocus anti-shake periscope motor having a laser etching conductive circuit, comprising: a base (20), a frame (30) disposed on the base (20), a carrier (40) disposed in the base (20), and a housing (10) embedded in the base (20). A Y-axis driving assembly (100) is provided on the inner side face of the frame (30). The Y-axis driving assembly (100) comprises a first driving coil (51) fixed on one side face of the carrier (40), a second driving coil (53) fixed on the other side face of the carrier (40) and disposed opposite to the first driving coil (51), and a Hall chip (52) and a capacitor (54) which are fixed on the carrier (40) and located on the same side as the second driving coil (53). The first driving coil (51) and the second driving coil (53) are communicated by means of a laser etching conductive circuit (80), wherein the laser etching conductive circuit (80) is fixed on the carrier (40) by means of a laser etching process. Therefore, the overall integration level of the motor is high, centralized detection is facilitated, occurrences of technical vignetting are avoided, the requirement of a high-quality camera is met, and the difficulty of tooling and processing is reduced.
