Title:
ELECTRIC MOTOR APPLIED TO SHUTTER MECHANISM, SHUTTER MECHANISM, CAMERA, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/123107
Kind Code:
A1
Abstract:
An electric motor (34) applied to a shutter mechanism (30), the electric motor comprising: a base (100), a rotary assembly (200) and a damping assembly (300). The rotary assembly (200) is rotatably arranged on the base (100) and has a startup state and an exposure operation state. The damping assembly (300) is arranged on at least one of the base (100) and the rotary assembly (200). When the rotary assembly (200) is in the startup state, the damping assembly (300) can provide rotation resistance to the rotary assembly (200). When the rotary assembly (200) is in the exposure operation state, the rotary assembly (200) drives a blade assembly (32) to rotate, and the rotation resistance of the rotary assembly (200) is reduced. The electric motor (34) is applied to the shutter mechanism (30) and can improve the shutter speed.
