Problems solved by technology

[0004] However, the existing inter-mirror shutters generally have disadvantages such as complex structure, large volume, and heavy weight.
[0005] Moreover, in recent years, the size of the camera module has been gradually reduced with the development of technology, but the size of the shutter driving device has always been a major obstacle restricting the miniaturization of the size of the camera module.

Abstract

A motor (10), which is applied to a shutter device (1) and an imaging device with the shutter device (1), and includes a printed circuit board assembly (12) with a winding (120), a stator core (13), A rotor (14) and a magnet (15) mounted on the rotor (14). The printed circuit board assembly (12) has a first side (121) and a second side (122). The stator core (13) is installed on the first side (121) of the printed circuit board assembly (12), and the winding (120) is arranged around the stator core (13). The rotor (14) and the magnet (15) are mounted on the second side (122) of the printed circuit board assembly (12) and spaced apart from the winding (120). The motor (10) has a flat structure, thereby facilitating the miniaturization of the shutter device (1).

Description

technical field [0001] Embodiments of the present invention relate to the technical field of imaging equipment, and in particular to a motor applied to a shutter device, a shutter device and an imaging device. Background technique [0002] Camera shutters usually include focal plane shutters and inter-lens shutters. A focal plane shutter is a shutter placed in front of the focal plane of imaging, usually referred to as a rolling shutter. The power released by the front curtain and the rear curtain comes from the spring and the connecting rod assembly. A deceleration motor winds the front and rear curtains at the same time through the spring and the connecting rod assembly. The front and rear curtains are each powered by an electromagnet. Separate control to realize the timing action of the front curtain and the rear curtain. The focal plane shutter is mainly used on SLR cameras. [0003] The inter-lens shutter is a shutter placed at the internal aperture of the lens, also...
