Abstract

Provided are a blade driving device, a camera device and a portable electronic device. The blade driving device includes a housing, a rotary body, a blade, at least one driving coil, a circuit board and at least one magnetic yoke. At least one rotating shaft extending into the accommodation space is disposed on the housing. The rotary body is a magnetic member with at least two magnetic poles. The blade includes one end fixedly connected to the rotary body and rotatable with the rotary body, and another end provided with a shielding portion and an opening portion. Compared with the related art, the present disclosure achieves compactness by omitting a number of mounted parts, realizing high efficient utilization of space and simplicity of structure and assembly, and enabling more efficient blade driving with a simpler structure.

Dependent claims

A blade driving device, comprising:

a housing, including a base and a cover plate, wherein the base has a first through-hole, the cover plate has a second through-hole, the first through-hole and the second through-hole form an optical axis channel, the base and the cover plate form an accommodation space, and the housing is provided with at least one rotating shaft extending into the accommodation space;
a rotary body, being a magnetic member with at least two magnetic poles, provided with a pivot hole sleeved on a respective rotating shaft of the at least one rotating shaft, and rotatable relative to the respective rotating shaft;
a blade, having one end fixedly connected to the rotary body and rotatable with the rotary body, and another end provided with a shielding portion and an opening portion, wherein the shielding portion is formed in a circumferential direction of the opening portion, and the optical axis channel is located in a moving path of the opening portion;
at least one driving coil, wherein an orthographic projection of the rotary body in a direction of the optical axis channel has an overlapping area with the at least one driving coil;
a circuit board, electrically connected to the at least one driving coil;
and
at least one magnetic yoke, fixed to the housing.
