Method for preparing aperture, aperture, camera module, and electronic device

An aperture, manufactured and formed based on a method for preparing an aperture, wherein a guide groove of the aperture is provided with at least two sub-arc segments, and a G3 continuity design is applied between two adjacent sub-arc segments of the at least two sub-arc segments;

• wherein the aperture comprises a housing, a rotor disposed in the housing, and a plurality of blades annularly distributed on the rotor, wherein a guide post is disposed on the rotor, and the method comprises:
• acquiring an aperture stop of the aperture, a rotor motion parameter of the aperture, a guide post position of the aperture, and a blade parameter of the aperture;
• determining a guide groove path based on at least one of the aperture stop, the rotor motion parameter, the guide post position, or the blade parameter;
• acquiring a preset tilt angle specification;
• and
• in a case where a path inclination angle between the guide groove path and the guide post position does not meet the preset tilt angle specification, segmenting the guide groove path to establish at least two sub-arc segments, and applying a G3 continuity design between two adjacent sub-arc segments of the at least two sub-arc segments.

An electronic device, comprising:

• at least one processor and
• a memory communicatively connected to the at least one processor;
• wherein the memory stores a computer program executable by the at least one processor, and the computer program is configured to, when executed by the at least one processor, cause the at least one processor to execute a method for preparing an aperture according to;
• wherein the aperture comprises a housing, a rotor disposed in the housing, and a plurality of blades annularly distributed on the rotor, wherein a guide post is disposed on the rotor, and the method comprises:
• acquiring an aperture stop of the aperture, a rotor motion parameter of the aperture, a guide post position of the aperture, and a blade parameter of the aperture;
• determining a guide groove path based on at least one of the aperture stop, the rotor motion parameter, the guide post position, or the blade parameter;
• acquiring a preset tilt angle specification;
• and
• in a case where a path inclination angle between the guide groove path and the guide post position does not meet the preset tilt angle specification, segmenting the guide groove path to establish at least two sub-arc segments, and applying a G3 continuity design between two adjacent sub-arc segments of the at least two sub-arc segments.
