An actuator release mechanism includes: a longitudinal sleeve movable along an axis between a lock and release positions; drive means for causing the longitudinal sleeve to move along the axis; and bias means to bias the longitudinal sleeve to the lock position. The drive means includes: a rotary solenoid having a first direction of rotation and a second direction of rotation; a toggle member having a toggle shaft connected to and rotatable with the rotary solenoid, and a toggle head in engagement with the longitudinal sleeve by pins extending radially inwards from the longitudinal sleeve and a helical guide rail provided on a radially outer surface of the toggle head. The longitudinal sleeve is mounted around the toggle head, such that rotation of the solenoid causes rotation of the toggle member and the guide rails which causes the pin(s) to ride along the guide rail to rotate the sleeve.

The present disclosure provides a lens module and a mobile terminal. The lens module can include a lens component, a mounting bracket, a blade assembly movably connected to the mounting bracket, and a driving assembly connected to the blade assembly. The blade assembly is provided with at least two apertures, and the at least two apertures have different diameters. The lens component is mounted to the mounting bracket, and the blade assembly is configured to rotate and switch the apertures to correspond to the lens component under driving of the driving assembly, such that an axis of one of the apertures coincides with an optical axis of the lens component.

A rotary solenoid includes: a fixed body portion having a casing in which a pair of bearing portions and positioned on front and rear sides are provided; and a movable body portion having a rotation shaft rotatably supported by the pair of bearing portions. The fixed body portion includes: the casing formed of a magnetic material; and an air-cored coil of which the surface orthogonal to an axial direction of the rotation shaft is fixed to an inner surface of the casing. The movable body portion includes: a rotor yoke having one end fixed to the rotation shaft; and a magnet portion having a pair of magnets and fixed to an opposing surface positioned on the other end side of the rotor yoke serving as a surface opposing the air-cored coil and disposed along a rotation direction of the opposing surface.

A fluid path opening/closing device includes a spool in a through-hole provided in an inside of the spool, a coil wound around the through-hole with respect to the spool, a movable iron piece accommodated in the through-hole in a state of being rotatable around a rotation axis, a yoke including a first member and a second member extending from one end portion in an extending direction of the first member toward the movable iron piece, the second member having an attraction portion that is capable of attracting and rotating the movable iron piece according to an energized state of the coil, and a fluid path unit including an opening portion provided to be closer to the attraction portion that to the rotation axis and provided near the attraction portion.

An actuator has a first stator with four first poles, a second stator with four second poles aligned with the four first poles, a permanent magnet between the first stator and the second stator, four armatures positioned at terminal ends of the aligned four first poles and four second poles, and coils wrapped around the first stator and the second stator. A controller selectively applies current to the coils to migrate flux created by the permanent magnet through selective poles of the first stator and the second stator to selectively alter air gap sizes associated with the four armatures.

An actuating mechanism includes a main body, an electromagnetic device fixed to the main body, and a swinging rod swingably connected to the main body. A position of connection between the swinging rod and the main body is opposite to an iron core of the electromagnetic device, and an upper end of the swinging rod is opposite to and spaced apart from the electromagnetic device. A permanent magnet is disposed on the upper end of the swinging rod, and a magnetic pole direction of the permanent magnet and a magnetic pole direction of the electromagnetic device cross each other. Since the permanent magnet on the swinging rod is opposite to and spaced apart from the electromagnetic device, the swinging rod is not in contact with the electromagnetic device during working process. This avoids knocking of the swinging rod on other components, and therefore prevents noise, reduces wear.

A vibration actuator includes: a fixing body having N-fold (N is a natural number) of 2 of core pole parts and a coil wound around each of the core pole parts; a movable body having a magnet part disposed being separated from each of the core pole parts in an axial direction of each of the core pole parts, for each of the core pole parts; and an elastic support part that movably supports the movable body, in which the magnet part has a magnetic pole disposed on each of the core pole part sides and facing each of the core pole parts, and in which the movable body vibrates in a direction orthogonal to both directions including a direction in which the N-fold of 2 of the core pole parts are aligned and the axial direction of the coil by the energization of the coil.
