An optical element driving mechanism is provided and includes a fixed assembly, a movable assembly and a first driving assembly. The movable assembly is movable relative to the fixed assembly. The first driving assembly is configured to drive the movable assembly to move relative to the fixed assembly. The optical element driving mechanism further includes a first opening, and an external light beam travels along a first axis to pass through the first opening.

Optical element driving mechanism

A driving mechanism for moving an optical unit is provided, including a variable aperture module and a Voice Coil Motor module. The variable aperture module has a bottom plate connected to a lens holder of the Voice Coil Motor module. Specifically, the variable aperture module and the Voice Coil Motor are received in the same housing, so as to enhance the structural strength of the driving mechanism.

Driving mechanism

A driving mechanism for moving an optical unit is provided, including a fixed part, a movable part, and a driving unit. The movable part is connected to the optical unit and the fixed part, and the movable part is movable relative to the fixed part. The driving unit is configured to drive the movable part and the optical unit to move relative to the fixed part.

A thin displacement driving device includes a first movable plate, a second movable plate, an axial limiting unit, a first actuator and a second actuator. The axial limiting unit limits the moving direction of the first movable plate and the second movable late. The first actuator has a first shape memory alloy wire coupled to the first movable plate, and the second actuator has a second shape memory alloy wire coupled to the second movable plate. Movement of the first movable plate by the actuation of the first actuator will trigger movement of the second movable plate, and movement of the second movable plate by actuation of the second actuator will trigger movement of the first movable plate.

Thin displacement driving device

The present invention provides a relay with a shape memory alloy (SMA) wire driven mechanism. Conventional mechanical relays rely on electromagnetic principle to operate. Hence, magnetic fields of electromagnetic relays often interfere with magnetic fields of other electrical components, thus resulting in the components physically interfering with each other. The present invention utilizes the shape memory characteristics of a SMA wire to achieve the purpose of changing the operation of the relay. Specifically, when a SMA wire is heated, it restores to its original shape or original length. Comparing to conventional mechanical relays, the relay provided by the present invention does not magnetically interfere with other electrical components, and thus is able to function effectively. In addition, because the relay of the present invention does not require iron cores or coils, available space therein is increased and may be used to accommodate control circuits with various functions.
