摘要： An SMA actuation apparatus comprises a camera lens element supported on a support structure by a plurality of flexures. An SMA wire at an acute angle to the movement axis and a biassing element are connected between the support structure and the movable element. A component of the force applied by the SMA wire perpendicular to the movement axis compresses the flexures causing them to apply a force to the movable element having a component along the movement axis in the same direction as the SMA wire. An end-stop limits the movement of the movable element, and the moment applied by the end-stop to the movable element about the centre of stiffness is equal to the moment applied by the SMA wire about the centre of stiffness at the point when the movable element loses contact with the end-stop on contraction of the SMA wire.

摘要： A shape memory alloy actuation apparatus comprises a movable element (6) suspended on a support structure (2) by a plurality of flexures (13) which are non- uniformly configured to apply forces having differing components perpendicular to the movement axis generating a net moment around the centre of mass of the movable element in an opposite sense from the moment generated by the actuation force. A shape memory alloy wire (31) is coupled between the support structure (2) and an intermediate body (25) engaging the movable element through a pivotal contact to avoid lateral force transfer. Also coupled between the support structure (2) and the intermediate body (25) is a resilient biassing flexure (23) plastically deformed in a partial region thereof. The shape memory alloy wire is crimped by a crimping member (32) fixed to the support structure holding the shape memory alloy wire against a curved surface (34) from which the shape alloy memory wire extends to the movabIe element.

摘要： An SMA actuation apparatus comprises a support structure, a movable element movably supported on the support structure and an arrangement of three or more SMA actuator wires mechanically connected between the support structure and the movable element. The SMA actuator wires have an interconnection at the movable element that electrically connects the group of SMA actuator wires together. This avoids the need to make a separate electrical connection to the movable element.

摘要： In a camera apparatus, two SMA actuator subsystems each comprise two SMA wires connected between a camera unit and a support structure, hooked over a pivot element defining pivot axes that lie in a common plane along the optical axis. Differential contraction of the SMA wires drives rotation. The SMA actuator subsystems are opposed, but the SMA wires of each subsystem are fixed respectively to the camera unit and the support structure, reducing the height. A non-conductive substrate supporting conductive tracks electrically connected to the SMA actuator system is configured as a flexure arrangement between the camera unit and the support structure. The flexure arrangement is connected to the camera unit at a position in the common plane reducing lateral resistance to tilt. Use of an intermediate connector element allows the circuit board to be arranged in front of the intermediate connector inside the height of the lens system.
