  • Patent number: 10871622
    Abstract: A suspension system of a single-axis optical actuator is provided, including an elastic suspension plate in the form of a frame having two opposite ends each extended, through a beveled edge and a bending section, to form a cantilever arm. The elastic suspension plate is provided with a magnetic device on one side thereof. The cantilever arms are supported on a reinforcement frame to carry an optical lens. When an electric current is supplied through a connector to the magnetic device of the actuator, a reciprocal attraction or repulsion force is generated and applied to one side of the elastic suspension plate so that the elastic suspension plate may function as an oscillation member with an imaginary axis line between the two bending sections of the frame body as an axis to carry the optical lens to generate fast and position-constrained oscillation at two sides.
    Type: Grant

  • Patent number: 10670948
    Abstract: A suspension system of a biaxial optical actuator is provided, including a circuit-carrying base and an oscillation member, which is provided, in a center thereof, with an optical lens. An elastic suspension plate is coupled to the oscillation member and has four corners each forming an elastic unit that projects outside the oscillation member. The elastic units collaborate with support posts to support the elastic suspension plate and the oscillation member at a location above the base. The oscillation member is provided, on each of four sides thereof, with a magnetic device. The four magnetic devices is sequentially activated to apply a magnetic force such that the oscillation member together with the optical lens carried thereon to rotate about two imaginary axes of the elastic suspension plate respectively defined between each pair of two opposite magnetic devices to thereby serve as a rotation axes of the oscillation member.

  • Publication number: 20180210191
    Abstract: A suspension system of an optical actuator is arranged such that an oscillation member of an actuator is mounted, in a movable manner, on a base, and the base comprises an assembly opening formed in a central portion thereof, the assembly opening being provided with a positioning seat on each of at least one diagonal bisection line. The oscillation member that comprises an optical lens is supported on the base by two flexible members so as to form a suspension system of an optical actuator. The two flexible members are each a plate-like structure and has two opposite side edges each formed with a shaped trough with a portion therebetween forming a bridge, and two sides of the bridge are corresponding to tangential lines of positioning curves of the shaped troughs.
