Abstract
An actuator mechanism for a body is disclosed. The actuator mechanism has at least one actuator produced from an electro-active polymer material that changes form due to electrical energy, thereby actuating the body The actuator mechanism also has at least two strengtheners allowing the actuator to change its form, each holding the actuator from a different side, and positioned oppositely on the body The actuator mechanism further has at least one retainer tip holding the actuator from at least one side thereof.
Claims14
An actuator mechanism (1) comprising:
- a body (2),
- at least one actuator (3) produced from an electro-active polymer material that changes form due to electrical energy, thereby actuating the body (2),
- at least two strengtheners (4) allowing the actuator (3) to change its form, each holding the actuator (3) from a different side, and positioned oppositely on the body (2),
- at least one retainer tip (5) holding the actuator (3) from at least one side thereof,
- at least one retainer (6), which is mounted to two opposite strengtheners (4), to which the retainer tips (5) enabling to hold the actuator (3) are detachably attached, and to which the actuator (3) is secured by being tightened with more than one retaining tips (5) at intervals,
- wherein the retainer (6) has a first position (I) such that when the actuator (3) is not energized, the actuator (3) is stretched via the retainer (6) by ensuring the side of the actuator (3) that is close to the retainer (6) is compatible with the geometry of the retainer (6) and
- wherein the retainer (6) has a second position (II) such that it enables limitation of the form change of the actuator (3) coming from the first position (I) when the actuator (3) is energized.
