Three-dimensionally vibration-preventing buffering mechanism
A three-dimensionally vibration-preventing buffering mechanism is proposed, which is designed for use in conjunction with a dynamic module for the purpose of buffering the three dimensional vibrations of the dynamic module during operation, and which is characterized by the use of a group of specially-designed chained elastic members, each being composed of at least three integrally-linked flexure hinges whose axes of concavity are oriented respectively in parallel with the three axes of a three-dimensional rectangular coordinate system, so that the vibrations of the dynamic module in all three dimensional directions can be respectively buffered by these flexure hinges to provide a three-dimensional vibration-preventing buffering effect.

a group of chained elastic members, each of which includes:
a first flexure hinge having a first end side and a second end side, wherein the first end side thereof is fixedly attached to the body of the dynamic module, and between the first end side and the second end side thereof is the first flexure hinge formed with a pair of concaved surfaces on opposite lateral sides, with the axis of concavity of the two concaved surfaces substantially oriented in parallel to a first axis in the three-dimensional rectangular coordinate system;
a second flexure hinge, which is substantially similar in structure as the first flexure hinge, having a first end side and a second end side, wherein the first end side thereof is fixedly linked to the second end side of the first flexure hinge, and between the first end side and the second end side thereof is the second flexure hinge formed with a pair of concaved surfaces on opposite lateral sides, with the axis of concavity of the two concaved surfaces thereof substantially oriented in parallel to a second axis in the three-dimensional rectangular coordinate system;
a third flexure hinge, which is substantially similar in structure as the first flexure hinge and the second flexure hinge, having a first end side and a second end side, wherein the first end side thereof is fixedly linked to the second end side of the second flexure hinge, and between the first end side and the second end side thereof is the third flexure hinge formed with a pair of concaved surfaces on opposite lateral sides, with the axis of concavity of the two concaved surfaces thereof substantially oriented in parallel to a third axis in the three-dimensional rectangular coordinate system; and
a group of locking mechanisms for securely locking the second end side of the third flexure hinge to a chassis.
