AUTOMATICALLY RESTORABLE BRACE DAMPER DEVICE AND DAMPER DEVICE USING AUTOMATICALLY RESTORABLE AND SELF-HEALABLE SMART MATERIAL

Document Type and Number:

WIPO Patent Application WO/2019/031669

Kind Code:

A1

Abstract:

A damper device of the present invention comprises: a guide unit having a predetermined length along an imaginary load applying line that is parallel to the direction in which tensile force or compressive force is applied; a first movable unit coupled to one side of the guide unit and capable of reciprocating in parallel to the load applying line; a second movable unit spaced apart from the first movable unit, coupled to one side of the guide unit and capable of reciprocating in parallel to the load applying line; a deformation unit connecting the first movable unit and the second movable unit, and formed so as to be tensioned and restored along the direction parallel to the load applying line; and an operating unit formed so as to enable the second movable unit to be pulled such that the second movable unit moves away from the first movable unit and to enable the first movable unit to be pushed such that the first movable unit moves away from the second movable unit, wherein the deformation unit becomes tensioned when the operating unit pulls the second movable unit or pushes the first movable unit. According to the present invention, the deformation unit is formed so as to become tensioned when the tensile force is applied to both ends of the damper device and the compressive force is applied thereto, such that the deformation of the deformation unit is easily predicted, thereby facilitating the design of the damper device for absorbing shock and controlling vibration and displacement, and enabling the damper device having a stable structure to be provided.
