Title:
DAMPER, AND LAUNDRY MACHINE USING SAME
Document Type and Number:
WIPO Patent Application WO/2018/121721
Kind Code:
A1
Abstract:
A damper, and laundry machine using same. The damper comprises: a rotating pin (5), a slider crank mechanism (2), a buffer mechanism (3), and a stroke amplification mechanism (4). The rotating pin (5) rotates about an axial direction. The buffer mechanism (3) provides a buffering force. The slider crank mechanism (2) is connected to the rotating pin (5), and converts rotation of the rotating pin (5) into a linear reciprocating motion. The stroke amplification mechanism (4) is connected to the slider crank mechanism (2) and the buffer mechanism (3), and transmits and amplifies a small stroke of the slider crank mechanism (2) to provide a large stroke of the buffer mechanism (3). By employing the stroke amplification mechanism to convert a small movement of the rotating shaft (5) into a large movement of the buffer mechanism (3), the above technical solution provides a design in which a small-angled rotation of the rotating shaft can accurately provide a sufficient damping force, thus improving product safety, and providing superior user experience.
