Title: DAMPER, AND LAUNDRY MACHINE USING SAME
Abstract:
A damper, and laundry machine using same. The damper comprises a rotating shaft (3), a cam mechanism (4), a buffer mechanism (5), and a stroke amplification mechanism (6). The rotating shaft (3) rotates about an axial direction. The buffer mechanism (5) provides a buffering force. The cam mechanism (4) is connected to the rotating shaft (3), and converts rotation with respect to the rotating shaft (3) into a linear reciprocating motion. The stroke amplification mechanism (6) is connected to the cam mechanism (4) and the buffer mechanism (5), and transmits and amplifies a small stroke of the cam mechanism (4) to provide a large stroke of the buffer mechanism (5). The stroke amplification mechanism (6) comprises a lever (61), and a fulcrum (613) divides the lever into a short arm (612) and a long arm (611). An end of the lever on the long arm (611) is connected to the buffer mechanism (5), and the end of the lever on the short arm (612) is connected to the cam mechanism (4). By employing the stroke amplification mechanism (6) to convert a small movement of the rotating shaft (3) into a large movement of the buffer mechanism (5), the present invention provides a design in which a small-angled rotation of the rotating shaft (3) can accurately provide a sufficient damping force, thus improving product safety, and providing superior user experience.
