Abstract

L'invention concerne un amortisseur et une machine à laver le linge l'utilisant. L'amortisseur comprend un arbre rotatif (3), un mécanisme à came (4), un mécanisme tampon (5) et un mécanisme d'amplification de course (6). L'arbre rotatif (3) tourne autour d'une direction axiale. Le mécanisme tampon (5) produit une force d'amortissement. Le mécanisme à came (4) est relié à l'arbre rotatif (3) et convertit la rotation par rapport à l'arbre rotatif (3) en un mouvement de va-et-vient linéaire. Le mécanisme d'amplification de course (6) est relié au mécanisme à came (4) et au mécanisme tampon (5), et transmet et amplifie une petite course du mécanisme à came (4) en vue de produire une grande course du mécanisme tampon (5). Le mécanisme d'amplification de course (6) comprend un levier (61), et un point d'appui (613) divise le levier en un bras court (612) et un bras long (611). Une extrémité du levier sur le bras long (611) est reliée au mécanisme tampon (5), et l'extrémité du levier sur le bras court (612) est reliée au mécanisme à came (4). En employant le mécanisme d'amplification de course (6) pour convertir un petit mouvement de l'arbre rotatif (3) en un grand mouvement du mécanisme tampon (5), la présente invention réalise une conception dans laquelle une rotation d'un petit angle de l'arbre rotatif (3) peut produire avec précision une force d'amortissement suffisante, améliorant ainsi la sécurité du produit et offrant une expérience d'utilisateur supérieure.
