Abstract

L'invention concerne une charnière matérielle à auto-amortissement, comprenant un bras de charnière et une coupelle de charnière. Le bras de charnière et la coupelle de charnière sont reliés de manière articulée au moyen d'une première tige de liaison et d'une seconde tige de liaison ; un ressort de torsion de réinitialisation est disposé au niveau de la position où la première tige de liaison et le bras de charnière sont reliés de manière articulée ; le ressort de torsion de réinitialisation entraîne toujours la coupelle de charnière à dévier vers le bras de charnière ; un manchon fixe est en outre monté de manière fixe dans le bras de charnière ; un trou de montage est formé sur une face d'extrémité du manchon fixe ; un cylindre d'amortissement est monté dans le trou de montage ; un manchon coulissant est en outre emmanché de manière coulissante sur le manchon fixe ; une plaque de pression pressée sur le cylindre d'amortissement est disposée sur l'extrémité arrière du manchon coulissant ; des plaques de liaison sont disposées des deux côtés du manchon coulissant ; les plaques de liaison font saillie hors des deux côtés du manchon coulissant ; des bras d'entraînement s'étendant vers le haut sont disposés des deux côtés de la seconde tige de liaison ; et les bras d'entraînement entrent en contact avec les plaques de liaison. L'effet bénéfique du présent modèle d'utilité est que : étant donné qu'un amortisseur miniature est emmanché dans le manchon fixe, la zone de réception de force de l'amortisseur miniature est augmentée, de telle sorte qu'une transmission de puissance entre l'amortisseur et la charnière est plus stable et efficace.
