Abstract

L'invention concerne une pièce de liaison et une charnière aveugle en forme de coupelle. La pièce de liaison est reliée de manière rotative entre une coupelle de charnière (1000) et un bras de charnière (2000) ; la pièce de liaison comprend : une première pièce de liaison (3100), une extrémité de celle-ci étant articulée à une partie d'extrémité dans le bras de charnière (2000) à l'opposé de la coupelle de charnière (1000), et l'autre extrémité de celle-ci étant articulée à une deuxième pièce de liaison (3200) ; une deuxième pièce de liaison (3200), qui est reliée entre la première pièce de liaison (3100) et la coupelle de charnière (1000) ; une troisième pièce de liaison (3300), qui a une forme courbée, dont une extrémité est articulée sur une partie d'extrémité dans le bras de charnière (2000) à proximité de la coupelle de charnière (1000), l'autre extrémité de celle-ci étant articulée à une quatrième pièce de liaison (3400), et la position de courbure de la troisième pièce de liaison (3300) étant articulée sur la deuxième pièce de liaison (3200) ; et une quatrième pièce de liaison (3400), qui est reliée entre la troisième pièce de liaison (3300) et la coupelle de charnière (1000). Un ensemble tampon (4000) est disposé à l'extérieur sur la deuxième pièce de liaison (3200) et est utilisé pour diminuer la vitesse de rotation de la troisième pièce de liaison (3300). Les angles d'ouverture et de fermeture d'une charnière aveugle en forme de coupelle sont augmentés, et un effet tampon de la charnière aveugle en forme de coupelle pendant l'ouverture et la fermeture est amélioré.
