Abstract

La présente invention concerne un ensemble pivotant d'ouverture et de fermeture automatique à fonctions manuelles. Son élément d'entraînement comporte un micromoteur de type à cloche et une boîte à engrenages planétaires, et la sortie du micromoteur est directement raccordée à l'entrée de ladite boîte à engrenages planétaires. L'ensemble comporte également un bras mobile et un mécanisme de couplage à friction. L'arbre de sortie de la boîte à engrenages planétaires est raccordé au mécanisme de couplage à friction. Une extrémité du bras mobile est raccordée au mécanisme de couplage à friction et l'autre extrémité est raccordée au support mobile. La structure de l'ensemble est simple, et elle peut non seulement être ouverte et fermée automatiquement par des touches, mais également manuellement par le mécanisme de couplage à friction ; de plus elle ne détruira pas le micromoteur et la boîte à engrenages. Elle peut être utilisée pour des blocs-notes, des caméras numériques, des éléments de liaison pour écrans et corps de DVD portables, et des éléments de liaison pour antennes télescopiques et rotatives et bases de GPS.
