The invention provides an air outlet with a damping bushing. The air outlet comprises a support, a flexible bushing and at least one blade shaft. The flexible bushing is arranged on the bracket; at least one blade shaft penetrates through an inner hole of the flexible bushing and is in interference fit with the inner hole of the flexible bushing. The air outlet with the damping bushing provided bythe invention can be suitable for one, two or more than three of blade structures; the sensitivity of the soft bushing to the interference magnitude is far less than that of hard plastic, so that a mode of generating longitudinal force by interference fit of a soft bushing hole and a blade shaft is used instead of a mode of generating longitudinal force by interference fit of hard plastic shaft holes of the soft bushing hole and the blade shaft. The manufacturing precision of the mold and the injection molding process can be remarkably reduced, the mold modification frequency is reduced, meanwhile, the rotating hand feeling with the retardation feeling is obtained, and the damping bushing can be used as a standard part to achieve interchange.
本发明提供一种具有阻尼衬套的出风口,包括:支架、柔性衬套及至少一个叶片轴;柔性衬套设于支架上;至少其中一个叶片轴穿越柔性衬套内孔,两者采用过盈配合。本发明提供的具有阻尼衬套的出风口中可以适用于1根,2根或者3根以上的叶片结构;由于软性衬套对过盈量敏感度远小于硬塑料,用软性衬套孔和叶片轴的过盈配合产生纵向力的方式来代替往常两者均是硬塑料轴孔过盈配合产生纵向力,可显著减低模具和注塑工艺制造精度,减少模具修改次数,同时获得有阻滞感的转动手感,也利于将阻尼衬套作为标准件实现互换。
