The invention discloses a manual rotation damping mechanism which comprises a base, an assembly hole is formed in the base, a main shaft is arranged in the assembly hole, the axial direction of the main shaft extends in the vertical direction, and the main shaft is rotationally matched with the assembly hole; the main shaft is sleeved with a plurality of static damping fins and a plurality of dynamic damping fins, the static damping fins and the dynamic damping fins are sequentially and alternately distributed in the axial direction of the main shaft, the static damping fins are connected with the side wall of the assembly hole, and the dynamic damping fins are connected with the side wall of the main shaft. The static damping fin is in damping fit with the dynamic damping fin; when the main shaft drives the dynamic damping fin to rotate relative to the assembly hole, the static damping fin does not rotate relative to the assembly hole, so that damping force is generated between the dynamic damping fin and the static damping fin. The device is reasonable in structural design, and the position of the vehicle-mounted display screen can be manually adjusted and rotated.
本发明公开了一种手动旋转阻尼机构,包括底座,所述底座上设有装配孔,所述装配孔中设有主轴,所述主轴的轴向沿竖向延伸,所述主轴与所述装配孔转动配合;所述主轴上套有若干个静阻尼片以及若干个动阻尼片,若干个所述静阻尼片与若干个所述动阻尼片沿所述主轴的轴向依次交替分布,若干个所述静阻尼片与所述装配孔的侧壁连接,若干个所述动阻尼片与所述主轴的侧壁连接,所述静阻尼片与所述动阻尼片阻尼配合;在所述主轴带动所述动阻尼片相对所述装配孔转动时,所述静阻尼片相对所述装配孔不发生转动,以使所述动阻尼片与所述静阻尼片之间产生阻尼力。本发明的结构设计合理,可以通过手动调整旋转车载显示屏位置。
