The invention provides a rotating mechanism, an armrest device and a vehicle, and belongs to the technical field of vehicle armrest structures. The rotating mechanism comprises a rotating shaft; the rotating shaft is rotatably sleeved with the transmission wheel, the transmission wheel is provided with a first end face and a second end face which are opposite in the axial direction of the rotating shaft, and the first end face is provided with protruding limiting teeth; the first limiting piece is fixed to one end of the rotating shaft and used for blocking the second end face; the rotating shaft is sleeved with the locking wheel, the locking wheel and the rotating shaft form anti-rotation connection, the locking wheel locks a third end face and a fourth end face, opposite to each other in the axial direction of the rotating shaft, of the locking wheel, the third end face is opposite to the first end face, a limiting groove is formed in the third end face, and the limiting groove comprises a first concave part, a first boss, a second concave part and a second boss which are sequentially arranged; the second limiting piece is fixed to the end, away from the first limiting piece, of the rotating shaft; and the pressure spring is propped between the fourth end surface and the second limiting piece and is used for promoting the limiting groove to be meshed with the limiting teeth. The rotating mechanism is simple in structure and low in cost.
本发明提供了一种转动机构、扶手装置及车辆,属于车辆扶手结构技术领域。该转动机构包括:转轴;传动轮,可转动地套设于转轴处,传动轮具有在转轴的轴向上相对的第一端面和第二端面,第一端面设有凸起的限位齿;第一限位件,固定于转轴的一端,用于阻挡第二端面;锁止轮,套设于转轴处且与转轴形成防转动连接,锁止轮锁止轮在转轴的轴向上相对的第三端面和第四端面,第三端面与第一端面相对且第三端面处设有限位槽,限位槽包括依次设置的第一凹部、第一凸台、第二凹部和第二凸台;第二限位件,固定于转轴远离第一限位件的一端;以及压簧,抵接于第四端面和第二限位件之间,用于促使限位槽和限位齿啮合。本发明的转动机构结构简单且成本较低。
