The invention relates to a fixed shaft rotation adjusting mechanism which comprises a rotating shaft, a shell, a damping device and a motor, the damping device is arranged between the rotating shaft and the shell in the axial direction, and the shell used for supporting the rotating shaft is fixedly connected with an outer shell of the motor. An output shaft of the motor is connected with the rotating shaft so as to drive the rotating shaft to rotate around the fixed shaft through torque output of the motor, the rotating shaft is provided with a rotating shaft damping matching face, and the shell is provided with a shell inner hole. The damping device provides frictional resistance between the inner hole of the shell and the damping matching face of the rotating shaft so as to provide damping needed in the circumferential direction when the rotating shaft rotates in the shell, and meanwhile axial movement of the rotating shaft is limited. According to the fixed shaft rotation adjusting mechanism, the number of parts is small, the mechanism complexity is small, rotation around the fixed shaft can be achieved, any swing angle can be achieved, more comfortable watching experience of passengers on a vehicle is achieved, and the fixed shaft rotation adjusting mechanism has wide application prospects.

    本发明涉及一种定轴旋转调节机构,其包括转动轴、壳体、阻尼装置和电机,其中,阻尼装置在转动轴和壳体之间轴向方向布置,用于支撑转动轴的壳体与电机的外壳固连,电机的输出轴与转动轴连接以通过电机的扭矩输出驱动转动轴围绕着定轴旋转,转动轴具有转动轴阻尼配合面,壳体具有壳体内孔,阻尼装置在壳体内孔和转动轴阻尼配合面之间提供摩擦阻力以提供转动轴在壳体内转动时周向方向所需的阻尼,同时限制转动轴在轴向发生窜动。根据本发明的定轴旋转调节机构,零件数量少,机构复杂度小,且可实现绕定轴转动具有任意摆角,实现车载乘客更舒适的观看体验,具有广阔的应用前景。
