Motion platform, radiotherapy bed and medical equipment

The invention provides a motion platform. The motion platform comprises a moving plate, a bottom plate, a fulcrum mechanism and at least two driving mechanisms. The fulcrum mechanism and the driving mechanisms are arranged on the bottom plate, the bottom surface of the moving plate is at least provided with three non-collinear supporting points, and the fulcrum mechanism and each driving mechanism are located at one supporting point and connected with the moving plate; and when the driving mechanisms independently drive the corresponding supporting points to move, the moving plate inclines, and the fulcrum mechanism provides the rotational degree of freedom for the moving plate only in the inclination direction of the moving plate. The motion platform can achieve two rotational degrees of freedom. 本发明提供了一种运动平台，包括：移动板、底板、支点机构及至少两个驱动机构。所述支点机构和驱动机构设置于所述底板上，所述移动板的底面至少具有三个不共线的支撑点，所述支点机构及每个所述驱动机构分别位于一个所述支撑点并与所述移动板连接；所述驱动机构独立驱动其对应的所述支撑点移动时，所述移动板产生倾斜，所述支点机构仅在所述移动板的倾斜方向上为所述移动板提供旋转自由度。本发明的运动平台能够实现两个旋转自由度。
