the swing wheel (2108) is movably connected with the meshing wheel (8), one end of the driving rod (2107) is movably connected with the eccentric position of the swing wheel (2108), the other end of the driving rod is movably connected with the push block (2106), the push block (2106) is installed on the sliding rail (2105) and can move along the sliding rail (2105), the sliding rod (2101) is hinged with the rotating rod (2102) to form an X-shaped bracket mechanism, one end of the sliding rod (2101) is hinged with the push block (2106), the left connecting rod (2103) and the right connecting rod (2104) form a triangular mechanism and are hinged with the sliding rod (2101) and the rotating rod (2104), and the tail end of the right connecting rod (2104) is provided with a supporting foot (21041), so that when the motor (13) pushes the meshing wheel (8) to rotate, the push block (2106) can be pushed to slide on the sliding rail (2105), all the sliding rods (2101) are driven to synchronously deform all angle control frames (21), and the height of the supporting feet (21041) of all right connecting rods (2104) is synchronously changed, thereby controlling the inclination angle range of the foot board seat (11);
when the supporting feet (21041) of all the angle control frames (21) touch the bowl bottom (1601), the angle control frames (21) can control the foot plate seat (11) to be fixed relative to the driving bowl (16), and the foot plate seat (11) is driven to carry out passive dynamic training of a human body or can carry out active static balance training of the human body by controlling the driving bowl (16) to move;
when the supporting feet (21041) of all the angle control frames (21) are half-folded, the supporting feet (21041) have a certain distance relative to the bowl bottom (1601), the driving bowl (16) is fixed, the foot plate seat (11) is connected with the bowl bottom (1601) through the pressure spring (15), so that active dynamic training of a human body can be performed, and the inclination angle range of the foot plate seat (11) relative to the bowl bottom (1601) is continuously adjustable.
10. The active and passive switching clutch device for the dynamic balance training of claim 9, further comprising a proximity switch, wherein the proximity switch is fixed on the upper surface of the foot plate seat (11) and located beside the inevitable path of the push block (2106), two contacts with different distances are arranged on the push block (2106), and when the proximity contact is close enough to the proximity switch, the proximity switch is triggered to obtain the limit condition of the angle control frame (21), namely the angle control frame extends to the longest, so that the human body can perform the passive dynamic balance training; when the far-end contact is close enough to the proximity switch, the proximity switch is triggered to obtain the other limit condition of the angle control frame (21), namely the angle control frame is contracted to the shortest, so that the human body can perform active dynamic balance training, and the change range of the motion angle is the largest.
