Elevating platform mechanism

The utility model discloses create an elevating platform mechanism, with 3 configuration based on the RRR parallel mechanism, introduce series -parallel connection mechanism thought on this basis, through corresponding side chain increase motion coupling relation between looks adjacent level parallel mechanism, make looks adjacent level parallel mechanism will move and do all can and transmit stepby step through the coupled relationship of an interchain, the final multistage stack that realizes the motion, it is not enough to have solved parallel mechanism working space, what the driven loadof one -level mechanism led to the fact before the drive of back one -level mechanism became in the series -parallel connection mechanism is bulky, multistage series -parallel connection mechanism issubject to the difficult more difficult scheduling problem of working control that leads to of the positive and negative relieving sleepiness of kinematics. These innovation and creation not only working space obviously increas
