The overall motion control process of the crib:

the three sets of universal wheels 11 can drive the chassis 14 to move in 360 degrees without rotating, so as to drive the outer cover 16, the fixed bed body 3 and the movable bed body 1 to move synchronously, and can also drive the chassis 14 to rotate around the center without generating horizontal displacement, so as to drive the outer cover 16, the fixed bed body 3 and the movable bed body 1 to rotate in situ. The above two movements are combined, and the movement with any degree of freedom of the crib can be realized.

Three sets of universal wheels 11 realize three point location, through the distance between the diameter that increases chassis 14 and the universal wheel 11 to and through the focus of whole car design of shifting down, can guarantee that the crib keeps stable balance when normal use, but under extreme condition, when like older infant violently plays in the car, can further strengthen the stability of automobile body: the screw 13 rotates in the forward and reverse directions to drive the adsorption platform 9 to move up and down along the guide rail 15, the adsorption platform 9 is controlled to move down, the lower adsorption end of each vacuum chuck 10 penetrates through a fabrication hole of the base plate 14 to contact with the smooth ground, the micro vacuum pump 5 sucks air to enable the vacuum chucks 10 to be firmly adsorbed on the ground, the screw 13 and the guide rail 15 transmit adsorption force to the outer cover body 16, and stability of the vehicle body at a fixed position is enhanced. On the contrary, the micro vacuum pump 5 is deflated, the adsorption platform 9 moves upwards to drive the vacuum suction cup 10 to be separated from the ground, and the crib continues to move in a controlled manner.

The control process of the movable bed body and the gentle fluctuation motion:

the micro air pump 7 controls the air bag cushion 2 to expand and contract through blowing and discharging, and then drives the movable bed body 1 to move up and down, and if a plurality of combined air bag cushions 2 are adopted, the bed body 1 can also generate a wave type movement effect. The pressure spring 4 plays the effect of reinforcing the motion stability of fluctuation, if gasbag pad 2 undulates motion range too big occasionally, pressure spring 4 can play the effect of reducing the frequency of amplitude.
