The invention relates to the technical field of sleep assistance, in particular to a swing mechanism and an
infant sleep aiding device comprising the same, the swing mechanism comprises a
moving frame and a storage rack rotatably mounted above the
moving frame, the swing mechanism further comprises a swing
assembly, the swing
assembly comprises an arc-shaped rod rotatably connected to the storage rack, and an adjusting
pipe is fixedly mounted above the
moving frame; the pacifying
assembly comprises a pacifying box arranged above the storage rack, a third
piston pipe is slidably installed in the pacifying box, a pacifying pad is arranged at the bottom end of a third
piston rod, and the pacifying pad performs reciprocating lifting movement or reciprocating annular sliding. Reciprocating swing of the storage rack is completed through reciprocating lifting of an arc-shaped rod, a first
piston rod can be pushed in the lifting process, the sleep degree of an infant is detected through a
decibel detector, a pacifying mode is selected according to different conditions, air pressure in a first piston
pipe is selected to be transmitted to different piston pipes, and the comfort degree of the infant is improved. The mode of touching or
flapping is selected, so that the
functional diversity of the sleep-aiding product is improved, and the sleep-aiding effect is improved.
