The perambulator that three kinds of modes are walked
Technical field
The invention belongs to perambulator technical fields, and in particular to the perambulator that three kinds of modes are walked.
Background technique
With the continuous growth of infant, mobility and fangle constantly enhance the attraction of infant, to only
Perambulator with simple function feels dull, will generate be weary of to perambulator over time.Therefore, applicant has developed
A plurality of can enhance takes enjoyment and gathers horizontal feeding type and dynamic formula in the perambulator of one, and such as application No. is 200810062430.0
Chinese invention patent disclose dynamic formula and horizontal feeding type walking new baby carriage, such perambulator in use, carrying
Body can be put down away with the walking of perambulator, and the band of the rotation or motor that also can use rear-wheel acts wavy undulatory motion,
So that supporting body is made swing walking, feeling of infant's generation like as running gallop in the inner is sat, to adapt to infant
Active psychology, make to sit infant in the inner and feel fresh, joyful, stimulation, comfortable, enhance the enjoyment of seating, infant
Sitting is not minded.Infant is given because of it is only without the enjoyment that independently manipulates, and more infants are more likely to independently grasp
The walking of perambulator is controlled, the perambulator of multifunction will be becoming increasingly popular.
