This design is mainly aimed at the problem of lack of mother and infant room in outdoor scenes. An innovative design scheme is proposed. Combined with the current technology and practical low-speed unmanned vehicle, a shared intelligent mother and infant vehicle is designed. The interior meets the various needs of the baby-carrying person. Users can nurse and change diapers in the mother and infant vehicle, and can also rest and relax inside. At the same time, this design also solves the travel problem of baby carriers and can be used as a means of transport. Through big data, city managers can more accurately manage the smart mother-to-child vehicles in the city and arrange more mother-to-child vehicles in areas with more baby carriers. This design reflects the care of maternal and child groups, is conducive to enhance the level of civilization of the entire city.
