In view of the low coverage and poor accessibility of the mother and baby room in the current outdoor scene, the work aims to provide a feasible design solution for the outdoor intelligent mobile mother and baby car, and create a comfortable and high-quality outdoor childcare space for those going out with babies. Through field research, the configuration and use status of existing indoor and outdoor mother and baby rooms was observed and analyzed. Through user research, the use needs of mother and baby rooms in outdoor scenes of baby-carrying groups were explored. Then, the advantages of existing products were learned through typical case analysis. Finally, a systematic design solution of outdoor intelligent mobile mother and baby cars was proposed and detailed design was carried out. The mobile mother and baby cars not only had the basic functions of breastfeeding and diaper changing, and also provided intelligent functions such as being on call through mobile phone, being able to make an appointment, being able to view the status and location, controlling the environmental conditions in the car, and purchasing emergency supplies for mothers and babies, providing reference for the design and research of mother and baby rooms in the future. By combining driverless technology with the concept of mobile mother and baby rooms, a comfortable and high-quality outdoor childcare space is created for those going out with babies, improving the overall quality of urban mother and baby facilities construction and helping the construction of civilized cities.
