The invention relates to a tent type automatic-temperature-regulating quilt, in particular to sleep automatic temperature regulating. The tent type automatic-temperature-regulating quilt comprises a ceiling outer cover, ceiling supports, a ceiling lining, a base support, a bottom cushion and heat-discharge skylights, wherein the bottom cushion is tied to the bottom support through tying ribbons and the like, the ceiling supports are fixed to the base guide rails of the base support through support column fixing rings, at the lower ends of ceiling support columns, and the like, the ceiling lining is tied to the inner sides of the ceiling supports through tying ribbons and the like, the ceiling outer cover is fixed through ceiling support fixing pins and the like and covers the ceiling supports, and each heat-discharge skylight is mounted at the corresponding opening of the ceiling outer cover through hook and loop fasteners and the like. When the temperature in the quilt rises to a certain value, the heat-discharge skylights are opened to discharge hot air in the quilt so as to fast lower the temperature in the quilt, the heat-discharge skylights are closed when the temperature in the quilt lowers to a certain value, the temperature in the quilt is kept and then rises, and accordingly the temperature in the quilt can be kept at a value which a person feels comfortable, and a sleep automatic temperature regulating function is achieved. The tent type automatic-temperature-regulating quilt also has a quilt kicking preventing function and a suffocation preventing function.
