NOVELTY - The utility model claims a backpack for outdoor use in winter, comprising a backpack, the back surface of the backpack is sewed with a backpack sponge layer, a heating structure is set between the backpack and the backpack sponge layer. In the utility model, the storage battery is located on the graphene heating sheet to provide electric energy by pressing the power switch on the side of the backpack, so that the graphene heating sheet emits heat, and the heat generated by the graphene sheet is transmitted to the back of the human body, so as to provide a certain amount of heat for human body in cold weather; at the same time, when the backpack is needed to be placed outdoors, the rotating plate is dug out from the inner cavity of the metal plate, and the rotating plate is rotated along the rotating shaft, until the clamping block is clamped in the clamping groove, limiting the rotating angle of the rotating plate, after the rotating plate is fully unfolded, forming the effect of the bracket, so that the backpack can be placed far away from the ground, avoiding dirtying the bottom of the backpack, and reversely rotating the rotating plate, until the magnet block on the rotating plate is absorbed with the inner cavity side wall of the metal plate, then realizing the containing of the rotating plate.
