In some special extremely cold scenes, the heat preservation requirement cannot be met only by adding passive heat preservation, so that the dangers of frostbite, hypothermia and the like to the human body can be caused. Therefore, it is very important to introduce active heating, which can not only prevent the dissipation of heat to a certain extent, but also convert other forms of energy into heat energy through the corresponding active heat-insulating material, and generate heat effect by going round and transmitting to the human body. Therefore, compared with the traditional cold-proof clothes, the cold-proof clothes with the active heating function are lighter, thinner, more convenient and more effective. Meanwhile, the application scene of outdoor activities provides favorable conditions for the utilization of solar energy, the flexible thin-film solar cell can be tightly attached to the garment body, the collected light energy is converted into electric energy, and continuous energy supply is provided for heating materials in the garment.
In addition, the existing large amount of heating winter protection clothing in the market still confirms the output of heating power through the heating gear of user's manual selection, and the heating temperature range that different heating gears correspond is great, and the heating effect that corresponds often receives user state, outdoor environment's influence, leads to corresponding heating effect not necessarily to reach the expectation. Therefore, although there are few parts of heating clothes, the temperature of the heating part can be accurately regulated, the user often needs to manually try to regulate the temperature for many times, and when the activity state and the outdoor environment of the user change, the user needs to regulate the comfortable heating temperature again under the current condition.
