(CN212678408-U) NOVELTY - in the using process of the bottom trousers often needs to face the stretching, bending and so on; the heating main body of the heating component in the traditional electric heating clothes such as carbon fibre, electric heating wire and graphene and the lead do not have elasticity, easy to stretch the clothes; bending and so on, so as to not simply apply the heating assembly in the traditional electric heating clothes to the bottom of trousers. The utility model claims a bottom trousers, comprising two layers of elastic cloth and a heating component between the two layers of elastic cloth; the heating component comprises an elastic heating cloth, a switch for controlling the operation of the elastic heating cloth and a lead connected with the elastic heating cloth and the switch, wherein the elastic heating cloth has conductive and heating function; The elastic heating cloth can be used as the heating main body and bear most of the function of the lead, so the heating component can resist stretching in the process of using the bottom trousers, bending and so on without open circuit; it can ensure long-term stable use of the bottom trousers. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the bottom-punching trousers. Heating area (10) Heating component (20) Elastic heating cloth (21) Switch (22) Elastic cloth (30)
