▎ 摘　　要

NOVELTY - Handlebar heating device, comprises a support portion (1) and a heating portion (2). The support portion is installed on the handlebar, and the heating portion at least includes a windshield shell (3) and a graphene heating film (4) provided on the windshield shell. The graphene heating film is composed of a flexible polyimide copper-containing material, graphene conductive heating ink, and polyethylene terephthalate waterproof protective film laminated in sequence. The flexible polyimide copper-containing material is connected to the windshield. The conductive heating ink consists of 4-15 wt.% water-based acrylic resin, 4-12 wt.% graphene powder, 5-15 wt.% dispersant, 0.5-1 wt.% defoamer, 35-50 wt.% deionized water, and 5-10 wt.% slow drying agent. The supporting portion and the heating portion is folded and unfolded, and the distance between the graphene heating film and the handlebar when the supporting portion and the heating portion are unfolded is 10-20 cm. USE - Handlebar heating device, such as motorcycle and electric vehicle handlebars. ADVANTAGE - The device can be unfolded in front of the hand to form a special semi-enclosed curved surface structure when riding in winter, is waterproof and capable of collecting heat, reach a heating effect of 40-50 degrees C at a distance of 10-20 cm, can ensure the user hand with enough movable space, and reach the ideal temperature effect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for manufacturing handlebar heating device according to the size of the windshield, which involves making the copper-containing polyimide copper-containing material of the corresponding size, with a thickness of 0.05-0.15 mm, etching the circuit on the copper-containing polyimide copper-containing material, printing graphene conductive heating ink on the line and drying it, after drying and curing, pressure-bond the polyethylene terephthalate waterproof protective film, installing the power cord and temperature adjustment switch, and make it insulated and waterproof, carrying out running test, where surface temperature of graphene heating film is 55-60 degrees C which is qualified, installing the qualified graphene heating film on the windshield shell, and assembling the support portion and the heating portion into a handlebar heating device, and installing the handlebar heating device on the handlebar. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a handlebar heating device. Support portion (1) Heating portion (2) Windshield shell (3) Graphene heating film (4)
