Description

Technical Field

[0001] This utility model relates to an interior heating product based on graphene, belonging to the technical field of automotive interior and seat peripherals. Background Technology

[0002] As people's demand for personalized automotive products continues to grow, the design and production of automobiles and their internal components are also showing diversified functional characteristics. As a component of an automobile product that comes into direct contact with the human body, car seats need to possess good safety, comfort, and environmental friendliness.

[0003] Graphene is a lightweight material with excellent functional characteristics, consisting of a honeycomb structure composed of hexagonal rings. It is a newly emerging material in recent years. Graphene possesses superior heating performance compared to resistance wires, playing a crucial role in the rapid and uniform transfer of heat in graphene heating pads. This results in better thermal uniformity, enabling graphene heating pads to meet the optimized design requirements of automotive seats.

[0004] Existing interior heating products involve taking an injection-molded frame, performing surface treatments (such as plasma treatment, flame treatment, and primer coating) to enhance surface polarity, and then spraying water-based adhesive / hot melt adhesive onto the frame surface before encapsulating it with a graphene heating pad. The entire product can be structurally divided into: a graphene heating pad layer, an adhesive layer, a polarity-enhancing frame surface layer, and a frame layer. This process is cumbersome, involves many layers, and results in a large overall product volume. This application improves upon existing technology by integrating the graphene heating pad with the plastic frame through injection molding. Structurally, it consists of only two layers: a graphene heating pad layer and a frame layer. Utility Model Content

[0005] This invention designs and develops an interior heating product based on graphene, integrating the skeleton layer onto the graphene heating pad to reduce the product thickness and improve its environmental performance.

[0006] The technical solution provided by this utility model is as follows:

[0007] An interior heating product based on graphene, comprising:

[0008] The graphene heating pad has a rectangular structure.

[0009] A framework layer is disposed on one or both sides of the graphene heating pad layer;

[0010] The skeleton layer and the graphene heating pad layer are integrated by injection molding.

[0011] Preferably, the graphene heating pad has a multi-layer structure.

[0012] Preferably, the graphene heating pad comprises: an encapsulation cloth layer, a PI film layer, a graphene layer, a conductive cloth layer, a graphene layer, a PI film layer, and an encapsulation cloth layer, with the conductive cloth layer as the central layer, and the other layers symmetrically arranged along the conductive cloth layer.

[0013] Preferably, the graphene heating pad has dimensions of 300mm × 200mm.

[0014] Preferably, the solid content of graphene in the graphene layer is 1%.

[0015] Preferably, the injection-molded layer is made of a polymer material.

[0016] The beneficial effects of this utility model are as follows: The graphene-based interior heating product provided by this utility model integrates the graphene heating pad and the plastic skeleton into one piece through injection molding to form a graphene interior heating product. Structurally, it only has two layers: the graphene heating pad layer and the skeleton layer, eliminating the need for the glue layer and the reinforcing polarity skeleton surface layer, making the overall structure lighter and thinner. At the same time, it can reduce processing steps and improve processing efficiency during processing. This product has high environmental performance and low odor. Attached Figure Description
