Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile seat cushions, in particular to a heating type automobile seat cushion. BACKGROUND

[0002] With the continuous improvement of living standards, in order to improve the comfort of automobile seats, many automobile seats currently have heating functions. Based on performance and health concepts, many graphene heating pads have appeared, but the traditional graphene heating pad has the following shortcomings:

[0003] A: Printed graphene heating pad: using graphene paste, screen printing graphene heating layer and silver paste electrode layer on PET or PI film, and leading out the wire; it has the following defects: 1. The graphene heating layer is printed, and the uniformity of the resistance is poor, resulting in uneven heating; 2. Long-term use, due to mechanical action, the graphene layer cracks, the resistance rises, and the power decays; 3. Silver paste electrode needs to carry large current, so the width of silver paste line needs to be increased, which reduces the area of the heating area and increases the material cost. The existence of silver paste resistance leads to increased tail resistance and increased voltage drop, and the heating temperature decreases; 4. Since the silver paste is in the form of printing, there is a phenomenon of heating and attenuation at the wire outlet; 5. The heating pad is stressed at the rib, and long-term mechanical friction causes the silver paste wire to break; 6. High waste rate, complex process, and high cost;

[0004] B: PU film graphene heating pad: using a planar PU film, a rectangular structure, arranging conductive copper foil on both sides, pasting a protective layer, and then leading out the wire; it has the following defects: 1. Since it is a planar structure, and the electrodes are arranged in parallel, the heating shape can only be regular, and cannot completely match the structure on the seat; 2. The electrode is a conductive copper strip, and the contact surface between the conductive adhesive and the graphene has contact resistance, which generates heat, and the conductive adhesive hardens and decays after long-term use, eventually leading to contact failure; 3. After pasting the conductive copper strip, in order to facilitate the wire outlet, the electrode strip needs to be close, so the copper strip needs to be bent and then connected, which often causes problems; 4. The conductive copper strip has poor wear resistance; 5. The conductive copper strip has high cost;

[0005] C: Laminated graphene heating pad: using graphene powder, adding adhesive, and laminating to form a graphene heating body, pasting a protective layer, and then leading out the wire; it has the following defects: 1. High cost; 2. Poor resistance uniformity; 3. Long-term use, due to mechanical action, the graphene layers are separated, the resistance rises, and the power decays; 4. The heating pad is stressed at the rib, and long-term mechanical friction causes the graphene wire to break.

[0006] In view of the above, the graphene material film forming process is complex, the production cost is high, the pure graphene structure mechanical property is poor, the service life is short, and it has not been fully verified by the market, so many main machine factories dare not use the above graphene heating pad, and at present, it is urgent to design a graphene heating pad with stable performance, low material cost, simple process and high production efficiency.

[0035] Specifically, the graphene fabric layer 4 includes a nonwoven fabric 8, on which a graphene slurry coating is fixedly disposed. Preferably, the graphene fabric layer 4 is solidified on the nonwoven fabric 8 using processes such as coating, printing, or spraying. The graphene slurry coating has a square overall shape and is arranged in an array on the nonwoven fabric 8.
