[0115] Please refer to Figure 8 Specifically, the use of the same segment electrode folding is not limited to twice folding, nor is it limited to folding a right angle of 90 degrees. When folding once or folding at different angles, a segment of the conductive adhesive layer 11 is just away from the heat-generating body 4 after being folded once, and at this time, conductive adhesive can be additionally provided on the contact surface with the heat-generating body 4 to improve the flexibility of adaptation.

[0116] Specifically, the conductive adhesive tape can be integrally pasted on the conductive tape, or can be fixedly pasted on the conductive tape and the heating body or the first substrate or the second substrate.

[0117] In a preferred embodiment, the heating pad body comprises a plurality of groups of the heating assembly and a conductive assembly corresponding to the heating assembly.

[0118] Specifically, when a plurality of groups of the heating assembly are connected in parallel, the first electrode 1 and / or the second electrode 2 in each group of the heating assembly is independently provided, or can be shared. When shared, one of the heating assemblies near the outer side is a first heating assembly, and a plurality of second heating assemblies are sequentially distributed below the first heating assembly along the first direction. Each of the first electrode 1 and / or the second electrode 2 in the first heating assembly is extended towards the side close to the second heating assembly, so that each of the first electrode 1 and / or the second electrode 2 contacts the heat-generating body 4, and each group of the heat-generating body 4 along the first direction shares the same first electrode 1 and / or the second electrode 2.

[0119] In a preferred embodiment, the conductive assembly further comprises at least two wires 5, and the first electrode 1 and / or the second electrode 2 is connected to different wires 5 by welding.

[0120] Please refer to Figure 1 Specifically, one end of the first electrode 1 and the second electrode 2 is connected to each of the heat-generating bodies 4, and the other end is connected to different wires 5, respectively. The wire 5 is connected to a first plug 6 away from the side of the first electrode 1 and the second electrode 2, and the first plug 6 is used to connect a power supply element or other electrical components in the car, such as a controller.

[0121] In a preferred embodiment, at least one first through hole 13 is provided on the heating pad body, and the first through hole 13 is used to avoid connecting components.

[0122] Please refer to Figure 10 As shown, specifically, the first through hole 13 can be used as a breathable hole to assist the seat ventilation system to realize the flow exchange of air at the chair surface and other positions, and the connecting assembly is used for the fixation of the cover and the foam, such as buckles, barbed strips, or staples.

[0123] Specifically, each first through hole 13 can also be used as an unobstructed channel. For example, the automobile heating pad is arranged between the cover layer 8 and the foam layer 10 of the seat, the first connecting piece 12 is arranged on the cover layer 8, the foam layer 10 is provided with a second connecting piece 11, and the first connecting piece 12 and the second connecting piece 11 are fixedly connected by penetrating the first through hole 13. For example, the first connecting piece 12 and the second connecting piece 11 can be buckle structures that can be fixedly connected with each other, or can be barbed and adhered structures. For example, the first connecting piece 12 is a part of the fabric structure of the cover, and the second connecting piece 11 is a steel wire. At this time, a staple is needed to penetrate the first through hole 13 to connect the first connecting piece 12 and the second connecting piece 11, respectively.

[0124] In the prior art, since the heating pad body is arranged between the cover layer 8 and the foam layer 10, a first long slot needs to be formed on the heating pad body at the position where the cover layer 8 and the foam layer 10 are connected. The first long slot often reduces the heating area of the heating body 4, and the first electrode 1 and the second electrode 2 also need to be adapted to avoid the first long slot, which often disconnects the first electrode 1 and the second electrode 2 and independently sets them, thereby increasing the complexity of production. In the present patent, the first through hole 13 is formed on the heating assembly to avoid the first electrode 1 and / or the second electrode 2, and the area of the first through hole 13 is smaller than that of the first long slot. The first connecting piece 12 and the second connecting piece 11 are fixed by penetrating the first through hole 13, the heating pad body reduces the opening range, improves the heating area, and optimizes the electrode design function. Please refer to Figure 11 As shown, a plurality of first through holes 13 are arranged at the position of the groove 14 of the automobile seat, and the position of the first through hole 13 corresponds to the connection position of the first connecting piece 12 and the second connecting piece 11.
