Description

Get rid of car seat heating device of hotspot Technical Field The invention relates to an automobile seat heating process, in particular to an automobile seat heating device for removing hot spots. Background The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. The existing automobile seat is generally provided with a heating function, and the heating principle is that a seat heating module is used for controlling the current of a heating device and generating heat, so that the temperature of the seat is increased, and passengers feel warm and comfortable when riding in a low-temperature climate. The heating principle is to supply power to the heating layer through a corresponding circuit so as to convert electric energy into heat energy. However, in the existing seat, the outer skin is generally sewn by the wires, so that a quilting path is generated, when the quilting path passes through the heating layer, a perforation is generated on the heating layer, and a hot spot phenomenon is formed at the perforation position, so that the heating temperature at the corresponding position is increased, and therefore, the surface of the seat at the position of the risk path is relatively hot and the heating uniformity is relatively poor. In order to cope with the hot spot phenomenon, the existing treatment method generally adds an additional structure, which improves the assembly difficulty and has extremely high process requirements.
