Description

Technical Field

[0001] The utility model relates to the technical field of heating wires, and particularly relates to an adjustable heating wire for an automobile seat. Background Art

[0002] Existing high-grade automobiles are generally equipped with an automobile seat heating pad on the automobile seat, and an important part of the automobile seat heating pad is the heating wire for the automobile seat. The quality of the heating wire for the automobile seat directly affects the heating effect of the automobile seat.

[0003] For example, a high-efficiency heat-dissipating heating wire for an automobile seat with the publication number of CN204993914U includes a bulletproof wire (1) inside. It is characterized in that a flat wire (2) is wound around the outer surface of the bulletproof wire (1). The flat wire (2) is a heating alloy wire, and a sheath (3) is coated outside the flat wire (2). The flat wire (2) is in surface contact with the bulletproof wire (1), and the flat wire (2) is in surface contact with the sheath (3). The high-efficiency heat-dissipating heating wire for an automobile seat of the utility model has the advantages of high heat dissipation efficiency and long service life.

[0004] And a heat-bonding heating wire for an automobile seat with the publication number of CN216357372U, including a heating wire; a protection mechanism is arranged outside the heating wire; in the utility model, a connection mechanism is installed outside one end of the protection mechanism. Personnel open the outer shell and then pass the wiring end of the protection mechanism through the inside of the outer shell. When the personnel snap the outer shell, the wiring end of the protection mechanism can be fixed by the support plate clamping outside the protection mechanism. When the heating wire inside the protection mechanism is damaged, the personnel can expose the internal protection mechanism by opening the outer shell, which is convenient for the operation of the personnel. By arranging a protection mechanism outside the heating wire, the personnel place the heating wire on the top of the heat dissipation shell, and then snap the fireproof shell on the top of the heat dissipation shell. At the same time, a heat dissipation coating is applied inside the heat dissipation shell, and a fireproof material is applied inside the fireproof shell. The heat dissipation material does not affect the heat dissipation of the heating wire, and the fireproof material can prevent the heating wire from catching fire and burning the materials on the top.

[0005] The above technical solutions all have some problems in practical applications. For example, the density of the heating wire is fixed. When laying the heating wire at positions with different heat generation requirements, only the stacking method can be used to increase its heat generation, but the stacked heating wire will affect the comfort of the seat and is not conducive to use.

[0006] Therefore, it is very necessary to invent an adjustable heating wire for an automobile seat to solve the above problems. Summary of the Invention
