Description
Technical Field
The utility model relates to the field of heating films, in particular to a heating film for an automobile seat.
Background
The automobile seat heating utilizes an electric heating wire in the seat to heat the interior of the seat, and heat is transferred to passengers through heat transfer, so that the riding discomfort caused by the fact that the seat is too cold after being parked for a long time in winter is improved.
The basic structure of a conventional heating film for an automobile seat is as follows: the lower layer is a layer of non-woven fabric, the heating wires are arranged on the non-woven fabric, the heating wires are fixed on the non-woven fabric by using a fixing adhesive tape, the knitted fabric covers the fixing adhesive tape, is sewn into a shape similar to the heating position of the seat by using knitting yarns, and is sewn in the seat cover.
However, the non-woven fabric has poor uniformity of heat conduction, resulting in non-uniform heat conduction of the conventional heating film, and thus local overheating or insufficient heat is likely to occur. In addition, the common non-woven fabric has poor high temperature resistance, no flame retardant property and potential safety hazard, and the cost of the flame retardant non-woven fabric is higher.
SUMMERY OF THE UTILITY MODEL
In order to solve the above problems, an aspect of the present invention provides a heating film for an automobile seat, including: go up heat conduction silica gel layer, go up PI rete, heating plate, PI rete and heat conduction silica gel layer down, be provided with the gum layer between heat conduction silica gel layer and the last PI rete, also be provided with the gum layer down between PI rete and the heat conduction silica gel layer down.
Further, the thickness of the upper heat-conducting silica gel layer and the thickness of the lower heat-conducting silica gel layer are both 0.25-0.35 mm.
Furthermore, the heat conductivity coefficients of the upper heat-conducting silica gel layer and the lower heat-conducting silica gel layer are both 2W/m.K.
Further, the thickness of the upper PI film layer and the thickness of the lower PI film layer are both 0.2-0.3 mm.
Further, the thickness of the heating plate is 0.04-0.06 mm.
Further, the heating sheet is formed of a copper foil material.
Further, the back glue layer is formed by 3M glue.
After the technical scheme is adopted, the utility model has the effects that:
1. the heating film is good in heat conduction uniformity, and can conduct heat to the whole automobile seat more uniformly, so that the condition of local overheating or insufficient heat is avoided.
2. The heating film has good high-temperature resistance and flame retardant property, and the use safety of the heating film can be improved.

Detailed Description
It is specifically noted that, in the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise; the meaning of "several" is at least one. All directional indicators (such as up, down, left, right, front, and rear … …) in the embodiment of the present invention are only used to explain the relative positional relationship between the components, the movement, and the like in a certain posture, and if the certain posture is changed, the directional indicator is changed accordingly.
The technical solution of the present invention is further described by the following examples:
the present invention provides a heating film for an automobile seat, as shown in fig. 1, the heating film sequentially comprising: go up heat conduction silica gel layer 1, go up PI rete 2, heating plate 3, PI rete 4 down and heat conduction silica gel layer 5 down, be provided with gum layer 6 between heat conduction silica gel layer 1 and the last PI rete 2, also be provided with gum layer 6 between PI rete 4 and the heat conduction silica gel layer 5 down.
Above-mentioned heating film during operation, heating plate 3 forms the electricity with the heating circuit of car and is connected for send the heat, go up PI rete 2 with supreme heat conduction silica gel layer 1 of heat conduction, lower PI rete 4 with heat conduction to heat conduction silica gel layer 5 down, go up heat conduction silica gel layer 1 and give off the heat to whole car seat with heat conduction silica gel layer 5 down, and gum layer 6 plays the adhesive effect.
Wherein, heat conduction silica gel's thermal conductivity is strong to the heat conduction homogeneity is good, can be more evenly with the heat conduction to whole car seat that heating plate 3 sent, avoid the condition of local overheat or heat not enough.
The PI film has strong impact resistance, can absorb impact force under the conditions of collision and the like of an automobile, shows good buffering performance and reduces the possibility of damage of the heating film. In addition, the PI film also has good high temperature resistance and flame retardant property, and the use safety of the heating film can be improved.
Specifically, the thickness of the upper heat-conducting silica gel layer 1 and the thickness of the lower heat-conducting silica gel layer 5 are both 0.25-0.35 mm. In the present embodiment, the thickness of the upper heat conductive silicone adhesive layer 1 and the thickness of the lower heat conductive silicone adhesive layer 5 are both 0.3 mm.
More specifically, the upper and lower heat conductive silica gel layers 1 and 5 each have a heat conductivity of 2W/m.K. The heat conductivity coefficient can meet the efficiency requirement of the heat conduction of the current automobile seat.
Specifically, the thickness of the upper PI film layer 2 and the thickness of the lower PI film layer 4 are both 0.2-0.3 mm. In this embodiment, the upper PI film layer 2 and the lower PI film layer 4 are both 0.25mm thick.
Specifically, the thickness of the heating sheet 3 is 0.04-0.06 mm. In this embodiment, the thickness of the heat patch is 0.05 mm.
More specifically, the heater chip 3 is formed of a copper foil material. The copper foil has good heat-conducting property and high heat-conducting efficiency.
