[0017] The present invention will be described in more detail below with reference to the drawings and examples. The specific examples described herein are merely for the purpose of interpreting the relevant application, and are not intended to limit the application. For the sake of convenience, only parts related to the application are shown in the drawings.

[0018] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the accompanying drawings, in which: FIG.

[0019] Example 1 As described in the background art, the present invention provides a contoured heating structure for solving the problems in the prior art. The contoured heating structure is configured to heat a contoured interior trim in a vehicle. The contoured interior trim 1 includes at least one parallel region 11 and at least one contoured region 12 connected to the parallel region 11. The contoured heating structure includes two layers of a substrate 7 and a heating member. One of the layers, the substrate 7, covers the surface of the internal structure of the contoured interior trim 1. The heating member is installed between the two layers of the substrate 7. The heating member includes at least a heat generating portion 2 that actively generates heat and a heat transfer portion 3 that is in contact with the heat generating portion 2. The heat generating portion 2 corresponds to the position of the parallel region 11, and the heat transfer portion 3 corresponds to the position of the contoured region 12. The heat generating section 2 is configured to generate heat to heat the parallel region 11, and the heat is transferred to the heat transfer section 3 to heat the irregular region 12, thereby making the heating temperatures of the parallel region 11 and the irregular region 12 equal.

[0020] Specifically, the two layers of the substrate 7 are configured to protect the heating element installed inside. The substrate 7 may be made of woven fabric, or may be a sheet made of PET, PEN, PI, etc. The shapes of the two layers of the substrate 7 are the same as the shape of the surface structure of the irregular interior trim 1. The present invention provides an embodiment, in which, as shown in FIG. 1, in an interior armrest, the parallel region 11 is an elongated rectangle, the irregular region 12 is a right-angled trapezoid, and the irregular region 12 is located on one side of the parallel region 11 in the width direction. As shown in FIG. 2, the irregular heating structure according to this embodiment is installed in an interior armrest.

[0021] Furthermore, the parallel region 11 and the irregular-shaped region 12 have different areas. Therefore, in order to reach the same target temperature, the target heat supply amount supplied to each of the parallel region 11 and the irregular-shaped region 12 must be different.

[0022] Specifically, as shown in FIG. 3 and FIG. 4, the heat generating part 2 generates heat, and the generated heat can heat the parallel region 11 of the irregular-shaped interior trim 1. Here, the heating temperature required for the irregular-shaped interior trim 1 is understood to be the target temperature. By designing the power density of the heat generating part 2 and the heat transfer part 3, the heat generated by the heat generating part 2 in the parallel region 11 is greater than the first target heat supply amount required for the parallel region 11 to reach the target temperature, and at this time, the heat generated by the heat generating part 2 that is greater than the first target heat supply amount is constantly transferred from the heat generating part 2 to the heat transfer part 3. The heat transferred to the heat transfer part 3 is just the second target heat supply amount for heating the temperature of the irregular-shaped region 12 to the target temperature, and at this time, the temperature of the irregular-shaped region 12 can rise to the target temperature. Furthermore, since the parallel region 11 and the irregular region 12 have different areas, the first target heat supply amount and the second target heat supply amount must be different in order to reach the same target temperature. In this case, the difference between the first target heat supply amount and the second target heat supply amount is the difference between the heat generated by the heat generating portion 2 and the first target heat supply amount, that is, the second target heat supply amount.

[0023] In one alternative embodiment, the heating member includes a heat generating layer 9, and the heat generating layer 9 is provided at a position corresponding to at least the parallel region 11. The heat generating section 2 includes the heat generating layer 9 provided in the parallel region 11, and two electrodes 4 arranged in parallel on the heat generating layer 9.

[0024] This embodiment provides one embodiment of the heat generating part 2. That is, the heat generating part 2 is composed of at least the heat generating layer 9. The heat generating layer 9 is provided between two layers of the base material 7 and laid in at least the parallel region 11. Preferably, the heat generating layer 9 functions as a heat source and is laid in the parallel region 11 and the irregular region 12. The two electrodes 4 are parallel to each other and are provided at positions corresponding to the parallel region 11, and the two electrodes 4 are provided on the heat generating layer 9, and the heat generating layer 9 generates heat by energizing the two electrodes 4. The heat generating part 2 is composed of the two electrodes 4 and the heat generating layer 9 provided in the parallel region 11.

[0025] Moreover, the material of the heating layer 9 is graphene, carbon black or carbon nanotube. The power density of the material of the heating layer 9 in the parallel region 11 is the same.

[0026] Specifically, the heat generating layer 9 is composed of one or more of graphene, carbon black, carbon nanotubes, or other heat generating materials. The heat generating layer 9 may be a heating film made of graphene, carbon black, or carbon nanotube materials. When the substrate is a sheet made of a material such as PET, PEN, or PI, the heat generating layer 9 may be a film-like layer formed by printing graphene, carbon black, or carbon nanotube materials on the substrate 7. Since the width of the parallel region 11 is kept constant, the power density of the material of the heat generating layer 9 is the same at any position in the parallel region 11. This allows the heating temperature at each position in the parallel region 11 to be uniform.

[0027] Specifically, the electrodes 4 are installed only at positions corresponding to the parallel region 11. The electrodes 4 include a first electrode 41 and a second electrode 42, the first electrode 41 being the electrode 4 on the side away from the heat transfer section 3, and the second electrode 42 being the electrode 4 on the side close to the heat transfer section 3. The extension direction of the first electrode 41 and the second electrode 42 is the longitudinal direction of the parallel region 11, and the two electrodes 4 are parallel to each other. The two electrodes 4 are connected to the same wire harness 5 as a conductive medium for the heat generation layer 9.

[0028] In a preferred embodiment, the heating member includes a heat dissipation layer 10, the heat dissipation layer 10 being provided at a position corresponding to at least the irregular region 12, and the heat transfer section 3 includes at least the heat dissipation layer 10 provided at a position corresponding to the irregular region 12.

[0029] This embodiment further provides an embodiment of the heat transfer part 3. That is, the heat transfer part 3 is composed of at least the heat dissipation layer 10. The heat dissipation layer 10 has at least one side in contact with the heat generating layer 9 and is laid at least in the irregular region 12. The maximum area of ​​the area where the heat dissipation layer 10 is laid does not exceed the electrode 4 adjacent to the irregular region 12, i.e., the second electrode 42. As long as the heat dissipation layer 10 is provided, the minimum area of ​​the area where the heat dissipation layer 10 is laid is not limited. The heat transfer part 3 is composed of the heat dissipation layer 10 provided in the irregular region 12. The heat dissipation layer 10 is configured to dissipate heat generated from the heat generating layer 9 to the irregular region 12 to make the temperature in the irregular region 12 close to the temperature in the parallel region 11. In order to ensure heat dissipation efficiency, the area where the heat dissipation layer 10 is laid is made smaller than the area of ​​the irregular region 12.

[0030] Furthermore, the material of the heat dissipation layer 10 is graphene, carbon black, carbon nanotubes or a thermally conductive metal, and the sheet resistance of the heat dissipation layer 10 is smaller than the sheet resistance of the heat generation layer 9 .

[0031] Specifically, the heat dissipation layer 10 is composed of one or more of graphene, carbon black, carbon nanotubes, and thermally conductive metals. Examples of thermally conductive metals include aluminum and stainless steel. Due to the heat transfer function of materials such as graphene, excess temperature is transferred to the irregular region 12, and the heating temperature is kept constant throughout the irregular region 1. The heat dissipation layer 10 and the heat generation layer 9 may be bonded with tape or adhesive, or may not be bonded. As long as they are constantly in contact with each other due to the clamping action of the substrates 7 located above and below, the heat transfer conditions can be met.

[0032] In a preferred embodiment, the heat generating layer 9 is adhered to the substrate 7, the heat dissipation layer 10 partially overlaps the heat generating layer 9, and the portion of the heat dissipation layer 10 that does not overlap with the heat generating layer 9 is adhered to the substrate 7.

[0033] In a preferred embodiment, the heat dissipation layer 10 and the heat generation layer 9 are bonded to each other at their overlapping portions.

[0034] Specifically, the heat generating layer 9 is bonded to the substrate 7 adjacent to one side thereof. The heat generating layer 9 and the heat dissipation layer 10 have an overlapping area within the irregular region 12, and the heat generating layer 9 and the heat dissipation layer 10 are bonded to each other at the overlapping area. The area of ​​the heat dissipation layer 10 that overlaps with the heat generating layer 9 is bonded to the substrate 7 adjacent to one side of the heat generating layer 9.

[0035] Specifically, in order to uniformly heat the irregular region 12, a heat spread layer made of a heat spread material is added to the irregular region 12, and optionally, the heat spread material can be graphene, an aluminum sheet, etc.

[0036] In a preferred embodiment, the sheet resistance of the heat dissipation layer 10 is smaller than the sheet resistance of the heat generation layer 9 .

[0037] Specifically, by making the sheet resistance of the heat dissipation layer 10 relatively small, heat is easily transferred from the parallel region 11 to the irregular region 12, and the heating temperature of the irregular region 12 and the heating temperature of the parallel region 11 can be kept constant.

[0038] Example 2 Based on the above Example 1, this example provides another irregular heating structure. The contents of this example that are the same as those of Example 1 will be omitted. This example differs from Example 1 in the following points: The heat generating layer 9 is bonded to the substrate 7, and the shape of the heat dissipation layer 10 is the same as the shape of the portion of the heat generating layer 9 located in the irregular region 12.

[0039] Specifically, in this embodiment, the heat generating layer 9 extends within the irregular region 12 and has the same shape as the irregular region 12. In this embodiment, as shown in FIG. 5, the heat transfer section 3 is composed of the heat generating layer 9 provided within the irregular region 12 and the heat dissipation layer 10 provided within the irregular region 12. The heat generated by the heat generating layer 9 is transferred from the parallel region 11 into the irregular region 12, and the irregular region 12 is heated by the entire heat transfer section 3. This increases the heating efficiency and makes it possible to make the temperatures in the irregular region 12 and the parallel region 11 closer to each other.

The heat transfer unit 3 includes at least the heating wire 6 located at a position corresponding to the irregular region 12.

[0042] Specifically, the heating member further includes a heating wire 6, which is bent and disposed in the irregular region 12. Both ends of the heating wire 6 are welded to the two electrodes 4, respectively, or bonded by a conductive adhesive. After the two electrodes 4 are energized, the heating wire 6 generates heat to heat the irregular region 12. In this embodiment, as shown in FIG. 6 and FIG. 7, the heat transfer part 3 is made of the heating wire 6. The heating wire 6 is sewn to the substrate 7. If the substrate 7 is not suitable for sewing, the heating wire 6 is first sewn to the substrate 7 suitable for sewing, and then the substrate 7 with the heating wire 6 sewn thereto is bonded to the substrate 7 not suitable for sewing.

[0044] The heat transfer section 3 further includes a heat spreader layer 13. The material of the heat spreader layer 13 is graphene, carbon black, carbon nanotubes, or a thermally conductive metal.

[0045] Specifically, the shape of the heat spreading layer 13 corresponds to the irregular region 12. The heat spreading layer 13 is configured to uniformly distribute the heat generated by the heating wire 6 within the irregular region 12. In this embodiment, the heat transfer section 3 is composed of the heating wire 6 and the heat spreading layer 13, as shown in Figs. 8 and 9.
