[0026] In order to make those skilled in the art better understand the technical solutions of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely in combination with the drawings, and the description in this part is only exemplary and explanatory, and should not have any limiting effect on the protection scope of the present application. Specifically, the described embodiments are only some embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without any creative effort should also belong to the protection scope of the present application.

[0027] It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such process, method, product, or apparatus.

[0028] Example 1

[0029] As mentioned in the background section, in view of the problems in the prior art, this embodiment provides a novel automotive seat functional pad for installation on seat foam 4, including a comfort sponge 1, a protective lining 3, and a resistive conductor wire 2; the resistive conductor wire 2 is disposed between the comfort sponge 1 and the protective lining 3, and the protective lining 3 and the resistive conductor wire 2 are fixed to the comfort sponge 1 by an adhesive connector.

[0030] like Figure 1 As shown, the comfort sponge 1 is part of the foam system. Compared with the seat foam 4, it is softer and the two can be directly assembled and fixed without considering matching relationships. The resistive conductor wire 2 is coiled on the comfort sponge 1, and a protective lining layer 3 is provided on the side away from the comfort sponge 1. The protective lining layer 3 and the resistive conductor wire 2 are fixed to the comfort sponge 1 by adhesive to form the seat function cushion. Then, it is fixed to the seat foam 4 by adhesive or sewing to form a new seat foam system. Figure 7 As shown, in the traditional car seat structure, the heating pad, comfort sponge 1 and seat foam 4 need to be matched in sequence, which is a relatively complex structure.

[0031] By directly placing the resistive conductor wire 2 onto the comfort sponge 1 to form a heating pad, the comfort sponge 1, which is part of the foaming system, is easier to assemble with the seat foam 4. Compared with the traditional combination of heating pad, comfort sponge 1 and seat foam 4, it reduces the first-level matching relationship, thereby reducing the probability of mismatch. At the same time, there is no need to consider the matching relationship between the heating pad and the seat foam 4, and a larger heating area can be designed on the seat foam 4 to provide a larger heating area.

[0032] In a preferred embodiment, the adhesive connector is a thermoplastic adhesive connector, which is melted by hot pressing to fix the protective liner 3 and the resistive conductor wire 2 onto the comfort sponge 1.

[0033] In a preferred embodiment, the adhesive connector is attached to the surface of the comfort sponge 1 on the side near the resistive conductor wire 2.

[0034] As shown in Figures 2-4 the adhesive connector has a hot melt property, can start to melt to produce adhesion when heated to 100-150°C, and then the adhesive connector can be arranged on the surface of the comfort sponge 1 close to the resistive conductor wire 2, and the protective backing 3 and the resistive conductor wire 2 are fixed on the comfort sponge using a hot pressing process; the working temperature of the resistive conductor wire 2 is usually around 40-50°C, which cannot reach the hot melting point of the adhesive connector, and then the resistive conductor wire 2 will not affect the fixation between the resistive conductor wire 2, the protective backing 3 and the comfort sponge 1 when heated.

[0035] In a preferred embodiment, the adhesive connector is specifically a glue particle 5, a glue powder 6 or a glue film 7.

[0036] As shown in Figures 2-4 the glue particle 5, the glue powder 6 and the glue film 7 are all made of EVA glue, and the melting point is generally between 100-150°C, which can ensure that the adhesive connector still has stable adhesion when the resistive conductor wire 2 works and generates heat; when the glue particle 5 is used, the glue particles 5 can be arranged in a matrix on the comfort sponge 1; when the glue powder 6 is used, the glue powder 6 can be uniformly scattered on the surface of the comfort sponge 1; and when the glue film 7 is used, the glue film 7 can be attached to the surface of the comfort sponge 1, and the glue film 7 is uniformly provided with air holes, which can enhance the structural stability of the functional pad while avoiding affecting the air permeability of the functional pad.

[0037] In a preferred embodiment, the protective backing 3 is air-permeable lining, non-woven fabric, netting, cotton cloth or polyester cotton cloth.

[0038] As shown in Figure 1 the protective backing 3 made of air-permeable lining, non-woven fabric, netting, cotton cloth or polyester cotton cloth can have good air permeability and heat transfer property.

[0039] In a preferred embodiment, the resistive conductor wire 2 is electrically connected to a controller through a wire harness, and the controller is used to control the resistive conductor wire 2 to heat.

[0040] As shown in Figure 1 the controller is an ECU, the resistive conductor wire 2 is electrically connected to an external power supply, and the ECU can control the external power supply to supply power to the resistive conductor wire 2 to generate heat, so that the functional pad can realize the heating function.

[0041] In a preferred embodiment, the resistive conductor wire 2 is electrically connected to a controller through a wire harness, and the controller is used to detect the capacitance value of the resistive conductor wire 2 to detect the human body.

[0042] As shown in Figure 1As shown, the controller can also detect the change of the capacitance value of the resistive conductor wire 2 to detect whether there is a person sitting on the seat, and thus the functional cushion can realize the human body detection function.

[0043] Embodiment 2

[0044] The embodiment provides an automobile seat, which comprises a seat foam 4, a seat framework, and a seat cover, and further comprises a new type of automobile seat functional cushion as described in Embodiment 1.

[0045] As shown in Figure 5 and Figure 6 , the seat foam 4 is arranged on the seat framework, and the seat functional cushion is arranged between the seat foam 4 and the seat cover.

[0046] In a preferred embodiment, the seat foam 4 is provided with a groove 41, and the outer contour of the comfort sponge 1 matches the inner contour of the groove 41.

[0047] As shown in Figure 1 , the seat foam 4 is provided with a groove 41, and the inner contour of the groove 41 is the same in size and shape as the comfort sponge 1, so that the functional cushion provided by the embodiment can be matched with the seat foam 4 by placing the comfort sponge 1 in the groove 41.

[0048] In a preferred embodiment, the outer contour of the comfort sponge 1 matches the outer contour of the seat foam 4 close to the comfort sponge 1, and the comfort sponge 1 and the seat foam 4 are completely attached to each other on the side close to each other.

[0049] As shown in Figure 1 , the thickness of the seat foam 4 can also be appropriately reduced, the surface modeling of the side close to each other of the comfort sponge 1 and the seat foam 4 is adapted, and then fixed by means of bonding or sewing.

[0050] The principles and implementation modes of the present application are described by using specific examples in the present application, and the above embodiment descriptions are only used to help understand the method and core idea of the present application. The above description is only the preferred embodiment of the present application, and it should be pointed out that due to the limitation of language expression, there are infinite specific structures, and for ordinary skilled persons in the technical field, some improvements, decorations or changes can be made without departing from the principles of the present application, and the above technical features can also be combined in an appropriate manner; these improvements, decorations, changes or combinations, or the direct application of the inventive concept and technical scheme to other occasions without improvement, shall be regarded as the protection scope of the present application.
