[0030] The preferred embodiments of the present utility model are given below in conjunction with the accompanying drawings and described in detail.

[0031] According to the seat back plate 1 with heating function of the utility model, a heating effect is provided for rear passengers 2 in a low temperature environment. The heating form of the seat back plate 1 varies according to different usage scenarios. The maximum heating temperature (saturation temperature) of the seat back plate 1 in different usage scenarios changes depending on whether the human body contacts it (including the contact duration).

[0032] like Figure 1 As shown, in the first usage scenario, the rear passenger 2 is in a normal sitting position, the seat back 1 is in contact with the seat back A, and there is a gap between the rear passenger 2 and the seat back 1. At this time, the temperature of the seat back 1 is set to the first temperature, and heat is provided to the rear passenger 2 through radiation heating.

[0033] like Figure 2 As shown, in the second usage scenario, the rear passenger 2 needs to use a footrest, or cooperate with zero gravity and various other seat deployment postures to relax, and the top of the seat back panel 1 gradually moves backward and downward away from the seat back A to expand and tilt to form a footrest, and the feet of the rear passenger 2 fit on the footrest, providing heat to the rear passenger 2 through heat conduction.

[0034] like Figure 3 As shown, in the third usage scenario, the seat back panel 1 is in contact with the seat back A, and the rear passenger 2 also needs to use a footrest, or cooperate with zero gravity and various other seat deployment postures to relax. The seat back panel 1 is folded forward with the seat back A to form a footrest, and the feet of the rear passenger 2 are placed on the footrest, providing heat to the rear passenger 2 through heat conduction.

[0035] In the second and third usage scenarios, taking into account the situations in which the rear passenger 2 uses the footrest with shoes on and takes off shoes, the seat back panel 1 provides two temperature settings: the second temperature (for use with shoes on) and the third temperature (for use with shoes off). The first temperature is greater than the second temperature and greater than the third temperature, wherein the first temperature is in the range of 60℃±5℃ to 70℃±5℃, the second temperature is in the range of 50℃±5℃ to 60℃±5℃, and the third temperature is in the range of 40℃±5℃ to 50℃±5℃. The first, second and third temperatures are the best recommended ranges considering human comfort, and multi-speed temperature adjustment modes can be provided according to various methods such as heating material design or circuit design (NTC temperature control, touch sensing temperature control). Users can control themselves within the recommended safety range to match different personal temperature preferences.

[0036] like Figure 4 and Figure 5 As shown, the seat back A includes a backrest frame A1, a backboard frame A2 and a backrest decorative layer A3 which are covered and installed on the backrest frame A1. According to the utility model, the seat back 1 with heating function suitable for the second usage scenario is a covering member using a flexible material as a decorative layer, including a backboard frame (i.e., a footrest frame) 11, a heat insulation layer 12, a heating pad 13 and a backboard decorative layer (i.e., a footrest decorative layer) 14, which are installed as a whole to the side of the backrest decorative layer A3 close to the passenger, wherein the backboard frame 11 is rotatably installed on the backrest frame A1, the heating pad 13 is used for heating to generate heat and transfer the heat to the outside, the heat insulation layer 12 is arranged between the backboard frame 11 and the heating pad 13 to prevent heat from being transferred to the seat back A, and the backboard decorative layer 14 covers the backboard frame 11, the heat insulation layer 12 and the heating pad 13, thereby making the appearance of the seat back 1 more beautiful.

[0037] The backrest frame A1 is a metal frame, and the backboard frame 11 is a plastic part. The plastic can be a polymer material such as TPE, PP, ABS, PA, PE, PC, etc.

[0038] The heat insulating layer 12 may be made of foam, foam cotton, glass fiber material, gel material, etc., and is used to prevent excessive heat transfer to the passenger side of the seat body.

[0039] like Figure 6As shown, the heating pad 13 includes a heating layer 131, an electrode layer 132 and a protective layer 133, wherein the heating layer 131 and the electrode layer 132 are sandwiched between two protective layers 133, and the heating layer 131 and the electrode layer 132 are adjacent to each other at the edge of the heating area, so that there is contact between the heating layer 131 and the electrode layer 132. The heating layer 131 is a thermal radiation heating material containing graphene and having good far-infrared release characteristics, the electrode layer 132 can be a metal wire, silver paste or copper foil, and the protective layer 133 can be a polymer such as PI or PU, or a fabric.

[0040] Among them, the back panel decoration layer 14 can be leather, fabric, or a decorative layer with enhanced heat dissipation function. It can be leather material or fiber product doped with high thermal conductivity materials, because the heat dissipation rate is increased by the doping of high thermal conductivity materials, or holes are opened on the decorative layer.

[0041] like Figure 7 As shown, the seat back panel 1 with heating function suitable for the third usage scenario according to the utility model is formed as a part of the seat back A and does not need to be rotated relative to the seat back A, that is, the back panel frame 11 is fixedly installed on the back panel frame A1, the heating pad 13 is used for heating to generate heat and transfer the heat to the outside, the heat insulation layer 12 is arranged between the back panel frame 11 and the heating pad 13 to prevent heat from being transferred to the seat back A, and the back panel decorative layer 14 covers the back panel frame 11, the heat insulation layer 12 and the heating pad 13 to hide the back panel frame 11, the heat insulation layer 12 and the heating pad 13 so that they cannot be seen, thereby making the appearance of the seat back panel 1 more beautiful.

[0042] The heating pad 13 can be designed and contoured according to the shape of the backrest frame A1.

[0043] The backboard frame 11 and the backrest frame A1 are fixed by snap fastening or bolts, and the hierarchical structures of the backboard frame 11, the heat insulation layer 12, the heating pad 13 and the backboard decoration layer 14 are fixed by gluing.

[0044] like Figure 8 As shown, the heat insulating layer 12 of the seat back panel 1 can be omitted.

[0045] like Fig. 9 As shown, the backboard frame 11 of the seat backboard 1 can be arranged between the heating pad 13 and the backboard decorative layer 14, that is, the backboard frame 11 is located near the rear passenger 2 of the heating pad 13 (see Figure 1-Figure 3 ) side, the back plate frame 11 is now perforated to facilitate the heat output by the heating pad 13 to be conducted out.

[0046] like Fig.10As shown, the seat back panel 1 further includes a sensor pad 15 disposed between the heating pad 13 and the back panel decorative layer 14. The sensor pad 15 is used to detect whether it is touched, and is used to control the heating pad 13 to adjust the temperature to prevent burns.

[0047] like Fig.11 As shown, the heating pad 13 of the seat back panel 1 can be integrated with a sensing function, that is, the heating layer and the sensing layer are configured as an integrally formed pad. In other words, the heating pad 13 is a dual-purpose functional membrane with an integrated sensing function. Specifically, Figure 6 As shown, the temperature sensor NTC 134 is fixedly mounted on the protective layer 133. The duty cycle output of the voltage is controlled by the electronic module to realize the contact sensing and heating functions on a single diaphragm.

[0048] like Fig.12 As shown, the seat back panel 1 also includes a heat dissipation layer 16 disposed between the heating pad 13 and the back panel decorative layer 14. The material of the heat dissipation layer 16 can be a heat dissipation coating or material with graphene, boron nitride, or metal powder as a dopant, or can be a material such as thermal conductive silicone. The heat dissipation layer 16 can withstand high temperatures, and its physical and chemical properties are stable and unchanged within the range of -40°C to 120°C.

[0049] like Fig.13 As shown, the backboard frame 11 of the seat backboard 1 can be integrated with a decorative function, that is, the frame layer and the decorative layer are integrally formed. In other words, the decorative layer is a plastic part.

[0050] like Fig.14 As shown, the backboard frame 11 of the seat backboard 1 can be integrated with heating and decoration functions, that is, the frame layer, the heating layer and the decoration layer are integrally formed. In other words, the decoration layer is a plastic part, and the interlayer is a heating pad. The heating pad 13 can be added during the injection molding process to form a seat backboard 1 with a heating pad 13 as an integral part. Fig.15 As shown. Graphene can also be mixed and extruded with polymer particles to obtain a heating pad material that can be heated by radiation and has the characteristics of a polymer sheet, and the material can be directly used as a decorative layer. The heating pad 13 is composited with the seat back panel 1 during the injection molding stage.

[0051] Obviously, the hierarchical arrangement of the heating pad 13, as well as the assembly process between the electronic components such as the wiring harness and the temperature sensor and the plastic parts of the seat back panel can be adjusted as needed. The hierarchical structure of the seat back panel 1 includes a back panel frame 11 (plastic part), a heat insulation layer 12 (foaming), a heating pad 13, a back panel decorative layer 14 (coating layer), a sensor pad 15 and a heat dissipation layer 16. There may be no heat insulation layer 12 and heat dissipation layer 16. The heating pad 13 and the sensor pad 15 can be integrated into one layer. The back panel decorative layer 14 can be fabric, single leather (including genuine leather, PU leather, PVC leather), and a cover (leather plus a composite layer). The sensor pad 15 is used to identify human body contact. In the radiation heating state, once human body contact occurs, the heating element will control the heating temperature to the fourth temperature. The fourth temperature is a temperature value to protect the human body from low-temperature burns. Here, it is specified as 45°C and below to prevent burns. In this way, the utility model can provide heating for the rear passengers 2 in a lower temperature environment, and provide a faster heating rate and high comfort in the form of radiation heating. The application of graphene material can also provide infrared therapy effect for the knees of rear passengers 2. The application of heating of seat back panel 1 can reduce the application of air conditioner in temperature regulation, and reduce the energy loss of the whole vehicle when used in conjunction with air conditioner.

[0052] The above is only a preferred embodiment of the utility model, and is not intended to limit the scope of the utility model. The above embodiments of the utility model can also be modified in various ways. That is, all simple, equivalent changes and modifications made according to the claims and the contents of the specification of the utility model application fall within the scope of protection of the claims of the utility model patent. The conventional technical contents are not described in detail in the utility model.
