[0089] Some embodiments of the present disclosure are given below in conjunction with the accompanying drawings and described in detail.

[0090] Example 1:

[0091] As shown in FIG1 , the first embodiment of the present disclosure provides an interior trim component comprising a frame 100, a heating layer 200, and an exterior layer 300, arranged sequentially from the inside to the outside. The heating layer 200 generates heat and transfers it outward (e.g., via radiation or conduction), achieving rapid heating and enhancing passenger comfort. The exterior layer 300 covers the frame 100 and heating layer 200, concealing them from view and enhancing the aesthetics of the interior trim component. The shape, pattern, color, and style of the exterior layer 300 can be selected as desired to achieve a desired appearance for the interior trim component.

[0092] In some embodiments, the exterior layer 300 may be made of leather, plastic, metal, glass, wood, or any other suitable material.

[0093] In some embodiments, the skeleton 100 and the heating layer 200 as well as the heating layer 200 and the appearance layer 300 can be fixed by bonding, for example, the skeleton 100 and the heating layer 200 as well as the heating layer 200 and the appearance layer 300 can be glued together by glue (such as environmentally friendly glue).

[0094] In some embodiments, a temperature sensor 400 may be provided on the frame 100 to monitor the temperature of the heating layer 200. In one embodiment, the temperature sensor 400 may be provided on the A surface of the frame 100. In one embodiment, the temperature sensor 400 may be provided on the B surface of the frame 100. In another embodiment, the temperature sensor 400 may also be provided in the frame 100, for example, in a through hole or through groove of the frame 100.

[0095] In some embodiments, a first extension piece 210 is provided on the heating layer 200, and a first wire 220 is connected to the first extension piece 210 (for example, the first wire 220 can be connected to the end of the first extension piece 210 and extend outward). The first wire 220 is used to conduct electricity and / or transmit electrical signals. By connecting the first wire 220 to a power source or a controller, the heating layer 200 can be powered or controlled, so that the heating layer 200 is heated to generate heat.

[0096] As shown in Figures 2 and 3, the first extension piece 210 is in a bent shape. It extends outward from the A side of the skeleton 100 (i.e., the side connected to the heating layer 200), bends again after exceeding the side wall of the skeleton 100, and continues to extend on the B side of the skeleton 100. That is, the first extension piece 210 is wrapped back to the B side of the skeleton 100 so that the first wire 220 is located on the B side of the skeleton 100. In this way, the first wire 220 can be hidden on the B side of the skeleton 100 to prevent it from being exposed and affecting the appearance of the interior decoration, thereby making the interior decoration more beautiful. The extension length of the first extension piece 210 on the B side of the skeleton 100 should be greater than the width of the parting line of the covering mold. In this way, when the appearance layer 300 covers the heating layer 200 and the skeleton 100, the first wire 220 will not affect the closing and crimping of the covering mold, and can be exposed outside the appearance layer 300, which is convenient for electrical connection with a power supply or controller, etc.; at the same time, it can avoid the weld point appearing on the mold parting line when the mold is closed during the covering process, causing quality or appearance defects at the edge of the interior decoration part.

[0097] In some embodiments, a first wire harness fastener 110 is provided on side B of the frame 100 for fastening the first wire 220 to fix the first wire's direction, prevent the first wire from interfering with surrounding components, and avoid excessive tangling of the first wire. The first wire harness fastener 110 may be a cable tie, a buckle, a slot, or any other suitable fastener.

[0098] In some embodiments, one end of the first wire 220 is connected to the end of the first extension piece 210, while the other end of the first wire 220 is connected to the female plug 120. Thus, when assembling the interior component, the circuit connection can be completed by simply plugging the male plug 130 into the female plug 120 and then connecting the male plug 130 to a power source or controller, which is very convenient. In another embodiment, the male and female plugs can also be interchangeable, so that one end of the first wire 220 can be connected to the end of the first extension piece 210, while the other end of the first wire 220 can be connected to the male plug. Therefore, when assembling the interior component, the male plug connected to the first wire can be plugged into another female plug, and then the other female plug can be connected to a power source or controller to complete the circuit connection.

[0099] As shown in Figures 4, 5, and 6, a cover body 140 may be further provided on side B of the frame 100, forming a cover cavity 150 between the cover body 140 and the frame 100. Portions of the first extension piece 210, the first wire 220, the first harness fastener 110, and the female plug 120 are at least partially located within the cover cavity 150. Thus, the cover body 140 covers the first wire 220, the first harness fastener 110, and the female plug 120, concealing them within the cover cavity 150. This not only provides protection, but also improves the appearance of the frame 100. The cover cavity 150 may be a hollow cavity with a front-to-back opening. The first extension piece 210 extends into the cover cavity 150 from one opening, and the male plug 130 then enters the cover cavity 150 from the other opening to mate with the female plug 120.

[0100] As shown in FIG6 , in an exemplary embodiment, the first harness fastener 110 may be a slot into which the first wire 220 is inserted. The slot has a certain toughness and can generate pressure with the first wire 220 to fix the first wire 220 .

[0101] As shown in FIG1 , a first through-hole 160 may be provided on the frame 100. The temperature sensor 400 is located on the A side of the frame 100 and is in contact with the heating layer 200 to monitor its temperature. A second wire 410 is connected to the temperature sensor 400. The second wire 410 is used to conduct electricity and / or transmit electrical signals. By connecting the second wire 410 to a power source or controller, power supply and signal transmission of the temperature sensor 400 can be achieved. The second wire 410 passes through the first through-hole 160 and reaches the B side of the frame 100, thereby concealing the second wire 410. In another embodiment, the temperature sensor 400 may be located in the first through-hole 160, with one side of the temperature sensor 400 in contact with the heating layer 200, and the other side of the temperature sensor 400 adhered to the B side of the frame 100 by adhesive tape. Thus, the temperature sensor 400 can be adhered to the frame 100 by the adhesive tape on the B side of the frame 100 to achieve fixation.

[0102] As shown in Figure 7, the B side of the skeleton 100 is provided with a second wiring harness fastener 170 for fixing the second wire 410 to fix the direction of the second wire, prevent the second wire from interfering with surrounding parts, and avoid excessive confusion of the second wire. The second wiring harness fastener 170 can be a cable tie, a buckle, a slot or any other suitable fastener. The second wiring harness fastener 170 can be at least partially located in the cover cavity 150 to achieve concealment and protection. The second wire 410 can be connected to the female plug 120 so that the line connection of the temperature sensor 400 can be achieved through the male plug 130. Here, the female plug 120 and the male plug 130 can also be interchangeable.

[0103] In some embodiments, the first harness fastener 110 , the cover 140 , the second harness fastener 170 , and the frame 100 may be integrally formed.

[0104] The number of first wires 220 and second wires 410 can be set as needed, for example, two each. The two first wires 220 are used to connect the positive and negative electrodes of the heating layer 200 and the positive and negative electrodes of the power supply or controller, respectively. The two second wires 410 are used to connect the positive and negative electrodes of the temperature sensor 400 and the positive and negative electrodes of the power supply or controller, respectively. The number of first wire harness fasteners 110 is the same as the number of first wires 220, and the number of second wire harness fasteners 170 is the same as the number of second wires 410.

[0105] The shape, thickness, material, etc. of the skeleton 100, the heating layer 200 and the appearance layer 300 can be selected as needed to obtain a desired interior decoration part.

[0106] As shown in FIG8 , the heating layer 200 may include a first protective layer 230, a graphene layer 240, an electrode layer 250, and a second protective layer 260, which are arranged in sequence from the inside to the outside. The electrode layer 250 and the graphene layer 240 are in contact with each other. One end of the first wire 220 is connected to the electrode layer 250, and the other end of the first wire 220 is connected to a power source or a controller so that electricity is supplied to the electrode layer 250 through the first wire 220. The graphene layer 240 is formed by depositing graphene on the first protective layer 230. After electricity is supplied, the graphene layer 240 is also energized and heated. The heated graphene transfers heat to the outside. Since graphene has a high thermal conductivity, it can achieve rapid heating in the vehicle. In FIG8 , there are two first wires 220, which are used to connect to the positive and negative poles of the power source to form a current path.

[0107] The electrode layer 250 may be formed by depositing a conductive material on the graphene layer 240 . The conductive material may be a metal material (eg, copper, silver, etc.), a carbon material, a metal oxide, a conductive ink, a conductive polymer, or any other suitable material.

[0108] The first protective layer 230 and the second protective layer 260 may be made of polyester cloth, thermoplastic polyurethane (TPU), thermoplastic resin (PC) or any other suitable material to protect the electrode layer 250 and the graphene layer 240 from being damaged.

[0109] In some embodiments, the first protective layer 230 and the graphene layer 240 as well as the second protective layer 260 and the electrode layer 250 may be fixed by bonding.

[0110] As shown in Figures 9A and 9B, when the electrode layer 250 is copper foil, the first extension sheet 210 includes a first protective layer 230, an electrode layer 250, and a second protective layer 260 arranged in sequence from the inside to the outside, and the first wire 220 connects the electrode layer 250. That is, there is no need to set the graphene layer 240 on the first extension sheet 210, and the graphene layer 240 only needs to be set on the main part of the heating layer 200.

[0111] As shown in Figures 10A and 10B, when the electrode layer 250 is a coating such as silver paste, the hierarchical structure of the first extension sheet 210 is the same as the main part of the heating layer 200, including a first protective layer 230, a graphene layer 240, an electrode layer 250 and a second protective layer 260 arranged in sequence from the inside to the outside, and the first wire 220 connects the electrode layer 250.

[0112] As shown in Figure 11, in an exemplary embodiment, the interior decoration component can be a seat back panel, which includes a seat frame 10 (equivalent to the frame 100 in Figure 1), a seat heating layer 20 (equivalent to the heating layer 200 in Figure 1) and a seat appearance layer 30 (equivalent to the appearance layer 300 in Figure 1) bonded in sequence from the inside to the outside. The seat appearance layer 30 covers the seat frame 10 and the seat heating layer 20 so that the occupants cannot see the seat frame 10 and the seat heating layer 20. The seat heating layer 20 can be heated to generate heat after being powered on. On the one hand, the heat can be directly radiated to the occupants in front and behind the seat and other spaces in the vehicle. On the other hand, the heat can also be conducted to the occupants through contact between the occupants and the seat back panel, thereby achieving rapid heating in the vehicle and improving the comfort of the occupants.

[0113] It is understood that the interior component can also be a knee guard, glove box, roof, door panel, door panel armrest, center console armrest, armrest box cover, footrest, footrest, or any other suitable interior component. By changing the shape, thickness, and material of the frame 100, heating layer 200, and exterior layer 300 accordingly, different interior components can be formed.

[0114] Example 2:

[0115] As shown in Figure 12, the second embodiment of the present disclosure provides an interior trim component. The component comprises, arranged sequentially from the inside out, a frame 100, a heating layer 200, a sensing layer 500, and an exterior layer 300. The sensing layer 500 is a touch sensor, used to sense whether the interior trim component is being touched. The exterior layer 300 covers the frame 100, heating layer 200, and sensing layer 500, concealing them beneath the exterior layer 300 and enhancing the aesthetics of the interior trim component. In other words, the frame 100, heating layer 200, sensing layer 500, and exterior layer 300 can be sequentially bonded together. The interior trim component of the second embodiment has essentially the same structure as the first embodiment, differing only in that, in addition to the first embodiment, a sensing layer 500 is added between the heating layer 200 and the exterior layer 300, along with additional structures to complement the sensing layer 500.

[0116] A second extension piece 510 may be provided on the sensing layer 500 , and a third wire 520 may be connected to the second extension piece 510 . The third wire 520 is used for powering and / or transmitting electrical signals. By connecting the third wire 520 to a power source and / or a controller, power supply and signal transmission of the sensing layer 500 may be achieved.

[0117] The second extension piece 510 also has a curved shape. It extends outward from the A surface of the frame 100, bends beyond the sidewall of the frame 100, and continues to extend along the B surface of the frame 100, wrapping around the B surface of the frame 100. This allows the third wire 520 to be located on the B surface of the frame 100. This conceals the third wire 520 on the B surface of the frame 100, preventing it from being exposed and affecting the appearance of the interior component, thereby enhancing the aesthetics of the interior component. The extension length of the second extension piece 510 on the B surface of the frame 100 should be greater than the width of the parting line of the coating mold. In this way, when the exterior layer 300 covers the sensing layer 500, the heating layer 200, and the frame 100, the third wire 520 is not covered by the exterior layer 300 but remains outside the exterior layer 300, facilitating electrical connection with a power source or controller. The structure of the second extension piece 510 is identical to that of the first extension piece 210. For details, please refer to the first embodiment and will not be repeated here.

[0118] The B side of the skeleton 100 may be provided with a third wiring harness fastener (not shown in the figure) for fastening the third wire 520 to fix the direction of the third wire, prevent the third wire from interfering with peripheral parts, and avoid the third wire from being too messy. The third wiring harness fastener can be a cable tie, a buckle, a slot or any other suitable fastener. The third wiring harness fastener can be at least partially located in the covering cavity 150 to achieve concealment and protection. The third wire 520 can be connected to the female plug 120 so as to achieve line connection of the sensing layer 500 through the male plug 130. Here, the female plug 120 and the male plug 130 can also be interchangeable.

[0119] In the present disclosure, as described above, the first, second, and third wire harness fasteners may be cable ties, buckles, slots, or any other suitable fasteners, wherein the slot may be understood as a wire harness securing groove for securing a single wire harness. Alternatively, the first, second, and third wire harness fasteners may be configured as adhesive fastening structures or as recesses or grooves for receiving multiple wire harnesses.

[0120] In this embodiment, the first wire harness fastener 110 , the covering body 140 , the second wire harness fastener 170 , the third wire harness fastener, and the frame 100 may be integrally formed.

[0121] It is understandable that the first wire harness fastener 110, the second wire harness fastener 170 and the third wire harness fastener can be independent wire harness fasteners or can be formed into the same wire harness fastener; that is, the first wire harness, the second wire harness and the third wire harness can be fixed on different wire harness fasteners respectively or can be fixed on the same wire harness fastener.

[0122] It is understandable that the sensing layer 500 can also be set between the heating layer 200 and the skeleton 100. In this case, the temperature sensor 400 can be attached to the sensing layer 500 to monitor its temperature or attached to the heating layer 200 after passing through the sensing layer 500 to monitor the temperature of the heating layer 200.

[0123] In some embodiments, the area of ​​the sensing layer 500 may be greater than or equal to the area of ​​the heating layer 200 .

[0124] In some embodiments, the interior trim may further include a temperature controller (not shown in the figure), which is electrically connected to the heating layer 200, the temperature sensor 400 and the sensing layer 500, respectively. For example, the temperature controller can be connected to a male plug, thereby being connected to the temperature sensor 400 and the sensing layer 500. The temperature controller is used to receive the temperature monitored by the temperature sensor 400 and the sensing signal transmitted by the sensing layer 500, and control the heating of the heating layer 200 according to the temperature and the sensing signal, thereby controlling the temperature of the interior decoration. For example, when the temperature monitored by the temperature sensor 400 is too high, the temperature of the surface of the interior decoration will also be too high. If it exceeds 43°C, if the occupant touches the surface of the interior decoration for a long time, it will cause low-temperature burns. Therefore, the controller can determine whether the temperature exceeds a first threshold value (for example, 43°C). If so, it determines whether the occupant has touched the interior decoration according to the sensing signal. If it is determined according to the sensing signal that the occupant has touched the interior decoration, the temperature is lowered to the first threshold value by controlling the output of the heating layer 200 (for example, by providing a pulse voltage with a preset duty cycle to the heating layer 200). If it is determined according to the sensing signal that the occupant has not touched the interior decoration, the temperature is raised to the second threshold value (for example, 70°C) by controlling the output of the heating layer 200, so as to heat the vehicle faster.

[0125] The temperature controller may be connected to a vehicle electronic control unit (ECU) so as to implement temperature control through the ECU and to supply power to the temperature controller, the heating layer 200 , the temperature sensor 400 and the sensing layer 500 .

[0126] In some embodiments, the sensing layer 500 may include a third protective layer, a conductive layer, and a fourth protective layer arranged in sequence. The conductive layer is made of a conductive material, and the conductive material includes a metal-based material, a carbon-based material, a metal oxide, a conductive ink, a conductive polymer, or any other suitable material. The third protective layer and the fourth protective layer can be made of polyester cloth, thermoplastic polyurethane elastomer (TPU), thermoplastic resin (PC), or any other suitable material. The third wire 520 is connected to the conductive layer. At this time, the sensing layer 500 is a single-pole plate to ground capacitor. When the surface of the interior part is touched by a human body, it is equivalent to a human body capacitor connected in parallel to the single-pole plate capacitor. The size of the human body capacitor is related to the area at the time of touch. The sensing unit in the temperature controller can detect the human body capacitance signal value and determine that the surface of the interior part is touched by a human body.

[0127] Example 3:

[0128] As shown in Figure 13, the third embodiment of the present disclosure provides an interior component, which differs from the interior component of the second embodiment in that: the heating layer 200 and the sensing layer 500 are integrated together to form a functional layer 600, and the functional layer 600 has both heating and touch sensing functions; the first extension piece 210 and the second extension piece 510 are also formed into the same extension piece (i.e., the third extension piece) 610, and the first wire 220 and the third wire 520 are connected to the third extension piece 610. The third extension piece 610 is bent and extends outward from the A surface of the skeleton 100, bends again after exceeding the side wall of the skeleton 100, and continues to extend on the B surface of the skeleton 100, thereby wrapping around to the B surface of the skeleton 100.

[0129] As shown in Figure 14, in an exemplary embodiment, the functional layer 600 can be improved on the basis of the heating layer 200 of Figure 8. Specifically, it is only necessary to lead out a third wire 520 on the electrode layer 250 for capacitive signal transmission. At this time, the graphene layer 240 plays both a heating role and a capacitive sensor role. On the one hand, the graphene layer 240 can transfer heat to the outside through heating. On the other hand, when the surface of the interior part is touched, a capacitance will be generated between the graphene layer 240 and the touching object. The capacitance signal is transmitted to the temperature controller by the third wire 520, thereby determining that the interior part is touched.

[0130] Example 4:

[0131] As shown in Figure 15, the fourth embodiment of the present disclosure provides an interior trim component. Based on the third embodiment, this component incorporates a foam layer 700 between the functional layer 600 and the exterior layer 300. The remaining structure is identical to the interior trim component of the third embodiment. Foam offers a range of advantages, including elasticity, light weight, rapid pressure-sensitive fixation, ease of use, flexible bending, ultra-thinness, and reliable performance. The addition of foam layer 700 makes the interior trim component softer and more comfortable to the touch.

[0132] As shown in Figure 16, the foam layer 700 of the interior decoration part of the fourth embodiment can also be arranged between the functional layer 600 and the skeleton 100. In this case, a second through hole 710 is provided on the foam layer 700, and the temperature sensor 400 is located on the A side of the foam layer 700 (the side connected to the functional layer 600). The second wire 410 of the temperature sensor 400 is hidden on the B side of the skeleton 100 after passing through the second through hole 710 and the first through hole 160 in sequence.

[0133] It is understandable that a foam layer may be added to the interior parts of the first embodiment and the interior parts of the second embodiment. When the foam layer 700 is added to the interior parts of the first embodiment, the foam layer 700 may be arranged between the appearance layer 300 and the heating layer 200 or between the heating layer 200 and the frame 100; when the foam layer 700 is added to the interior parts of the second embodiment, the foam layer 700 may be located between the appearance layer 300 and the sensing layer 500 (or the heating layer 200) or between the heating layer 200 (or the sensing layer 500) and the frame 100.

[0134] In the interior parts of the embodiment of the present disclosure, heat is transferred to the outside by heating the heating layer 200, which can achieve rapid heating of the vehicle interior and improve the comfort of the passengers; temperature control can be achieved through real-time monitoring of the temperature by the temperature sensor 400 and the touch sensing signal of the sensing layer 500 to avoid burns caused by the high temperature of the interior parts when the passengers touch the surface of the interior parts; the foam layer 700 can make the interior parts soft and more comfortable.

[0135] Embodiment 5:

[0136] As shown in Figures 17A, 17B, 17C, 17D and 17E, a fifth embodiment of the present disclosure provides an interior decoration component, which includes a frame 100, a heating layer 200 and an appearance layer 300 arranged in sequence from the inside to the outside, a first extension piece 210 is provided on the heating layer 200, a welding point 211 is provided on the first extension piece 210, a first wire 220 is connected to the welding point 211, and thus electrically connected to the heating layer 200, by connecting the first wire 220 to a power source or a controller, The heating layer 200 can be powered or controlled, so that the heating layer 200 is heated to generate heat; the first extension piece 210 can be bent, and it can extend outward from the A surface of the skeleton 100, bend again after exceeding the side wall of the skeleton 100, and continue to extend on the B surface of the skeleton 100 (that is, wrap around to the B surface of the skeleton 100), so that the welding point 211 and the first wire 220 are located on the B surface of the skeleton 100, avoiding the welding point 211 and the first wire 220 being exposed and affecting the beauty of the interior parts.

[0137] The heating layer 200 includes multiple heating units (e.g., graphene heating units) 270. Heating units 270 are also provided on the first extension piece 210. Each heating unit 270 is electrically connected to each other to achieve heating when powered. A temperature sensor 400 is secured to the first extension piece 210 and, along with the first extension piece 210, is bent toward the B side of the framework 100 to conceal it. The temperature sensor 400 contacts the heating units 270 on the first extension piece 210 to measure their temperature. A second wire 410 is connected to the temperature sensor 400 for powering and / or transmitting electrical signals. Connecting the second wire 410 to a power source or controller enables power supply and signal transmission to the temperature sensor 400. Solder points 211 are provided on the heating units 270 on the first extension piece 210. When the first wire 220 is connected to a power source, power is supplied to the heating units 270 on the first extension piece 210 and the heating layer 200, thereby heating the heating layer 200.

[0138] The first wire 220 and the second wire 410 can be connected to a plug 280 , and the first wire 220 and the second wire 410 can be conveniently connected to a power source or a controller through the plug 280 .

[0139] The exterior layer 300 can cover the frame 100 and heating layer 200 to conceal them from view, enhancing the aesthetics of the interior component. During this process, the exterior layer 300 can extend a predetermined length onto the B-side of the frame 100 to cover the welds 211 and temperature sensor 400 on the first extension piece 210, preventing them from being visible on the B-side of the frame 100. This further conceals the welds 211 and temperature sensor 400, enhancing the aesthetics of the interior component. Alternatively, the exterior layer 300 can leave the welds 211 and temperature sensor 400 uncovered, allowing them to be covered by a counterpart to the interior component, achieving a more aesthetically pleasing effect.

[0140] In the interior part of the fifth embodiment of the present disclosure, the connection between the first wire 220 and the heating layer 200 is achieved through the welding point 211 on the first extension piece 210, and the welding point 211 is hidden on the B side of the skeleton 100 by bending the first extension piece 210, making the interior part more beautiful; the temperature sensor 400 is fixed on the first extension piece 210 and contacts the heating unit 270 thereon, which can realize both temperature measurement and hiding of the temperature sensor 400.

[0141] Example 6:

[0142] 18A , 18B , 18C and 18D , the sixth embodiment of the present disclosure provides an interior component, which has a structure substantially the same as that of the fifth embodiment, except that the structure of the skeleton 100 and the manner in which the first extension piece 210 is bent to the B-side of the skeleton 100 are different. Specifically, in the sixth embodiment, as shown in Figure 18A, a first through groove 181 is provided on the skeleton 100, and the first through groove 181 is located near the edge of the skeleton 100. One end of the first extension piece 210 is bent at the first through groove 181 and passes through the first through groove 181 to reach the B side of the skeleton 100, and fits with the B side of the skeleton 100. That is, the first extension piece 210 passes through the first through groove 181 and is wrapped around the B side of the skeleton 100, thereby realizing the hiding of the welding point 211 and the temperature sensor 400; in this way, the first extension piece 210 can be avoided from being bent at the edge of the skeleton 100 and wrapped around the B side of the skeleton 100, thereby avoiding the protrusion from damaging the first extension piece 210 when the edge of the skeleton 100 has a protrusion. For example, as shown in Figures 18B and 18C, the edge of the skeleton 100 may be provided with a raised portion 100a. When a foam layer 700 is provided between the appearance layer 300 and the heating layer 200, the raised portion 100a can limit the foam layer 700. At this time, if the first extension piece 210 is bent from the edge of the skeleton 100 to the B side of the skeleton 100, the raised portion 100a will cause the first extension piece 210 to be bent multiple times, resulting in an increased risk of damage to the first extension piece 210. However, through the sixth embodiment of the present disclosure, the first extension piece 210 can pass through the first through groove 181 near the raised portion 100a to achieve reverse packaging, without the need for multiple bending around the raised portion 100a, thereby avoiding damage to the first extension piece 210.

[0143] After the first extension piece 210 is wrapped from the first through-groove 181 to the B side of the frame 100, the blocking cover 182 can be inserted into the first through-groove 181 to fill the first through-groove 181. That is, the upper surface of the blocking cover 182 is substantially flush with the upper surface of the frame 100, where the upper surface is the side close to the heating layer 200. The blocking cover 182 can match the first through-groove 181, so that the blocking cover 182 is inserted into the first through-groove 181 and can be fixed to the frame 100.

[0144] As shown in Figure 18D, in some embodiments, the blocking cover 182 may not be provided on the skeleton 100, that is, after the first extension piece 210 is wrapped from the first through groove 181 to the B side of the skeleton 100, the first through groove 181 does not need to be filled with the blocking cover 182.

[0145] In some embodiments, a soft layer may also be provided between the skeleton 100 and the heating layer 200. The soft layer is used to provide a soft touch and can be made of any suitable soft material, such as foam, soft-touch polypropylene, etc. An incision may be provided on the soft layer, and the first extension piece 210 may pass through the incision on the soft layer and the first through groove 181 on the skeleton 100 in sequence, and be wrapped back to the B side of the skeleton 100.

[0146] In the interior component of the sixth embodiment of the present disclosure, a first through groove 181 is opened on the skeleton 100, so that the first extension piece 210 passes through the first through groove 181 and is wrapped around the B side of the skeleton 100, thereby preventing the first extension piece 210 from bending at the edge of the skeleton 100 and wrapping around the B side of the skeleton 100, thereby preventing the protrusion from causing damage to the first extension piece 210 when there is a protrusion on the edge of the skeleton 100.

[0147] Embodiment seven:

[0148] As shown in Figures 19A, 19B, and 19C, a seventh embodiment of the present disclosure provides an interior trim component comprising, from inside to outside, a frame 100, a heating layer 200, and an exterior layer 300. The structure of the interior trim component is substantially the same as that of the fifth embodiment, except that the first extension piece 210 does not include a heating unit 270, nor does the temperature sensor 400. Instead, a second through-slot 190 is provided in the frame 100. The temperature sensor 400 is retained in the second through-slot 190 and contacts the heating unit 270 on the heating layer 200, thereby measuring the temperature of the heating layer 200. The second wire 410 of the temperature sensor 400 passes through the second through-slot 190 and reaches the B side of the frame 100, thereby being concealed. In other words, in the seventh embodiment, the solder joint 211 is concealed by the first extension piece 210 being wrapped around the B side of the frame 100, while the second wire 410 passes through the second through-slot 190 and reaches the B side of the frame 100, thereby being concealed. Similar to the fifth embodiment, the first wire 220 is connected to the soldering point 211 , and the first wire 220 and the second wire 410 can be connected to the plug 280 .

[0149] As shown in Figures 19C and 19D, the temperature sensor 400 may include a base 420 and a probe 430. The probe 420 is fixed on the base 420. The second wire 410 is electrically connected to the probe 420. The base 420 matches the second through-groove 190 on the skeleton 100. When the base 420 is inserted into the second through-groove 190, the base 420 can be fixed to the skeleton 100, and at the same time, the probe 430 can be in close contact with the heating unit 270 on the heating layer 200, thereby detecting the temperature of the heating layer 200 through the probe 430.

[0150] In the interior part of the seventh embodiment of the present disclosure, the temperature sensor 400 is fixed in the second through-groove 190 and is in direct contact with the heating layer 200 to achieve temperature measurement. The second wire 410 passes through the second through-groove 190 to reach the B side of the skeleton 100 to achieve concealment, making the interior part more beautiful.

[0151] As shown in FIG20 , the temperature sensor 400 is arranged and fixed to the B surface of the skeleton 100 by means of adhesive tape 440. It is also conceivable that the temperature sensor 400 can be fixed to the B surface of the skeleton 100 by other means. In one embodiment, the temperature sensor 400 is fixed to the B surface of the skeleton 100 by means of an adhesive. In another embodiment, the temperature sensor 400 is fixed to the B surface of the skeleton 100 by means of a buckle or a slot. Regarding the arrangement position of the temperature sensor 400 on the B surface of the skeleton 100, in one embodiment, the temperature sensor 400 can be located between the exterior layer 300 wrapped around the B surface of the skeleton 100 and the skeleton 100. In another embodiment, the temperature sensor 400 can be located on the B surface of the skeleton 100 and exposed to the air. When the temperature sensor 400 is positioned on the B surface of the frame 100, the temperature measured by the temperature sensor 400 is the temperature of the B surface of the frame 100. The temperature of the B surface of the frame 100 corresponds to the temperature of the A surface of the exterior layer 300 or the outer surface temperature of the sample. Therefore, the temperature measured by the temperature sensor 400 can be used to infer the temperature of the A surface of the exterior layer 300 or the outer surface temperature of the sample. For clarity, the heating layer is not shown in this figure. It is understood that the heating layer is positioned between the exterior layer 300 and the frame 100, or that the heating element is already fixed to the frame 100.

[0152] The method for producing an interior trim component according to the present disclosure will be described below with reference to FIG. 21 .

[0153] As shown in FIG21 , a skeleton 100, a heating layer 200, and an exterior layer 300 may first be provided and pre-treated in step S1. The heating layer 200 may include a graphene layer, wherein the graphene layer may be formed by depositing graphene. The heating layer 200 may be configured as a graphene heating pad. The pre-treatment of the skeleton 100 and the heating layer 200 may include a glue spraying process. The pre-treatment of the exterior layer 300 may also include a glue spraying process. The pre-treatment of the skeleton 100 and the heating layer 200 and the pre-treatment of the exterior layer 300 may be performed simultaneously or at different time points.

[0154] Then, in step S2, the heating layer 200 can be fixed to the frame 100, thereby forming a semi-finished assembly. Here, the heating layer 200 can be bonded to the frame 100. The above-mentioned glue spraying treatment of the heating layer 200 and the frame 100 can facilitate this bonding. After the heating layer 200 is fixed to the frame 100 and the semi-finished assembly is formed, the semi-finished assembly can be subjected to a secondary glue spraying to facilitate the subsequent bonding of the appearance layer 300 to the heating layer 200 of the semi-finished assembly. The above-mentioned pretreatment of the appearance layer 300, such as the glue spraying treatment, can be performed after the semi-finished assembly has been formed.

[0155] Finally, in step S3, the exterior layer 300 can be wrapped around and secured to the semi-finished component, thereby forming an interior trim. In this interior trim, the frame 100, heating layer 200, and exterior layer 300 are sequentially arranged from the inside out. Specifically, the exterior layer 300 can be wrapped around and secured to the semi-finished component using a hot press wrapping process. The hot press wrapping process also includes a finishing step for the finished product after wrapping. Specifically, after wrapping the exterior layer 300 around the semi-finished component to form a pre-wrapped component, the pre-wrapped component is trimmed. Ultimately, the interior trim can be obtained as a functional component. In this method, the first wire 220 can be connected to the heating layer 200 and concealed on the B surface of the frame 100.

[0156] The various steps of the above method can be performed manually and / or automatically, for example, by a machine. Specifically, the hot pressing and coating process is mainly performed by a machine. In another embodiment, the coating operation in the hot pressing and coating process can also be performed manually.

[0157] In one embodiment of the method, the graphene heating pad and the skeleton 100 serving as the heating layer 200 are first sprayed with glue; the graphene heating pad and the skeleton 100 are then bonded to form a semi-finished component; the bonded semi-finished component is then sprayed with glue for a second time, and an appearance layer 300 is provided and sprayed with glue at the same time. This spraying is for bonding the appearance layer 300 with the graphene heating pad in the semi-finished component; finally, the semi-finished component and the appearance layer 300 after spraying with glue are subjected to a hot pressing and coating process, and then the final interior part or functional part is obtained, wherein the first wire 220 is connected to the heating layer 200, and the first wire 220 is hidden at the B side of the skeleton 100.
