[0063] The preferred embodiments of the present utility model are given below in conjunction with the accompanying drawings and described in detail.

[0064] Embodiment 1:

[0065] like Figure 1 As shown, the first embodiment of the utility model provides an interior decoration part, which includes a frame 100, a heating layer 200 and an appearance layer 300 arranged in sequence from the inside to the outside, wherein the heating layer 200 is used to generate heat by heating and transfer the heat to the outside (for example, by radiant heat transfer or by conductive heat transfer) to achieve rapid heating and improve the comfort of the passengers in the vehicle; the appearance layer 300 covers the frame 100 and the heating layer 200 to hide the frame 100 and the heating layer 200 and make them invisible, so that the appearance of the interior decoration part is more beautiful. The shape, pattern, color, style, etc. of the appearance layer 300 can be selected as needed to give the interior decoration part a desired appearance.

[0066] In some embodiments, the exterior layer 300 may be made of leather, plastic, metal, glass, wood, or any other suitable material.

[0067] 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 are glued together by adhesive (or environmentally friendly glue).

[0068] In some embodiments, a temperature sensor 400 may be provided on the skeleton 100 for monitoring the temperature of the heating layer 200 .

[0069] In some embodiments, a first extension sheet 210 is provided on the heating layer 200, and a first wire 220 is connected to the first extension sheet 210 (for example, the first wire 220 can be connected to the end of the first extension sheet 210 and extend outward). The first wire 220 is used to power on 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.

[0070] like Figure 2 and Figure 3As shown, the first extension piece 210 is in a bent shape, extending outward from the A surface of the frame 100 (i.e., the surface connected to the heating layer 200), and then bending again after exceeding the side wall of the frame 100, and continuing to extend on the B surface of the frame 100, that is, the first extension piece 210 is reversed to the B surface of the frame 100, so that the first wire 220 is located on the B surface of the frame 100, so that the first wire 220 can be hidden on the B surface of the frame 100, avoiding exposure 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 surface of the frame 100 should be greater than the width of the parting line of the coating mold, so that when the appearance layer 300 covers the heating layer 200 and the frame 100, the first wire 220 will not affect the closing and crimping of the coating mold, and can be exposed outside the appearance layer 300, which is convenient for electrical connection with a power supply or a controller, etc.; at the same time, it can be avoided that when the mold is closed during the coating process, the welding point will appear on the mold parting line to cause quality or appearance defects at the edge of the interior decoration.

[0071] In some embodiments, the first harness fastener 110 is provided on the B surface of the frame 100 for fastening the first wire 220 to fix the direction of the harness, prevent the harness from interfering with surrounding parts, and avoid excessive confusion of the harness. The first harness fastener 110 can be a cable tie, a buckle, a slot, or any other suitable fastener.

[0072] In some embodiments, one end of the first wire 220 is connected to the end of the first extension piece 210, and the other end is connected to the female plug 120. In this way, when assembling the interior decoration parts, it is only necessary to plug the male plug 130 into the female plug 120, and then connect the male plug 130 to the power supply or controller to complete the circuit connection, which is very convenient.

[0073] like Figure 4 , Figure 5 and Figure 6 As shown, the B surface of the frame 100 may also be provided with a covering body 140, and a covering cavity 150 is formed between the covering body 140 and the frame 100. Part 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 in the covering cavity 150, so that the first wire 220, the first harness fastener 110, and the female plug 120 are covered by the covering body 140, so that they are hidden in the covering cavity 150, which can play a protective role on the one hand and improve the appearance of the frame 100 on the other hand. The covering cavity 150 can be a cavity opened from front to back, and the first extension piece 210 extends into the covering cavity 150 from one opening of the covering cavity 150, and then the male plug 130 can enter the covering cavity 150 from the other opening to be plugged with the female plug 120.

[0074] like Figure 6As shown, 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 and fix the first wire 220 .

[0075] like Figure 1 As shown, the frame 100 may be provided with a first through hole 160, the temperature sensor 400 is located on the A surface of the frame 100 and is attached to the heating layer 200 to monitor its temperature; the temperature sensor 400 is connected with a second wire 410, the second wire 410 is used for powering and / or transmitting electrical signals, and the second wire 410 is connected to a power source or a controller to achieve power supply and signal transmission of the temperature sensor 400; the second wire 410 passes through the first through hole 160 and reaches the B surface of the frame 100 to achieve hiding of the second wire 410. The temperature sensor 400 can be bonded to the frame 100 by a tape located on the B surface to achieve fixation.

[0076] like Figure 7 As shown, the B side of the skeleton 100 is provided with a second harness fastener 170 for fixing the second wire 410 to fix the direction of the harness, prevent the harness from interfering with the surrounding parts, and avoid the harness from being too messy. The second harness fastener 170 can be a cable tie, a buckle, a slot or any other suitable fastener. The second harness fastener 170 can be at least partially located in the covering cavity 150 to achieve hiding and protection. The second wire 410 can be connected to the female plug 120 so as to achieve line connection of the temperature sensor 400 through the male plug 130.

[0077] In some embodiments, the first harness fastener 110 , the cover 140 , the second harness fastener 170 , and the frame 100 may be integrally formed.

[0078] The number of the first wires 220 and the second wires 410 can be set as needed, for example, both can be 2, 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, respectively, and 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, respectively. The number of the first harness fasteners 110 is the same as the number of the first wires 220, and the number of the second harness fasteners 170 is the same as the number of the second wires 410.

[0079] The shapes, thicknesses, materials, 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.

[0080] like Figure 8As shown, 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 is connected to a power source 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 will also be energized and heated. The heated graphene will transfer heat to the outside. Since the thermal conductivity of graphene is very high, it can achieve rapid heating in the car. Figure 8 In the embodiment, there are two first conducting wires 220, which are respectively used to connect to the positive and negative electrodes of the power source to form a current path.

[0081] 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.

[0082] 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.

[0083] 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.

[0084] like Fig.9A and Fig. 9B As shown, 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 to say, 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.

[0085] like Fig. 10A and Fig. 10B As shown, 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.

[0086] like Fig.11 As shown, in an exemplary embodiment, the interior trim may be a seat back panel, which includes a seat frame 10 (equivalent to Figure 1 The frame 100 in the chair and the heating layer 20 (equivalent to Figure 1 The heating layer 200) and the chair appearance layer 30 (equivalent to Figure 1 The appearance layer 300 in the seat 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 the contact between the occupants and the seat back panels, thereby achieving rapid heating in the vehicle and improving the comfort of the occupants.

[0087] It is understandable that the interior trim may also be a knee baffle, a glove box, a ceiling, a door panel, a door panel armrest, a center console armrest, an armrest box cover, a footrest, a footrest or any other suitable interior trim. By making corresponding changes to the shape, thickness and material of the frame 100, the heating layer 200 and the appearance layer 300, different interior trims may be formed.

[0088] Embodiment 2:

[0089] like Fig.12 As shown, the second embodiment of the utility model provides an interior decoration part, which includes a frame 100, a heating layer 200, a sensing layer 500 and an appearance layer 300 arranged in sequence from the inside to the outside. The sensing layer 500 is a touch sensor for sensing whether the interior decoration part is touched. The appearance layer 300 covers the frame 100, the heating layer 200 and the sensing layer 500 so that they are hidden under the appearance layer 300, making the interior decoration part more beautiful. In other words, the frame 100, the heating layer 200, the sensing layer 500 and the appearance layer 300 can be bonded together in sequence. The structure of the interior decoration part of the second embodiment is basically the same as that of the interior decoration part of the first embodiment. The only difference is that, on the basis of the first embodiment, the second embodiment adds a sensing layer 500 between the heating layer 200 and the appearance layer 300, and adds some structures matching the sensing layer 500.

[0090] A second extension sheet 510 may be provided on the sensing layer 500, and a third wire 520 is connected to the second extension sheet 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 can be achieved.

[0091] The second extension piece 510 is also in a bent shape, extending outward from the A surface of the frame 100, bending again after exceeding the side wall of the frame 100, and continuing to extend on the B surface of the frame 100, so as to be wrapped back to the B surface of the frame 100, and the third wire 520 is located on the B surface of the frame 100, so that the third wire 520 can be hidden on the B surface of the frame 100 to avoid being exposed and affecting the appearance of the interior decoration, thereby making the interior decoration more beautiful. 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, so that when the appearance layer 300 covers the sensing layer 500, the heating layer 200 and the frame 100, the third wire 520 will not be covered by the appearance layer 300, but is located outside the appearance layer 300, so as to facilitate electrical connection with a power supply or a controller. The structure of the second extension piece 510 is the same as that of the first extension piece 210, and the details can be referred to the first embodiment, which will not be repeated here.

[0092] The B surface of the skeleton 100 may be provided with a third harness fastener (not shown in the figure) for fastening the third wire 520 to fix the direction of the harness, prevent the harness from interfering with the surrounding parts, and avoid the harness from being too messy. The third harness fastener may be a cable tie, a buckle, a slot, or any other suitable fastener. The third harness fastener may be at least partially located in the covering cavity 150 to achieve hiding and protection. The third wire 520 may be connected to the female plug 120 so as to achieve line connection of the sensing layer 500 through the male plug 130.

[0093] In this embodiment, the first harness fastener 110 , the cover 140 , the second harness fastener 170 , the third harness fastener and the frame 100 may be integrally formed.

[0094] It is understandable that the first harness fastener 110, the second harness fastener 170 and the third harness fastener may be independent harness fasteners or may be formed as the same harness fastener; that is, the first harness, the second harness and the third harness may be fixed on different harness fasteners or on the same harness fastener.

[0095] 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 pass through the sensing layer 500 and then attached to the heating layer 200 to monitor the temperature of the heating layer 200.

[0096] In some embodiments, the area of ​​the sensing layer 500 may be greater than or equal to the area of ​​the heating layer 200 .

[0097] In some embodiments, the interior decoration part may also 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 connecting 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, so as to control 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 the first threshold value (for example, 43°C). If so, it determines whether the occupant touches the interior decoration according to the sensing signal. If so, it controls the output of the heating layer 200 (for example, it can be achieved by providing a pulse voltage with a preset duty cycle to the heating layer 200) to achieve cooling and reduce the temperature to the first threshold value. If not, 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 interior of the vehicle faster.

[0098] The temperature controller may be connected to an electronic control unit (ECU) of the vehicle 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 .

[0099] 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 material, a carbon material, a metal oxide, a conductive ink, a conductive polymer or any other suitable material; the third protective layer and the fourth protective layer may 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, and 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 connecting a human body capacitor 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.

[0100] Embodiment three:

[0101] like Fig.13As shown, the third embodiment of the utility model provides an interior decoration part, which is different from the interior decoration part 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 in a bent shape 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.

[0102] like Fig.14 As shown, in an exemplary embodiment, the functional layer 600 may be Figure 8 Specifically, it is only necessary to lead out the third wire 520 on the electrode layer 250 for capacitive signal transmission. At this time, the graphene layer 240 plays a role of heating and a capacitive sensor. 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 decoration part is touched, a capacitance will be generated between the graphene layer 240 and the touched object. The capacitance signal is transmitted to the temperature controller by the third wire 520, so as to determine that the interior decoration part is touched.

[0103] Embodiment 4:

[0104] like Fig.15 As shown, the fourth embodiment of the utility model provides an interior decoration part, which, based on the third embodiment, adds a foam layer 700 between the functional layer 600 and the appearance layer 300, and the rest of the structure is the same as the interior decoration part of the third embodiment. Foam has a series of characteristics such as elasticity, light weight, rapid pressure-sensitive fixation, easy use, flexible bending, ultra-thin volume, and reliable performance. By adding the foam layer 700, the interior decoration part can be made softer and more comfortable to touch.

[0105] like Fig.16 As shown, the foam layer 700 of the interior decoration part of the fourth embodiment can also be arranged between the functional layer 600 and the frame 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), and the second wire 410 of the temperature sensor 400 passes through the second through hole 710 and the first through hole 160 in sequence and is hidden in the B side of the frame 100.

[0106] It is understandable that a foam layer may be added on the basis of the interior parts of the first embodiment and the interior parts of the second embodiment. When the foam layer 700 is added on the basis of 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 on the basis of 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.

[0107] The interior decoration parts of the embodiment of the utility model can transfer heat to the outside through the heating of the heating layer 200, so as to realize rapid heating in the vehicle and improve the comfort of the passengers. The temperature can be monitored in real time by the temperature sensor 400 and the touch sensing signal of the sensing layer 500, so as to realize temperature control and avoid burns caused by the excessive temperature of the interior decoration parts when the passengers touch the surface of the interior decoration parts. The foam layer 700 can make the interior decoration parts soft and more comfortable.

[0108] Embodiment five:

[0109] like Fig.17A , Fig. 17B , Fig. 17C , Fig.17D and Fig.17E As shown, the fifth embodiment of the utility model provides an interior decoration part, which includes a skeleton 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, and a first wire 220 is connected to the welding point 211, thereby being electrically connected to the heating layer 200, and 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 is bendable, 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 from being exposed and affecting the appearance of the interior decoration part.

[0110] The heating layer 200 includes a plurality of heating units (for example, graphene heating units) 270. The first extension piece 210 is also provided with a heating unit 270. The heating units 270 are electrically connected to each other to achieve heating after power is turned on. The temperature sensor 400 is fixed on the first extension piece 210 and is bent to the B surface of the skeleton 100 along with the first extension piece 210 to achieve hiding. The temperature sensor 400 contacts the heating unit 270 on the first extension piece 210 to measure the temperature of the heating unit 270. The second wire 410 is connected to the temperature sensor 400 for powering on and / or transmitting electrical signals. By connecting the second wire 410 to a power source or a controller, the power supply and signal transmission of the temperature sensor 400 can be achieved. The welding point 211 is set on the heating unit 270 on the first extension piece 210. In this way, when the first wire 220 is connected to the power source, the heating unit 270 on the first extension piece 210 and the heating unit 270 on the heating layer 200 can be powered on, so that the heating layer 200 is heated.

[0111] The first wire 220 and the second wire 410 may be connected to a plug 280 , and the first wire 220 and the second wire 410 may be conveniently connected to a power source or a controller through the plug 280 .

[0112] The appearance layer 300 can cover the frame 100 and the heating layer 200 to hide the frame 100 and the heating layer 200, so that they cannot be seen, making the appearance of the interior decoration more beautiful. When covering, the appearance layer 300 can extend a preset length on the B side of the frame 100 to cover the welding point 211 and the temperature sensor 400 on the first extension piece 210, so that they cannot be seen on the B side of the frame 100, further hiding the welding point 211 and the temperature sensor 400, and improving the aesthetics of the interior decoration. Alternatively, the appearance layer 300 may not cover the welding point 211 and the temperature sensor 400, but cover the welding point 211 and the temperature sensor through the counterpart of the interior decoration to achieve an aesthetic effect.

[0113] The interior decoration part of the fifth embodiment of the utility model realizes the connection between the first wire 210 and the heating layer 200 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 decoration 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.

[0114] Embodiment six:

[0115] like Fig.18A , Fig.18B , Fig.18C , Fig.18DThe sixth embodiment of the present invention provides an interior decoration part, which has a structure substantially the same as that of the interior decoration part of the fifth embodiment, except that the structure of the frame 100 is different and the way in which the first extension piece 210 is bent to the B surface of the frame 100 is different. Specifically, in the sixth embodiment, Fig.18A As shown, the skeleton 100 is provided with a first through groove 181, 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 surface of the skeleton 100, and fits with the B surface of the skeleton 100. That is, the first extension piece 210 passes through the first through groove 181 and is reversed to the B surface of the skeleton 100, thereby hiding the welding point 211 and the temperature sensor 400; in this way, the first extension piece 210 can be prevented from being bent at the edge of the skeleton 100 and reversed to the B surface of the skeleton 100, so as to avoid the protrusion from damaging the first extension piece 210 when the edge of the skeleton 100 has a protrusion. For example, Fig.18B and Fig.18C As shown, a raised portion 100a may be provided at the edge of the skeleton 100. When a foam layer 700 is provided between the appearance layer 300 and the heating layer 200, the raised portion 100a may 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 method of the sixth embodiment of the utility model, 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.

[0116] After the first extension piece 210 is reversed from the first through groove 181 to the B surface 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, wherein 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.

[0117] like Fig.18D As shown, in some embodiments, the blocking cover 182 may not be provided on the frame 100, that is, after the first extension piece 210 is reversed from the first through groove 181 to the B surface of the frame 100, the blocking cover 182 is not used to fill the first through groove 181.

[0118] 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 may 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.

[0119] The interior decoration part of the sixth embodiment of the utility model is provided with a first through groove 181 on the frame 100, so that the first extension piece 210 passes through the first through groove 181 and is wrapped around the B surface of the frame 100, thereby preventing the first extension piece 210 from bending at the edge of the frame 100 and being wrapped around the B surface of the frame 100, thereby preventing the protrusion from causing damage to the first extension piece 210 when there is a protrusion on the edge of the frame 100.

[0120] Embodiment seven:

The structure of the interior decoration part is basically the same as that of the fifth embodiment, except that: the heating unit 270 is not arranged on the first extension piece 210, and the temperature sensor 400 is not arranged on the first extension piece 210, but a second through groove 190 is opened on the frame 100, and the temperature sensor 400 is stuck in the second through groove 190 and contacts the heating unit 270 on the heating layer 200, so as to measure the temperature of the heating layer 200, and the second wire 410 on the temperature sensor 400 passes through the second through groove 190 and reaches the B surface of the frame 100 to achieve hiding. That is, in the seventh embodiment, the welding point 211 is hidden by the first extension piece 210 being reversed to the B surface of the frame 100, and the second wire 410 passes through the second through groove 190 to reach the B surface of the frame 100 to achieve hiding. Similar to the fifth embodiment, the first wire 210 is connected to the soldering point 211 , and the first wire 210 and the second wire 220 can be connected to the plug 280 .

[0122] like Fig.19C and Fig.19D As shown, 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, so that the temperature of the heating layer 200 can be detected by the probe 430.

[0123] In the interior decoration part of the seventh embodiment of the utility model, 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 surface of the skeleton 100 to achieve concealment, making the interior decoration part more beautiful.
