[0035] Example 1

[0036] This embodiment provides a combined self-heating car seat cushion, comprising:

[0037] A car seat body, wherein the car seat body is provided with a power port 104 and a controller 103;

[0038] The headrest cushion 1, backrest cushion 3, seat cushion 5, and foot pad 7 are connected in series via connecting line 2. Each of the headrest cushion 1, backrest cushion 3, seat cushion 5, and foot pad 7 includes a heating filling layer 9. The heating filling layer 9 includes a heating layer 92 and multiple interlayers connected together. The heating layer 92 is disposed between the interlayers. The heating layer 92 has a carbon nanotube far-infrared paper layer 923, which is connected in series with the power port.

[0039] The power converter 10 is fixedly installed on the main body of the car seat. The power converter 10 is electrically connected to the power port and the controller and is used to switch the working voltage of the carbon nanotube far-infrared paper layer 923. The controller is used to control the voltage input to the car seat cushion. The power interface 104 adopts a 12V round interface, which can be adapted to most common interfaces on cars.

[0040] It should be noted that the carbon nanotube far-infrared paper layer 923 is composed of multiple carbon nanotube far-infrared papers stacked together. The working voltage range of the carbon nanotube far-infrared paper layer 923 is 5V to 24V, and the appropriate heating level can be selected according to the external ambient temperature, ensuring the rapid heating capability of the heating layer.

[0041] It should be noted that the headrest cushion 1, the backrest cushion 3, and the seat cushion 5 also include:

[0042] The support layer 8 is used to be installed and attached to the main body of the car seat. In this embodiment, the support layer 8 is composed of fabric and rigid plastic.

[0043] The heating filling layer 9 is connected to the support layer 8. The heating filling layer 9 includes a breathable layer 91, a heating layer 92, a first filling layer 93, and a support layer 94 that are fixedly connected in sequence. The support layer 94 is close to the surface of the support layer 8. The breathable layer 91 has multiple micro springs built in, and the micro springs are arranged in a rectangular array. The first filling layer 93 is a sponge layer, and the support layer 94 is formed by multiple spring arrays to ensure the comfort and resilience of the car seat cushion and to ensure the heating of the gas and objects in the local space.

[0044] It should be noted that the heating layers of the headrest 1, backrest 3, seat cushion 5, and foot pad 7 are all connected to the power port via wires. It is worth mentioning that the heating layer of the foot pad 7 can be connected to the seat cushion 5 via a circular power interface, or it can be connected to the power supply port on the car.

[0045] Furthermore, in this embodiment, the support layer 8 is mainly composed of a skin-friendly layer 81 and a rigid support layer 82, wherein the skin-friendly layer 81 is a leather layer, and the rigid support layer 82 is a frame structure composed of a steel frame or plastic frame and a mesh fabric; so as to ensure that the surface of the car seat cushion has a certain degree of wear resistance, water resistance and structural stability.

[0046] It should be noted that the foot pad 7 further includes a filamentous layer 71, a toughness layer 72, a second filling layer 73, an absorbent layer 74, and an anti-slip layer 75, which are fixedly connected in sequence. The toughness layer 72 is made of the same material as the skin-friendly layer 81, and the heating layer 92 is disposed between the toughness layer 72 and the second filling layer 73. The filamentous layer 71 is a mesh formed by multiple filaments, and each filament is distributed interlaced on the surface of the toughness layer 72. The surface of the anti-slip layer 75 has several protrusions evenly distributed. In this embodiment, the filamentous layer 71 can also be a spiral structure.

[0047] In this embodiment, the floor mat 7 can be directly connected to the car interface via the floor mat power cord 6. The floor mat power cord 6 can be organized using the cable organizer 76 to improve cleanliness during use. The floor mat 7 can input 12V voltage and can provide rapid auxiliary heating for the bottom of the car interior. When combined with the seat cushion, it can create a comfortable local environment for the human body.

[0048] It should be noted that the heating layer 92 includes a tough layer 921, a first waterproof layer 922, a carbon nanotube far-infrared paper layer 923, a second waterproof layer 924, a reflective layer 925, and a heat insulation layer 926 arranged sequentially. The first waterproof layer 922 and the second waterproof layer 924 are respectively bonded to the two surfaces of the carbon nanotube far-infrared paper layer 923. The tough layer 921, the carbon nanotube far-infrared paper layer 923, the reflective layer 924, and the heat insulation layer 925 are connected by machine stitching. The first waterproof layer 922 and the second waterproof layer 924 are made of the same material, have the same structure, and are symmetrical about the carbon nanotube far-infrared paper layer 923.

[0049] This not only extends the lifespan of the heating layer but also improves production efficiency. In this embodiment, the electrothermal conversion efficiency of the heating layer 92 can reach 99.5%, which is at least 30% higher than that of traditional components such as ceramics, resistance wires, carbon fibers, graphene, and PCT.

[0050] When the power port 104 is connected to a power source, the controller 103 controls the power converter 10 to output a voltage between 5V and 24V. When a 5V voltage is input, the heating layer 92 is powered on and begins to heat up, emitting far-infrared rays to distribute the heat evenly from the tough layer 921 and the first waterproof layer 922. First, the air inside the pores of the breathable layer 921 is warmed and the heat is evenly distributed, and then the heat is distributed outwards. When the user uses the product, the warm air from the breathable layer 921 is released to the outside by squeezing, resulting in rapid localized heating. The area in contact between the user and the car seat cushion will quickly heat up to a warm state. The heating area is concentrated at the point of direct contact between the user and the car seat cushion, ensuring that the user can continuously receive the heat emitted by the car seat cushion during use.
