Using the above technical solution, the first flexible backrest layer 6 covers the hot water pipe 5, and the hot water pipe 5 and the first flexible backrest layer 6 can form an integral structure that can be installed as a whole in the seat backrest 2, which is convenient for installation. Furthermore, the first flexible backrest layer 6 can also limit the position of the hot water pipe 5, preventing it from shifting.
[0032] As a preferred example, the first backrest flexible layer 6 is a second foamed sponge layer with a second thermally conductive reinforcing filler added. The second foamed sponge layer ensures the softness and comfort of the seat back 2.
[0033] In practice, the second foamed sponge layer can be made of memory foam. The hot water pipe 5 on the backrest and the second foamed sponge layer can be integrated through a composite molding process.
[0034] In some embodiments, the seat cushion 1 is provided with a second cushion flexible layer 16 containing a third thermally conductive reinforcing filler, and the second cushion flexible layer 16 covers the side of the first cushion flexible layer 4 adjacent to the seat cushion cover 17 of the seat cushion 1. By providing a second cushion flexible layer 16 with a third thermally conductive reinforcing filler, different materials can be used to manufacture the first cushion flexible layer 4 and the second cushion flexible layer 16, which helps to improve the comfort of the seat cushion 1.
[0035] As a preferred example, the second cushion flexible layer 16 includes a first cotton layer with a third thermally conductive reinforcing filler. The first cotton layer increases the softness and comfort of the seat cushion 1, providing a more delicate tactile experience for the user. In practice, the first cotton layer is attached to the inner side of the seat cushion cover 17.
[0036] As a preferred example, the first cushion flexible layer 4, the second cushion flexible layer 16, and the cushion cover 17 are stacked sequentially from the inside to the outside.
[0037] In some embodiments, a second flexible backrest layer 18 with a fourth thermally conductive reinforcing filler is provided inside the seat backrest 2, and the second flexible backrest layer 18 covers the side of the first flexible backrest layer 6 that is adjacent to the backrest cover 19 of the seat backrest 2. By providing a second flexible backrest layer 18 with a fourth thermally conductive reinforcing filler, different materials can be used to manufacture the first flexible backrest layer 6 and the second flexible backrest layer 18, thereby improving the comfort of the seat backrest 2.
[0038] As a preferred example, the second backrest flexible layer 18 includes a second cotton layer with a fourth thermally conductive reinforcing filler.

[0040] As a specific example, at least one of the first, second, third, and fourth thermally conductive reinforcing fillers comprises metal powder and / or carbon fiber. Using metal powder and / or carbon fiber as fillers can enhance thermal conductivity.
[0041] In some embodiments, the seat cushion 1's cushion cover 17 includes a first silicone leather layer, and the seat back 2's back cover 19 includes a second silicone leather layer. The silicone leather layer has good thermal conductivity, which helps improve the heat transfer performance of the vehicle seat, allowing users to feel temperature changes in the vehicle seat more quickly, thus enhancing the user experience of vehicle seats equipped with water heat exchange systems.
[0042] In some embodiments, a seat cushion hot water pipe 3 is provided inside the seat cushion 1, and a backrest hot water pipe 5 is provided inside the seat back 2. The seat cushion hot water pipe 3 and the backrest hot water pipe 5 are connected by an aluminum-plastic composite flexible hose. The aluminum-plastic composite flexible hose connects the seat cushion hot water pipe 3 and the backrest hot water pipe 5. The aluminum-plastic composite flexible hose has good bending performance and sealing performance, which can reduce the possibility of water leakage from the vehicle seat.
[0043] In practice, the aluminum-plastic composite hose and the seat cushion hot water pipe 3, as well as the aluminum-plastic composite hose and the backrest hot water pipe 5, are connected by heat fusion to ensure good sealing performance and prevent water leakage.
[0044] In some embodiments, the vehicle seat is also equipped with a water heater 7, a water tank 10, and a water pump 11. The hot water pipe 5 for the backrest, the hot water pipe 3 for the seat cushion, the water heater 7, the water tank 10, and the water pump 11 are connected in series through pipes to form a circulating water circuit. Integrating the water heater 7, water tank 10, and water pump 11 into the vehicle seat reduces the complexity of the vehicle seat's water heat exchange system, resulting in a simpler structure and more stable heating performance.
[0045] As a specific example, the water heat exchange system in a vehicle seat includes a water heater 7, a water tank 10, a water pump 11, two backrest hot water exchange pipes 5, two seat cushion hot water exchange pipes 3, two first connecting pipes 8, two second connecting pipes 9, a third connecting pipe 12, a fourth connecting pipe 13, and a fifth connecting pipe 14. The water heater 7 is installed on the seat cushion 1. One end of one seat cushion hot water exchange pipe 3 is connected to the input end of the water heater 7 via a first connecting pipe 8, and one end of the other seat cushion hot water exchange pipe 3 is connected to the output end of the water heater 7 via another first connecting pipe 8. The other end of one seat cushion hot water exchange pipe 3 is connected to one end of one backrest hot water exchange pipe 5 via a second connecting pipe 9, and the other end of the other seat cushion hot water exchange pipe 3 is connected to one end of the other backrest hot water exchange pipe 5 via another second connecting pipe 9. The water tank 10 and water pump 11 are installed on the seat back 2. The other end of one backrest hot water pipe 5, the third connecting pipe 12, the water tank 10, the fifth connecting pipe 14, the water pump 11, the fourth connecting pipe 13, and the other end of another backrest hot water pipe 5 are connected sequentially. The water heater 7, water tank 10, water pump 11, two backrest hot water pipes 5, two seat cushion hot water pipes 3, two first connecting pipes 8, two second connecting pipes 9, the third connecting pipe 12, the fourth connecting pipe 13, and the fifth connecting pipe 14 are connected to form a circulating water circuit, constituting a water heat exchange system. The second connecting pipe 9 can be an aluminum-plastic composite flexible hose.
[0046] In some embodiments, the vehicle seat also includes a switch 15, which controls the water heat exchange system to control the temperature of the vehicle seat. When the switch 15 is turned on, the water pump 11 and the water heater 7 start working simultaneously. The water pump 11 draws water from the water tank 10 to achieve water circulation. The circulating water is heated by the water heater 7, and the heat from the hot water in the seat cushion hot water pipe 3 and the backrest hot water pipe 5 can be used to heat the seat cushion 1 and the seat back 2.
[0047] Switch 15 can be mounted on the seat switch panel, and switch 15 can be a temperature control switch. The temperature control switch can turn the water pump 11 and water heater 7 on and off. At the same time, the temperature control switch can also control the temperature rise and fall of water heater 7, and can adjust the temperature of the vehicle seat between 10° and 35°.
[0048] In practical implementation, the seat cushion hot water pipe 3 and the backrest hot water pipe 5 can be set as curved and extended coils. The seat cushion hot water pipe 3 and the backrest hot water pipe 5 can be made of PE-RT pipe or PE-X pipe to ensure the heat resistance, flexibility and sealing performance of the seat cushion hot water pipe 3 and the backrest hot water pipe 5.
[0049] like Figure 3 As shown, the water reservoir 10 includes a reservoir body 20 and a reservoir lid 21. The reservoir body 20 is provided with a water outlet 23 and a water return outlet 22. After long-term use of the water heat exchange system, some water will evaporate and be lost. Water can be added by opening the reservoir lid 21. The reservoir body 20 can be made of a polypropylene / polyethylene blend.
