[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution for a ventilation system for automobile seats: A ventilation system for automobile seats includes an integrally connected ventilation frame 1, a seat cushion ventilation frame 2, and a backrest ventilation frame 3. The ventilation frame 1 and the seat cushion ventilation frame 2 are fixedly connected, and the seat cushion ventilation frame 2 and the backrest ventilation frame 3 are rotatably connected. The ventilation frame 1 and the seat cushion ventilation frame 2 are interconnected, and the seat cushion ventilation frame 2 and the backrest ventilation frame 3 are rotatably connected through a rotating seat 5. By setting the rotating seat 5 between the seat cushion ventilation frame 2 and the backrest ventilation frame 3, it can serve as a rotating shaft component, allowing the backrest ventilation frame 3 to rotate along the seat cushion ventilation frame 2, thereby ensuring that the seat backrest maintains its adjustability.

[0025] The back panel of the seat cushion ventilation frame 2 has a ventilation opening A11, and the bottom plate of the backrest ventilation frame 3 has a ventilation opening B12. Ventilation openings A11 and B12 are connected by a ventilation cover 6. The ventilation cover 6 is a bellows structure and covers the outside of the flexible conduit 10. By using the ventilation cover 6, the seat cushion ventilation frame 2 and the backrest ventilation frame 3 are kept in a conductive state so that the ventilation fan 4 can blow air to the whole structure to exhaust cold / heat. The bellows structure of the ventilation cover 6 has good bending performance and can bend synchronously with the adjustment of the seat back to ensure smooth cold / heat ventilation.

[0026] The frame panel of the ventilation rack 1 is equipped with multiple ventilation fans 4. The support of the ventilation rack 1 is equipped with a filter plate 7. The filter plate 7 has two sets of filter plates, and the two sets of filter plates are stainless steel filter and HEPA filter in sequence along the ventilation direction of the ventilation fan 4. By setting the filter plate 7 in the form of a combination of stainless steel filter and HEPA filter inside the ventilation rack 1, the air blown by the ventilation fan 4 can be filtered and dust removed, and dust can be prevented from adhering to the inside of the ventilation system.

[0027] The seat cushion ventilation frame 2 has a first heat exchange coil 8 inside its support, and the back ventilation frame 3 has a second heat exchange coil 9 inside its support. The first heat exchange coil 8 and the second heat exchange coil 9 are connected by a flexible conduit 10. Both the first heat exchange coil 8 and the second heat exchange coil 9 are U-shaped coil structures. By setting the first heat exchange coil 8 inside the seat cushion ventilation frame 2 and the second heat exchange coil 9 inside the back ventilation frame 3, they serve as ventilation and cooling / heating components, providing ventilation capacity for the overall structure of the car seat and improving the comprehensiveness and comfort of seat ventilation. Furthermore, by utilizing the connection between the first heat exchange coil 8, the flexible conduit 10, and the second heat exchange coil 9, an integrated conductive state is formed, which transports and conducts the cold / heat generated by the compression and condensation components in the car engine compartment, providing cold / heat ventilation for the car seat.

[0028] One end of the pipeline of the first heat exchange coil 8 is equipped with a flow valve port A13, and the other end of the pipeline of the first heat exchange coil 8 is equipped with a flow valve port B14. By using the flow valve port A13 and the flow valve port B14 as the medium inlet and outlet, they are connected to the compression and condensation components in the engine compartment of the car to form a dynamic circulation state and circulate the cooling / heating medium.

[0029] The seat cushion ventilation frame 2 has a ventilation mesh plate A21 on its seat cushion panel, and the backrest ventilation frame 3 has a ventilation mesh plate B31 on its backrest panel. Both ventilation mesh plates A21 and B31 are perforated plate structures. By setting ventilation mesh plates A21 on the seat cushion ventilation frame 2 and B31 on the backrest ventilation frame 3 as ventilation hole components, cold / heat is conducted out to provide cooling / heating for the car seat and improve the comfort of the car seat.

[0030] The working principle of this utility model is as follows: When adding a ventilation system inside a car seat, the seat cushion ventilation frame 2 and the backrest ventilation frame 3 are sequentially installed inside the seat cushion and backrest of the car seat, and the ventilation fan 4 of the ventilation frame 1 extends into the driver's cabin. At the same time as installation, based on the rotational transmission of the rotating seat 5, as a rotating shaft component, the backrest ventilation frame 3 can rotate along the seat cushion ventilation frame 2 to ensure that the seat backrest maintains its adjustment capability. Then, based on the combination of the connecting valve port A13 and the connecting valve port B14, as the medium inlet and outlet, it is connected to the compression and condensation component in the car engine compartment to form a dynamic circulation state, so as to circulate the cooling / heating medium.

[0031] During subsequent ventilation and cooling / heating operations for the car seats, the cooling / heating medium from the compressed condensing components in the car engine compartment is diverted and transported to the seat ventilation frame 2 and the back ventilation frame 3 through the connection of the first heat exchange coil 8, the connecting hose 10, and the second heat exchange coil 9. At the same time, the air is blown by the ventilation fan 4 into the seat ventilation frame 2 and into the back ventilation frame 3 under the guidance of the ventilation hood 6, carrying away the cold / heat in the two sets of heat exchange coils. The cold / heat air is then blown out through the ventilation mesh A21 on the seat ventilation frame 2 and the ventilation mesh B31 on the back ventilation frame 3, circulating to the outside of the seat, providing comprehensive ventilation, cooling, and heating functions for the passengers.

[0032] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
