[0002] A car seat is a seat with a backrest for passengers to sit on. It is integrated with the vehicle structure or has a split design. A car seat is usually composed of a surface cover, internal foam material, a frame, adjustment devices and connectors. The ventilation and heating assembly is an important component to improve seat comfort. Its function is to provide passengers with a suitable temperature and airflow environment under different climatic conditions, and to perform cooling and heating functions.

[0003] In the prior art, part of the seat ventilation function is achieved through a built-in fan, which can absorb the airflow in the cabin and guide it to the upper layer of the seat through a pipe, and then flow out through the air vents. However, the cooling speed of the seat is slow when relying solely on the fan, especially in hot summer. The temperature in the car is very high. It may be difficult to quickly reduce the temperature of the seat surface by relying solely on the fan, which reduces the heat dissipation efficiency. Therefore, in view of the above shortcomings, a car seat heating and ventilation assembly is proposed to solve the above problems. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 2 and Figure 4 The utility model provides an embodiment: a car seat heating and ventilation assembly, including a fixing plate 1, a heating component is arranged on the top of the fixing plate 1, and the heating component includes two ECU control modules 2. When the seat needs to be heated, these ECU control modules 2 will generate heat, thereby heating the surface of the seat. The bottom ends of multiple ECU control modules 2 are arranged on the top of the fixing plate 1, and the front side of the fixing plate 1 is fixedly connected with a mounting frame 3, and the four corners of the mounting frame 3 are internally threaded with bolts 5. The mounting frame 3 and the fixing plate 1 can be firmly connected together through these bolts 5. The external threads of multiple bolts 5 are connected to the front side of the fixing plate 1, and the interior of the mounting frame 3 is rotatably connected with a fan 4 to generate airflow for ventilation.

[0024] Reference Figure 1 , Figure 3 and Figure 5 Two through holes 6 are provided inside the fixing plate 1. These holes allow air to circulate to promote the ventilation effect of the seat. A fixing frame 7 is fixedly connected to the rear end of the fixing plate 1. A plurality of clamping blocks 8 are fixedly connected to the front side of the fixing frame 7. A coolant pipe 9 is fixedly connected to the inside of the plurality of clamping blocks 8. When the airflow sucked by the fan 4 passes through the coolant pipe 9, it will take away the heat from the surface of the seat, thereby achieving a cooling effect. A protective plate 10 is fixedly connected to the rear side of the fixing frame 7. The material of the protective plate 10 is a fiber material that can provide a certain structural strength. The material of the clamping block 8 is a plastic material with a certain elasticity, which is convenient for replacing the coolant pipe 9. A plurality of filter holes 11 are provided inside the protective plate 10. In order to filter out dust and other impurities in the inhaled air and ensure that the air entering the seat is clean, a plurality of heating wires 12 are arranged inside the fixed plate 1. The heating wire 12 is composed of a plurality of insulating heating wires and an insulating layer coated on the outside of the insulating heating wire to ensure its high temperature resistance. The insulating heating wire helps to maintain the heating efficiency during the heating process and avoid damage to the surrounding environment. The insulating layer is coated on the outside of the insulating heating wire to isolate the heating wire from the external environment to ensure safety and insulation performance. A temperature sensor 13 is arranged inside the fixed plate 1 to monitor the temperature of the heating wire 12. The ECU control module 2 is connected to the heating wire 12 by an electric wire.

[0025] Working principle: When the fan 4 needs to be replaced, you only need to tighten the bolt 5. By tightening it, the installation frame 3 can drive the fan 4 to be taken out and replaced. Then, during the movement, the wind will be sucked into the inside of the fixed plate 1 under the action of the fan 4. In this process, it will first pass through the protective plate 10 and the filter hole 11 to filter out dust and impurities, and then pass through the outside of the coolant pipe 9 to absorb the cold air emitted by the coolant pipe 9, and then drive the cold air to be transmitted from the inside of the through hole 6, and then ventilate and dissipate the heat from the inside of the fan 4. Then, when the coolant pipe 9 needs to be replaced, you only need to remove it from the inside of the clamping block 8. Because the clamping block 8 is made of plastic material and is elastic, the coolant pipe 9 can be easily taken out or put in, and the ECU control module 2 is designed to be started when the customer needs it to heat the seat.

[0026] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
