Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to an integrated ventilation structure for automotive seats that combines suction and blowing. Background Technology

[0002] With the continuous development of automotive technology, users are spending more and more time inside their cars, and the concept of treating the car as a home is gradually gaining acceptance. Creating a more comfortable driving environment, especially in the hot summer months, and effectively cooling the areas where the body contacts the car seats, is a growing concern. Traditional automotive ventilation systems use a single ventilation method, either a blowing system or a suction system, which cannot meet the diverse application needs of customers. Therefore, an integrated blowing and suction ventilation solution is needed to address customers' needs for rapid cooling and prolonged use, while simultaneously enhancing product competitiveness. Utility Model Content

[0003] This utility model provides an integrated ventilation structure for car seats that combines suction and blowing, in order to solve the technical problems mentioned in the background art.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0005] The integrated ventilation structure for car seats includes:

[0006] Seat foam, wherein the seat foam is fixed to a car seat;

[0007] A ventilation bag is provided on one side of the seat foam; an air inlet is provided on the side of the ventilation bag away from the seat foam, and multiple air outlets are provided on the side of the ventilation bag close to the seat foam; multiple air ducts communicating with the air outlets are provided inside the seat foam.

[0008] A suction and blowing assembly includes an active fan and a passive fan; the active fan is located inside the ventilation bag and near the air inlet, and blows air into the ventilation bag; the passive fan is located outside the ventilation bag and near the air inlet, and draws air from the ventilation bag.

[0009] As a further preferred embodiment of this utility model, the air inlet is located on the central axis of the ventilation bag, the active fan blows air into the ventilation bag, the air flows to both sides to form an airflow, and the airflow flows through the air outlet to the air duct inside the seat foam.

[0010] As a further preferred embodiment of this invention, the number of air outlets is the same as the number of air ducts.

[0011] As a further preferred embodiment of this invention, the active fan is a backward centrifugal fan or a forward centrifugal dual-outlet fan.

[0012] As a further preferred embodiment of this invention, the passive fan is a forward centrifugal single-outlet fan or a forward centrifugal double-outlet fan.

[0013] Compared with the prior art, the present invention has the following advantages or beneficial effects:

[0014] This invention employs an integrated suction and blowing ventilation structure: an active fan blows air into the ventilation bag, creating an airflow that flows through the outlet to the air duct, thus achieving a blowing effect on the seat. Multiple outlets and air ducts are provided, allowing for greater airflow and ensuring 360° airflow uniformity. A passive fan draws air from the air duct into the ventilation bag and exhausts it through the inlet, achieving a suction effect on the seat. This integrated suction and blowing ventilation method achieves rapid cooling, expanding the application of ventilated seats and providing end-users with a richer driving and riding experience. The passive fan uses a forward centrifugal fan with strong load-bearing capacity. Attached Figure Description

[0023] It should be noted that the terms "part," "other," "first," "second," etc., used in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0024] Please refer to the appendix. Figures 1-3 This embodiment provides an integrated ventilation structure for a car seat, including a seat foam 1, a ventilation bag 2, and a suction and blowing assembly 3. The seat foam is fixed to the car seat. Multiple air ducts 11 are provided inside the seat foam 1. The ventilation bag 2 is located on one side of the seat foam 1, and multiple air outlets 22 are provided on the side of the ventilation bag 2 closest to the seat foam 1, with the air outlets 22 communicating with the air ducts 11. An air inlet 21 is provided on the side of the ventilation bag 2 furthest from the seat foam 1. The suction and blowing assembly 3 includes an active fan 31 and a passive fan 32. The active fan 31 is located inside the ventilation bag 2 and near the air inlet 21, blowing air into the ventilation bag 2. The passive fan 32 is located outside the ventilation bag 2 and near the air inlet 21, drawing air from the ventilation bag 2.

[0025] To further explain, the air inlet 21 is located on the central axis of the ventilation bag 2, and there are multiple air outlets 22. The number of air ducts 11 is the same as that of the air outlets 22. This design can provide more airflow and achieve 360° air outlet to ensure uniform ventilation.

[0026] As attached Figure 4 , 5 As shown, the above embodiments have the following two operating modes:

[0027] Air blowing mode: The active fan 31 is working, while the impeller of the passive fan 32 is locked and does not rotate or rotates with the wind. The rotation of the impeller of the active fan 31 causes air to enter the air bag through the air inlet 21 and then flow to both sides to form an airflow. This airflow flows into the air duct 11 through the air outlet 22 and is blown out, achieving the air blowing effect on the seat.

[0028] Suction mode: Passive fan 32 operates, while the impeller of active fan 31 is locked or rotates with the wind. Airflow, driven by the rotation of the impeller of passive fan 32, flows from air duct 11 into the air bag and exits from air inlet 21, achieving the suction effect on the seat.

[0029] This embodiment uses an integrated suction and blowing ventilation method to achieve rapid cooling. By expanding the application of ventilated seats, it brings a richer driving and riding experience to end customers.

[0030] In addition to the embodiments described above, this utility model may have other implementations. All technical solutions formed by equivalent substitution or equivalent transformation fall within the protection scope claimed by this utility model.
