Description

Technical Field

[0001] This application relates to the field of seat ventilation, and in particular to a novel seat air intake system. Background Technology

[0002] With the continuous development of the automotive industry, the comfort and functionality of car seats are receiving increasing attention. As a key component for improving car seat comfort, the performance and quality of the ventilation system directly impact the passenger experience. An efficient and stable ventilation system can effectively regulate airflow over the seat surface, removing heat and moisture generated by the contact between the body and the seat, creating a more comfortable riding environment for passengers. This is of great significance for improving the overall quality and market competitiveness of a vehicle.

[0003] In existing automotive seat ventilation systems, traditional solutions typically employ a structure consisting of a ventilation bag, a fan, and mounting hardware. The ventilation bag is generally made of tape, PU film, 3D fabric, or non-woven fabric. In actual production, the ventilation bag involves multiple processes, including cutting, welding, and adhesive application. During installation, the ventilation bag must be aligned with the perforations in the foam. These steps are all designed to create a complete ventilation path, allowing the fan to deliver air through the ventilation bag to the seat surface, thus achieving ventilation.

[0004] However, the complex structure of ventilation bags involves multiple materials and processes, resulting in high material and manufacturing costs. Aligning the ventilation bags with the foam through-holes during installation is challenging, impacting installation efficiency. Furthermore, the thickness of the ventilation bags increases the space required for the product. Additionally, the cutting of 3D fabric generates debris, which can enter the fan during operation, causing noise and reducing airflow. Utility Model Content

[0005] To reduce material, structural, and process costs, this application provides a novel seat ventilation system.

[0006] The novel seat ventilation system provided in this application adopts the following technical solution:

[0007] A novel seat ventilation system includes a foam component, a sealing plate, and a fan.

[0009] The sealing plate is connected to the foam component, the sealing plate covers the ventilation groove, and the sealing plate is provided with ventilation openings.

[0010] The fan is connected to the sealing plate and is located at the vent.

[0011] By adopting the above technical solutions, the ventilation bag is eliminated, thereby reducing material, structural and process costs, shrinking product size and reducing ventilation resistance; since the sealing plate is installed on the entire surface, there is no need for hole alignment, thereby reducing installation difficulty and increasing installation speed.

[0012] Preferably, the sealing plate includes a felt plate.

[0023] By adopting the above technical solution, installation is convenient using adhesive tape or spray adhesive.

[0024] Preferably, it also includes rubber nails,

[0032] Preferably, the fan includes a vortex fan or a butterfly fan.

[0033] By adopting the above technical solution, the gas flow can be driven to achieve ventilation.

[0044] The present application will be further described in detail below with reference to the accompanying drawings.

[0045] Reference Figure 1 and Figure 2This application discloses a novel seat ventilation system, including a foam component 1.

[0046] It should be noted that: side A of foam component 1 is used to support the human body, and the back of side A is side B; for example, if foam component 1 in the attached figure is used to form a backrest, then side A of foam component 1 is used to support the back of the human body; if foam component 1 is used to form a chair seat, then side A of foam component 1 is used to support the buttocks, thighs, etc. of the human body.

[0047] The foam component 1 has a ventilation groove 11 on its B side, and a ventilation hole 12 at the bottom of the ventilation groove 11, which penetrates the A side of the foam component 1. The ventilation groove 11 can be straight, curved, or grid-shaped, etc., and the specific shape can be selected according to the actual ventilation requirements and the design of the seat. The size and number of ventilation holes 12 will also be reasonably designed according to the ventilation requirements.

[0048] Reference Figure 3 and Figure 4 A novel seat ventilation system also includes a sealing plate 2 and a fan 3.

[0049] A sealing plate 2 is connected to the foam component 1, and the sealing plate 2 covers the ventilation groove 11. The sealing plate 2 is provided with a ventilation opening 21. A fan 3 is connected to the sealing plate 2, and the fan 3 is located at the ventilation opening 21. The fan 3 is located on the side of the sealing plate 2 away from the foam component 1.

[0050] The sealing plate 2 includes a felt board 22 and a fixing plate 23. The felt board 22 is formed by high-temperature hot pressing and can be conformally molded to the B side of the foam component 1, making installation convenient and leak-free. The felt board 22 is adhered to the foam component 1 and covers the opening of the ventilation groove 11. The fixing plate 23 is adhered to the side of the felt board 22 facing the foam component 1. The ventilation opening 21 passes through the felt board 22 and the fixing plate 23; the ventilation opening 21 is connected to the opening of the ventilation groove 11. In one embodiment, the fixing plate 23 may include a PP board.

[0051] The felt board 22 and the foam component 1 can be fixed using double-sided tape or spray adhesive. Double-sided tape has the advantages of easy application and good fixing effect. During installation, simply stick the double-sided tape to the contact surfaces of the felt board 22 and the foam component 1, and then attach them together. Spray adhesive fixing is performed at the seat factory. Adhesive is evenly sprayed onto the surface of the felt board 22 or the foam component 1 using a spray gun, and then the two are attached together. The amount and distribution of adhesive can be flexibly adjusted according to the actual situation to ensure a good fixing effect.

[0052] Reference Figure 4 and Figure 5The fan 3 can be either a vortex fan 3 or a butterfly fan 3. The vortex fan 3 is characterized by its high airflow and efficiency, making it suitable for applications requiring high ventilation. The butterfly fan 3, on the other hand, is characterized by its small size and low noise, making it suitable for environments with strict requirements on space and noise levels.

[0053] The fan 3 includes a housing 31, a connecting block 32, and a locking block 33. It should be noted that the fan blades, motor, and other structures of the fan 3 are not shown in the figure.

[0054] The housing 31 is used to abut against the surface of the felt plate 22 facing away from the fixing plate 23. A connecting block 32 is fixedly connected to the surface of the housing 31 facing the felt plate 22, and extends through the vent 21. A locking block 33 is connected to the connecting block 32, with a gap between the locking block 33 and the housing 31. The surface of the locking block 33 facing the housing 31 abuts against the surface of the fixing plate 23 facing away from the felt plate 22. Simultaneously, a guide surface 331 is provided on the surface of the locking block 33 facing away from the housing 31, and the guide surface 331 abuts against the edge of the vent 21. In the attached diagram: four connecting blocks 32 are provided, evenly spaced along the circumference of the housing 31. The locking blocks 33 correspond one-to-one with the connecting blocks 32, and are located on the side of the connecting block 32 facing away from the center of the housing 31. The distance from any point on the guide surface 331 to the housing 31 decreases as that point moves away from the center of the housing 31.

[0055] A novel seat suction system also includes rubber nails 4. The sealing plate 2 has a pre-drilled opening 24 that passes through the felt plate 22 and the fixing plate 23, for mounting the rubber nails 4. The housing 31 also has an mounting opening 311 for mounting the rubber nails 4.

[0056] In the attached diagram: There are four reserved openings 24, which are evenly distributed along the circumference of the housing 31; along the circumference of the housing 31: any reserved opening 24 is located between adjacent connecting blocks 32, and any connecting block 32 is located between adjacent reserved openings 24.

[0057] The implementation principle of a novel seat ventilation system in this application embodiment is as follows: The ventilation bag is eliminated and replaced with a felt board 22, reducing material, structural, and process costs. The felt board 22 is formed by high-temperature hot pressing and can be molded to conform to the shape of the B-side of the foam part 1, making installation convenient and eliminating the need for hole alignment, thus reducing installation difficulty and increasing installation speed. Simultaneously, eliminating the ventilation bag reduces the product's volume, lowers ventilation resistance, and increases ventilation volume. The use of rubber nails 4 reduces vibration and noise during fan 3 operation, minimizing system noise. Furthermore, the PP board increases the stability of fan 3, ensuring the reliability and stability of the system.

[0058] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
