Description

Technical Field

[0001] The utility model relates to the field of automobile parts, in particular to a seat ventilation structure. Background Art

[0002] In order to obtain a better driving and riding experience, many existing automobile seats have added a massage function. In order to improve the massage experience, many current automobile seat manufacturers are considering changing the massage component of the seat back from pneumatic massage to mechanical massage, which brings great challenges to the layout of the ventilation system. In order to balance the ventilation performance and not reduce the performance of mechanical massage, a special airbag design is needed.

[0003] The technical problem to be solved by this application is: how to design a seat ventilation structure that can adapt to the mechanical massage solution. Summary of the Invention

[0004] In order to overcome the deficiencies of the prior art, the purpose of the utility model is to provide a seat ventilation structure.

[0005] The technical solution adopted by the utility model is: a seat ventilation structure, including an air duct structure, a connection channel and a ventilation fan. The ventilation fan is connected to the air duct structure through the connection channel. The air duct structure includes an assembly surface, a support grid pad and a sealing layer. The support grid pad is used to support the ventilation air duct formed by the assembly surface and the sealing layer. The ventilation air duct includes a main air duct and a side air duct. A massage channel allowing the operation of a mechanical massage mechanism is provided between the main air duct and the side air duct.

[0006] In some embodiments, the ventilation air duct includes an air inlet duct, which is arranged above the main air duct and the side air duct and is connected to the main air duct and the side air duct. One end of the connection channel is connected to the ventilation fan, and the other end is connected to the air inlet duct.

[0007] In some embodiments, the air duct structure includes an air inlet grid pad, which is arranged at the air inlet duct and the connection position between the air inlet duct and the side air duct.

[0008] In some embodiments, the air inlet grid pad is arranged between the support grid pad and the sealing layer.

[0009] In some embodiments, the assembly surface is provided with a plurality of ventilation holes communicated with the air outlet holes of the seat foam, and the assembly surface is fixedly connected to the seat foam body.

[0010] In some embodiments, the connection channel is made of soft rubber material and is fixedly connected to the sealing layer. The connection channel is connected to the ventilation fan by a snap connection. [[ID=3S]]

[0011] In some embodiments, the shape of the ventilation air duct is set to be an inverted "mountain" shape from top to bottom, and the shape of the air inlet grid pad is set to be a "ㄇ" shape.

[0012] In some implementations, the width of the main air duct is greater than the width of the side air ducts but less than twice the width of the side air ducts.

[0013] The beneficial effects of this utility model are as follows:

[0014] This type of seat ventilation structure uses an irregularly shaped ventilation duct to avoid the travel range of the mechanical massage mechanism, thus maximizing the performance of the mechanical massage while ensuring the ventilation performance of the backrest. In addition, a double-layer mesh pad is used to widen the relatively narrow side channels in the ventilation duct, making the airflow of the air bag more uniform. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1 This utility model provides a technical solution: a seat ventilation structure, including an air duct structure 1, a connecting channel 2 and a ventilation fan 3, wherein the ventilation fan 3 is connected to the air duct structure 1 through the connecting channel 2.

[0020] The air duct structure 1 includes an assembly surface 11, a supporting mesh pad 12, and a sealing layer 13. The outer edges of the assembly surface 11 and the outer edges of the sealing layer 13 are fixedly connected, and the two form a ventilation air duct 10 in which gas can flow. The assembly surface 11 and the sealing layer 13 are both made of non-woven fabric, which ensures that the air duct formed by the assembly surface 11 and the sealing layer 13 has good sealing performance.

[0021] The assembly surface 11 is provided with several ventilation holes that communicate with the air outlet holes of the seat foam. The assembly surface 11 is fixedly connected to the seat foam body.

[0022] Please see Figure 1 and Figure 2 A support grid pad 12 is disposed between the assembly surface 11 and the sealing layer 13. The support grid pad 12 is used to support the ventilation duct 10 formed by the assembly surface 11 and the sealing layer 13 and to ensure that the gas in the ventilation duct 10 can flow normally, ensuring support performance and gas flow performance. The ventilation duct 10 includes an air inlet duct 101, a main air duct 102 and a side air duct 103. The two side air ducts 103 are respectively disposed on both sides of the main air duct 102. A massage channel 104 is provided between the main air duct 102 and the side air ducts 103 to allow the operation of the mechanical massage mechanism. The width of the main air duct 102 is greater than the width of the side air duct 103 but less than twice the width of the side air duct 103, widening the narrow side air ducts 103, so that the airflow to the main air duct 102 and the side air ducts 103 is more uniform. An air inlet duct 101 is positioned above the main air duct 102 and the side air duct 103, and is connected to both. A connecting channel 2 is connected at one end to a ventilation fan 3 and at the other end to the air inlet duct 101. The connecting channel 2 is made of soft rubber and is fixedly connected to the sealing layer 13 by adhesive or stitching. The connecting channel 2 is connected to the ventilation fan 3 by a snap-fit ​​connection. The sealing layer 13 has air inlet holes, and the connecting channel 2 is connected to the air inlet duct 101 through these holes. The ventilation fan 3 is connected to the air inlet duct 101 through the connecting channel 2.

[0023] To better guide the air to the side duct 103, the duct structure 1 includes an air inlet mesh pad 14. The air inlet mesh pad 14 is disposed in the air inlet duct 101 and at the connection position between the air inlet duct 101 and the side duct 103. The air inlet mesh pad 14 is disposed between the support mesh pad 12 and the sealing layer 13. The air inlet mesh pad 14 can better support the connection position between the air inlet duct 101 and the side duct 103, so that after the ventilation fan 3 enters the air inlet duct 101, the air is more easily diverted to the side duct 103, ensuring the airflow into the side duct 103.

[0024] Due to the limitations of the foam structure and mechanical massage area, the side air duct 103 is narrower than the main air duct 102. After adding the air inlet mesh pad 14, the air inlet cross-sectional area of ​​the side air duct 103 increases, becoming similar to the cross-sectional area of ​​the middle channel, resulting in a more uniform airflow distribution between the main air duct 102 and the side air duct 103.

[0025] Based on the current operating trajectory of the mechanical massage mechanism, the overall shape of the ventilation duct 10 is set to an inverted "mountain" shape from top to bottom, and the shape of the air inlet mesh pad 14 is set to "U".

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