Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, and more specifically, relates to an air pipe anti-compression and air trapping structure. Background Technology

[0002] With the development of technology and people's increasing demands for travel comfort, lumbar support and massage have become an important factor for many consumers when purchasing a new car. As automotive intelligence rapidly advances, lumbar support and massage are gradually becoming standard features in automobiles.

[0003] For the lumbar support and massage system, a sub-assembly component, the comfort of the massage intensity is crucial. The height of the massage airbag is directly proportional to the airflow through its air ducts; a higher airflow results in a greater height and stronger massage, and vice versa. The arrangement of the air ducts is also very important. In seats with limited space, the air ducts are often placed between components or in narrow spaces. When a person sits on a deformed seat, the air ducts can become compressed or bent, trapping air and preventing the airbags from inflating, thus rendering the system ineffective.

[0004] The existing patent authorization announcement number: CN 221075591 U, discloses a novel air duct and pneumatic system, including an air duct body located inside a car seat. The outer wall of the air duct body has multiple rib-like structures distributed circumferentially around the air duct body. The air duct body and the rib-like structures are made of a soft material. In use, the air duct body is positioned between the air-using component and the air source inside the car seat, and the air source delivers gas to the air-using component through the air duct body. Compared to the prior art where the outer surface of the air duct body is smooth and the tube wall has no supporting structure, the air duct body in this application has rib-like structures distributed circumferentially on its outer wall. When the air duct body is bent to its limit inside the seat, the outer wall of the air duct body is supported by the rib-like structures. The rib-like structures are in contact with each other, and there are still gaps between the outer walls of the air duct body. This avoids the air duct body from becoming stuck or causing abnormal noise due to reduced gas flow caused by bending, thus enhancing the service life of the air duct and preventing it from affecting other functions of the entire seat system.

[0005] In existing technologies, although multiple rib-like structures are provided on the outer wall of the trachea body and these rib-like structures are distributed around the trachea body circumferentially, the trachea body can still be kinked when subjected to external force compression or bending, resulting in reduced or blocked airflow. At the same time, the current industry solutions use metal springs to support the trachea, but this is difficult to install and costly. Utility Model Content

[0006] Therefore, to solve the above-mentioned technical problems, this utility model proposes a tracheal anti-compression and air-trapping structure, including a tracheal body 10. The tracheal body 10 is a tubular structure with an internal airflow channel. The tracheal body 10 is made of a flexible material. A support component 20 is provided inside the tracheal body 10. The support component 20 includes at least one polyhedral rib 30. The surface of the polyhedral rib 30 is provided with a guide groove or guide hole to enhance airflow. The polyhedral rib 30 is made of plastic. When the tracheal body 10 is subjected to external compression or bending, the polyhedral rib 30 supports the inner wall of the tracheal body 10, thereby preventing the closure of the airflow channel. By providing the support component 20 inside the tracheal body 10, the support component 20 can effectively support the inner wall of the tracheal body 10 when subjected to external compression, thus ensuring airflow. At the same time, it is easy to install and reduces costs.
