Description

Air pipe extrusion-proof air trapping structure Technical Field The utility model belongs to the technical field of automobile parts, and particularly relates to an air pipe extrusion-proof air trapping structure. Background Along with the development of technology and the improvement of the requirements of people on travelling comfort, the massage of the seat waist support becomes an important factor of many consumers for purchasing new vehicles. Along with the rapid promotion of the intelligent process of the automobile, the waist support massage gradually becomes an automobile standard product. For the lumbar support massage system, the comfort of the massage strength is important. The jacking height of the massage air bag is in direct proportion to the air flow of the air pipe, the air flow is large, the jacking height is high, the massage strength is strong, and conversely, the massage strength is weak. The air pipe is very important to arrange, the space in the seat is smaller, the air pipe is often arranged between parts or at a narrow boundary position, when a person takes the seat to deform, the air pipe is often pressed or bent to trap air, the air bag cannot be inflated, and the function is invalid. The prior patent grant bulletin number CN 221075591U discloses a novel air pipe and a pneumatic system, which comprises an air pipe body arranged in an automobile seat, wherein a plurality of rib structures are arranged on the outer wall of the air pipe body, the rib structures are circumferentially distributed around the air pipe body, the air pipe body and the rib structures are made of soft materials, when the novel air pipe is used, the air pipe body is arranged between an air utilization component and an air source in the automobile seat, the air source conveys air to the air utilization component through the air pipe body, compared with the prior art that the outer surface of the air pipe body is smooth and the pipe wall is not provided with a supporting structure, the rib structures are circumferentially distributed on the outer wall of the air pipe body, when the air pipe body is bent to a limit position in the seat, the rib structures are supported by the outer wall of the air pipe body, gaps are reserved between the rib structures, abnormal phenomena such as abnormal noise and the like after the air flow is reduced due to bending of the air pipe body are avoided, the service life of the air pipe is prolonged, and other using functions of the whole seat system are avoided. In the prior art, although a plurality of rib structures are arranged on the outer wall of the air pipe body and circumferentially distributed around the air pipe body, when the air pipe body is extruded or bent by external force, the air pipe body is still folded to cause the reduction of air flow or no circulation, and meanwhile, the current scheme in the industry uses a metal spring for supporting in the air pipe, but the installation is difficult and the cost is high.
