Composite sliding hard pipe ventilation system applied to vehicle seat and vehicle

Abstract

The invention relates to a composite sliding hard pipe ventilation system and a vehicle, which can meet the requirements of low sitting posture of a driver, seat height adjustment and forward sliding long stroke, ensure the requirements of sealing, flow resistance, front-row footstep space and design space between rear-row footsteps and a seat framework and an automobile body, and enable the ventilation system to be installed on the whole automobile to meet the seat adjustment function, and achieve the product industrialization quality and guarantees that the long-stroke structure is hidden and not exposed. The system comprises: a seat air duct system comprising: a transverse fixed pipe arranged to move with a seat frame for introducing air-conditioning air to a cushion and a backrest; a connecting air pipe which is arranged between the seat cushion and the vehicle floor, is kept in a fixed state and is used for receiving the introduced air-conditioning air; a composite sliding mechanism which is arranged between the connecting air pipe and the transverse fixed pipe and used for transmitting the air-conditioning air blown out of the air outlet of the connecting air pipe to the transverse fixed pipe, and the composite sliding mechanism and the transverse fixed pipe are continuously located below the cushion in the moving process.

Description

technical field [0001] The invention belongs to an automobile seat ventilation system, and in particular relates to a composite sliding hard pipe ventilation system applied to a seat with an adjustable skeleton adjustment of a passenger car and an automobile. Background technique [0002] Such as figure 1 As shown, in the prior art, a single corrugated hose is used to introduce the air-conditioning air from the air conditioner to the cold and hot air to the lower part of the seat cushion, such as figure 1 As shown, the system provided by this solution includes a central control box 26, a traditional seat ventilation bellows 27, a traditional seat ventilation cushion air duct 28, and the traditional seat ventilation bellows 27 draws air from the central control box 26 into the traditional seat. In the ventilation duct 28 of the cushion. [0003] In addition, refer to figure 2 , the prior art also provides a retractable car seat ventilation pipeline, including an L-shaped ...

AI Technical Summary

Problems solved by technology

[0004] After careful analysis by the inventor, these solutions are not feasible in engineering. Although they can be simple and ventilated, they cannot have product engineering sealing performance and when the seat moves, the hose will be seriously bent, which will affect the CFD aerodynamics. Performance, the long-distance pipes are bent and stuck in the lower part of the seat, exposed to the outside of the seat, which is not aesthetically pleasing, and occupies a lot of space under the seat, affecting the passenger's footstep space. The most important thing is that this method cannot satisfy the seat requirements. Adapt to the layout requirements of low sitting posture (coupe or low sitting posture car)
