A composite sliding hard pipe ventilation system applied to a vehicle seat and an automobile

Abstract

This scheme relates to a composite sliding hard pipe ventilation system and a car, which can meet the driver's low sitting posture, high-profile seat and long front sliding travel, and ensure that it can meet the requirements of sealing, flow resistance, front footstep space and rear footsteps and seats. The design space between the skeleton and the car body makes it possible to install on the vehicle to satisfy the seat adjustment function, and to have the industrial quality of the product, ensuring that the long-stroke structure is concealed and not exposed. The system includes: a seat air duct system, including: a lateral fixing duct arranged to move with the seat frame for introducing air-conditioning air to the seat cushion and the backrest; a connecting air duct arranged to be in the seat cushion between the vehicle floor and the vehicle floor and in a fixed state for receiving the introduced air-conditioning air; a composite sliding mechanism, which is arranged between the connecting air duct and the lateral fixed The air-conditioning wind is transmitted to the lateral fixed pipe, and the composite sliding mechanism and the lateral fixed pipe are continuously positioned under the seat cushion during the movement.

Description

technical field [0001] The invention belongs to a vehicle seat ventilation system, and in particular relates to a composite sliding hard pipe ventilation system and an automobile which are applied to a passenger vehicle adjustable seat with an adjustable frame. Background technique [0002] like figure 1 As shown, in the prior art, a single corrugated hose is used to introduce cold and hot air from the air conditioner 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 leads the wind from the central control box 26 into the traditional seat. The ventilation cushion is in the air duct 28 . [0003] In addition, refer to figure 2 , the prior art also provides a retractable car seat ventilation pipeline, including an L-shaped pipe 10, a straight pip...

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)
