Description

TECHNICAL FIELD

[0001] The present application relates to the field of automobile parts, in particular to a seat framework with air supply function. BACKGROUND

[0002] With the continuous development of the automobile industry, consumers' requirements for the comfort of car seats are gradually increasing, and the ventilation function of the seat has become one of the important configurations for improving comfort in modern cars. In the prior art, the seat framework is usually designed with flow channels, air bags or air plates and other components, and the circulation of air is achieved through fans or air guiding systems, thereby providing ventilation and cooling effects for the car owner. This structure has been relatively mature in technical implementation and can meet the daily use requirements, providing users with a better comfortable experience. However, with the intensification of market competition and the improvement of consumers' sensitivity to car prices, the control of seat production and assembly costs has become a new industry challenge.

[0003] Although the existing seat ventilation system can complete its basic functions, its structure is relatively complex, involving the assembly and coordination of multiple components. For example, the combination of flow channels, air bags, air plates and other components not only increases the production steps of the seat, but also makes the assembly process of the seat cumbersome, resulting in a longer production cycle and higher assembly cost. In addition, the design of these components usually requires high-precision manufacturing and assembly processes, increasing the requirements for production equipment and manual operation, thereby further increasing the cost. While automobile manufacturers are under cost pressure, these complex ventilation structures make the overall structure of the seat framework more massive, increasing the weight of the seat and making it difficult to achieve lightweight design.

[0004] Therefore, while the existing technology realizes the ventilation function of the seat, it also exposes some deficiencies. First, the complexity of the structure directly leads to the increase of production and assembly costs, and second, redundant components and complex assembly steps affect production efficiency and increase the operating costs of enterprises.

[0005] Under this background, it is particularly important to develop a new seat framework with air supply function. CONTENT OF THE INVENTION

[0006] The purpose of the present application is to at least overcome the deficiencies of the prior art, provide a seat framework with air supply function, which simplifies the existing seat structure and optimizes the implementation of the ventilation function, so as to reduce production and assembly costs and improve production efficiency while ensuring comfort. In addition, the new technology can also reduce redundant components and simplify assembly processes.

[0007] To achieve the above object, the application discloses a seat skeleton with air supply function, which comprises a seat frame, a seat cushion frame mounted on the seat frame, a backrest frame hingedly connected with the seat frame through a rotating shaft,

[0008] Among them, as a necessary component to realize the air supply function, the seat cushion frame and the backrest frame are respectively provided with a support seat frame and a support back frame with air inlet;

[0009] Among the above, the support seat frame is connected with the seat cushion frame, which supports the seat cushion of the seat and improves the structural strength of the seat skeleton; among the above, the support back frame is connected with the backrest frame, which supports the backrest of the seat and improves the structural strength of the seat skeleton; in structure, the support seat frame and the support back frame have the same structure and are both in branch structure;

[0010] Specifically, the support back frame comprises a hollow main back pipe vertically arranged and a hollow support back pipe extending upwardly from the main back pipe, the support back pipe and the main back pipe form a back air flow channel in communication with each other, in addition, a plurality of air outlet holes are formed on the support back pipe and the main back pipe and face the backrest direction of the seat;

[0011] The support seat frame comprises a main cushion pipe horizontally and downwardly inclined, and a support cushion pipe extending upwardly from the main cushion pipe, the support cushion pipe and the main cushion pipe form a seat air flow channel in communication with each other, and like the support back frame, a plurality of air outlet holes are formed on the main cushion pipe and the support cushion pipe and face the sitting direction of the seat.

[0012] In some embodiments, the main back pipe, the support back pipe, the main cushion pipe and the support cushion pipe are hollow composite pipes; comprising a metal layer and an inner lining layer located in the metal layer. Preferably, the inner lining layer is a Teflon layer, which has good hydrophobicity and stain resistance.

[0025] Referring to the drawings Figure 1 and2 The seat frame system with air supply function of the present disclosure aims to improve seat comfort, simplify seat frame structure, reduce assembly difficulty, and improve integration.

[0026] In terms of specific structure, the main components of this seat frame system include bed chair frame 1, seat cushion frame 2, backrest frame 3, support seat frame 4, support back frame 5, main back tube 6, support back tube 7, main cushion tube 8, and support cushion tube 9. These components, through precise design and reasonable cooperation, not only ensure the structural strength and stability of the seat, but also realize a highly integrated ventilation system. The following describes each component in detail and its connection and cooperation, showing how these components work together to provide excellent seat ventilation.

[0027] Bed chair frame 1 is the basic support structure of the entire seat frame, and support seat frame 4 is connected to bed chair frame 1 through a fixing device. Seat cushion frame 2 is connected to bed chair frame 1 through a fixing component, ensuring stable support in the seat cushion area. Backrest frame 3 is hinged to bed chair frame 1 through a rotating shaft, supporting the adjustment of the back of the seat, and can adjust the chair back angle according to the needs of the occupant, improving the comfort of the seat.

[0028] In order to realize the ventilation function of the seat, support seat frame 4 and support back frame 5 are respectively arranged inside seat cushion frame 2 and backrest frame 3, respectively providing support for the seat cushion and backrest parts. These support frames adopt a hollow structure, which can not only provide the required support strength, but also form an air flow passage. Support seat frame 4 and support back frame 5 adopt a dendritic structure design, which minimizes the amount of material used while maintaining the necessary strength.

[0029] Specifically, support back frame 5 includes a vertical main back tube 6, which is a hollow tube with multiple ventilation holes. Main back tube 6 is connected to the air blower or air conditioning system inside the seat, and cold air or adjusted air is introduced into the back of the seat through the pipeline. Support back tube 7 extends obliquely upward from main back tube 6, and support back tube 7 is connected to main back tube 6 through a back ventilation flow channel, forming a continuous air flow passage to ensure that air flows uniformly to the back area of the seat. The design shape of support back tube 7 and the position of the air outlet holes can accurately control the direction and intensity of the air flow, avoiding excessive concentration of air at a certain point and improving the uniformity of ventilation.

[0030] In the backrest area, the air outlet holes of support back tube 7 are designed to face the direction of the backrest, ensuring that cold air or fresh air can effectively flow into the backrest area, providing comfortable temperature control effect for the occupant. The number and aperture of these air outlet holes are accurately calculated to ensure the efficiency and comfort of air flow, avoiding excessive air flow or local overheating.

[0031] The design of the support seat frame 4 is similar to the support back frame 5, and the ventilation system of the seat cushion part is realized through the main cushion pipe 8 and the branch cushion pipe 9. The main cushion pipe 8 is a downwardly inclined hollow pipe, designed to be inclined downward horizontally to ensure smooth air flow. The branch cushion pipe 9 extends upwardly from the end of the main cushion pipe 8 and is connected with the main cushion pipe 8 through the seat ventilation flow channel to form the ventilation channel of the seat cushion part. Similar to the branch back pipe 7, the branch cushion pipe 9 is also provided with a plurality of air outlets, which are directed towards the seat cushion area to ensure that the seat cushion area can obtain uniform and comfortable air flow.

[0032] In order to prevent water accumulation or contaminants from blocking the ventilation flow channel, the pipes of the main back pipe 6, the branch back pipe 7, the main cushion pipe 8 and the branch cushion pipe 9 are all made of composite material, with a metal outer layer and a Teflon inner lining. The metal layer provides the required strength and durability of the pipe, which can withstand the pressure and stress in long-term use, ensuring the long-term stability of the seat frame. The Teflon lining has good hydrophobicity, which can effectively prevent water from accumulating in the pipe and reduce the retention and pollution of water vapor. In addition, the anti-pollution property of Teflon can ensure that the ventilation system is not easily blocked by impurities during use, ensuring the durability of the ventilation effect.

[0033] In order to ensure the ventilation effect of the seat and the precise control of air flow, the main back pipe 6 and the main cushion pipe 8 are both equipped with regulating valves. The valves can adjust the air flow as needed to ensure the comfort of the seat under different environmental conditions. In the car air conditioning system, the main back pipe 6 is connected with the air duct of the air conditioning system through the pipe, and the air volume of the air conditioning system controls the air flow into the seat through the valve. When the seat ventilation function is started by the owner, the air conditioning system will introduce cold air through the main back pipe 6, and the air will be transmitted to the back and seat cushion area of the seat through the back ventilation flow channel and the seat ventilation flow channel.

[0034] In specific implementation, the fan in the seat can be automatically adjusted according to the needs of the owner. When the temperature in the car is high or the owner needs to enhance the ventilation effect of the seat, the fan will start and send more air into the seat through the main back pipe 6 and the main cushion pipe 8, thereby enhancing the air circulation of the back and seat cushion area. The start of the fan is automatically realized through the seat control system, and the running state of the fan can be adjusted through the control panel in the car or the seat setting button.

[0035] In addition, the ventilation flow channel of the seat is designed with a downwardly inclined layout, which effectively avoids the retention of condensed water or particulate matter in the ventilation pipe, ensuring the efficient ventilation of the seat in long-term use. Especially in humid environments, the downwardly inclined ventilation flow channel can timely drain the accumulated water, keep the seat dry, and prevent bacteria from breeding and odor from being generated.

[0036] The structural design of the seat frame, combined with the precise control of the ventilation system and the regulating valve, not only provides efficient air circulation, but also ensures long-term comfort and stability of air flow. In actual use scenarios, whether in hot summer or humid environment, the seat ventilation system can effectively regulate temperature and humidity, improve the riding comfort of the driver and passengers, and avoid discomfort or fatigue caused by long-time driving.

[0037] In summary, the seat frame system with air supply function provides efficient ventilation function for the driver through fine structural design and optimized air circulation path, and performs well in ensuring the comfort and functionality of the seat. At the same time, the use of high-quality composite materials and inner lining layer prolongs the service life of the seat frame system and improves the durability and stability of the system.

[0038] Although exemplary embodiments of the present disclosure have been described, those skilled in the art will understand that various changes and modifications can be made to the exemplary embodiments of the present disclosure without departing from the spirit and scope of the present disclosure in essence. Therefore, all changes and modifications are included in the protection scope of the present disclosure defined by the claims. The present disclosure is defined by the appended claims, and equivalents of these claims are also included.
