Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to a rear seat structure with blowing and massage functions. Background Technology

[0002] In the modern automotive industry, as consumers' demands for ride comfort continue to rise, the functional design of rear seats has gradually become an important direction in automotive seat research and development. Among them, rear seats with air conditioning and massage functions have received widespread attention in the market because they can effectively alleviate passenger fatigue during long journeys and enhance the riding experience.

[0003] However, traditional rear seats generally face structural design challenges when implementing airflow and massage functions. Specifically, the airflow and massage components of traditional rear seats (such as fans, air pumps, and massage airbags) require a significant amount of space to install (rear seats typically include four-quarter and six-quarter seats, especially the four-quarter seats, where space is limited, making it inconvenient to install fans and air pumps). This results in a less compact overall seat structure, increasing not only the seat's volume and thickness but also limiting the layout space for other internal components (such as wiring harnesses and sensors), causing numerous inconveniences in seat design and production. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model aims to provide a rear seat structure with a compact structure and reasonable layout, featuring air blowing and massage functions. This rear seat structure should be able to efficiently integrate air blowing and massage function components within a limited space, while ensuring tight connections and smooth airflow between the components, thereby improving the overall performance and riding comfort of the seat.

[0005] To achieve the above objectives, this utility model proposes a rear seat structure with blowing and massage functions, including a backrest frame, a fan, and an air pump. The backrest frame is a tubular frame structure, including a backrest frame and a backrest sheet metal. The backrest sheet metal is installed in the lower part of the backrest frame and has two hollowed-out sections. The fan and air pump are respectively installed in the two hollowed-out sections, both of which adopt a protruding design, with one end protruding from the front of the backrest sheet metal and the other end protruding from the back of the backrest sheet metal. The air pump is equipped with an air pump control valve, which is a flat box-shaped structure and is installed on the back of the backrest sheet metal. The front side of the backrest sheet metal has an air bag, and the front side of the air bag has several massage air bags. The fan is connected to the air bag. The massage air bags are embedded in the backrest foam and are respectively connected to the air pump control valve through branch air pipes. The air pump control valve is connected to the air pump through a main air pipe. Several ventilation holes are provided on the front of the air bag and on the backrest foam.

[0006] In the above solution: the bottom and both sides of the backrest sheet metal are provided with lugs, and each lug is fixed to the backrest frame with screws. The structure is simple and the assembly is convenient.

[0007] In the above solution, the massage air bags are arranged in a matrix, which ensures that all parts of the passenger's back can be evenly stimulated by the massage, avoiding insufficient or excessive massage in certain areas, and providing passengers with a more comprehensive and comfortable massage experience.

[0008] In the above solution, the massage air bags are divided into two rows, with three in each row. This partitioned design allows for more targeted massage stimulation of different areas of the back, without being too dense or too loose.

[0009] In the above solution: Both ends of the backrest sheet metal are provided with through holes. The air pipes connecting the three massage airbags on the left side pass through the through holes on the left side and are connected to the air pump control valve. Similarly, the air pipes connecting the three massage airbags on the right side pass through the through holes on the right side and are connected to the air pump control valve. The air pipes are arranged along a specific path, neatly and orderly, greatly improving the cleanliness of the seat's interior. This not only makes the internal structure of the seat clearer, facilitating subsequent maintenance and repair, but also reduces the potential risk of malfunctions caused by disorganized air pipes, such as pipe wear and deformation due to compression.

[0010] In the above solution: two lugs are spaced apart at the bottom of the backrest sheet metal, and one lug is located in the middle of each side of the backrest sheet metal; the two bottom lugs are staggered front to back, with one lug close to the front of the backrest frame and the other close to the back of the backrest frame; the side lugs are also staggered front to back, with one lug close to the front of the backrest frame and the other close to the back of the backrest frame. This three-dimensional lug distribution method forms a three-dimensional force system through alternating front and back support, which not only ensures structural stability but also optimizes space utilization.

[0011] The beneficial effects of this utility model are:

[0012] 1. Traditional rear seat ventilation and massage functions require significant space and are inconvenient to install. This new rear seat structure integrates the fan and air pump into two hollow sections, achieving efficient integration of the ventilation and massage components. This design fully utilizes the internal space of the backrest frame, avoiding the problem of independent functional components and large space occupation in traditional seats, resulting in a more compact overall structure and significantly improved space utilization. 2. Massage airbags are embedded in the backrest foam and connected to the air pump control valve via branch pipes. The air pump control valve precisely controls the inflation and deflation process, allowing the massage airbags to inflate and deflate according to a preset rhythm and intensity, thus providing effective massage to the passenger's back. 3. Because this invention integrates the ventilation and massage components onto the backrest sheet metal, and the components are modularly designed, they are easy to disassemble and replace. This design not only reduces seat maintenance costs but also improves seat reliability and lifespan. Furthermore, the compact structure reduces seat thickness and cost, making this invention more competitive in the market. Attached Figure Description

[0013] The above and / or additional aspects and advantages of this utility model will become apparent and readily understood from the description of the embodiments taken in conjunction with the following drawings, in which:

[0014] Figure 1 This is a rear view of the present invention.

[0015] Figure 2 This is a structural diagram of the sheet metal backrest.

[0016] Figure 3 This is a front view of the present invention. Detailed Implementation

[0017] like Figure 1 As shown in Figure 3, a rear seat structure with blowing and massage functions mainly consists of a backrest frame, a fan 1, and an air pump 2. The backrest frame is a tubular frame structure, which includes a backrest frame 3.

[0018] The backrest frame also includes a backrest sheet metal 4, which is installed in the lower part of the backrest frame 3 (equivalent to the backrest frame 3 surrounding the backrest sheet metal 4). The backrest sheet metal 4 has two hollow parts 41, and the fan 1 and the air pump 2 are respectively installed in the two hollow parts 41 (installed with the help of auxiliary brackets). Both adopt a protruding design, with one end protruding from the front of the backrest sheet metal 4 and the other end protruding from the back of the backrest sheet metal 4.

[0019] Air pump 2 is equipped with air pump control valve 5, which is a flat box-shaped structure and is installed on the back of backrest sheet metal 4. Air bag 6 is located on the front side of backrest sheet metal 4, and several massage air bags 7 are located on the front side of air bag 6. Fan 1 is connected to air bag 6. Massage air bags 7 are embedded in the backrest foam and are connected to air pump control valve 5 via branch air pipes 8. Air pump control valve 5 is connected to air pump 2 via main air pipe. Several ventilation holes are provided on the front of air bag 6 and on the backrest foam.

[0020] Ideally, the bottom and both sides of the backrest sheet metal 4 are provided with lugs 42, and each lug 42 is fixed to the backrest frame 3 by screws. The structure is simple and the assembly is convenient.

[0021] Ideally, the massage airbags 7 are arranged in a matrix. This matrix arrangement ensures that all parts of the passenger's back are evenly stimulated by the massage, avoiding insufficient or excessive massage in certain areas, and providing passengers with a more comprehensive and comfortable massage experience.

[0022] Ideally, the massage airbags should be divided into two rows of three on each side. This zoned design allows for more targeted massage stimulation of different areas of the back, without being too dense or too loose.

[0023] Ideally, the backrest sheet metal 4 should have through holes on both the left and right ends. The air pipes 8 connected to the three massage air bags 7 on the left should pass through the through holes on the left and connect to the air pump control valve 5. Similarly, the air pipes 8 connected to the three massage air bags 7 on the right should pass through the through holes on the right and connect to the air pump control valve 5. The air pipes 8 are arranged along a specific path, neatly and orderly, greatly improving the cleanliness of the seat interior. This not only makes the internal structure of the seat clearer, facilitating subsequent maintenance and repair, but also reduces the potential risk of malfunctions caused by disorganized air pipes 8, such as air pipe wear and deformation due to compression.

[0024] Ideally, the bottom of the backrest sheet metal 4 is provided with two lugs 42 spaced apart, and one lug 42 is provided on each of the middle parts of both sides of the backrest sheet metal 4; the two lugs 42 at the bottom are staggered front to back, with one lug 42 close to the front of the backrest frame 3 and the other lug 42 close to the back of the backrest frame 3; the lugs 42 on both sides are also staggered front to back, with one lug 42 close to the front of the backrest frame 3 and the other lug 42 close to the back of the backrest frame 3. This three-dimensional distribution of lugs 42 forms a three-dimensional force system through alternating support from the front and back, which not only ensures structural stability but also optimizes space utilization.
