[0039] The present application will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the related invention and are not intended to limit the invention. Additionally, it should be noted that for the sake of convenience of description, only the parts related to the invention are shown in the drawings

[0040] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The following will describe the present application in detail with reference to the drawings and in conjunction with the embodiments.

[0041] Reference Figure 1 , in the existing ventilation seat, the spring frame 3 is arranged inside the seat, the airbag assembly 1 is arranged between the spring frame 3 and the seat foam 4 and fixed on the seat foam 4. An air outlet 2 is arranged on one side of the airbag assembly 1 close to the spring frame 3; the fan main body 5 is installed on the spring frame 3 through the cooperation of a fan fixing bracket 19 and a buckle 17. The fan main body 5 is connected to the air outlet 2, and then blows air or sucks air to the airbag assembly 1 to achieve the purpose of seat ventilation. Since the fan main body 5 is rigidly connected to the spring frame 3 through the fan fixing bracket 19, when the fan main body 5 works, the vibration is transmitted to the seat surface through the fan fixing bracket 19 and the spring frame 3, resulting in a poor riding experience for the occupant. To solve this problem, the present application aims to provide a soft connection installation structure for the seat fan to reduce the vibration transmission when the fan main body 5 works.

[0042] Specifically, the airbag assembly 1 includes an airbag, which mainly includes an upper sealing layer 1-1, a lower sealing layer 1-2 and an intermediate air distribution layer 1-3. The upper sealing layer 1-1 is a PU layer, the lower sealing layer 1-2 is a laminated non-woven fabric, and the upper sealing layer 1-1 is adhered to the bottom surface of the seat cushion through a double-sided tape 1-4, as Figure 20 shown; the air distribution layer 1-3 can be a three-dimensional knitted mesh or can be formed with a plurality of channels.

[0043] Embodiment 1

[0044] Please refer to Figure 2-9 , the present application provides a soft connection installation structure for a seat fan, which is used to connect to the air outlet 2 on the airbag assembly 1. A spring frame 3 is arranged on one side of the airbag assembly 1 close to the air outlet 2, and includes:

[0045] A fan main body 5, the fan main body 5 is arranged on the side of the spring frame 3 away from the airbag assembly 1, and the fan main body 5 is used to blow air or suck air from the air outlet 2 to the airbag assembly 1;

[0046] The fan connector 6 passes through the gap 20 on the spring frame 3. The fan connector 6 includes an air outlet connection part 7, a flexible connection structure 9, and a fan connection part 8. The flexible connection structure 9 is arranged between the air outlet connection part 7 and the fan connection part 8, and the flexible connection structure 9 is made of a soft elastic material; the air outlet connection part 7 is formed at one end of the flexible connection structure 9 and connects to the air outlet 2, the fan connection part 8 is formed at the other end of the flexible connection structure 9 and connects to the air flow port on the fan body 5. The flexible connection structure 9 is made of a soft material and can shrink under pressure; one of the air outlet connection part 7 and the fan connection part 8 is made of a soft material, and the other is made of a hard material.

[0047] Specifically, the soft connection installation structure of the seat fan provided in this application is installed inside the seat. The fan body 5 is arranged on the side of the spring frame 3 away from the air bag assembly 1. The soft connection structure 9 of the fan connector 6 is composed of the air outlet connection part 7 and the fan connection part 8 respectively arranged at both ends of the soft connection structure 9. The soft connection structure 9 passes through the gap 20 between the steel wires on the spring frame 3. The interior of the soft connection structure 9 is hollow and is respectively communicated with the air outlet connection part 7 and the fan connection part 8 at both ends. The air outlet connection part 7 is arranged on the side of the spring frame 3 close to the air bag assembly 1 and is communicated with the air outlet 2. The fan connection part 8 is connected to the air flow port of the fan body 5. The fan on the fan body 5 blows or sucks air to the air bag assembly 1 through the air flow port and then through the fan connector 6. On the one hand, the fan connector 6 can improve the airtightness between the fan body 5 and the air bag assembly 1; on the other hand, it connects and fixes the fan body 2 and the air bag assembly 1, without connecting the fan body 2 to the spring frame 3, avoiding the vibration generated during the operation of the fan body 5 from being transmitted to the seat surface and improving the comfort of the occupant.

[0048] Specifically, the soft elastic structure 9 can be selected as an elastic corrugated pipe, which can change the length of the elastic corrugated pipe when the human body is sitting or the installation space is limited, better compatible with the distance between the fan body 5 and the air bag assembly 1. At the same time, using the characteristics that the elastic corrugated pipe has elasticity and can freely expand and contract under pressure can reduce the transmission of vibration during the operation of the fan body 5. Optionally, the elastic corrugated pipe is provided with at least one corrugation, and the number of corrugations can also be adjusted according to the actual situation.

[0049] In addition, one of the air outlet connection part 7 and the fan connection part 8 is made of a soft material, and the other is made of a hard material. When the air outlet connection part 7 is made of a soft material, the vibration transmission between the fan connecting piece 6 and the air bag assembly 1 can be reduced to reduce the vibration on the seat surface. When the fan connection part 8 is made of a soft material, the vibration transmission between the fan connecting piece 6 and the fan main body 5 can be reduced to reduce the vibration on the seat surface. Cooperating with the vibration damping effect of the soft elastic structure 9 can further reduce the vibration transmission; setting one of the air outlet connection part 7 and the fan connection part 8 as a hard material can maintain good connection strength while having a good vibration damping effect. Optionally, the soft material in this embodiment is silicone, rubber or other soft materials.

[0050] Further, the fan main body 5 is detachably connected to the fan connection part 8.

[0051] Specifically, when the fan main body 5 and the fan connection part 8 are detachably connected, the fan connection part 8 can be made of a soft material or a hard material. The purpose of the detachable connection is to facilitate the installation and disassembly of the fan connecting piece 6 and the fan main body 5. When the fan connection part 8 is made of a soft material, the fan main body 5 and the fan connecting piece 6 are in a soft connection. When the fan connection part 8 is made of a hard material, the air bag assembly 1 and the fan connecting piece 6 are in a soft connection. In either case, the fan assembly 5 and the air bag assembly 1 are in a soft connection, which can reduce the vibration transmission while realizing the detachable of the fan main body 5.

[0052] Further, the fan connection part 8 includes a plurality of first hanging parts 10. The plurality of first hanging parts 10 are arranged at one end of the soft connection structure 9 away from the air bag assembly 1 and are arranged circumferentially along the end face of the soft connection structure 9. The first hanging part 10 can be hung with the fan main body 5; a plurality of second hanging parts 11 are arranged on the circumferential side of the fan main body 5. The second hanging part 11 protrudes radially outward along the fan main body 5 and can be hung with the first hanging part 10.

[0053] Specifically, in this embodiment, the fan main body 5 and the fan connecting piece 6 are hung with each other. The fan connection part 8 in this embodiment is composed of a plurality of first hanging parts 10, as Figure 5 shown, the plurality of first hanging parts 10 extend downward; a second hanging part 11 corresponding to the first hanging part 10 is arranged on the side wall of the fan main body 5. The second hanging part 11 is a protrusion extending radially along the fan main body 5 on the side wall of the fan main body 5; the detachable connection between the fan main body 5 and the fan connecting piece 6 is realized by hanging the first hanging part 10 with the second hanging part 11.

[0054] Further, an interface connection part 16 is provided on the spring frame 3, and the air outlet connection part 7 is connected to the interface connection part 16.

[0055] Specifically, to further improve the firmness of the installation of the fan connector 6, an interface connection part 16 is provided on the spring frame 3.

[0056] Mounting holes are correspondingly provided on the interface connection part 16 and the air outlet connection part 7, and the air outlet connection part 7 is further connected to the interface connection part 16 through a buckle 17, so as to

[0057] fix the fan connector 6 by establishing a connection between the air outlet connection part 7 and the spring frame 3. In this case, regardless of whether the fan connection part 8 is made of a soft material or a hard material, the fan main body 5 and the spring frame 3 are both connected through a soft elastic structure 9, so the fan main body 5 and the spring frame 3 are both soft-connected, so that vibration will not be transmitted to the spring frame 3 and transmitted to the seat surface through the spring frame 3.

[0058] Specifically, the air outlet connection part 7 and the interface connection part 16 can be connected through a buckle 17. Mounting holes are opened on both the air outlet connection part 7 and the interface connection part 16, and the fixing is achieved by clamping the buckle 17 with the mounting hole on the air outlet connection part 7 and the mounting opening on the interface connection part 16, as Figure 7 shown; or the buckle 17 and the air outlet connection part 7 are of an integral structure; or a rubber rivet is integrally formed on one side of the air outlet connector 7 close to the soft elastic structure 9, and the fixing is achieved by passing the rubber rivet through the mounting hole on the interface connection part 16.

[0059] Further, the fan connector 6 is pressed and fitted on the air bag assembly 1 at a position corresponding to the air outlet 2 through the spring frame 3, or is fixedly connected to the air outlet 2 on the air bag assembly 1.

[0060] Specifically, when the fan connector 6 is pressed and fitted with the air bag assembly 1 through the spring frame 3, there is no need to connect the air outlet connection part 7 and the air outlet 2 of the air bag assembly 1. The pressing action of the spring frame 3 makes the position between the air outlet connection part 7 and the air outlet 2 fit tightly, thereby improving the airtightness after connection; if the air outlet connection part 7 is fixedly connected to the position on the outer peripheral side of the corresponding air outlet 2 on the air bag assembly 1, when the air outlet connection part 7 is made of a hard material, optionally, the air outlet connection part 7 is connected to the air bag assembly 1 by ultrasonic welding, and when the air outlet connection part 7 is made of a soft material, optionally, the air outlet connection part 7 is connected to the air bag assembly 1 by sewing.

[0061] Furthermore, there is no limitation on the cross-sectional shapes of the air outlet connection part 7 and the flexible connection structure 9, which can be circular, rectangular, etc. The shapes of the air outlet connection part 7 and the flexible connection structure 9 can be set according to the gaps between the steel wires on the spring frame 3, so that the fan connector 6 has better compatibility and facilitates the installation of the fan main body 5.
