[0054] Please refer to Figures 1 - 12 together, and now the seat air suction system provided by the embodiment of the present application will be described.

[0055] This embodiment provides a seat air suction system, including a seat foam 1, a fan assembly 2, and an outer sealing layer 3.

[0056] The seat foam 1 refers to a foam-like structure formed by processing materials such as polyurethane through a specific technological process. The main function of the seat foam 1 is to improve the comfort and support of the seat. In this embodiment, an air duct groove 11, ventilation holes 12, and an installation groove 13 are provided on the seat foam 1. The installation groove 13 communicates with the air duct groove 11. Among them, the installation groove 13 is used to place the fan assembly 2, and the air duct groove 11 and ventilation holes 12 opened on the seat foam 1 are used to form an air duct structure.

[0057] Please refer to Figure 1 and Figure 2 , Figure 1 which is a schematic structural diagram of the seat air suction system, Figure 2 and Figure 2 is an exploded schematic diagram of the seat air suction system.

[0058] In , the seat foam 1 is shown, and the air duct groove 11, ventilation holes 12, and installation groove 13 opened on the seat foam 1 are also shown.

[0059] The seat foam 1 includes a first side and a second side arranged opposite to each other. Among them, the side that the user leans on is defined as the first side, that is, the front side, and the second side of the seat foam 1 is the rear side. The air duct groove 11 and the installation groove 13 are formed on the second side of the seat foam 1.

[0060] The ventilation holes 12 are provided on the air duct groove 11. That is, the air duct groove 11 includes a groove bottom surface and a groove side surface, and the ventilation holes 12 are provided on the groove bottom surface of the air duct groove 11. That is, the ventilation holes 12 connect the groove bottom surface of the air duct groove 11 and the first side of the seat foam 1.

[0061] Regarding the shape of the ventilation holes 12, the cross-sectional shape of the ventilation holes 12 can be circular, elliptical, square, etc. That is, the specific shape of the ventilation holes 12 is not limited.

[0062] Regarding the number of the ventilation holes 12, the number of the ventilation holes 12 is multiple, and the multiple ventilation holes 12 are spaced apart on the air duct groove 11. The number of the ventilation holes 12 can be reasonably set according to the size of the ventilation holes 12.

[0063] The fan assembly 2 is arranged in the installation groove 13. Please refer to Figure 3, which shows the fan assembly 2 disposed on the seat foam 1. An air suction port 211 and an air outlet 212 are formed on the fan assembly 2. When the fan assembly 2 is powered on and operates, air flow enters through the air suction port 211 and is discharged through the air outlet 212. Since the seat air suction system provided in this embodiment, the air suction port 211 of the fan assembly 2 is communicated with the air duct groove 11. That is, when the fan assembly 2 is powered on and operates, air flow enters the air duct groove 11 through the ventilation holes 12, flows along the air duct groove 11 to the air suction port 211 of the fan assembly 2, and then is discharged through the air outlet 212 of the fan assembly 2, realizing the air circulation in the human back and hip areas and achieving the cooling function. Please refer to Figure 5 , which shows the flow direction of the air flow in the air duct groove 11.

[0064] A connecting wire is provided on the fan assembly 2. The connecting wire passes through the seat foam 1 and is electrically connected to the control device of the vehicle. The control device controls the power on or off of the fan assembly 2, and thus controls the working state of the fan assembly 2.

[0065] Regarding the connecting wire of the fan assembly 2 passing through the seat foam 1, the air duct groove 11 and the ventilation holes 12 formed on the seat foam 1 can be reasonably utilized, so that the connecting wire of the fan assembly 2 passes through the seat foam 1 and is electrically connected to the control device of the vehicle.

[0066] As described above, the air duct groove 11 and the installation groove 13 are formed on the second side of the seat foam 1. An outer sealing layer 3 is also provided on the second side of the seat foam 1. The outer sealing layer 3 covers the air duct groove 11 and the fan assembly 2. An opening 321 is provided on the outer sealing layer 3. The opening 321 is communicated with the air outlet 212. Please refer to Figure 1 and Figure 2 , Figure 1 and Figure 2 which shows the outer sealing layer 3.

[0067] The outer sealing layer 3 not only plays a role in aesthetics. At the same time, the air duct groove 11 on the seat foam 1 and the outer sealing layer 3 cooperate to form an air duct, avoiding the need to provide an air bag on the seat foam 1 in the prior related art, so as to simplify the structure of the seat air suction system and reduce the number of components.

[0068] Please refer to Figure 1 , an opening 321 matching the air outlet 212 of the fan assembly 2 is provided on the outer sealing layer 3. When the fan assembly 2 is powered on and operates, the air flow discharged through the air outlet 212 of the fan assembly 2 can be discharged from the seat foam 1 through the opening 321 on the outer sealing layer 3.

[0069] Preferably, the outer sealing layer 3 is sealingly fitted with the seat foam 1 to prevent air leakage during the air suction process of the seat air suction system and reduce the ventilation efficiency. Exemplarily, the outer sealing layer 3 is adhered to the seat foam 1.

[0070] Exemplarily, the material of the outer sealing layer 3 is metal or plastic.

[0071] The seat suction system provided in this embodiment has a simple structure. The fan assembly 2 is directly installed in the seat foam 1, and structures such as the air bag are eliminated. This facilitates assembly and reduces costs. It can also further save the layout space of the entire chair, making it easier to configure a thin seat with a ventilation function.

[0072] Regarding the air intake 211 and the air outlet 212 on the fan assembly 2, in one embodiment, the fan assembly 2 includes a fan body 21 and a support structure 22. The support structure 22 is arranged on the side of the fan body 21 away from the outer sealing layer 3. The side of the fan body 21 facing the support structure 22 is the air intake 211. The support structure 22 is used to support the fan body 21 to connect the air intake 211 with the air duct groove 11.

[0073] The air intake 211 of the fan body 21 faces the bottom surface of the mounting groove 13. If the supporting structure 22 is not provided and the fan body 21 is directly attached to the bottom surface of the mounting groove 13, when the fan body 21 is working in a passband, it is difficult for the air flow to enter through the air intake 211. Therefore, it is necessary to design a supporting structure 22 to support the fan body 21 so that the air intake 211 of the fan body 21 is connected to the air duct groove 11 to ensure the normal operation of the fan body 21.

[0074] Regarding the support structure 22, there are three preferred embodiments as follows:

[0075] Embodiment 1:

[0076] The support structure 22 is a protective cover with mesh, and the support structure 22 is fixedly connected to the fan body 21. Figure 6 and Figure 7 , showing the support structure 22. Figure 6 is a schematic diagram of the structure of the fan assembly 2, Figure 7 It is an exploded schematic diagram of the support structure 22 and the fan body 21 in the fan assembly 2.

[0077] See also Figure 6 and Figure 7 The shape of the support structure 22 matches the shape of the fan body 21, and the overall outer contour is circular, and the support structure 22 covers the air inlet 211 of the fan body 21. When the fan body 21 is powered on, the airflow can enter the air inlet 211 of the fan body 21 through the mesh on the support structure 22.

[0078] Preferably, the support structure 22 is made of metal or plastic.

[0079] Preferably, see Figure 7, in the central region of the entire support structure 22, the distance from the fan main body 21 is greater than that from the outer edge region of the support structure 22. The central region of the support structure 22 is in contact with the bottom surface of the installation groove 13. While achieving a compact installation of the fan assembly 2 and the seat foam 1, it is beneficial for air flow to enter the air suction port 211 of the fan main body 21 through the support structure 22.

[0080] Regarding the specific structure of the support structure 22, by way of example, refer to Figure 6 and Figure 7 , the support structure 22 includes a first annular portion, a second annular portion, and a third annular portion that are concentrically arranged. Figure 6 and Figure 7 show three annular portions. Of course, the number of annular portions on the support structure 22 is not limited to three, and a reasonable number of annular portions can be set according to the actual situation. In Figure 6 and Figure 7 , the first annular portion and the second annular portion are connected by ribs, and the ribs are circumferentially spaced between the first annular portion and the second annular portion. The second annular portion and the third annular portion are connected by ribs, and the ribs are circumferentially spaced between the second annular portion and the third annular portion. The first annular portion is connected to the fan main body 21, and there is a spacing between the second annular portion and the third annular portion and the fan main body 21.

[0081] The support structure 22 is fixed on the fan main body 21. The support structure 22 can be detachably fixed on the fan main body 21 through a connecting member; or, the support structure 22 can be welded to the fan main body 21; or, the fan housing 214 of the fan main body 21 includes an upper housing and a lower housing, the upper housing and the lower housing are connected and their interiors enclose a fan blade accommodation cavity, and it can be arranged that the support structure 22 and the lower housing of the fan main body 21 are integrally cast.

[0082] Please refer to Figure 7 , usually a protective net 213 is provided at the air suction port 211 of the fan main body 21. When the support structure 22 is fixed on the fan main body 21, the protective net 213 can be removed.

[0083] The support structure 22 provided in this embodiment, while meeting the normal operation of the fan main body 21, has a simple structure and is convenient for production and implementation.

[0084] Embodiment Two:

[0085] The support structure 22 is made of a mesh material. The support structure 22 and the fan main body 21 are independent of each other and in contact, that is, the support structure 22 is not connected to the fan main body 21. The support structure 22 is limited and fixed in the installation groove 13 by one end of the fan main body 21 close to the support structure 22 and the bottom surface of the installation groove 13. Please refer to Figure 8, which shows an exploded view of the support structure 22 and the fan body 21 in the fan assembly 2.

[0086] The material of the support structure 22 is preferably a new type of pure fabric material, that is, 3DMesh material.

[0087] Regarding the shape of the support structure 22, it is preferably as follows. Refer to Figure 8 , the support structure 22 is integrally in a disc shape and matches the shape of the fan body 21.

[0088] In one example, the support structure 22 is not connected to the mounting groove 13; in another example, the support structure 22 is connected to the mounting groove 13. For example, the support structure 22 is pasted on the mounting groove 13. It is preferred that the support structure 22 is not connected to the mounting groove 13. Since the 3DMesh material has the advantage of good elasticity, the support structure 22 can be set not to be connected to both the fan body 21 and the mounting groove 13, but to be fixed between the fan body 21 and the mounting groove 13 by the elastic deformation of the support structure 22, thereby realizing the fixation of the support structure 22.

[0089] In this embodiment, by setting the support structure 22 made of a mesh material, while meeting the normal operation of the fan body 21, the structure is simple and the cost is low.

[0090] Embodiment Three:

[0091] Please refer to Figure 9 , the support structure 22 includes a protective cover 221 and a support member 222. The protective cover 221 is fixedly connected to the fan body 21, and the support member 222 is arranged on the side of the protective cover 221 facing away from the fan body 21. Please refer to Figure 9 , which shows the protective cover 221 and the support member 222.

[0092] The protective cover 221 in Embodiment Three is the support structure 22 (the protective cover with mesh holes) in Embodiment One; the support member 222 in Embodiment Three is the support structure 22 made of the mesh material in Embodiment Two.

[0093] In this embodiment, by simultaneously setting the protective cover 221 and the support member 222, it is beneficial for the air flow in the air duct groove 11 to enter the air inlet 211 more smoothly.

[0094] In this embodiment, the protective cover 221 is fixed on the fan body 21. The protective cover 221 can be detachably fixed on the fan body 21 through a connecting member; or, the fan body 21 can be welded on the fan body 21; or, it can be set that the fan body 21 and the lower shell of the fan body 21 are integrally formed by casting.

[0095] Please refer to Figure 9, generally, a protective net 213 is provided at the air inlet 211 of the fan body 21. When the protective cover 221 is fixed to the fan body 21, the protective net 213 can be removed.

[0096] The support member 222 is made of a mesh material. The material of the support member 222 is preferably a new type of pure fabric material, that is, 3DMesh material. The support member 222 is not connected to the protective cover 221. In one example, the support structure 22 is not connected to the mounting groove 13; in another example, the support structure 22 is connected to the mounting groove 13. For example, the support structure 22 is pasted on the mounting groove 13. Preferably, the support structure 22 is not connected to the mounting groove 13. Since the 3DMesh material has the advantage of good elasticity, the support structure 22 can be arranged not to be connected to the fan body 21 and the mounting groove 13, but to be fixed between the fan body 21 and the mounting groove 13 by the elastic deformation of the support structure 22.

[0097] In the first embodiment above, the support structure 22 is a protective cover with mesh holes, and the support structure 22 is fixedly connected to the fan body 21. It is also possible to arrange that the support structure 22 is not fixedly connected to the fan body 21, but to fix the support structure 22 on the mounting groove 13. For example, the support structure 22 can be pasted on the mounting groove 13 or the support structure 22 can be fixed on the mounting groove 13 by using a connecting member. Of course, when the support structure 22 is a protective cover with mesh holes, it is preferred to fixedly connect the support structure 22 to the fan body 21 in the manner of the first embodiment.

[0098] In the second embodiment above, the support structure 22 is made of a mesh material, and the support structure 22 is not connected to the fan body 21. It is also possible to arrange that the support structure 22 is connected to the fan body 21. For example, the support structure 22 can be pasted on the fan body 21. Of course, it is preferred to adopt the method of the second embodiment above, that is, to arrange that the support structure 22 is not connected to the fan body 21.

[0099] Similarly, for the third embodiment above, it is also possible to arrange that the support structure 22 is connected to the fan body 21. For example, the support structure 22 can be pasted on the fan body 21.

[0100] Based on the shape of the outer contour of the fan assembly 2, in one embodiment, please refer to Figure 2 , the mounting groove 13 includes a main body groove 131 and an outlet groove 132. The main body groove 131 is communicated with the outlet groove 132. The fan assembly 2 is embedded in the main body groove 131 and the outlet end of the fan assembly 2 is located in the outlet groove 132. The opening 321 on the outer sealing layer 3 is communicated with the outlet groove 132.

[0101] Please refer to Figure 2 , which shows the main body groove 131 and the outlet groove 132. Please refer to Figure 3, which schematically shows that the fan assembly 2 is embedded in the main body groove 131 and the outlet end of the fan assembly 2 is located at the outlet groove 132 .

[0102] In this embodiment, the installation groove 13 includes a main groove 131 and an outlet groove 132 to match the shape of the outer contour of the fan assembly 2 , so as to facilitate the assembly of the fan assembly 2 into the installation groove 13 .

[0103] In this embodiment, the side surface of the main body groove 131 is interference fit with the circumferential side surface of the fan assembly 2. Figure 4 , Figure 4 The side surface 1311 of the main groove is shown in the figure. The fan assembly 2 is embedded in the mounting groove 13. The fan assembly 2 does not need any additional components to be fixed in the seat foam 1, but is fixed in the seat foam 1 by a tight fit with the groove wall of the mounting groove 13, simplifying the structure of the seat suction system.

The shape of the opening 321 on the outer sealing layer 3 matches the shape enclosed by the first edge 1321, the second edge 1322, and the third edge 1323.

[0110] The opening 321 and the outlet groove 132 provided on the outer sealing layer 3 in this embodiment are conducive to cooperating with the air outlet 212 of the fan assembly 2, and when the fan assembly 2 is powered on and working, the airflow discharged from the air outlet 212 of the fan assembly 2 is led out.

[0111] In one embodiment, the seat air suction system further includes an inner sealing layer 4. The inner sealing layer 4 is attached to the seat foam 1. The area on the seat foam 1 where the inner sealing layer 4 is attached is the fitting area. The shape of the inner sealing layer 4 matches the shape of the fitting area. Grooves 41, through holes 42, and outlet grooves 43 are formed on the inner sealing layer 4. The grooves 41 and the through holes 42 cooperate with the air duct groove 11 and the ventilation holes 12 respectively.

[0112] Please refer to Figure 2 , which shows the inner sealing layer 4. By providing the inner sealing layer 4 attached to the seat foam 1, the strength of the seat can be improved. Please refer to Figure 2 , the shape of the inner sealing layer 4 matches the shape of the corresponding area on the seat foam 1. Please refer to Figure 12 , Figure 12 is Figure 10 the schematic cross-sectional view taken along the line B - B in Figure 12 , it can be seen that the groove 41 of the inner sealing layer 4 matches the air duct groove 11 on the seat foam 1, and the inner sealing layer 4 is attached to the seat foam 1.

[0113] By forming a groove 41 on the inner sealing layer 4 that cooperates with the air duct groove 11, that is, by clamping the groove 41 of the inner sealing layer 4 in the air duct groove 11, the inner sealing layer 4 is positioned on the seat foam 1.

[0114] Exemplarily, the material of the inner sealing layer 4 is a metal material or a plastic material.

[0115] Preferably, the outer sealing layer 3 is attached to the inner sealing layer 4 to facilitate the formation of an air duct in cooperation with the groove 41 of the inner sealing layer 4. When the outer sealing layer 3 is adhesively connected, the outer sealing layer 3 is not only adhesively connected to the seat foam 1 but also adhesively connected to the inner sealing layer 4.

[0116] Preferably, the overall outer contour of the inner sealing layer 4 is rectangular; for the area size of the inner sealing layer 4, please refer to Figure 2 , and preferably the inner sealing layer 4 can cover the air duct groove 11 and the outlet groove 132.

[0117] In an embodiment where the inner sealing layer 4 covers the outlet groove 132, the outlet groove 43 cooperates with the outlet end of the fan assembly 2, the outlet groove 43 is in sealing cooperation with the outlet end of the fan assembly 2, and the outer sealing layer 3 is attached to the fan assembly 2. Specifically, please refer to Figure 2 , the outlet groove 43 includes two oppositely arranged outlet groove side surfaces 432 and an outlet groove bottom surface 431.

Please refer to Figure 11 , Figure 11 For Figure 12 the cross-sectional view at A-A in Figure 12 which shows that the outer sealing layer 3 is attached to the fan assembly 2 and the fan assembly 2 is attached to the outlet groove bottom surface 431. Since the left and right side surfaces of the outlet end of the fan assembly 2 are in contact with the side surfaces of the outlet groove 43, the top surface of the outlet end of the fan assembly 2 is in contact with the outer sealing layer 3, and the bottom surface of the outlet end of the fan assembly 2 is in contact with the bottom surface of the outlet groove 43, it can ensure that the air outlet 212 and the air suction port 211 of the fan assembly 2 are spatially isolated to avoid air return.

[0118] In an embodiment where the inner sealing layer 4 does not cover the outlet groove 132, refer to Figure 4, two outlet groove sides 1325 opposite to the outlet groove 132 are in interference fit with the circumferential side of the fan assembly 2, the fan assembly 2 is in contact with the bottom surface 1324 of the outlet groove, and the outer sealing layer 3 is in contact with the fan assembly 2. Since the left and right side surfaces at the outlet end of the fan assembly 2 are in contact with the side surfaces of the outlet groove 132, the top surface at the outlet end of the fan assembly 2 is in contact with the outer sealing layer 3, and the bottom surface at the outlet end of the fan assembly 2 is in contact with the bottom surface of the outlet groove 132, it can be ensured that the air outlet 212 of the fan assembly 2 is spatially isolated from the air inlet 211 of the fan assembly 2 to avoid air return.

[0119] In addition, by the sealing fit between the outlet end of the fan assembly 2 and the outlet groove 43 or by the sealing fit between the outlet end of the fan assembly 2 and the outlet groove 132, it is beneficial to fix the outlet end of the fan assembly 2 and facilitate the further fixation of the fan assembly 2.
